STS Turbo

I got a question for the STS Turbo owners out there...

I wanna get one for my car, and was planning on running a 7psi boost on my stock engine with the mods listed....

Will i need to upgrade my injectors? i know i will need a computer tune. that is a given, if only for the fact that i need to raise my rev limiter and remove my speed limiter.

Also, will my engine be able to handle it for a while? at least until i get it rebuilt specifically designed to handle the increased power and RPM's.
Can my stock rearend and tranny handle the extra power? :p

Any help would be appreciated...

at 5 psi you may be OK, but any higher you'll be fine if you get the METH kit, otherwise no.

You will need to upgrade your fuel system to run 7 or 8 to be safe. You also will need either the meth/alky injection or a FMIC. If you have long tubes, you will have to get the LS1 kit to clear them. With a good tune, your engine should do fine for a very long time, unless you are constantly dogging the hell out of it.

Oop, almost forgot a very important thing....

will the kit clear my SLP X-Frame SFC's? ????????? i kinda have em welded on. :D

nope... they gotta come off.

or the drivers side does anyway...

I believe the LT1's keep their SFC's. Check the pics out on STS's site. LS1 drivers side SFC has to come off if you already have one on there.

From the horses mouth. This is the email I got when I asked that same question about my LT1 car.

James, you pretty much need to change out the left side sub-frame connector with ours. It is designed structurally to work as a sub-frame connector in place of what you have and you will definitely get more power out of it. If you want to give me a call some time I would be glad to answer any questions or anything else. Thanks. Dave.

Either David is confused or they changed how they are making them. Here is a picture from STS's site showing the install on an LT1. See how the intake tubing comes back towar the middle of the car away from the SFC.

http://www.ststurbo.com/inc/iview/264?idx=7&p=8565

The LS1 kits have the pipe that runs in the sfc channel along the drivers side.
The LT1 ktis run up the center. If you have an LT1 with long tubes, you have to use the LS1 kit to clear the long tubes.

WOO HOO!! Awesome. that means i ain't gotta chop it off WOO!

Hey trtturbo, what sorta prices you guys got on the best turbo setup for the LT1's? i wanna get the best one, that way when i rebuild my engine i won't have to spend more money to get the better setup. i plan on just running my stock engine with the 5psi, and then when i rebuild and tune it, then run higher psi. Thanks

i wanna get the best one, that way when i rebuild my engine i won't have to spend more money to get the better setup.

The best LT1 turbo kit, or the best STS kit? :D

I am getting an STS Turbo kit either way. i don't want none of those "cramp up the engine bay even more than it already it is" kits. I want the best of the STS turbo :D

Besides...trtturbo only sells STS kits. that's why i asked him.

WOO HOO!! Awesome. that means i ain't gotta chop it off WOO!


I dont think you do unless you have Long tubes. Your sig says edelbrock shorties, so they should tuck up fine with their y-pipe.

how do the sts kits avoid lag? only thing i can think of is they use smaller diameter tubing for the pressure pipel, but that would restrict flow...
so can anyone explain?

They dont avoid it really. It's been shown already that they spool head units very similarly to a 3.0 liter supra motor, on a V8 5.7 liter F body.

Heeeeeerrrre we go again... :rolleyes:

Heeeeeerrrre we go again... :rolleyes:


I love when STS people get offended when someone else states something about the kit that demonstrates the negative characteristics of such a design. :cry: :cry:

Im not going to feed your little STS bashing rampage... Ill leave it to you to hijack yet another thread. Have fun kiddo.....

I'm not bashing STS at all. You're just pitching a childish fit because I'm pointing out how the kit will behave. I'm sure you're even more pissed that I'm right kiddo :rolleyes: :D

Umm yeah...i designed this thread so that i could get a few little details about the STS Turbo kit. I already know all about the very minimal turbo lag...i know all about the turbo...i just wanted to make sure i wasn't going to have to remove my SFC's. so if you will be so kind as not to point out the negatives about the turbo, and not get into childish arguments, then that would be great. otherwise, just don't even bother posting any replys to this thread. Oh and as for you loving it when STS people get offended...why don't you get off your high horse of "my turbo is better than yours" and go pester someone else's thread. Yeah. don't reply to this post anymore 5.0THIS. I am asking you nicely. don't reply.

