Hallo
Planing to buy an ati p1-sc kit without intercooler and run it with 6 psi pullys. Dont think i will se more than 4-5 psi beacuse my engine flows better then a stock one (se sig). My question is, will my engine suffer more than a stock one on 6 psi pullys? or would the lower pressure reduce the heat on incoming air so it will be safer from detonation.
Do you think i will se an extra 75 rwhp on this mod? (now 330-350 rwhp)
And i know that an intercooler would be great, but im not gona buy that now, maybe when i change pistongs and lower the comp.

thanks

 

Actually it would probablly "suffer" less than a completely stock motor . It seems that you have a stock short block, but with that cam you should be bleeding off some cylinder pressure. My car had 6psi on it for about 10K miles (completely stock). It should work. I think the blowers efficency may be increased slightly as well but that is probabally negligable.
