spool up is superb, and sounds awesome into the bargain. Could hear it winding up from the car behind
plenty more in there turbo wise, power was limited by fuel pump, injectors and head/cams
Thats good going! I have a 2.0L zetec pushing high 400's with a gen 1 gtx3071r with same boost pressure, I had thought about upgrading to the gen2 GTX but might look at going the G25/660 route.
Have you got any data from it through the gears, when its spooling vs RPM, EGT's?
