depends on which hotside but would most likely start to make boost about 2500-2800 and hit full boost about 3800-4100

The turbo I have is a SCM5031. It has a 76 trim turbine wheel.

I've got 9:1 with a ball bearing SCM 5031. I run 25psi on 93 octane with no problems. I hit full boost in the low to mid 3k range.
