So what happens when 100LL is gone anyway?
ISTR there's only one company that still makes TEL (I think it's in the
UK?) When they decide the cost isn't worth it, what then? Sure, the lower HP Lyc's and Cont's can probably run mogas without issue, but the higher HP turbo'd engines won't be so happy without lead. The FADEC mod being developed by Aerosance might be a solution for some engines by computerized ignition retarding, but that's not a cheap fix. Anyone read anything more about the coming end of avgas? |

We have the power back on a P51 now to 45 inches on takeoff because of the fuel restriction. Any lower and the damn airplane will be taking off at cruise power!! :-) Dudley henriques |

Interesting.. a month or so ago at the Corsairs over Connecticut
weekend at Sikorsky Airport I spoke to the owner of one of the F4Us about just that. With 115/130 being long gone they're limited to 50in on takeoff to keep the engine from making bad sounds. |

It would take special arrangements to get it, but I think it is well over 100 octane. -- Jim in NC |

for sure......it's flammable :-))) Dudley "Morgans" wrote in message ...

A quick google search turned up this: http://www.motorsportsracingfuels.com/RacingFuel.html I also remember some other racing fuels, but they didn't turn up in a quick search. To save you some page flipping I copied some of the numbers. Sunoco racing fuels Name, (R+M)/2, research, motor, color, price 54 gal drum Standard, 110, 115, 105, purple, $281 (probably the old familiar Cam2) Supreme, 112, 114, 110, blue, $335 Maximal, 116, 118, 114, red, $389 Max5, 116, 119, 113, lt red, $443 NOS, 117, 120, 113, lt red, $416 MO2X, 112, 115, 109, green, $424 MX114, 114, 118, 110, yellow, $??? unleaded GT, 100, 105, 95, clear, $308 GT+, 104, 109, 99, lt blue, $314 Now, do you want to put the purple stuff in the airplane at $5.20 a gallon? What about $7.70 a gallon for the NOS? I also wonder what might happen if you mixed the cheaper 100LL with the unleaded GT or GT+. Does the diluted lead content give you an octane boost and if it does, by how much? I won't even start on what the chemical composition of racing fuels might do to gaskets and seals etc. on an airplane engine. Maybe more google searches are in order. |
