Turbo exhaust

There is a guy I saw at the track 1 day w/ a turbo that is at the rear of the car just before the tailpipe!? :rolleyes: I didn't get to get to ask him about it. I saw him on the road yesterday and it reminded me about it. Has anyone seen or heard of this, or are you guys just going WTF? Any kind of info(gains,cost,just wtf)?

Yeah, I am pretty sure its called the STS turbo kit
http://www.ststurbo.com/ls1_camaro_kits

So who has this? Sounds too good to be true.

do you remember what the guys car ran ?

That seems like a pretty sweet deal to me.. If those dyno charts on the site were real than that seems like a REALLY awesome turbo modification. I watched the video on how it worked and it seemed like it could work, but I don't really know too much about turbo's.

Sorry, I didn't see his times, it was a busy night. A guy I was talking too about it there said his times were not too great. For $3700 and no extra mods, that is a good pwr to $ ratio, is it not?

Anybody here w/ this?

i cant imagine what the turbo lag must be!!

and i can't imagine the turbo would last too long on a daily driver. imagine all the dust and water that the intake would pick up, not to mention the corrosion on the turbo and components themselves being under and behind the car like that!!

i suppose for a garage queen or a trailer beauty it would be cool...but i think i'll pass for my daily driver

I had the system put on my convertible last October and went through a pretty wet and snowy winter, driving it nearly every day. Maybe that wasn't smart on the salt-the-road days, though;-). I had a precharger bag on my filter to reduce the garbage that might get through.

The 7 lb system took 2 seconds off my G-tech quarter-mile time, before I did any tuning, and with the pre-charger bag on there (which I've since learned restricts air flow quite a bit). I've since tuned the car but haven't gotten out to run another quarter mile. So, before tuning, I went from 15.1 to 13.10 (I'm at 4500 feet above sea level). The 13.10 had two people in the car besides (both runs were G-Tech Pro). Everything else is stock on my car, including the 245/16 tires. They just slapped the turbo on for me in an afternoon, and I've done my own tuning (very slowly, with Tunercat).

If you're not interested in tearing your car to pieces to do the install and want great power for the $, I think this kit is the answer. The driveability is awesome, and the exhaust note is a little beefier at cruise, and a lot louder at WOT. By 3500 RPM, I'm at full boost. Not the boost response of a roots blower, but I don't think centrifugal superchargers can do that!

This car is so fun to drive, I'm leaving my 2000 Vette home! I can't believe I went so long with my slow Z28 before making the jump. No LT1 should be without it!

Damn, that sounds like a sweet set up. 2 seconds?!!?!? Those are awesome results.

I was looking at the G-tech results. And the 3rd comparison run says Methanol Injected @ 50%. And that ran them a 12.5 @118 with 7 psi.
Think the Methanol had more to do with it than the turbo did?? :confused:

Anybody w/ a LS1 w/ this on there car? 2 seconds off 1/4 times? WOW, for the $ that is good right.

I sell and install these kits. On my stock '02 Formula, it makes 412/451 @ 5psi. Driveability is completly stock until you get on it. It carries over 400ftlbs from 3000 past 5000. Gets great gas mileage. Its easy to install.
I have had mine on for about 5 months and its great.

That's badass.

There are kits for LT1's, full size GMC and Chevy trucks with v-8s, Toyota Tacomas with the v-6, and Toyota Tundras with the v-8. There are tests that have an LT1 putting out 589rwhp/637 rwtq at 12psi. The LT1 takes boost a little better than the LS1.

Isn't 12 PSI a little high for stock internals on an LT1?
Are there any Dyno numbers for one running at around 5 PSI?

The 12psi was with meth injection and a good tune. Stock numbers @5psi for the LT1 are 350/390; completely stock. The LT1 can take more boost mainly due to piston design.

I don't get why everyone thinks this :confused: If this were the case why are there not methanol injection kits everywhere for NA cars? The methanol allows more timing to be run because of it's high octane content, it also adds an itercooling effect. Any car with a turbo that adds an intercooler and runs higher octane gas to run more timing is going to pick up power... Right?!?!? :eek:

Trtturbo, no track times?

