Propane injection started out on big trucks I believe. A few of the guys in my off road club started running propane instead of nitrous because it was more stable, way easier to find, and after changing a few things, you can can switch to straight propane when you run out of gas. We dyno'd one rig running nitrous at 455hp, and switched over to the propane system and got 495. Biggest factor though, propane is cheaper and can be bought at Wal-Mart or almost any gas station.
