opinion and assistance

Just curious at what PSI the evo is running at. I have a turbo'd 2.4 and looking at P&P head, new cam, and intake manifold, and possibly new pistons. What I would like to know: I figure I can push 10-12psi on these mods alone and roughly figure it would take me to 280-300hp safely? what are most of you evo owners dialling your PSI up to on minimal mods and what numbers are you pushing hp?

Evo IX stock is in the area of 19-20.5

Yeah, we start out at 19.5 (03-04) or 20.3 (05-06) peak in stock form with it tapering to 16-17psi. We typically run 21-22psi (VIIIs) or 22-24psi (IXs) on 93oct but much more on race gas or alky.

This will not translate into what you can run, because that will depend on engine compression, the engine internals, the size/location of your intercooler, octane, tuning, etc.
