VF22 on a EJ25

i understand that the VF22 is more of a top end performer, and i read on a few threads that it starts to spool up at about 3300rpm etc... but thats on a EJ20 block.
What about on a EJ25? im guessing it will start to spool up earlier? correct?
and does anyone know roughly how much whp it makes on a EJ25, on about 14 psi?.... with necessary mods ofcourse...
cheers

it's really hard to estimate that. It's based on your car, your dyno, your tune, and a million other factors from altitude to fuel type. You're going to have to be a hell of a lot more specific unless you want some meaningless number pulled out of the air.

It'll spool 214 rpms earlier and make 285.17 whp... If you think I pulled those out of my ass ass and they're totally inaccurate, you're right.

It would probably put up #'s close to VF34's and VF39's with slightly more hp and turbo lag.The VF22 compressor wheel/turbine wheel is not really any bigger than the VF34/39's it just uses a bigger turbine housing(P20).
