I just was curious about it. Since I didnt know much about it I wanted to hear some more educated truth's about converting and whether or not it is worth it.

Not worth it in an NA street motor. Forced induction, N20 or even a high compression NA application would greatly benefit from it. Its basically pump race fuel.

Not a huge fan of e85. A quality race fuel makes more power and is much more consistent. All the Evo and Sti ricers think that they are hot shit for running itComment

There is a reason there is a push for E85 in heads up classes that only allow Gasoline...Originally posted by ThreeHonks View Post
Who wants to pay $8 a gallon for fuel when you can make damn near the same power on a more readily available fuel that costs $3 a gallon...
I'm not saying that E85 is better than gasoline but you cant discount its advantages in a street car.Last edited by c0ncEpT; November 16th, 2011, 08:33 PM.

Really the only thing I dislike is that you have to burn it at like (7.5:1-8.5-:1) air fuel ratio. It just gets burned like its going out of style especially in a boosted car. Just impossible to get any milage out of it.99ws6 - Huron Speed Turbo - PT67

Consistency is the biggest issue. If you are serious about running E85 you'll want to buy it 55 gallons @ a time or use a computer that is "flex fuel" aware.
My uncle runs it in his so called race car - and I just have to laugh at him. He buys it 10 gallons at a time, doesn't have a tester or wideband and is always having to change the jets in his carb, trying to get the car to run consistent.2000 Formula

That scares me too especially under high boost. The octane can vary quite a bit I would hate to get a low batch on a high boost run.99ws6 - Huron Speed Turbo - PT67

Cheap, fast, reliable. Pick 2. If you spend thousands on a nice engine/turbo setup and don't want to run race fuel due to the price, you deserve to have your shit blow up or just be slow.Originally posted by c0ncEpT View Post
I can justify it for a bolt on evo or something but nothing making some type of serious powerComment

Just bumped into this.
Near the bottom they mention E85 wanting plugs three steps colder

seems crazy to run a 8 on a stockish motor with E85.Doing less with more

Just passing info along, but your probably right, and e85 is probably not worth it anyway on a stock motor.
For those not stock though....
Doesnt anybody know the output of our coils?
I was reading on yellowbullet from a guy making 1200/1300hp N/A on E85/E98 that when he switched to E85/E98, he had to upgrade his ignition system, for it to support itself...Comment

Just noticed this post and figured I'd chime in since I'm running E85 in my Firebird. I agree that it's not worth the hassle to switch unless you have a good reason to do so. For me, I run a carburated 13.8-1 comp. NA smallblock on the street. The change for me was strictly for economy reasons. Even if I do use 30% more fuel, that is still less than half the price of the race fuel that I would otherwise have to use. I have seen absolutely no batch issue problems. I have had ZERO tuning problems after at least 20 fillups. But I only run my car in the summer. The batch problem comes when the weather gets cold any they switch the mix from E85% to E70%.
The alcohol also works great to keep the car cool, and against detonation. After a full summer of driving and racing the engine oil and plugs still look like the day that I put them in. Completely spotless. Tuning can be a ***** because the plugs stay so clean that it is almost impossible to read anything on them. An Inovate wide band was a big help in carb tuning.
For me it's been great!Comment
