E85

What's the pros and cons? Im thinking of going to it. What gains should I see? Other than bigger injectors and other hardware needed? Current set up is basic, lethal off road H, no resonators and a tune.

Lost fuel economy for around 10rwhp gain on an na car but no need to worry about detonation during hot months or at the track as long as the tune isn't too aggressive.

if ur not boosted its a waste of time. u will gain 10hp with bolt on so not worth it to me.

Wow, I thought the hp gains was more than that.

If you are running high boost it can be worth 50-100 rwhp. If N/A its not worth shit.

I'd never use it just because of the lack of distribution infrastructure. I don't think there's one E85 station anywhere near me.

Pros: Burns cooler, contains higher octane, lowers risk of detonation you can be more aggressive with a boosted application.

Cons: Not all stations carry E-85, the fuel must be tested if bought from a pump to ensure that it is 85% or better (running lower than E-85 can cause major damage), Requires ~33% more fuel and fuel system (Injectors, Pumps, Lines).

For a N/A application, imho its really not worth it. However down the road on a boosted application, the gains and safety aspect are phenomenal.

A lot of guys run on E70 with their E85 tune. I think I read I read you would need to drop to E60 or less to be an issue octane wise. Depending on the tune, running richer on the plugs would probably be a bigger issue.

I have been getting E70 to e75 and all good here

Definitely jealous of those who have access to it. Some of us are stuck with marginal quality 91 pump and that's it.
