Question, would i be limited on boost as far as valvesprings go with stock valvesprings on an 01 head? Where would i be limited at powerwise?

 

Over 25 psi, you should get valve springs...

 

youll also start blowing intake gaskets above that psi too

 

Sorta OT but what do you do for intake gaskets at that PSI? Do you just keep replacing?

 

so 20 psi would be fine? If i can get 600whp i will be happy, it will benifit me moneywise too to keep my 01 heads stock and if/when i get bored of 600whp i will build 03 heads with titanium retainers stiff springs oversized valves with a valve job... pretty much like yours except with turbo cams.

 

20 psi will be fine.

And in regards to the intake gasket question, I haven't had a problem and haven't HEARD of them going out.

 

nah your plently good for a SAFE tune till 23!! (it also alot depends on your tuner and what he thinks your car should do)....but when you start hittin 30's your gonna start blowing that out....couple of ppl have done that around here just being ignorant!!

 

Nah im not gonna go above 20 probably, i'll talk to my tuner about it, i've not had my car on the road for so long i just wanna cut all unecessary costs while still building a solid car, i think i can see close to if not exceeding 600whp with 20psi.

I think ima start a buld thread soon. For the longest time i've not had enough work to pay for this, or the money had to go elsewear unexpectly and now im working 10+ hour days and don't have time to build my car lol. I think next week im back to 8 hour days so should be able to get things rolling.
