with a small block hi rpm combo-- if you took the same engine[ obvious jet change ] and ran back to back dyno test with each type fuel, what would you think the difference would be in hp figures? basicly I am curious about the gain or loss that would come from only the fuel change. I know air temp and such will play a big role... just in general what would you expect to see ?