That's a pic of my LT1 see more pics on our site. The good thing about the LT1 kit is that all the piping fits very nicely up in the body of the car and leaves no clearance issues. We are in the process of tunning our new 355, and going to see what it will do with the 60-1 and meth before upgrading the to the GT series and adding the FMIC. We have 36# injectors in it now, but the 42s are a good choice and tune nicely too. Definitly go with a tune to make it safe. I ran the LT1 for a year with stock engine and meth, 3psi low boost and 7psi high boost with meth/water.

What kind of times are those STS systems running?

What kind of times are those STS systems running?

Depends on how the car/truck is set up and who is driving. ;)

Yeah definitely give me the updated info on the turbo 355 setup. i am planning on rebuilding mine into a 355 as well. maybe 383 stroker, but i haven't decided yet. as far as i can tell i won't have any problems with my subframe connectors...And you say that are no clearance issues? excellent. this is all very good news. :D

blahster, sent you a pm.

might i add that i worked for sts for over a year and now that i dont i can still say that they work however they are not as efficient as a front mount, but most people dont want to cramp up their engine compartments more nor are they looking to run 8's so best turbo bang for your buck. i still run my kit as a remote mount however if i want to run faster than my current 10's then i will do something different. i just get tired of people ragging on the design, yes there are some downsides but every system has its +'s and -'s
just wanted to say that for a while
as for the original thread
get that thing tuned and get a wideband cant stress that enough, key is to pull timing out and watch your a/f ratio if you want more than 5 ps1 i recomend the water injection
my 2 cents

Plus check out Februarys edition of CHP, the magazine did a full length article about STS. I am sure that there will be some more business generated with that one. Also they won GM's aftermarket design award last year as well. All I can say is that GM thought enough of their design to warrant their award and that means something. I too can say that I don't have any personal experience with their product other than riding in one, and witnessing what I saw of their product in action at SEMA this year. But I did like what I saw and I wouldn't hesistate to recommend a kit to a person that wants some instant gratification on a stock setup. A totally modded setup I am sure will be different but for a stock system I think it would be just fine.

i ran 12.4 untunned but i feel confident that i am in the low 11's now

So when did you run 10s??? :confused: 12.4s out of a turbo 383 sounds pretty crappy to me... :rolleyes:

Out of curiosity, what are the STS cars running? How about STS owners post up some times :)

hehe :p You are one of the quicker STS vehicles as far as I know, so I should have said STS vehicles ;) :D

Just for the record, and no offense to Jose, but besides 2 customers that havent produced timeslips (none that I have seen anyway), PTK hasnt had an fbody customers showing track times. I remember Jose conveying the info to us, but it would be nice to see a slip or video in person.

How about we start a thread that asks for track times for turbo cars only. You'll have a bunch of guys with STS cars replying, nobody with PTK replying (unless Jose does it), and possibly a few TTi replies.

Oh, and for the record, if PTK's price is right i will get the hotparts from them, but I know what an STS car can do and I respect them.

I totally agree realquick. PTK hasnt posted the results, STS has at this point. STS has made a lot of kits and sold quite a few of them. So far so good, right?

Most of us now know advantages/disadvantages, and we need to keep control of that.

Now that I'm snowed in up here there is no chance of making it out till spring - another 3 months away (and I havent driven my car since July of 03!) but hey, that's just how things go.

I've been a strong supporter of a fbody track day or dyno day and let the boosted cars get at it. Maybe come spring we'll get that chance. Might as well let it sit till then... well... atleast us folks up north. :)

But as a PTK/Custom myself, I have to say I'm a bit biased.

:cool: I am in MA, just finished snow blowing 8" of snow about ~3 hours ago :) Like I said, I am going to go front mount for sure (most likely PTK hotparts with the Precision T76 I already have), but some poeple on here like 5.0this always try & take shots at STS whenever possible.

ok...saw a ls1 put one on. Went 12.2 with bolt ons and stock converter/stock gears on a 1.7 60'. Put on sts kit..no other change. Best pass was a 12.7 on a 2.3 60'. The only change to the car was the addition of the turbo. It picked up 100 dyno hp and over 100 dyno tq...by 6200(I think) the NA power curved passed the STS curve as it was falling like a brick. It picked up 3mph over the bolt on mph.

