Yeah when you compare 100 octane to e85 the numbers are comparable but where can you pump 100 octane? 91 vs e85 I went from 420 to 440 peak, picked up midrange gains, and moved my peak power 200 RPM earlier. There was still plenty of fuel left in the tune. But it will require upgrades, probably around 480-500 whp, much sooner than on pump gas. E85 is a good option if you plan on just sticking with intake exhaust. There are already some shops working on fuel solutions so I'm sure we'll see more FI cars running e85 over meth. Also 91 locally is $2.90, as opposed to $1.99 for e85. It isn't just "a few cents".

E-85 in the midwest is not consistent at all. best you can hope for is E -70.
People forget it constantly changes from spring to fall to winter, its just not consistent enough to warrant using it, at least here. To get around this and have the piece of mind i use Torco. I pour a 32oz can of Torco in with 10 gallons of 91 pump to create about 100 octane. I order a case of it off ebay for the better deals with free shipping. yeah its not as cheap as E-85 but it is consistent unlike E-85 from the pump.

There are, or were a few places near me that sold 100 octane unleaded fuel at convenience store stations. I live near a fairly big IHRA track so some of the stores close decided to take advantage of the street racers and track guys in the area. I also know that Rockingham Dragway also has both a 100 octane unleaded pump and a 115 leaded racing fuel pump just inside the gate. I would get about 5 gallons of the 100 every time i went there to run my 98 Z28. I would always arrive running on "fumes" so that I would not be diluting the fuel much with the 93 I normally ran. Everywhere that I have bought the 100 from was expensive. About 5.50 to 5.99 per gallon. But it was 100 octane unleaded which is very hard to find. My 98 loved the stuff and I ran my best times with it at Rockingham. |
