thing with a turbo tho it determines the rpm range. If it starts getting too much BPR then it will choke up and cut your rpm range greatly.


but to give you an idea on what you want to hear a Pt88 on a 370 should shift around 6800 rpms. Thats saying your have no restrictions, properly sized charge pipes, good size downpipe, free flowing exhaust. a cam to support the power range