PTK has the fastest lt1 boosted f-body out here. 8.3 at 165 or something like that.

Sounds to me like the guy's sts needed tuning, not to mention he lost .6 in the 60' due to his launch which translates to an easy ~.9 in the 1/4. I saw one 03 cobra trap 108 stock, so they are all slow...????? Its kind of hard to lose ET with atleast 100rwhp/100rwtq when comparing the STS to N/A. Before anyone says the STS is too peaky, and area under the curve...look at any dyno of an LS1 before and after the STS install. Area under the curve is way more with the STS system.
I have taken a ride in 2. A relatively stock T/A with 4.5psi (which felt as fast as my heads/cam LT1, and its track times proved to be the same) and Purevil's 630rwhp 10 psi monster. his sts kit got his car moving.
As far as PTK's fastest FI fbody, are you gonna run into him on the street? I know mustang guys are loving the PTK stuff, and like I said before, i am probably going to use a PTK hot parts kit. However, just because Jose lists two customers that dont show slips/dyno numbers to us or Jose for that matter (he could post them if they did), it just shows you which kits you will be more likely to see. I am hoping people post PTK stuff soon. Perhaps Jose has shown slips, I havent seen them to my knowledge. I would just like to see more results from people on the boards.
As far as STS dyno curves, I have seen purevil's dyno when it was tuned on 10psi. Its a nice compromise between a blower and front mount. It makes peak torque/boost before the blower, but after a front mount. However, in lots of cases with some of the high powered fbodies on this site and others, his rear mount actually peaks the same as some front mounts. I believe in general though, thats not going to be the case for most others.
For those that want more power and torque then a typical off the shelf S/C (like a D1 or S/T trim) then STS is a great, clean kit.

Right here 11.6 @120 on stock heads cam and 2.0 60'. No it wasn't set up at the time to boost off the line, but this was a little while ago now.

JLTurbo 11.6 run (http://www.jlturbo.com/vids/jlsts.wmv)

I think it would be a REALLY great idea for 5.0 THIS to start his OWN thread about STS questions for the simple fact it could POSSIBLY keep him from fawking up and derailing other STS inquiring threads, just like we see here. Its getting REAL old...hell, the thread starter for this thread even politely asked him to not post but what happens? He asks a question in this thread that has NOTHING to do with the original question.... nothing new.

Nice numbers. Your were doing as well as a guy from this site:

http://www.turbomustangs.com/forums/showthread.php?s=&threadid=19380&highlight=Cam+Motion

There was a guy with a LS1 TTi system and a turbo cam and only ran an 11.3 @ 120mph with 6 speed. I am not trashing this guy at all, I just wanted to mention it. I know the TTi street kit has log design on one side, but it goes to show you that not all front mounts are better than the STS kit.

Yeah the 11.6 was stock heads and stock cam and very poor converter, not built for all the power. This was before the heads/cam, FMIC, and Pro Yank converter. Track reopens Jan 8 so new times will be up very soon.

Logs suck :) End of story.

That 11.6 run - there's more in there. That 2.0' 60ft really kills the car, but you can see it just zip down the track. Looks a lot slower then it is. Good to see it go...

I'll post my results in the spring... but STS sells, gotta give it that. As long as we stay faster then the imports, I think we're good, no matter how we get there.

Wow, I cant even ask a question in here without you to jumping on me. Funny, neither of you jumped on the other guy that asked the same ****ing question!!!!!!!!! I asked it again because no STS owners were posting times.


Avengeance, feel free to shut the **** up anytime you stupid newbie. I already PMed you to keep it out of this thread, so I suggest you do the same if you have any further issues with me. OR by all means, hit me up on AIM.

Now, back to the regularly scheduled topic ;) thank you LukeZ28 for posting your times, thats all I wanted to see. Nice times BTW, those are the quickest posted times for an STS car that I've seen yet.

Can you tell me a little more about your setup? I plan on running a 383 with T76 front mount. Looking for 700rwhp w/15psi on pump gas. I am still up in the air about a cam. Cam Motion recommended one, but it seems a tad small.

5.0this - I mentioned you because I always see you in these threads.

