It would be all over the place depending on butane mixture rates.
Like all fuels we should be told MON not RON as that gives us a better idea how good it is.
Hey don't think I am putting down LPG, just look at my avatar, just I won't hide problems with things like others might! I am pissed with the mix we Aussies get. Anyway it will most likely have a higher octane than PULP if you keep the intake temp down, unlike petrol, gas goes into the intake as a dry fuel, petrol goes in as a wet fuel, it becomes the gas in the combustion camber, that change absorbs latent heat (similar to how the gas in an air conditioner system works), gas goes in dry so this never happens, also a wetting of the intake walls with petrol cools the intake charge. Sorry for my poor explanation.
Keep the intake temps down and you should out perform PULP petrol that is not using any additives as this will allow higher boost.
Not to mention you will be using a fuel that is better for the environment, increased engine life and cheaper.
Damn hard to kill yourself with LPG if running your car in a shed, as it produces very little carbon monoxide and far less carbon dioxide.
, check this site out, they have some interesting results.
I reckon I could make one of those intercooler intakes if I had better pics or the design. ( :s6: Well I reckon my mate could and I help! :s5)
