Yeah on the HP, you may go up to 20 PSI.

How much is the pump turned up? Is it a 91 or 91.5? 91 non/ic bigger injectors, 91.5 ic smaller injectors, which makes for a big difference in the free power mods. With mine having a BHAF, fuel pin, 4" turbo back, fuel screw all the way in = 25psi of boost, before 4" it was 28psi.

I can hit 24 actually when my injector pump isn't leaking everywhere!

My 93 VE used to hit 42. My 90 with a 5 speed hit 32 with pump turned up, exhaust, intake, turned fuel pin. and that's about it. My p-pump only makes 35 but has more topend.

boost is just restriction of the airflow into the engine.

You forgot to mention the 93 had aftermarket injectors. I think he is more or less wondering what similar setups produce for boost.

Yeah, but that P-Pump is putting out more fuel at top end Josh, he's looking for info on the VE setup.
