Hello, I am curious as to what the boost threshold and spool times would be with a 50 trim on a 9:1 motor. My mods are as follows:

Engine:
- .020 9:1 Wiseco pistons
- Eagle H-beam rods
- 2.0L crank

Intake and Exhaust:
- HKS 264/272 cams
- Unorthodox Racing Adj. cam gears
- 2g exhaust manifold tapped for E.G.T. probe
- Forrester intake manifold
- 3" turbo back exhaust with dynamax muffler
- 2.5" o2 housing

Cooling:
- FMIC with 2.5" piping
- 2.5" UICP
- 3" intake pipe
- K&N filter

Drivetrain:
- 1g trans with LSD(FWD)
- ACT 2600 clutch
- Fidanza flywheel

Tuning:
- AFC 2
- Datalogger

Gauges:
- Autometer ultralight E.G.T.
- Autometer ultralight boost

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.
