What is needed is taking advantage of the exhaust scavenging effect and have the highest exhaust velocity. Backpressure is not needed, but if you think it is, then that's cool. But I don't really think it is from everything I've learned and read about.
Anyways, has anyone experimented with timing on the cars listed above? Should I advance or retard it from it's base?
