pump gas all the way! except for a couple days a year when i feel like turning it up. but ran 10-12lbs all year last year at 6-8k feet on pump gas. the year before i ran 14lbs on straight race gas and i will be the first to admit that i wasted a lot of money for nothing

M8:2871:Twisted RG
9-11K, 91oct with one gallon of 112, 8lbs no problem....some are at 10lbs and doing fine
7-11K, straight 112, 13-16 no problem....anything about 16 hits the knock sensor
Race Gas is alredy a big enough pain to store/buy....propane can only be a bigger PITA....i usually mix fuel/oil for a projected two weeks, could be 20 gallons, could be a barrel, whatever it is, its staged in the trailer and ready to go

3 gal race and the rest pump gas non-ethanol 91 octane. 9-11 psi boost. Runs WAY better than straight race gas at 14 psi. Just like Kinzer...i wasted ALOT of money until i figured this out! Argh!! Probably could run straight PG 91 octane, but just throw the 3 gal RG in there for "insurance"....since i had quite a bit left over from the barrels i bought before. Finally used it up so now will try the straight non-ethanol premium.
20-25% 110 with 91
running 9-15psi
10,500+ feet
1600 miles no problems.

Not when you have to drive a while to get it, I can get propane 2 blocks from my house... I also am getting a larger tank to bring with me so I can just fill it periodically then fill my sled whenever... 1 full tank in the sled and 2-3 more in the truck. Also, I can get propane almost anywhere near me at gas stations, and there open 7 days a week.. and sell propane during all normal hours of the day. Im not saying its nearly as nice as 91.. but it inst to bad if your used to it/plan for it. and the price... If the race gas your getting is $7.50 a gallon(which seems about right for drums right now) I will save $255 per drum of fuel equiv... For those kinda savings I will deal with the possible inconvininces.
sorry for the hijack.. just like to talk.. its summer.

MCX Nytro 15lbs boost most days, sometimes crank it up.
i run 50/50 blend of pump premium either Shell 92 or Chevron 94 and 100/110LL av gas. Usually heavy on the av gas, just to be safe. I would run straigh av, but the pump gas has better lubricating properties and lower flash point gives a little better burn. Seems to run seemless on that mixture. Got a little burbly at the end of last year, but I predict O2 sensor packing it in, or I had some moisture in the fuel.
