I have watched this whole ethanol thing unfold with much interest. Maybe I missed something but I have yet to hear of anyone speaking to the heart of the problem with ethanol regarding open wheel race cars. Its not the fuel - its the cars! Now let me explain that. Mechanical fuel injection and methanol are a good match for each other and that combination has worked great for years, but have you ever seen somebody try to run a gasoline motor with a Hilborn fuel injector? It can be done, for sure, but its a LOT harder to keep a motor happy if its got mechanical F.I. and its on gasoline. The reason for that is that the 'sweet spot' with methanol is much broader that with gas. Methanol is a much 'slower' fuel and as such, you can be a lot farther off on your calibrations and still be in the ballpark. How many times have you guys changed a barrel valve setting or a bypass setting only to have the driver tell you he didn't think it made much difference? With gasoline, you don't get that kind of leeway.
Ethanol lies somewhere in between gas and methanol when it comes to this 'sweet spot' issue. The teams that have had success with ethanol are the ones with the ability to really be right on top of their fuel calibrations, with much more accuracy than they ever needed with methanol.
There is nothing 'wrong' with ethanol as a fuel (other than the fact that it's a really dumb way to make fuel....). I know there are some people reading this that don't want to hear it, but what has happened here is that we've put the cart before the horse. If we had engine management systems on open wheel cars - technology that has only been around for, say, the past 20 YEARS or so - instead of a fuel system from the 1950's, there would be absolutely no problem with running open wheel cars on ethanol, if that is what 16th Street decided we need to do.
Right now, today, I can run ethanol just fine in one of my ECOtec motors, and I can run methanol in the same motor without any problem at all. Could also run gasoline in it.
I'm not trying to sell anybody on anything (gave that up a while ago). I spent all of my gear-head life working on mechanical fuel injection - I honestly don't know how to work on a carburetor because I never have. I never dreamed I'd be going down this electronic path until I got hooked up with the guys at GM Racing, and they showed me what the possibilities are. I don't have a thing against mechanical F.I., I'm just pointing out that this sport has got some decisions to make, and those decisions have been put off for too long now.
