Due to the continued rising cost of fuel (TORCO $6.69) and I have a street strip car I have been thanking of making a change to E85 and I would like to hear some PROS & CONS experiences from those of you that have tried it.
I had the same idea, but mine runs fine on 87 octane, I just got gas for the nova yesterday and next to the pump was turbo blue for over $6 and was thinking next time i rebuild im using e85, so my opinion on it is to convert it over, e85 is 105 octane but i here you burn it up faster, i would do it for a 1/3 of the price still, i think your hoses have to be replaced too, im sure someone will chime in with a whole set up. Quikfuel has a e85 carb and there are metering plate kits for holleys, I think eddy's too, shoudn't be to painful to change over..
The pros is, if we are talking on a carbed american V8 you usually se a torque increase of 4-7% in the hole rev range without doing anything but jet it up for the extra fuel. That means 4-7 % more usable horsepower over the hole rev range. Also you can run really high comp ratios, i myself have run 13,5:1 on a road race SBC without problems. And you can get away with much higher ratios depending on the dynamic comp ratio and application.
The cons is you need to modify the carb for E85 or buy a E85 carb.
Larger fuel tank , fuel pump, lines. And sometimes its harder to start from cold.
I think E85 is a great fuel and run it on all my cars. And i have never used anything but ordinary quality fuel lines/hose.
I've been using the stuff for 3 or 4 years now and love it. The only complaint I have is the availibility. It is sold right here in town which is great, but when I go out of town it's a little harder to find. I am running 496, 11.5 comp, roller cam, alum heads, and tunnel ram. Best run so far is a [email protected] I know there is more in it, still trying to work the bugs out of the new motor.
