[QUOTE="rmc_olderthandirt, post: 1329527, member: 68872"] I am a little confused by this. I had always thought that alcohol based fuels had a much higher octane rating than gasoline, which is why it is used for the really top end racing. I suppose that if the refinery was dropping the gasoline portion of the octane because the alcohol was going to bring it back up then you could get into some interesting problems. What I am 99% sure of is that alcohol burns slower and requires more fuel per a given amount of air to produce the optimum mixture. The slower burn rate translates into ignition timing and the mix rate translates into jetting. So, like Rich said, if you were perfect before, you will be running lean and a little retarded with an alcohol mix. Rod [/QUOTE]
