    Well since a stock turbo makes 200/205 at 6.5psi. I would guess add a couple hp for higher compression and a couple for the extra 1.5 psi. I'd say assuming everything is right with the car you will have 215-220. Huge gain from your current 160ish I guess.

      on a new motor (rebuilt) 9:1 compression, with e-fan (was turned "on" during the dyno run), no exhaust (open downpipe), Cone Filter, and stock charge pipe plumbing on stock boost I made 214RWHP and 243RWTQ...

      just to give u an idea...
