i have 2010 camaro ss L99 equipped with KB 2.8LC 7 PSI , 1 7/8 ARH and corsa 2.5 + X-pipe and AEM Stage 1 Meth (M1) tuned and gained 460 RWHP

now my questions are :
1- Do i need to change anything in the engine if i wanted to boost it to 10 PSI ?
2- is it true thats my exhuast makes me lose from (1-2) PSI as been told to me by Kenne Bell Staff ?
3- What Cam do you recommend me for my car ?

1) Boost doesn't impact your motor, cylinder pressure does. Don't go over 650whp
2) Yes, headers will decrease boost because they reduce restriction.
3) Lingenfelter GT9

Thanks for answering my questions

about the headers .. what size do you recommend for my car ??

I'd always go with a 2" for forced induction, that's what I went with too.

Your fuel system may also need upgrading, injectors and pump. Don't forget the l99 lifters. I'm on stock pulley from kb and make about 7-8 psi with Stainless works 1 7/8 LTs, solo Mach xl cat back. I'm looking at same things you from ECS. Maybe a blower cam and ls3 conversion to take the worries out.

I would get a different cam than the gt9 of course I would also go custom.

I'll consider it .. Thanks

I could have gone custom but after doing all the research, there isn't anything bad about the GT9 cam. LPE is one of the largest LSX aftermarket companies, so they really do their homework on their can grinds, you really can't beat them.

Gt9 isn't a bad cam there are just better cams for his app and actually yours. I would rather have the gt11 in a street car anyways more power down low and would more than likely be faster all around at the track with a normal street car build. I would just get a vendor to spec a custom one for your needs and wants that's the best way to go since you get exactly what you want if you ask me and more than likely would be easier on springs etc..
