You could upgrade your DP to a true 3" as the 2.5" is definately a restriction with the 2.5" DP. A 3" system might give you the gains you are looking for with out changing the DP too.
What sort of HP are you currently making at 7.5 psi?

I understand that out of the turbo gas still wants to continue to expand a bit, thus the pipe that exits the turbo side will always be 2.5...but will instantly go to 3" out of the turbo, THEN it stays 3" the rest of the way out right.
You said upgrade the DP to 3" from my current 2.5....that makes sense
a 3" system might give me the gains im looking for with out chaing the DP too???
You figure just bolting a bigger pipe 3" to the 2.5 DP? That means the gas would have to still be expanding at the end of the DP.... do you think that'd be the case? I'd imagine it'd be cooling by that time.
7.5psi is making 300whp.

I think you could run at LEAST 15psi on stock compression with race gas considering I ran 10psi no problem on stock compression with 93 octane.