Sent PM to keep from hijacking this thread :)

I'll have my PTK kit in a few weeks, so hopefully I'll be able to post some numbers soon with my LT1.

GS355

I asked it again because no STS owners were posting times.



Geee... I wonder why... could it possibly be that this thread has *gasp* ABSOLUTELY NOTHING to do with STS owners posting track times? :rolleyes:



Now, back to the regularly scheduled topic ;) thank you LukeZ28 for posting your times, thats all I wanted to see. Nice times BTW, those are the quickest posted times for an STS car that I've seen yet.

Thanks Luke... but how bout not feeding this kids need to hijack STS threads. ;) :lol:

Grow up... Just because someone asked about something related to, but not exactly on topic is nothing to get all pissy about.

Thanks 5.0 This for posting that question as I was curious about track times with the STS kit. I have always been really skeptical about this system and it dosnt make sense to me, but I guess it works.



Now lets see if I can upset this little girl even more by asking another question about the STS...

Where do they usually start making boost? With all that piping, Im really curious.. Ive got a friend that was debating this system with me, and the answer to this question might just settle it.


Thanks guys.. And remember to try to not get your panties in a bunch.. People asking questions and people answering questions is how we learn, its not Hijacking... Grow Up!!

Hey.. smart guy.. seems you have some Qs about the STS kits. Maybe starting a new thread with the topic being "STS 1/4m Times?" or "When do STS kits start making boost?" might be a excellent idea for getting the answers you want. Or, perhaps, you could REALLY use your head and try the search function instead. Just a thought... :o

Sounds to me like the guy's sts needed tuning, not to mention he lost .6 in the 60' due to his launch which translates to an easy ~.9 in the 1/4. I saw one 03 cobra trap 108 stock, so they are all slow...????? Its kind of hard to lose ET with atleast 100rwhp/100rwtq when comparing the STS to N/A. .


people asked for actual results and i posted them. The car WAS dyno tuned..it had a major problem getting out of the hole and building boost..I quote "that POS couldnt get out of its own way before the 300' mark". It killed the low end of that car. They say the car is fun on the street and "feels" fast from a role so they are having fun with it. So..like i've always said about this kit..if you want the "neat" factor and are too intimidated to install a front mount turbo and don't care about track times this is a descent kit. It will make the car alittle faster on the street. Ive seen it and have some concerns about how it is mounted..I feel the oil feed tube mounted on the bottom is a disaster waiting to happen(this one has already smacked the road twice) and i think the return piping is too low and in a bad place right in front of the drivers side rear wheel..once again..a problem waiting to happen in my opinion. But if you do want to kick ass at the track there are better systems out there. And..just because no one posted the times slips or vid of a ptk kit doesn't mean it hasn't happened...I've seen some crapy results posted about the sts kit but people always say that it was their problem.not the kit. So when less than stellar times are posted of a sts kit there must have been a problem but unless you see the vid of a ptk kit(laying down some big hp and track numbers) they don't work..crazy stuff going on around here. And you may not see that 8.3 car on the street..but it shows that their system works. Where is the 8 sec. sts car?

Where do they usually start making boost? With all that piping, Im really curious.. Ive got a friend that was debating this system with me, and the answer to this question might just settle it.

I have ridden in an STS car. Here is my observation on your above question.... It started to make boost at 3500 rpm. When I say that I mean it went above 1 psi on the gauge or thereabouts. The car felt completely stock though until 4500rpm, when indeed there was a good rush of power. so I'd say it hit stride at 4500rpm, at which point it broke the tires loose, and then the car had to up shift very quickly. It just wasnt spending enough time in boost per gear, but again, just my observation, do with it what you like ;)

The LS1 car I saw that had the kit.... the pipe right besides the driver's rear tire was about the width of my four main fingers on my hand off the ground (didnt have a tape handy at the time).... so I'd guess like 3 inches off the ground.

