What this means is you will need to burn more E-85 than gas, and so will need to look at cost of a gallon of gas verses 1.x gallons of E-85.

Yes, but with my situation (turbo 40 psi) it's cheaper than race gas by far.

I use it on the street for driving around it's not so bad.

This E-85 has got me thinking, is there a benefit to it ? Its cheap, plenty of octane and I would have to re work a couple of carbs.
I was planning on settling down with the 94.2 octane and be done with it. It would be 4.5 gallons of 92 octane mixed with 1/2 gallon of 114 octane but its almost double the cost of the E-85.

Yes, I can see it for you, but was pointing out to Dragncar / Troy that there might not be as much savings as he thinks.

I kind of feel that it might be cheaper for him to buy because the e85 usually is 1.00 or more cheaper than 92. 100 octane is 16.00 a gallon here. idk what it is over there. He will be able to add more timing as well if he needs to .. Plus, the hassle of mixing fuel, I know I wouldn't like to do that all the time myself.
