FWIW, one of the local guys runs these on his e90 (FBO, e60 mix I believe) and traps 100 to 101 mph in the 1/8 mile. Can't remember what time he runs but want to say in the very low sevens - that's on NT05Rs.
Damn I hit 17psi with stock turbos now on 93. Dropping my car off to have my pure stage1s put in this Friday.
