3.4 whipple race gas max boost

[Garrett114]

I just put some headers and lost 2# of boost the car is just a race car and only sees race gas what would be the most boost to run on a stock bottom using Q16 C16 r MS109

I know it's an opinion but I would like some from people that have pushed the limits of these motors

off topic but what kinda numbers did ur car make before the headers and what psi etc.

 

[Parts-is-Parts]

30psi

I have a stock long block 3.85 pully and before headers I made 20.5# of boost and 611rwhp through an open converter

Why's does 20psi on a 3.8 seem wrong

^ 20.5 psi is about right. I'm running a 4" and I'm seeing around 18.

Why does those psi vs hp numbers seem low... real low. That car should be atleast near 640-660hp at 20psi on race, I think its time to find a new tuner because your not pushing no cobra motor at 611hp. Thats some daily driven power right there
