That's some really great racing Barnsey!!! I checked out a number of the videos on the link you posted earlier!!! My very first racing job was with one of the IMSA GT teams in the mid-70's, kind of reminds me of the Supercar racing in Australia!!! Big money, but not so crazy that with a bit of proper sponsorship a good racer could compete! Suppose one of those teams would want to hire a crippled up old fabricator for a couple seasons?????

In drag racing, we switch to E-85 about 5 years ago and have actually had fewer engine problems then we did with race gas... Initially we did it because of a sponsorship offer, but later were quite happy that we did... We blend the pump E-85 up to about E-90, our goal is 112 octane so we add E-100 to the E-85 to come up with the 112 octane. Main challenge on the learning curve of using ethanol is reading the plugs---they are very slow to color.... An air fuel ratio monitor solved that issue... We also run an pyrometer in one of the collectors as a final read on what the cylinders are burning at.... Don't think I'd switch back to race fuel even if it were the same price!!! Our E-90 comes out to right at $2.00/gallon, the equivalant octane in racing gas is over $6.00/gallon!!!!
