It was a crow cam regind, I have the specs at home. It cost me about $90.00. Crow can also supply the springs

A 2l engine with 1bar boost can produce 30Lbs/min airflow at 6000rpm which =290hp assuming 100%volumetric efficiency, 70% compressor efficiency, 20 degress celcius, sea level,intercooled 80%efficiency. So you would deserve a medal to acheive this..

Its too bad that a standard sohc 4g63 probably only has a volumetric
efficiency around 75% at 6000 rpm.

This begs the question, what would need to be done to bring the SOHC to 100% at 6000rpm?

I have a VR4 head and running 1bar boost make 212kw/295hp at the wheels which must be around 350hp at the flywheel i figure.
Peak power was at 6366rpm.
Head and cams are stock standard.
I think it really depends a lot on your turbo size, as a bigger turbo will flow more air than a smaller one at the same boost which will create more power when tuned right. Maybe on a SOHC it is different but i would think the same would apply.

Good efficiency=Good Figures. The SOHC responds well to porting and we all know what a TC06 with a T3 wheel can do....well all of us on the cruise that is. Make them breathe and they will come!!!
Who has that video footage??
