What are the pros and cons from going from a 93 octane tune to a E-85 tune?
E-85 tune vs 93 octane tune
- Thread starter BLK2012GT
- Start date
more timing equals more power. just make sure your fueling is squared away.

Without getting to in depth. More power, cooler burning, higher octane, no knock, and cheaper than 93 octane. Just need a tuner who can tune it and a fuel system capable of supporting it.
^^^ What he said but a very noticeable drop in fuel mileage.
Also tends cleans off carbon deposits 
there are so many places out by me that has E85.... i want it so bad but if i were to dirve 30 miles out i might be SOL
I know my buddy with a 2012 auto GT with a 2.9 whipple and E85 said he gets over 20mph on the highway still.
i picked up .6 going to e85. and that was on a car already going 9.9's.....
20mph? Dang that's movin out....
I've been 30mph...sometimes I get crazy like that
On topic, e85 is awesome, even NA it might get you some benefits from being less det prone. If you live near it I'd run it, just get a gas tune and keep the sct in the car in case you ever need it.
I'm sure the intake tract stays pretty clean on E85 with these engines. My last pushrod motor was on corn, under the throttle body the plenum floor looked like it had a brown sugar coating after a while. The pistons carboned up about the same as on gasoline.
Can anyone answer how much the stock fuel system can hold if you are tuned to support e85?
As far as I remember, was it 60-80% more fuel capacity required over 91 octane?

Great, are you able to answer my questions regarding how far you can push the stock fuel system while using e85?
Stock pump is fine for all-motor E85.
BAP + stock pump has been pushed to nearly 700RWHP on E85.
Stock injectors will NOT support E85 even on a stock motor. They're simply too small.
47lb injectors or ID's are required before I will do an E85 tune.
12-13hp gained on the dyno, .1-.15 ET and 1-1.5MPH in the 1/4.
The main benefit is the high octane + the cooling effect of the fuel. We can go very aggressive with the tune.

I ran E85 on stock injectors and fuel system with a certain shops tune, the car ran damn good. I decided to have Shaun @ AED do my tunes, and he required that I step up to 47's so I did.. car ran like a bat our of hell with his E85 tune. AED FTW its worth every penny and great support!
what kind of #'s did it lay down? What times are you running at the track?