As far as the PTK kit, the people who doubt the claims are going on the idea that Jose is completely lying his ass off when posting results from PTK cars (A stock motored LT1 6 speed car went 11.0@ over 120mph with the PTK kit, hardly a drag strip queen from the description too.. and another 6 speed LT1 with a PTK kit on a built 355 that went 10.0@ like 155mph) I'm still going on the assumption that he's not lying his ass of personally ;) It's a good working kit, and apparently to prove the results we need to hear it from the owners of the car, with pics of their timeslips, photo ID, vehicle's title, engine bay pics, in car video, and perhaps an indian head nickel and today's paper next to the listed items as well, just to prove it was today :D

Unbelieveable... :rolleyes:

Oh God.. Didnt I just tell you piss ants to grow up? How old are you? 10? Why dont you go cry to mommy that I was asking a question that was SLIGHTLY off topic, but still related to the topic at hand?

Jeez! Get a Clue PEOPLE!!!!

It's nice to know that all my threads get arguments going, insults thrown, and the like. I love it. NOT GROW THE F*** UP YOU STUPID A**HOLES!!!!!!!!!!!
All i wanted to know was some simple information about the sts kit. i didn't think it would escalate to this level. If you have no more good things to say about the STS kit, then just stay away from my thread. ONE more retort about what someone said and i will delete this thread completely! GOT IT? jeez. grow up.

Can't wait til i get back home tho. my car is just waiting for me to take it out. it's gonna be at least a year tho. dang. i gotta wait a year? man. of all the luck. anyway, anyone who has some good times for the STS kits, please post them. And enough talk about this PFK crap. i don't wanna hear it. Who cares about Jose and his hotparts? i don't

I understand why your pissed. Some people just dont know when to quit. I would like to respond to the last few posts though for clarification.

Personally I care about Jose and his hot parts.

In case you folks haven't been around the intrawebbernet or message boards for a while it is the nature of topics for them to get off track. Let's give an example:

Topic: What kind of fruit do you like?

I like apples

Well I like oranges!

That's a coincidence because my car is orange!

Wow my truck is orange too.

Hey that's a neat picture of your truck where did you get that lift kit?

Etc ad nauseum.

It's the natural evolution of a thread...the subject invariably changes. If you don't like it you should probably make your own message forum where you can Nazi Mod the hell out of it and keep the threads to the subject at hand. Until you do that you should probably just cowboy up and realize the nature of the beast.

So when less than stellar times are posted of a sts kit there must have been a problem but unless you see the vid of a ptk kit(laying down some big hp and track numbers) they don't work..crazy stuff going on around here. And you may not see that 8.3 car on the street..but it shows that their system works. Where is the 8 sec. sts car?

300' mark??? he should be well into 2nd gear (he should be in full boost as soon as he shifts into 2nd, so that tells me he should have been in full boost in 1st gear well before the 300' mark). Some people exaggerate...but thats fine. Its funny, people say it killed the lowend, but have you ever looked at a graph comparing before and after STS dyno numbers. Below is a GTO's graph. They started the STS pull about 500rpm after the stock baseline pull started. However, within 500rpm the torque on the sts car already was higher than the torque before the sts was installed. The area under the curve is so much more for the sts curve then the before curve.

As far as make the car a little faster on the street, thats not accurate. Its makes the car alot faster on the street. As fast as a front mount with equal mods, most likely not. I have taken a ride in a 630rwhp/600rwtq STS car at only 10psi. He runs 14psi on the street. That car hauls some serious groceries. My LT1 with traction is a low 12 car @ 114-117mph depending on tuning ad he would ass rape me in that thing. When the boost hits its like being punched in the chest. I have also been in a stock LS1 that had headers and 4.5psi STS. That car picked up 7mph with the 4.5psi. 7mph more than a little faster, and thats not alot of psi. Could a front mount deliver more mph with 4.5psi, maybe...but thats not being debated.

As far as les than stellar times, atleast people are posting them!! Jose referenced two cars, which is fine. I am not saying Jose is lieing, because I dont think he is. I think customers may exaggerate slightly unless they can provide Jose with a slip. One particular example, the stockish LT1 with 10psi that trapped 130mph. We are talking 30mph over stock #'s from only 10psi??? Thats unheard of. Again, I am not saying Jose is lieing, it would be nice to see some proof thats all. I wonder how many PTK kits are out there that dont have great times compared to the two example Jose listed. Should we assume that all PTK's stuff only gets sold to people that dont post on the boards??? I dont think so. Again, I am not bashing PTK (I plan on using their hotparts), but people want to compare the STS to PTK when it seems like there have been only two kits sold & running :rolleyes:

As far as 8 second STS...be real. This kit has been out for how long? It was designed as a street kit and you know that they cant put a big enough turbo back there to get it in the 8's.

