I have had lengthy conversations about this topic with some very repected names. I want this discussion out there though for others to learn from and to give me the ammo to more forward with a very painful decision. I am on 93/meth and a couple of the fast folk say I need to jump to corn liquor to get the most out of my new build. Meth is a high octane fuel source and I am hitting mine with 30 GPH now. Some really smart folk break it down for me why my meth93 combo will never beat majic corn liquor. I need details, science and some good old fashioned reassurance that corn is king.
... and discuss!

 

in for info.... btw just got back form brunswick... the islands were fun! :0

 

Depends on your goals...id say the break even point in terms of power would be around 20psi of boost. With that said I use 93/meth at 25psi. Dont forget you will get terrible gas mileage and tough cold starts with e85. The latter not such a problem in summer but will become one in the fall/winter.

 

With all do respect , are you sure that combo of 93 and meth is not what rattled the guts out of your built engine? That is the very situation I am trying desperately to avoid. Please don't take the first statement wrong, I know there is a lot of pioneering on your part to push those levels.
THANKS for replying.

 

I am in the process of making a complete flex fuel system. I will run E10 all week long and switch to E85 when I go to the track. That is if all works well...

 

If e85 was at most of the pumps around my here I would run it. I'm sticking to 93 until then.

It sucks having a dd that I would only be able to fill up at 5 stations in buffalo.

 

I will also be running 93/meth just because the nearest E85 station is 25min away and im afraid I will stay without gas one day. But I would like to try E85 just to see if there is enough of a difference to make a change.

 

I would run e85 hands down IF there were more stations around me with it. There's only two that I know of and they are both 20+ min away. I know a few guys that made the switch to e85 and never looked back. Even a couple max effort N/A applications

 

5 years ago this answer would have been easy. E85 benefits notwithstanding...it's a toss up now. I've been running a 50% mix for about a year and a half now and I'll have to admit, it certainly gets old. I can still pull down decent mileage, but still not on par with pump gas alone. Considering the increased price and general lack of availability, I am looking at other options..
