thanks 4 the links

But WHY?????

My ute has been on lpg - the plumbing and the switch are still in place.

A 1200 can run on the exhaust emissions of the car in front.....

there's a 510 here in CA that gets over 500 HP using LPG/nitrous/turbo ;)

I was just thinking about propane injection the other day.

that's one of the troubles with LPG - it's really not 'injected' as such. it's more of a carby setup than anything - with the fuel being distributed on engine vacuum, not injected as pre-required like EFI.

i think there's a lot of research left to be done in this area, and it's looks promising that there really can be performance applications with injected bbq fuel.