Gotta chime in with my standard "STS, the Powerdyne of turbo kits." :p

I'd like some track times too, with 5 PSI of boost. 12 just seems too high, but then again I don't know jack about this kind of turbo.

On these kits, the primary use for the meth is to cool the charge temps.We dont use intercoolers since the charge pipe is exposed to ambient air as well as the turbo running on average 500 degrees cooler. The reason for meth is no matter what, your charge temps are going to raise under more boost. I dont run the meth on my car because I only run 5psi. For the customers who want to raise the boost, we usually set it up so when you flip the switch to raise the boost, you also arm the meth. The meth starts to spray at 4psi. It is wired in with an injector so that it only pulses when the injector pulses.
This way you dont overload the engine with meth.
I dont have any track times yet. My car is a 6speed on stock GSC's so lauch will never be good. I do need to take it out just to see though. The "seatofthepantsmeter" says it should do well.
If any of you are in the Dallas area and want to check it out, just let me know. I would be glad to give you a ride.

My son just bought a '94 LT1 car and should have a system on it before too long. Will keep you updated.

:thumb: Sweet.

Does the 3600 bucks include install?

It does not include install, but I only charge $300.00 for the install. It is that easy. The kits come with very detailed directions. Anyone with average ability can install one in a day with basic tools.

The 12psi was with meth injection and a good tune. Stock numbers @5psi for the LT1 are 350/390; completely stock. The LT1 can take more boost mainly due to piston design.

12psi was not stock. 12psi was on forged pistons, ls1 rods at the very least, and I've heard mixed wording that it was also a 383 engine.

If you try to tell me a hypo piston and the factory pins can take those forces and I will never believe you. Nitrous on an lt1 I can see, but the heat you're talking about here will crack the pistons, blow ringlands, or heaven forbid destroy the pins. The stock pistons have the ringlands too high for a good boost setup.

If guys are running intercooled superchargers and blowing ringlands at 8psi, 12psi is asking for trouble. Methanol helps to advance timing and deter detonation, but there is a point where the heat alone is going to start causing problems.

The STS kit is easy to install, and it's cheap. And it's creative. And it is "the powerdyne of turbo kits" and there are a lot of guys running their kits. There are also a lot of guys running a hot cam. It works, and I wont dispute that. You will have to decide what you want from your car and where you want to go.

Look at their dynos. Loot at their slips. Think of where you want to be. Think of that. Realize all those numbers werent necessarily on a stock shortblock. Read the complaints, read the compliments. Look at the guys who want lots of power and see where they went. See if you want to go that way.

And I'll give you this as an example, from my own setup, I've put $3340 into it (BOV, turbo, headers, downpipe, wastegate, oil ines, pipes) and I'm ALSO going to get an intercooler in another month. And my turbo is good for 800rwhp easy (I dont need to pay for an upgrade). I've done no fabrication work. Install is as easy as installing headers.

Again, search. Listen to all the guys that have gone each way and decide where you want to be. I nearly went the STS route - but I wanted something to make more power, be more efficient, and be cheaper. So I bought what I needed and made the kit myself. I want 800flywheel HP at 14psi on pump gas. What do you want?

Most people cant make a kit themselves. There are also not many people who can install a traditional front mount turbo. I put the turbo on my stock, yes stock, LS1 and made 412/451 @ 5psi. No modifications to make it fit. No searching for a particular part. Just follow the directions and put it on.
If you want more power it is easy to expand. There is an LS1 with forged rods and pistons, LS6 cam, LT's, and fuel making 570 at 10psi. No head work, not much of a cam and great power. This car is using a t-67 with the meth injection.
I am not saying this is the only way to go turbo, but for someone who wants a kit they can install themselves and get a nice gain, its a kit you should consider.

What are the IATs looking like without methanol injection?

IAT @ 5psi w/o meth is 115 degrees.

12psi was not stock. 12psi was on forged pistons, ls1 rods at the very least, and I've heard mixed wording that it was also a 383 engine.