I have ridden in an STS car. Here is my observation on your above question.... It started to make boost at 3500 rpm. When I say that I mean it went above 1 psi on the gauge or thereabouts. The car felt completely stock though until 4500rpm, when indeed there was a good rush of power. so I'd say it hit stride at 4500rpm, at which point it broke the tires loose, and then the car had to up shift very quickly. It just wasnt spending enough time in boost per gear, but again, just my observation, do with it what you like ;)

Sounds like something is wrong with that car. Purevil's car hits 10psi+ by 4000rpm on the street. Also, if you can read 1psi by 3500 and your in the car...you have the best damn eyes ever. It was hard enough for me see the 10psi and then look down at the tach. I assume the 10psi could be slightly before 4k. By the time you look down the rpms have increased. I seriously doubt you even saw 1psi and then looked down in a millisecond and saw where the tach was. If someone is excelerating in 1st gear, if it takes you a second to look down, I gaurantee the engine has already spun another 500rpms. That is unless he has his boost gauge on the steering column in front of the tach or if he has a huge dash tach mounted need the A pillar.


As far as the PTK kit, the people who doubt the claims are going on the idea that Jose is completely lying his ass off when posting results from PTK cars (A stock motored LT1 6 speed car went 11.0@ over 120mph with the PTK kit, hardly a drag strip queen from the description too.. and another 6 speed LT1 with a PTK kit on a built 355 that went 10.0@ like 155mph) I'm still going on the assumption that he's not lying his ass of personally ;) It's a good working kit, and apparently to prove the results we need to hear it from the owners of the car, with pics of their timeslips, photo ID, vehicle's title, engine bay pics, in car video, and perhaps an indian head nickel and today's paper next to the listed items as well, just to prove it was today :D

PTK has a proven setup for stangs already, so there is no need to doubt there product. HOWEVER, who is to say that the 2 customers are being 100% honest with Jose? That 11.0 was 130 I believe and then he blew the motor. Do you really think a stockish LT1 (bone stock motor) will gain 30mph over stock (130mph traps) with only 10psi and a t70 turbo? Seems like alot to me. Maybe the customer realy ran 123 or so and said 130 because maybe he didnt get a good launch and figured he would have gained more mph with traction??? Who knows? I dont see Jose as the type of person who will lie, thats why it would be nice if a customer actually faxed him or mailed him a copy to post. When there are only 2 cars out there...and neither one goes on the boards where they have been advertising this product, then people should hold off on comparing them to STS cars until we know for sure how big the gap is.

I'm just telling you what the driver said. And yes..it did kill low end...hence the crappy 60' times at the track. Same tire as running stock..no tire spin. But its a fun kit on the street. If thats what people are looking for and aren't worried about some of the issues that have been talked about alot on this board..then I say go for it. I think the owner plans onputting a converter and gear in the car to try and help it out. On a side note he said it doesn't feel like such a turd out of the hole on the street since it can spin the tires which helps it get into boost sooner..

As far at the ptk kit..I can't speak for Jose but I doubt he is going to this board and ls1tech and posting up bogus information. I know ptk are very well respected in the mustang world and lay down some good numbers. Why aren't more running them here..my guess is they are intimidated or lazy. Either that or they are just going for a "cool" factor and not that much worried about maxamizing their turbo setup. Its much harder to install a ptk kit than a sts kit. I hope to build my own within a year or so..we will see if that happens.

I wont debate the car your talking about because its not my car. However, common sense says that making adjustments to your launch technique will results in better times.

As far as PTK, like I already said, I dont think Jose is posting BS. I just dont neccesarily think all the correct info was given to him (especially from the bone stock LT1 guy). I would love to start seeing PTK fbody results, especially since i have a T76 sitting in my garage.

He was alittle pissed/dissapointed so that may have played into the 300' statement. And I would be too after the first pass was over 1 sec. slower than the week before without the turbo. The did get it down some and got back in to the 12s...but there were a couple of 13 sec. passes before that happened. Their first 60' was somewhere in the 2.7 if I remember right...so they did play with launch technique and brought the numbers down.

