if your engine is running on LPG, can you still run nitro for that occasinal extra oomph?

I dont see why not. If your engine is built right to run on gas it should work great. I think that with most gas systems setup, the reason they are so gutless is because they are still built to drink petrol. Seals leak gas and everything. but if you have it built properly you will actually get more power from lpg. with your engine built specifically to run gas i think there should be no prob running nos. but you must make sure your engine will handle all that power . so a bit of money involved for a reliable setup.

don,t think you could run lpg and nitous unless you run a dry nitrous system with no fuel supply which will only give you 30-40 hp max ,as lpg and petrol will not mix and you need to supply more fuel with bigger nos kits . also lpg is already very cold and don,t know if the cooling affect of nos would be of any advantage . do your homework on lpg and get rid of any petrol (duel fuel ) and you will be suprised the power you can make on just lpg when set up

i dont have a vl calais turbo yet but am looking for one, i wanna run it on lpg and the car would be my daily drive. ive seen the other forums on lpg vl turbos. you could do heaps of kms with the foot to the floor and it woundnt cost a mint. i wanna do a rb25de head conversion onto the rb30 block. this site shows little work for good power http://trinity.frontierisp.net.au/~rowan/twincam.htm check out the dyno graph stand cams and its a beast the higher RON from the lpg would be good for more mods

Looks interesting indeed.

yeah you can do it. LPG is still just a fuel. Nitrous is an accelerant. Wack em together and boom. Happy Hunting