If you try to tell me a hypo piston and the factory pins can take those forces and I will never believe you. Nitrous on an lt1 I can see, but the heat you're talking about here will crack the pistons, blow ringlands, or heaven forbid destroy the pins. The stock pistons have the ringlands too high for a good boost setup.


Heat will not crack the stock Hyper pistons... Detonation does. Grab a set of 78cc combustion chamber AFR heads, slap them on the stock shortblock and I bet the pistons will live a long happy life. The lower compression due to these heads will give a safety cushion in the tune. FWIW many stock turbo cars run hyper pistons. 10.5:1 is just to high for forced induction, detonation does usually happen to all but those with the best of tunes, thats why all those 8 psi blower cars are, well.... Blowing :D

It isn't the Hyper's fault... It's the car owners (and I'm one of them)

Bill

IAT @ 5psi w/o meth is 115 degrees.

What was ambient temp at the time of that run?

I dont know the ambient temp, but if it helps, the turbo outlet temp was 175 and the intake temp was 115. At 8psi the turbo outlet temp was 225 and with the meth, intake temp was 70 degrees.

IAT @ 5psi w/o meth is 115 degrees.

I meant what were the IATs at high boost levels without methanol, or has anyone had the balls to try it. I dont want to have to run methanol just to be able to run boost levels that any other kit doesnt require methanol to run.

keep in mind, we dont run an intercooler. To run higher boost, you need to do something to cool the charge temps. I had the 8psi with meth on my LS1, but changed my mind with stock fuel system and pistons. I would not run the 8psi w/o meth. The thinking behind these systems is outside of the box, but I personally am very satisfied. Check out the FAQ's on www.ststurbo.com

Yes, you could use and intercooler. I just sold an kit to someone with an Augostino turbo motor. He is using a t-70. Should make great power.
It would just be a matter of fabbing up a pipe to go to the intercooler, then from the intercooler to t.b.

So no times on these w/out any other mods?

some are running low and mid 12's, but with great mph- 117 to 120 with street tires and high 60ft times.

Has anyone measured the lag time on the STS kit vs. a standard turbo setup? Seems like a real long trip for the boosted air to travel. What about pressure drop measurements from turbo outlet to intake manifold?

I thought alot of the STS guys were seeing full boost by 3500 rpm. It has the same characteristice of my kit, but I'm turning 2 turbo's. When the boost finally does hit... hold on :eek:

My car hits full boost at 3000. In first, its almost useless; just spins when it hits boost. I usually short shift 1st a little. In second, on all but good pavement, it spins more; just back pedal a little and go.

Would this be useless w/ a auto?

I rode in an auto & a six speed before deciding to make my purchase. 6 speed is a LOT of fun, but that auto will probably always beat it at the track because it's easier to get a great launch and you don't lose boost during shifts. If they had a kit for my auto vette, I'd be signing up for it. I keep telling Rick to find some time to get a vette kit together.

So you think that a auto would spoll up on line better than a stick, how?

You cant build boost by reving the engine; there has to be a load. You can stall up an auto. Also, you dont ever get out of boost with an auto. With a 6speed, everytime you shift, you blow off boost.

I wish he would get a Vette kit together too. I think it could be made to fit. There may be room where one of the mufflers is at.
My car was in the Dallas Auto Rama and I had alot of C-5 owners ask if we had one for a Vette.

Methanol is just a knock retardant and cooling effect and octane booster it is not a power adder.


I was looking at the G-tech results. And the 3rd comparison run says Methanol Injected @ 50%. And that ran them a 12.5 @118 with 7 psi.
Think the Methanol had more to do with it than the turbo did?? :confused:

You can launch under boost with a manual. Get a stutterbox or a controller with a "launch" feature - DSM guys have been doing it for years with the AWD... It just temporarily changes the rev limiter to your desired launch rpm and keeps it just "blipping" there. If you can get the RPMs that high to spool a v8 (3500rpm or so) and launch at that, then you're good to go. But I tend to think a 3500rpm launch under boost on a manual would instantly nuke a 10 bolt :D

Really :confused: So by cooling your intake charge thus making it more dense you won't increase power? You have a few things to learn.

