Compression should definitely be high (or more boost and timing) to take advantage of the octane.

At least for the metal parts. This may be what the synthetic oil is for in that guys site, he adds it to the E85 perhaps? Older rubber lines on older vehicles would prob still need changing. There is a big fight going on in aviation with AGE85 here is the pro-age85 site http://www.age85.org/ They say that the compression ratio is INCREASED to gain max benefit. (aircraft engines generally have low compression to start off with) Pilots have been discussing some big issues/unknowns with AGE85/Ethanol avgas.... The idea doesn't seem popular, at all. The FAA cites numerous reasons that alcohol and airplanes do not mix. Alcohol: Adversely affects the volatility of auto gasoline, which could cause vapor lock. Is corrosive and not compatible with the rubber seals and other materials used in aircraft, which could lead to fuel system deterioration and malfunction. Is subject to phase separation, which happens when the fuel is cooled as an aircraft climbs to higher altitudes. When the alcohol separates from the gasoline, it may carry water that has been held in solution and that cannot be handled by the sediment bowl. Reduces the energy content of the fuel. Methanol has approximately 55 percent of the energy content of gasoline, ethanol 73 percent. More alcohol equals reduced range.

The only changes are an upgraded fuel pump, larger injectors and a re-tune. You will need 30% more E85 by volume than with gasoline. Not a single one of these E85 EVOs has had any corrosion issues. All are running stock fuel lines, stock tank, stock fuel rail, etc. There is a special forum section on EvolutionM.net for Special Fuels - lots of E85 info. Here is the link: http://forums.evolutionm.net/forumdisplay.php?f=225 Jim in Tucson In a message dated 5/6/2008 9:44:05 A.M. US Mountain Standard Time, [EMAIL PROTECTED] writes: So, after reading the archives, it looks like the question was never actually answered (but boy did it create a long list of people talking about the USA's energy policy!). There was some hand waving about it not being just as simple as putting E85 in your tank and retuning, but no concrete examples of things tried, problems encountered, solutions created, etc. I'm looking to avoid the whole discussion of whether or not this is a good energy policy and mainly wondering if it can be done on a hobby level. Replacing fuel lines, the pump, and injectors seems like an easy task and gives me an excuse to continue to tinker with the Miata. I had considered doing an AC electric motor conversion to the Miata, but that's going to be far more work and far more expensive (like $20k, at least, to do it right). So, has anyone else given any thought to E85 in their Link Miata, and if so, how did it go? Thanks!
