Just wondering if it was possible to supercharge a vehicle that ran on LPG?
The vehicle in mind is a 80 Series 1FZ-FE 4.5 litre Landcruiser.
Thanks to anyone who replies!

Excuse my ignorance but I have had a lot to do with one of these, and what the hell would you need to supercharge it for, drag racing, they go like a cut cat anyway.
If you must, I cant see any problem.

LMAO you thinkin the top fueler option?

No real difference to a Turbo, bit more $$, except on downhills, as the supercharger will keep producing power, and increase speed, where turbo wont.

No real overheating problems that turbos can cause too....

Lots more people going the SCharger way these days.

No problem what so ever. It actually will run better on LPG than on petrol due to the cold fuel . If you have a LP1 gas system you will need to remove the original sock for back fire and fit a manifold blow off cap. Have fun .

If you are serious about this , I would sugest a Turbo instead , although supercharges run straight off the crank , there have been more success stories with turbo's on straight six engines . If you were running a V8 , I would go supercharger any day . Do not try to use decompresion plated , they will put to much tension on the camshafts . make sure you put lower comp pistons instead .

The one advantage supercharges have over turbos, is that u dont have to have them running, u choose when u need the boost. However turbos are more efficient and are the choice of most people.

I think you have watched one to many Mad max movies lol . Works well in the movies but not in real life . There have been more success stories with turbo setups on Six and four cylinder engines as to KW.

There was a set up made with a air con clutch setup for the V6 holden engine, but didnt do to well . When the Blower was off the engine ran like crap

fatty, i dont believe turbos are more efficient... they are cheaper to buy and fit than a supercharger.
Boost for boost the belt driven POSITIVE displacement supercharger is more efficient (not to be compared to the impeller belt driven superchargers similar to those installed on commodores which is basicly a belt driven turbo)

and they dont have the lag or overun like turbos

Hey you can have them on a switch but as its wise to fire at top (or a litle after) dead center when supercharging you'd have to have a compromise if you wanted it to run half decent. Non supercharge ususally fire before top dead centre...but it can be done
i blew mine up and all did was take the belt off and away we went on our way back to adelaide...ran around for a year or so with it like that before I had the cash to get it fixed..thats when i was 17...

Yep we got it straight, they dont. LP1 in Melbourne used to get them in from the states. They are $2500 over there, so if u know someone over there who will help out, it will end up costing 4k.
