On a gas car it actually works out very well. I am still considering it for my car. Advantages are:
1) you provide additional fuel without taxing your normal fuel setup via pressurized propane bottle
2) the added octane is like running race gas all the time when spraying further fighting detonation.
3) the fuel/air charge is further cooled due to propane being very cold when exiting the lines right along with the nitrous.
All that adds up to bigger shots without pulling as much timing and less worry about detonation. The thing I dont like is the idea of a propane leak in the engine bay...doh!!!!

That is what I thought too. (Motor failure with no warning). That is why I do not understand why someone would want to run propane on a juiced car that is already on the edge of detonation. Oh well.

Thats just it. Liquid propane has a higher octane rating than pump gas or race gas. So it staves off detonation while on the bottle. On a turbo car it is used again due to higher octane but also due to its much lower charge temps (not as cold as N20 but much colder than gas). It isnt widespread yet but it can be made to work. Biggest advantage is propane is cheap compared to the other alternatives.

Propane really shines when used with diesel acts as a catylyst. normally you cant rev over 4500rpm(diesel burns too slow) so your hp never exceeds the tourque reving to 6000rpm with a diesel propane mix can double the hp on a diesel.

Usually the guys running propane do not do it to increase the revs of the engine and that is a MYTH about diesel burning too slowly to achieve 4500rpm my friendhell my old isuzu Imark would run 5 grand all dayand also in experiments with motorcycle engines converted to diesel by an engineer friend of mine in CT revs of over 10000 rpm were normal. Epi the reason the engine grenade..think of this..I have a diesel with a static compression ratio of 17.5:1 and add 22 psi of manifold pressure from the turbo and then add some propane...too much burn to early is detonation in a diesel and with propane acting as a catalyst the propensity to bearn early is there..now with that compression ratio PLUS alreadyhaveing forced induction froma turbo...little room for error..a few guys int he club have chunked rods through the block the main reason they use propane is because it extends the mileage by a very decent amount enough so to justify the purchase of the propane.