If I do the turbo setup..I will be going with a t-88 or something equal in size. But I too would like to see more numbers. Maybe someone should post a thread asking if anyone is running them. :p

There are several more PTK guys floating around here that dont speak up or arent finished putting every last detail together (myself included).

STS and PTK can never truly be compared as equals, as that was never the intent. STS is a street driven kit. That GTO made peak Tq at what, 4200-4300rpm? The dyno is impressive over 3500rpm, but I am suprised that the HP curve does not continue to climb, as is often commonplace with turbo systems. 450hp and 515tq... certainly reasonable numbers, though it just doesnt have some of the same putput as other "traditional" kits. A PTK kit is capable of more by design. It is also more efficient. These are things we know. STS makes power, so does PTK. PTK costs more, and that is what you pay for. I dont like how STS does things, but who am I to judge what other people want for their cars? Beauty is in the eye of the beholder. As is his wallet and his lust for power.

Another thing to remember is on the "Seat of the Pants" test, after driving seval LS1 cars, including a GTO and a 2002 WS6, my 95lt1 felt a lot faster. It wasnt faster then the Ws6 (GTO felt really slow) and we proved it against each other -- but that's an effect of the power curve. A hard TQ spike is what drives you into your seat and gives you that smack feeling.


Also people seem to forget load in the turbo equation. In a friend's old GST I could free rev the engine and build 2-3psi of boost by redline. Spinning the tires from a stop in 1st gear maybe 6 or 7. Gunning it in 3rd on the highway - instant 14psi. Load plays a huge factor in the turbo output, another blessing and curse of turbo systems.

A STS system is limited in many ways where the PTK is not. STS is a Street Kit. It is easier to install (but if youve pulled the engine out of an lt1 fbody you probably shrug at an underhood turbo install...) and that's how it is. STS is cheaper. STS puts the turbo in back. It does what it does. PTK does what it does.

If you really want to compare PTK vs STS - I bet a PTK car will be faster on the track (all else including traction equal) produce more power under the curve, be in boost longer, and the like. However the peak numbers will not be that far off. Depending on each exact car, they might feel the same or one feel faster then the other. That's all up in the air and depends on the car and the driver.

Now we all need to relax, grow up a little, and discuss this like civilized people. If it gets too far off topic, the mods will delete it. Obviously as it is still around it has some hope for becoming a decent discussion (though it has been debated in the past a thousand times and will be again a thousand more). I suggest people hold their tongues till we get some questions that can be calmly answered. If you want to piss at each other, do it in private over aim or something. People want answers and there are those that want to help them and educate the masses. Lets try to keep this under control guys. :)

This WAS a Great Thread. My car was even mentioned (btw John who took you in my car, was it Don). Anyhow, both sides cry all you want, but answer the Origial poster's questions.

My LS1 Kit: Basic STS turbo kit, Tial BOV, 42lbs svo injectors, Slowhawk LS1 edit tuning, LS6 valve spring, cromoly pushrods, FLP LTs, ported TB, FMIC and all custom piping by Slowhawk.
Tuning is a must, larger injectors are suggested, the longevity of the rear and bottom end are really in the drivers hands.

4.5-5psi = 416rwhp, 416rwtq 12.7@114.6, 2.097 60' on stock GSCs

FMIC + 8psi = #'s pending Tracks are closed for the season. Live with it guys. The numbers and times will be here once spring time opens the tracks. Purevl and I are anxiously awaiting for the tracks to open, just as much as you all want results!!!

I agree with both of you.....i was seriously not expecting for this thread to go up to 5 pages....wow. the longest thread i've ever had....lol.

I can't wait until i get my sts kit. it sounds nice. :D

ok...saw a ls1 put one on. Went 12.2 with bolt ons and stock converter/stock gears on a 1.7 60'. Put on sts kit..no other change. Best pass was a 12.7 on a 2.3 60'. The only change to the car was the addition of the turbo. It picked up 100 dyno hp and over 100 dyno tq...by 6200(I think) the NA power curved passed the STS curve as it was falling like a brick. It picked up 3mph over the bolt on mph.

PTK has the fastest lt1 boosted f-body out here. 8.3 at 165 or something like that.

