New 4g63 record!

Brent runs 75+, so 54 is medium boost.

I think that is the next turbo we run on Kyles car. 71mm to a 74.x mm should be a pretty good jump. The 4202 seems to make almost unreal power numbers based on airflow numbers.

Not on gas though. That's the highest boost I've ever heard of on gas.
