I've got twin HP Walbro 255's, 720cc primaries and 450cc secondaries. I should be ready for E85 next year. That will be replacing my 100 octane unleaded I've been using for years. I've been hearing great things about it.

What managment system will you use, if you don't mind?

Couldn't give you a power number with those injectors, but I can let you know that either E85 or leaded 110 ate up one of our O2 sesnors. However, Santa has been running E85 on a close to stock fuel system with no adverse affects as of yet...

The E85 ate up O2 sensors? Crap, that is one of the big reasons I wanted to go to it. That and it should be more consistent than the 111 from Bobby & Steves. Are you using the Bosch WBO2 sensors?

What about cars meant to use e85. My dad's van is set up for it, and he hasn't had any issues I think. I think it threw a CEL but it went away? I'll ask him, but he uses e85 all the time. It smells like dinner when he drives off.

E85 will not eat o2 sensors. It was more than likely the leaded 110. Alchohol(e85) is not bad for 02 sensors, lead is.

Use the E85, dont worry about anything except for the possibility of corroding the aluminum pieces in your fuel system. Even that I wouldnt worry about it to much with how much you drive your car.

1.79 for 105 octane, hell yeah.:)

Speaking of the stuff at bobby and steve's gas, I get less knock on my 60/40 mix than I do straight 111 race gas at bobby and steve's. That doesn't make sense since my 60/40 mix should be around 100 octane or else bobby and steve's race gas is shit.

Octane rating aside, is it just the alchohol? Cooler burn?

I havent researched it enough to know the true answer.

Well, This thread has been pretty helpful so far, but, I think my fuel rail might be aluminum, and I will get that coated and possibly my intake manifold, but the head gets to suffer the wrath of corn booze.

BTW, does anyone know what kind of long term damage an aluminum piston will suffer? Maybe none since the fuel is burning in there?

I drove all summer and late last year on e85 mix and recently replaced my head gasket. Wisecos were fine, head did not look to be any worse for the wear and the fuel rail is fine.

It is my understanding that ethanol needs water to be present to really become corrosive to aluminum. Either way 7,000+ miles shows no detectable wear. I would be more concerned with the rubber fuel lines before the fuel rail.
