Been good to me and a couple mates.

I use a custom 850 holley from eric at horsepower innovations, but the new quick fuel ones are pretty good as well

Anybody got a baseline tune for e85 carb? It has i think 89 jets in front with pv and 91 in back. I can post build sheet, but jets were changed. Carb came of 434 stroker running little slower than my 6.0

What are you going to set your fuel pressure at when running on e85?

Thanks,
Matt

i run 6.5 psi, float in the middle of sight glass. i did upgrade my needle and seat to titanium 150thou (methanol size) as rear bowl dropped a little on the dyno

Mine is on 6.5 right now. It has some screwed up staggered idle bleeds in it...Jmark isnt sure whats up with that.

Thanks for the replies. I wasn't sure if you were supposed to up the pressure any when going from regular fuel to e85.

According to what I seen on marksullense85carburetors.com Nope, he likes 6.5 as a baseline. He is probably going to be building mine if I like the corn.
