s475 on untouch ls1, what to expect with 9psi so just ordered my s475 turbo with 96mm turbine wheel and 1.32 a/r from forced inductions........ thats what they recommended. The car still has stock cam and intake. Like i said long block is untouched. It will be front mounted using manifolds.
60-75 pound injectors
possibly meth injection to be safe..
What should i expected rwhp on 9psi????
Not looking to set any certain number just like to know what to expect.
I have a 6.0 on engine stand for forging future for a backup but wanna run a safe, fun tune on the stock ls till it lets go. Since its already in there lol....
All input is appreciated...
Thanks

Honestly, at 9psi with an S475, I really don't see you being any less than 500rwhp on a t56. There are many people in that range with smaller turbine units pushing closer to 550rwhp at close to 10psi on ls1's. It's all in the tune though, remember that. =)

trust me if you dont do springs , youll be "that guy" making a , "help me figure out why my car wont make any power past 5400 rpm" thread . Dont be that guy.
With that being said, im going to say , 475-480 rwhp

well if im gonna do pushrods and springs i might as well get the cam to lol. That would pick my power up even more..... But i want the weekender to last a while so not wanting to push my luck. And again i could transferr cam over to 6.0 later to so its spend money now or later basically. Any tips for turbo cam??

I wouldn't throw a cam in it just because you're already putting springs and pushrods in it, you only have to pull the valve covers for those. I would, however, put a cam in it because it will help spool and power. Also, it's not going to be any less reliable if you keep the rpm's in check.

Jeez, I missed the springs part, yes... definitely, while you're doing it, toss a good cam in there with pushrods and springs and go for it. You'll be happy with it.
