hey guys, they are 18x7.5 45mm and boy they piss me off! as for the dyno, it was a dynojet, and he did a few pulls in 3rd and 4th, but he let off at 7000 rpm. The redline is like 7200 or 7300 so if he ad kept pushin it might have been a little better but rather safe than broken!!! Plus as csmith said I really don't have anything done to the motor yet. My turbo setup takes care of intake, FI, and headers back to the cat, so I figured why buy twice. I am told thought that the j32 will come to life after boost and I am hoping for 350ish whp daily driver, but we'll see in a couple months!
