My Ride: G-Power Z4M, VF Z4
No dyno, and no intercooler. I'm throwing around options right now to get more power. The added boost has been great though!

VF used to claim 330 hp. I've seen this kit listed as "310 hp" recently. I'd side with 310 hp, based on some quick math.

225 hp * (6 + 14.7) / 14.7 = 317 hp

Then subtract some for parasitic losses and supercharger (in)efficiencies. 310 hp is reasonable.
