I just wanted to get peoples input on these systems. For $3,800 and the ability to do the install yourself it seems like a good deal.

I read articles in GM High Tech, Camaro Performance & Popular Hot Rodding that were all positive.

So, has any one rode in a car equipped with one of these?

What is your opinion on these systems?

Thanks for your input.

Bill

 

How can the transes hold that kind of power?

 

hey bill, thats what were goin to put on my pops TA. that kit looks awesome to me. I cant wait to try it. I think we'll step right up to the 7psi kit with the methanol inj. setup too.

mike, the t56 can take the power, but the clutch obviously wouldnt last. as for the auto, it would need atleast a shift kit to up the line press. along with a cooler. durability might be a prob. still with the auto at the drag's unless its beefed up internally. but thats nothing a th400 wouldnt take care of.

 

Chris, when you get it on your Dad's Trans Am I'd love to see what the installed kit looks like. It goes against my grain to put a turbo in the back considering you will certainly lose some efficiency back there, but it makes sense for some applications.

 

mike, have you read up on the site? they explain all that in the frequently asked questions page. the way they match the turbo case with the impeller makes for a very efficient turbo setup. they claim only 1/2 - 3/4lb boost drop from the back to the front at the engine. the piping goin from the turbo to the tbody acts like a intercooler cause it draws heat out like a big heat sink and the tubro itself he MUCH cooler running back there in the breeze and out the eng. bay. they also claim only .5 sec. lag time for the air in the pipe to get compressed, which translates into almost zero turbo lag AND all the boost is on under 3K rpm. that would make one helluvapower band for you at the roadcourse. also, if your eng. is built to handle more boost, they will custom build a kit to suit your boost range.

check out there site. all the info is there.

 

Bill, much more info on these kits and what people are finding out the limits to be on ls1tech. ( I auume of course you'd want on on an ls1). did you get a new car?

the best thing to do IIRC is to get the front mount innercooler, bigger turbo, and than maybe meth inj.

Thats of course, assuming you might want to make some decent power with one. Which then will require fuel, trans, rear, motor upgrades as necessary. lol.

 

Rodd,

I haven't bought a new car yet. I went to St. Louis a few weeks ago to look at a 2001 SS with a Vortech SC on it with only 9,000 miles on it. No go. I picked up a couple new lexus vehicles (GS300 LX470 Sport Utility)since I work for the company. Man are they nice riding cars.

So, I am looking for something with extremely low miles. I would like to find a plain jane hard top LS1 with an auto. I would be very happy with a car that will run 11.5s on the turbo. I would like to get a set of heads to help lower the compression so I can put more boost into the car. 12 bolt rear with a set of 3:23 gears so I still get decent gas milage and a 3600 stall to help get me out of the hole. I was listening to clips of the STS systems and man you can hear that turbo spool up. The link below has some clips from SEMA. STS's turbo kit was awarded the best hi performance product of the year this year. Turn up the speakers when you listen to the camaro launch clip. The turbo sounds is great.

So Rodd, what is up with your car? How did it run last season? Any new work done to it?

Chris,

When is your dad getting his kit? Is he going to opt for the bigger turbo?
Sounds cool. Want to help me with mine when I get it. I figure I install then take the car to some place like Livernois Motor Sports to get it tuned.

Can someone explain the meth injection system and why it is needed? Is this something you would need to refill like nitrous? How much would the sytem require and how much cost is involved after installing a meth setup?

Thanks,

Bill

 

Bill, good to hear things are doing well. If you hear of any decent non skilled jobs there, let me know. lol. OR anything that can involve an apprenticeship. heh.

anyhow, methanol inj is just spraying a water + alchohol mist into the intake stream to make up for higher octane requirements. Cheaper than running around on race gas, and if you tune it for 93, and use it when at the track or when hot out; you would have NO fuel worries. Involves a small tank, hobbs switch, and nozzle's and lines. The best reading on this stuff is on the turbobuik website. lots of those guys use it. cost? 4-500 bucks for a kit, or cheaper if pieces together. I think a place called whiteracing has em too.

ran the car some this year, but it had (and still has) the motor tick. starting to piece together parts now for a new shortblock. at m9 went 11.3 at 127-8 spinning on used up et streets. last year, went 11.05 at 129 on same setup, better 60'.

looking to make 600 rwhp on 10 psi, with a forged short. unported 6.0L heads w yella terra's and better springs. Have bigger injectors, kmember and a arms, and some other stuff to go in as well.

If your setup doesn't have injectors, my old 42's can be yours for a decent price. they will support 550-600 hp with a rising rate fuel pressure regulator, intank pump, and all else stock.

reason I went with bigger is so I can max out the turbo's. maybe get em to 700 on racegas? if not 650 will be enough .

 

Chris, yes, I've read the info on the site, as well as many threads on the subject. Basically mounting a turbo in the rear like this will be a compromise. You will have more lag to pressurize all that intake piping and will have more lag from the turbine being so far back in the exhaust. STS makes up for that by making a smaller turbine housing in their kit. This is fine for spoolup but now you're developing more backpressure in the housing when the boost does spool up. This increase in backpressure once under boost compromises the efficiency of the turbo. For low boost setups like 6 psi or so this is probably an acceptable compromise. If you want to build up from there though I think the weaknesses of the design principles would start to show.

I'd also assume you'd want to take into account the inertia of the long column of air in the induction piping when sizing your blow off valve. The kit does come with one right?

 

also, the meth. inj. system is how the system provides the extra fuel for the power increase of the boost. ontop of that, it cools the boost/air in the intake. which also helps with high boost tolerance. there is a blowoff valve, and I believe it has a elect. high/low boost switch for lower boost while cruising, and max boost/meth. inj. while in a race situation whereever/whenever that may be. you would need to keep the meth. tank full as if it were a aux. gas tank. so you'd need a supply of meth. alch. for when you wanted the system in full boost mode. another thing I like about the kit is that it doesnt require bigger inj.s due to the meth. inj. system. but ofcourse, I guess you could bypass all that by getting bigger fuel pump, fuel inj.s, and a custom tune. bill, this set up comes with basic tuning in a predater programmer according to there website. Im gonna look into it on LS1tech also.

alls I know is what I read on there site. so you can take that with a grain of salt. Id be very interested to see a kit installed myself. so bill if you do decide to do this, please let me do it for ya.

 

HERE'S a low mileage hardtop automatic 2002 Z28 for you.

 

Or for the right price I'll let mine go.