Reread the post there smarty. So why isn't everyone running Methanol??? NA guys anyway?? Because FI guys have enough heat to do some actual cooling thats were the gain is. so read before you speak :alert: So if you dont have heat or knock methanol wont do much maybe 1 to 2% gain.

So if you use it and gain power, what the hell is it?

I wouldnt pretend to speak for anyone else, but on this kit we use it to cool the charge temps. It can give you a little gain, but we just want to make sure the charge temps are good.
As far as building boost by reving, with my stock clutch and 7.5 10 bolt, I will just leave it as is. I am working on a built motor with TH-400 and bigger rear end in a truck and a 2-step (stutter box) is a strong possibility.

then I guess it's nitrous :rolleyes:

"You" have a few things to learn. The meth. dosen't add power, lower IAT's and dencer air as a result of the meth. is what makes more power. Pay attention next time. :irk:

More a matter of semantics....that's like saying that a S/C doesn't add power it's the additional air and fuel in the cylinder that makes the power.

In the end yes methanol does make more or give you the ability to make more power as does race gas, intercooler, nitrous, blah blah blah.

Thanks Pwrhngryj :D

all meth does is cool the intake charge and control combustion enough to allow you to run higher boost (well, it does some other things too but the effects aren't as pronounced). You could say its all semantics because it allows you the ability to get more power, but along those lines running headers allows your engine to make more power, so what difference does it make? It doesn't in itself make more power, in fact if you dump a bunch of methanol on an engine that doesn't need it your more likely to lose power than gain it since the fuel charge will be diluted. Methanol doesn't produce the heat that fuel does, and it burns slower

No Prob. And to SMOKNZ and GhostZ, nitrous adds power by injecting a mix of nitrogen and oxygen (N2O) into the engine "the nitrogen makes up two parts of the mix and the oxygen one", to which more fuel must be added. This mix of N2O and fuel together drematicly boosts your cylinder pressure during combustion. "That is what makes more power and is the same idea behind turbos and blowers. the power added is a "DIRECT" result of the nitrous, turbo, or blower. And that is what makes them power adders!!!!! HA. Meth cools the air, the cooler air makes more power by alowing you to burn more fuel. "NOT A DIRECT LINK" the cooler air is the power adder in this case; "NOT THE METH"!!!!!!!!! Now I suggest you either go back to school and doo some learnin or shut your mouth. B!T(H

You're making friends fast.... :rolleyes: Stop insulting people, it makes you look like an ass.. And BTW, only the most insecure people must resort to insults in order to prove themselves. And I suggest you go take an english class.


I'll go back to school now, and do some learnin' and shut my mouth :rolleyes: :D

Thanks to all who have my back!!!! :thumb:

No Prob bro. any time :cool:

Ricers need Nitrous like old men need Viagra.
For the rest of us it just makes it more fun.

Thanks for the chemistry and thermodynamics lesson. It was very educational :eek: I was wondering what that 2 after that N meant. :bow: You forgot to mention the cooling effect that nitrous adds to boosted vehicles, which is why one usually gets more power for a given shot of nitrous than an NA car. But what do I know :confused:

Hay, did we forget what we were talking about? :p Has anybody w/ this stock, or almost stock run this at the track?

That's what i want to know.

I don't know any times but on V6F150.com there is a truck with a kit like it (home made) that is making about 270 HP and 311 FT/LB at the rear wheels on 7 lbs. of boost, it still needs more tuning and he still hasn't added an injection kit. :eek:

Apparently you are missing the entire premise of my post and others and it's really not worth my time to try and explain it to you in a more elementary way.

Have a great day!

a stock heads and cam ls1 ran a 11.8@118 (auto) and it had a fuel pump problem too aparently they found out, it was on 8psi

So it had a built shortblock then? What cubic inches? a built shortblock hardly qualifies an engine as stock :rolleyes:
