[QUOTE="ripnbst, post: 2492739, member: 16136"] Heres the deal with that. As well as the "Are you saying E-85 is only 85% as efficient?" Equal volumes of Ethanol and gasoline, ethanol doesn't produce as much energy as gasoline, fact. To net the same power from an engine with ethanol as gasoline you need to inject more ethanol into the cylinder than you would gasoline. Now for the racers, ethanol is more tolerant of heat and pressure, meaning it won't pre-ignite (detonate) like gasoline will which means with proper tuning you can actually get more power out of the same motor using ethanol, because you can push the limits further. You just need to use more ethanol to do it. Dont quote me on this number but I think it's ~15% more ethanol. What sucks is that by the time we're at 40 mpg as standard gasoline will be $6.00/gal. It will be better for mother nature but your pocket book wont notice any difference. [/QUOTE]
