STS on a drag car?
STS on a drag car? I'll be picking up a 98 Z28 soon to use as my track car. I'm thinking about going with the STS turbo kit (upgraded) with the intent to eventually build a forged iron block motor to handle up to 20psi. Am I correct in assuming that I can use an upgraded (larger) turbo on the stock motor with the boost set around 8-10psi and when the income allows for an iron block motor just bump up the boost?
Can I get some opinions on this? Would the STS turbo kit work well on a drag strip only car? Or would I be better off going with a large N/A motor setup? What I like most about the STS is the ability to run some decent times when I first get the car and just dial up the boost as the motor gets built.
Any suggestions welcome...I want to do this right.
Thanks

You can indeed run the bigger turbo on a stock motor. It will just be laggier.
As for using an STS for an all out drag car. Up to this point in time concensus is that it's not a great idea. So far at least, it's the hot ticket for the street but not proven at the track. I think most will tell you if your building a track car, go with cubes and N20. That is by far the cheapest and simplest way to go. Then again all this may change as those that are serious about making their STS a strip monster figure out how to do so. The Synergy car has a trip to the track planned for Friday. This is a stock motor with the bigger turbo that is capable of 15+ psi. Give Rick a call to discuss. Number in sig.

If you want a drag setup for a LS1, then you go with either the PTK or the TTI race setup, plain and simple. Spooling a T88 with a .96 A/R with a STS by sometime this week...ummm no....hehe, ain't gonna happen

It can most certainly be done.You will need an Auto of course.The right converter will spool the STS and the boost will hold steady on the runs.(I will release what HP these can make in a week or so 
)
But,If it is an all out race car and you want to be very fast in a budget,then Nitrous is the way to go.

Not to mention having to cut a hole in the t-top well so it don't drag on the ground. Don't get me started on trying to hold the thing up back there

Im running about the largest you would want to go I think. Gt70 sts. I also think its only good for 600ish rwhp with the right setup. I think it will make a killer street car but not an all out drag car. Like slowhawk said, in about a week we will see what this kit can do compared to my ati d1 kit.
Buncha naysayers. You may be right... but Harlan... your shouldnt be concerned if someone cuts their T-Top well...your engine compartment, and car for that matter has a few changes 
Also...if the pipes crack...build a hanger...theres a fix for everything. I hope I am not proved wrong when I give my set-up a shot. Sitting next to me are some T60 76mm twins.. and I intend on getting more than 700 rw... keep in mind the motor is all done , the IC is in ETC. This also is n ot a 1/4 car,,,just a fun street car. I would NOT think rear mounts would be the fastest way down the track if your comparing them to the standards that are out there... But fun none the less.

Don't give up on STS so quickly Call Rick Squires @ STS 866-WE-TURBO
He's building a drag car with a single turbo that will put down 900 hp+.
He's also got pictures that he took last weekend of 6 second single turbo Camaros with intercooling piping going all the way back to the back seat and back up to engine.
All of the naysayers don't own STS systems. Call the expert.

Call the experts..lol. No, STS needs to call some experts . Intercooler piping has nothing to do with an STS system. Heat loss from exhaust pipe length is the problem. You can put a intercooler anywhere in the system you want, that doesn't effect turbo output and efficiency....lol. Some of you guys need to own/test a few turbo cars...hehe.

I think Rick knows what he is doing...if he says hes gonna have a STS car that will put down 900+ horsepower i believe him. Everything he has said so far is true...the kit works plain and simple. There will always be ways to get around some of the negative issues with this kit...its new...give it some time and STS or turbo fanactics like the ones on this board will find ways to make it better. Every single product that ever came out no matter what it is, car related or not always gets improved. I say just give it some time. Thats just my .02 cents

I would have to agree that it is a new kit and everyone is bashing it. It not really a craze I had my STS on 6 months ago. It just an affordable way to get some decent horsepower. But I have to say that it great for the street but I would't use it for a pure drag car. Nothing runs at the track like a bottle fed car. Go with the N20 and some strong pistons a rods.

Hell, my T-top well is gone to make room for the chute tether, wheelie bars, dry sump tank, etc, etc It is a racecar after all 
Question was if an STS type kit for a track car looking to push 20 psi was a good idea. No it's not
A single that size, mid frame 88 ish, just ain't practical hanging where the muffler is. But, you might not need wheelie bars just casters on the turbo People can argue all they want, but turbos use HEAT energy and flow to spin the turbine wheel. The closer to the port you can get the turbo, the better off you'll be.
If you want a turbo drag car, don't get an STS. If you want a cheap drag car, go nitrous. If you want a cheap turbo on the street, go STS. If you want a fast turbo drag car, get a custom FRONT MOUNT turbo kit
It'd love to see the rear mount 900+ HP car
I was waiting for Harlan to say that Rick has a lane.
For a drag car I think the TTi race kit is a kit that is available now, and it makes good power. I'm waiting to see the PTK LS1 kit, I'm sure that will be a pretty sharp kit too.

What's the average ammount of boost that a stock LS1 can handle? How much can heads reduce compression?
