After a good talk with the dyno shop who tuned the motor I have decided to go back to avgas. I know I know.... we had a whole thread about it but worst case is I blow up a $500 long block. The motor was tuned for it and it ran on it for 3 seasons before I owned it. The price is MUCH cheaper than race fuel and its unleaded. $11.50/gal for unleaded race fuel or $3.50/gal for unleaded avgas. So if you boil it down:-The motor was set up for avgas-Dont need to spend extra for a water methanol system-Dont need to spend anything to retune and upgrade for E85-And fuel cost goes down Either the water/methanol or the e85 conversion will cost more than $500 without a question. I might have no issues with the avgas for free. Seems like a no brainer to me.
17 LB of boost! Wow what kind of HP you running with that? Who is your tuner and what ignition are you running? I would love to run stright avgas. I can buy it all day long at the Dead Cow Airport in wichita.
what were they thinking!! lol not a good way to sell tickets! lol!!
