Anyone running E85 regularly?

[JLaw]

I heard that you can get it at the pump in some countries, whos using it in there high po cal lookers- is it better than 99ron? Should we be looking into adapting our cars to run it? I'd like to hear the views of those that use it.

Cheers John.

It has both pros and cons.

Pros:
Cools better
More octane
Less sensitive to weather changes - less jetting changes.

Cons:
Takes forever to get warm
Less energy
Harms rubber
You need more fuel - the driving range is shorter.
People think you have some kind of miracle fuel , they think you're cheating!

According to JPM there is 4-5 hp to gain on a 250 hp N/A engine with the same set up. To get more you need to raise the compression a lot and that is tough for your rod bearings. I ran E-85 last year and this year I am going to use pump gas, at least for a start. It is easy to switch between the fuels as the only things you need to change is the fuel jets.
On turbo cars it is a different thing though, as you can turn up the boost a lot with E85.
