An 03/04 engine with 12psi will make at least 50rw less than a flat top pistoned engine. I know as I've had experience with both.
And to run that boost level on a flat top piston you need race gas
An 03/04 on race gas can be boosted to 22+ psi FTW :banana:
One more time: if you want to make max hp on an FI motor you go low compression and boost the snot out of it.
If you wanna make max hp on a high compression FI motor you put low compression pistons in it :-D
I know this is painful for some people to accept :nonono:
