Very nice Charlie! E85 really brings in the torque with that extra stroke. How much overlap at .050" lift with that cam?

That is a record for E85 as far as I know. Where do you folks get it out there.

Care to share the air fuel ratio in OL? I have found the ideal ratio, and it is different than what Katech tuned for on the dyno.

Remarkable work!!! Your heads must flow over 400 cfm to achieve those numbers.

Moving from 8.4:1 to 8.64:1 bumped 10 RWHP. Cool deal Charlie.

I think 400 is about the end of the road for under .700 lift.

I love the way E85 brings its own O2 to the party. Race gas from the pump.

Thanks for the info.

Jim, Just so you know, I've been finding E-85 starting at the border in San Diego up to Oceanside along I-5. Numerous stations along the way. Haven't really looked up past San Clemente but I know there are some up that way all the way to LA.. Nick
