Last "your tax payer dollars at work" department: Military jets in afterburner typically burn 5-7 times more fuel than they do at normal maximum power.
The built racing engines can burn anywhere from 350 GPH (Merlin) to 550 GPH (R-4360).
FWIW, the last conversation I had with a P-51 owner included the phrase "$1,500 per hour to operate." That figures in maintenance, insurance, and such. Not a cheap hobby, that's for sure.
Hey Lornce; the offer still stands. You get yourself down here and we'll go to the Air Races in Reno. I gots me a spare Airhead for you to ride.
