Henry Schmidt felt the 3.0 i had at 8.5:1 at 9lbs of boost would of made close to 350hp, i wonder how he came to that theory....
I never had it Dyno'ed but i can tell you a Kennedy Stage 2 clutch and pressure plate couldn't hold it.

I am still running basically a SC 3.0 engine with the only modification done to it is the
930 Euro intake,intercooler, 930 oil pump, and 97mm turbo piston and cylinders with the wrist pin bushing modification for stroke using the 3.0 SC rods, twin plugged, boosting to 1bar via a K27-7200.

Sorry, off topic but I notice you are running a Decel valve. How is that working for you, and did you try it without?
