Not doubting your experience, but Matthew Brusstar at the EPA stated in this article http://www.epa.gov/OMS/presentations/gni-mjb-051303.pdf that ethanol has a higher laminar flame speed than gasoline. See the chart on page 9. I saw a disagreement between Pro Systems and a Sullens guy and I know the facts. Here are the facts. EPA agrees with Pro Systems findings and COMPLETELY disagrees with Sullens.
PDF no longer available? :)

Back from the dead!!!!!!!!!!!!!!!

Anybody REALLY know the top CR limit is for pump E85?

I have read like 17.5 to 1 or so in Turbo race engine configurations.

I do figure that at say, 13.5 to 14 to 1 CR, it would power great high compressioned street engines as long as I could get it locally here in central MO. (Columbia, MO)...

We ran 14.2 to one regularly with no ill effects. I dyno'ed my 15.5 to 1 SB2.2 on an inertia dyno with no problem, just made less power than race gas.
