lpg conversion

hi guys just out of curiosity anyone on here got an lpg conversion or know anything good /bad about them as when i have been reading through the forum i have never come across any talk(not that i was lookin i may have missed some topics) of them considering the thirst of our chosen cars i thought it might have been a high priority topic although i know the cost of the conversion is expensive

im sure ive heard it talked about before cant remember where or when but can remember someone saying that the scoob engines dont like lpg or something could be wrong like

I had a 3.9 v8 discovery years ago it had nothing but bother

Subaru engines do not like LPG, its due to the high running temps when using it.

a thought did hear or read something before was it on here jonny

Shame thought cause am sure LPG has quite a high octane value something 108-110

its the valve seat recession thats the killer unless you fit a flashlube kit to it

Yeah that is true, it does have a heigher RON value but it has a lower calorific value meaning you need a lot more of it to make the same power as petrol.

So realistically if you fitted a flashtube/lube kit, you could get higher gains powerwise out of running LPG on a Subaru tuning wise? But saying that if you fitted a 100ltr tank in the boot am sure it's around 70p per ltr, if the quantity needed is more to burn, ya pockets not really any better off is it? When I had the v8 disco back in the day LPG was 38ppl so it was the equivalent of running a 2.0 petrol, think the tank was around 100ltr in that which use to return about 240-250 miles

gas doesnt like to be heated too much, it can cause pre ignition in the inlet, resulting in potential melting of the inlet manifold, ive seen this on the gas gensets i commission when the gas is too hot on intake, or the timing isnt spot on which can singe valve seats out, the result looks like cutting steel plate with oxy torch
