Thanks.
Hank: didn't run the 1/4 mile Yet, ,but sholud run mid to high 12's.
jim W: Yes, cast pistons are used, and they much weaker than forged ones. I told my brother he is pushing the envelope. In fact, he already broke some ring lands, but that was due to a lean mixture (he is stiil pushing the envelope, since this engine produces around 380 hp and 400 fl/lbs of torque!). It's fixed now. Keep away detonation, run on the rich side and hold on for your life (and engine´s life). Ethanol has a much higher octane rating (around 103) than pump gas and promotes a cooler intake charge. 12 injectors are used for beter control AND volume. 6 Ford racing re used when running normally aspirated and more 6 (custom modified Bosch injectors) when under boost.
An alcohol engine has a big apetite, around 30% more than a gasoline engine, so fuel delivery is critical.
