Many forums need to have mandatory stickies regarding what fuel octane actually means to engine performance.

E85 Very plainly is 85% ethanol and 15% petrol. There is not to my knowledge any significant regulation on the octane rating of the 15% of E85 that is petrol.

According to wikipedia there is also E85 winter blend, which is actually E70 (70% ethanol, 30% gasoline). It makes a note (that I find ironic) that because
Winter E85 (E70) contains more petrol that MPG is much higher than with E85 so for once a winter blend fuel with beter MPG than its non-seasonal counterpart.

Wikipedia also states that E85 is mistakenly though to be 105 octane when it is infact 94-96 octane (R+M/2). It also states that E85's use in racing applications First because of its 94-96 octane rating is higher than most premium pump fuel 91-94 octane; and second because of lower intake charge temps.

I would like to point out that water/meth injection is much cheaper and far more effective than e85.

E85 would be a great performance fuel choice for ethanol purpose built engines with closer 14:1 compression and fuel-injection control systems that have a wider range of pulse widths to inject approximately 34% more fuel than a non e85 engine. E85 has a different stoichiometric ratio than pump petrol.

E85 would not be my first choice for a little bit more pep in an inline4 engine.

Glad to hear you have such good luck in your SRT4. I wonder how awesome that would have gone with 94octane and meth injection.
It's already been proven that E85 is better than pump plus meth on that platform. There is no such thing as 93 or 94 here either. 91 is it. 93 would be a nice DD fuel if it was available and common.

And it's not a little bit more power either.
