Camshaft choice for STS
Camshaft choice for STS I am about to start installing a STS rear mount turbo system on my 04 GTO. Following advice on this board I have the ls1 hotcam which I really love the idle with its 112 lsa. But now that I am going with the forced induction I was wondering if the overlap of the cam would be a problem?

BTW: I'm only running 5PSI of boost.

How much gain do you really see by changing cams with the STS? Would it not be easier to just turn up the boost a little more. Now if you were building a low compressions engine, then I would see the benefit of a turbo cam.
it all depends on what your shooting for. You could go cam and low boost to make say 500 hp and have your power band shifted around/possibly better spooling. Or just crank it up to 8psi. I think once a nice set of low compression heads are on (LQ9s) then a cam would complement the whole thing nicely. For a milder cam choice maybe a 224/230 on 115

With the LT's and boost unfriendly cam I'm still putting down over 426RWHP and 438RWTQ (SAE uncorrected numbers w/ temp 80 degrees F and humidity over 90%). There's more power to be had....once I get the fuel tuning issues all sorted out.

i dont know who you've been talking to but the LT headers are not a problem on the STS. for the record an STS car with LT headers and 3inch exhaust with 5 psi is actually flowing more air than a stock system. boost is a measurement of back pressure if you have less back pressure you will show less boost but get the same amount of air , make sense?? it didnt to me at first but i finally got it through my head.
I have a sts kit and I am getting the 317 castings with the ls6 springs and a gt2-3 cam. I was told that this cam would make better power then the gt-7. I only have the t-60 turbo right now with mid lenths and a ls6 intake. I have 60lbs injectors and a racetronix fuel setup and a frontmount... I am planing on turn the boost up to 7-8lbs when i put all of this on. what do you guys think of this set up??
Sorry to hijack, but for the sake of reducing number of redundant posts:
how will 215.5/232.4, 0.599/0.578, 116.8LSA with LT's with the STS? I have some $$$ coming my way soon, and I'm seriously lookin at this System.

i know because i actually have an STS system with LT headers, unlike yourself - PROCHARGER!!!!
