The engines in sprint cars on dirt also depend on slowing down with the compression when going into the corners. With all of my racing experience I've found that engines with lots of power are not as easy to handle in the corners as low powered engines. The perfect engine would be an engine with a 3" stroke that would turn from 12 to 15 thousand RPM's and stay together. Did anyone ever try a JAKE brake like the big trucks use instead of using brakes?
