what is you rev limit set to sam? I am looking at some better valve springs for the 93 I am building. They should be good for 8750....they have a good bottom end...as good as a 4age and they will run 9500 with careful building.
Yep I know it will run out of puff up there but could at least run across the line in 4th
Rev limit currently set to 8200, My springs are from RPW... cant remember the brand...
Current Turbo's compressor map is good for 28psi all the way to 9000rpm... but yeah I did hit the limiter in 4th on the first run for the night