Tim, I hate to do this to you, but I'm going to have to mention it. You say he added a turbo and was slower. Now, didn't you add nitrous and get slower? :D IIRC, you did, and why did you get slower, probably because your car is 100% setup for n/a. Just saying adding HP doesn't always mean quicker et's or mph, even in non sts cars. ;)

Where's Jose anyways? :confused: I pm'd him about a few turbo questions but got no repsonse and I don't see him in this thread either.

LOL..yea..well I put the jug on it for fun and posted my times..hehehe. it went slower shutting down way before the1000 foot mark. My 8th mile times were way up though..in fact..my 8th mile mph was 16-18 mph faster than my 1/4 mile time. :p This car went ballls to the wall full out runs..thats the difference. If he had let off or not gave full throttle like i did untill 30 ft out I could understand..but these were full runs. Oh..and same night ..I was only running 11.1s at 124 on motor so I actually went quicker.

As far as make the car a little faster on the street, thats not accurate. Its makes the car alot faster on the street. As fast as a front mount with equal mods, most likely not.

:D :bow: You should feel it now that its not pegged 10:1 and 16 psi like me and don ran before I put it away. 100mph burnout on 495. Also since I put that wastegate spring in and made some tuning changes its making 16 psi by 3500, makes 10 psi under 3k. Going good, shoud be sweet with the 402. I have posted many times on ls1tech, my graphs vs a few mods and users front mounts, I made peak ahead of one person and matched a mods t76 front mount, only difference was at 10 psi for both I was still 100 rwhp and 95 rwtq ahead of him by 5k. Its a dead horse, I dont even bother debating it anymore.

Nice!! Any new dyno numbers?

Nice!! Any new dyno numbers?

no its been sleeping for over a month. There will be plenty of that this spring believe me. I will push over the 800rwhp mark with this pos sts

Damn, you'll still spank me even if I have a Front Mount T76!

WOOHOO! I read all five pages of this thread and I didnt even get a lousy T-shirt! What the crap? :D

k, i got a quick question for the STS owners...if i may? About how much for a complete install for the STS kit with a 5lb boost? I found this thread because I'm thinking about installing a turbo in my 97 TA (now that she's completely paid for). but, if i'm doing my math right, which i'm probably not, i'm coming up to around ~$6k. that would include the kit, rockers, springs, pushrods, lifters, new timing chain (for good measure), tuning, controllers, guages, wastegate, blow off valve, possibly the snorkel kit or other means of re-routing the intake (i got to have two exhaust tips for the rear of the TA, might look funny if i didnt), possibly the methanol injection system (for future upgrades), and other miscellanious stuff that i'm sure i forgot to mention. oooh, better make that $6600. i better set aside some extra cash for some new tires. :eek:

i'm really not looking for the worlds fastest car here. just a little something to have some fun with either at the track or on the street. any ideas as to anything else i would need or not need? thanks,
dave.

ps- sorry if i'm jacking your thread. if you would like, i could make a new one.

edit: also, how big of a problem is adding any kind of turbo with the lt1 high compression?

Trtturbo, thanks for the PM. sent you one back full of questions. :D

A Basic 5psi STS kit will run you about $5500 installed. Then add pushrods, springs, intercooler, methanol injection, larger injectors. Your guess is right in the ball park i guess. I did all of mine for just under $5000, for reference.

Nice post Geoff!!!!

Like I've said before. It's all in how the car is set up when it comes to 1/4mile times...

With a converter or 2-step there is no reason why an STS car can't launch hard.

I do and I weigh over 5000lbs.... I avg. 1.80 60's now with 31" tall tires.

8psi launch then intake pipe pops off.

http://my.starstream.net/f8lpony/F8L%204x4%2012.95@94%208psi%20launch.wmv

Different angle, then a 6psi launch.

http://my.starstream.net/f8lpony/Justin's%20Runs%20-%20Small.WMV

Now I just need to disable the ABS so I can stay in one spot. LOL

Ok so back to MY car...lol.

What are some recommendations as far as the rebuild of my engine goes to handle the 12-15psi boost that i plan on running with my future STS system?
I am going to go with a 355 rebuild.
My goal is 600-700rwhp and about the same if not more on rwtq.

Gimme suggestions on Heads, cam, internals, everything. down to ignition, and who to tune my PCM. thanks!
