Hells yeah...love it. To get 450 whp with vt2-500 I need to add the smaller pulley that Roman is including, which brings boost to 8psi. I also need Euro spec headers and 93 octane or higher. The 450 whp is without water/meth and would only be achieved in 60-70F temp sea level weather. Your right, 450 whp in the Z4M will be a serious ride
I still can't believe the car made 410whp in 105F heat at 1300 elevation!! that is insane
I may increase the boost to 9 or 10psi with water/meth and fail safes in place. That will be a calculated move and will be done carefully. I would like to get the car to 500 whp, but I need to do some homework first
I just want to enjoy the car as it is for awhile and then make my decision to ADD
