Not sure but i think Bruce Bohanan's plane "Flyin' Tiger" runs Nitrous Oxide. He has set all kinds of time to climb records.
Wish we could run Nitrous Oxide in a piston jump plane.

the other guy left out an O. I've flown a Soloy 207 quite a bit. It was a great jump plane. Easy to fly and good performance. But a little expensive.
In fact the plane on Soloys web site is the one i flew. It belonged to West Plains Skydiving in Spokane WA untill recently.
Ive also flown several 182's. Wing extensions are a great addition.
