Second, would E-85 allow me to boost the compression and timing?
I'm fairly certain you could,but since it's being blended with gasoline I'm not certain of the octane rating.
It would be cool if somebody (someone a lot smarter than me) could come up with an easily switchable retrofit that would allow older carbureted engines to switch back and forth between gasoline and E-85...[/QUOTE]
Theres a company called dial-a-jet that some of the racers are using might check them out.
