STS Turbo
[B]STS Turbo[/B] Okay guys, since you ALL know more about this stuff than I do, I'll post the question.... I've heard a million gear heads tell me boost = bad on the high compression LS1. Then I have a million + 1 salesmen telling me boost = good on the high compression LS1. Can I really run a 5-7 lb turbo on my (stock) 45k+miles LS1 and expect it not to gernade on me? With the 4 grand it's going to cost me for the turbo, I wouldn't be able to do all the rest of the really fancy stuff. ... I just want to beat my boss's Vette, and KILL my friends Cobra. 
Oh yeah, and I'm new to the forrum thing, so I'm still trying to get the profile thing down bad @$$ like you guys have got. Thanks for the help!

do you have stock CR?
if its higher id get it back to stock or lower before boosting (you can do this cheaply by a change of heads and or gaskets.)
next if you worried about affording it, all of us hear know going FI is expensive, it doesnt stop, you will keep on throwing money into your car, there is not stoping.
SO if your going FI go all the way, it isnt worth it unless your power goals are big.
with that said it might be better to get heads, cam, nitrous, clutch or converter.
id say that would give you better results then the STS and be cheaper.

Iagree with the above except the last part. That is totallt subjective. I did the heads/cam/nitrous/huge converter route and it ruins driveability wether people will admit it or not. If you want easy power and have the car feel like it cam from the facotry with tons of power then I say go forced induction wether it be a turbo or blower. You'll save money in the long run and have more HP than you could with heads/cam alone. Nitrous is cool but filling bottle sucks 
I'm just at 5psi, but the car is driven hard all the time. Since I sell the kits, I have to give rides and people obviously want to see how it runs. Doing great so far.
These kits do have more potential than just the stock motor. We are adding a few mods to see how it acts.

but whats done to his bosses vette and how many stock cobras do you see running around?
either one will allow you to go fast as hell depending on how wild of a cam, but the turbo will retain stock driveability and gas mileage.

Running FI on our cars isn't a problem as long as you have stock CR or lower. Basically on a FI car, its all about tuning. You MUST run good fuel in the car at all times also.
I put the blower on my car at 54K miles, I currently have 104K on the stock engine. The car runs great and handles the boost well. I started out with a 4# kit...then upped it to the 6# pulley and now even more(see sig). Its all about your tune. Make sure your A/F ratio ON THE STREET is good. Just because your A/F ratio on the dyno is "12.0" or whatnot, doesn't mean its that on the street(usually on the street it leans out from the dyno). If you can run a wide band O2, do it. That's the only way to tune IMHO.
If you need any help, feel free to post on the board. There are a lot of people here running FI and doing well.

Okay, I've heard the 'tuning' thing several times now, but am still a bit in the dark as to what that means. Are we talking about bigger fuel injectors/pump only, or is there a whole gambit of stuff out there that's going to sneek up on me once I think I'm done. Also, how much does a balance/blueprint cost? Will it really up my redline by a few k? Thanks guys, I never would have been able to sort through all this by myself. LOL Man, I've gotta do something quick too, because my boss is already talking schmack w/ his Z06. I keep telling my friend w/ the Cobra to walk light though, because he's about to wake up that Z28 out there. 
tuning means get your computer retuned, also you need enough pump and injector.
as heads an cam a friend of mine has longtubes, loudmouth, and 218/229-113 cam and a couple of suspension parts, and he has no problems killing vettes (hasnt ran any SC cobras yet) he is on stock heads, also his driveability is good, loud but good.
it all comes down to how much power you want to make. a supercharger might be an easier bolt on route to, running about 6-7psi, but will probably take you up a little more on the power levels of a good heads and cam

Use my parts to make your own kit for under $1000...

I think $4000 for their kit is about double what its worth, imho.

Hmmm.... Hey guys, is this too good to be true? Is it everything I need? How much will it cost for me to get the tubing made, and the thing put into working order? I'm only about 2 hours away, so is there anything I should check for before I go it? That would be BEYOND AWSOME!!! 
Thanks as always.

If I were to lower my compression ratio in order to run more boost, like you were saying (w/ heads or even a gasket), how is that different than running higher compression and lower boost? I guess I'm not understanding the physics behind it. Is running 9.0:1 compression w/ 7lbs of boost faster than running 10.0:1 compression w/ say 6lbs of boost?
Oh well, it doesn't matter now anyway. I just got trumped by my better half. Thanks for all the help though guys.... maybe I'll get lucky, and win the lotto. 
Peace.

You would be fine with stock compression. Like a few others said, tuning is key. But not just tuning, fuel as well.
You can run 5psi on the stock engine with no problems as long as you upgrade the injectors and do a safe tune. I would say if you plan on keeping it at 5psi, you could go with 30lb injectors.
As long as you tune for the right amount of fuel, the stock timing table should be suitable for 5psi. Tuning for more fuel delivery is very easy, but if you have no idea how, then your best bet is to get a professional dyno tune.
Key is to prevent detonation. If you DONT supply enough fuel, you will detonate and eventually have to rebuild engine.
Stock LS1 is good for high HP, just has to be TUNED for it with a good fuel system!
With that, you should make safe 400+RWHP.
Add a methanol kit

Stock for STS The STS turbo kit comes to you for use on a stock vehicle that includes stock tune, injectors, fuel pump etc. now if you are to up it for more power then you will have to upgrade certain parts and poss. lower compression ratio some to allow for the higher boost as has been said in previous posts... But the basic STS kit is for stock applications
Good luck
