Anyone have experience running an LPG conversion on a Type IV powered bay?

For real? No one? From what I can tell, slightly less efficient but cooler running and tremendously lower pollutants. Depending on the price of LPG in your area is either the same or slightly less expensive than gasoline overall considering the lower efficiency.

I was all up for it after going through the info at http://www.wps.com/LPG/index.html but I don't want to get into it just quite yet. They have those big 100 pound tanks if they would fit, that seem sufficient to run a bus, then a stove, a fridge and a light at the campsite.

All just a fantasy right now.

Bob Hoover either did it or researched it. I cannot recall now. Details are on the vintage bus list, which you can access through type2.com. Search "veeduber" and propane. He ended up going away from the aircooled engine, due lack of hp in stock configuration and to overheating concerns once the engine was optimized for LPG (higher compression and timing changes etc).

I'm still trying to figure out how to fill up the CNG on my F-150. 2 stations up here near the SF airport, but I need some kind of special gas card to use them.

Nice, I'll have to check out your system. I am looking to convert my obscenely large american hightop... and am about to build another bus engine, maybe for LPG use, or water injection??

it's at Serramonte Ford right now getting the GFI system serviced. Hasn't been used in years it seems so I wanted them to check it out before I started using it. You're more than welcome to take a look once I get it back.

2.09 a gallon certainly beats 3.19... plus it burns clean so you get karma points from mother nature Smile

There are answers out there, cost to yield, effort needed...... the list goes on, but it looks like I will proceed with a LPG system in the beast and see what happens, then it may be on to a bus depending on head temps and efficiency...

Hey Jason, you might find some info at http://www.cleanenergyfuels.com/ that's where I got a good bit of info on the CNG that I plan to use. There is also some info at http://www.cngvc.org/ where you can get a brohure with a list of stations that will give you a fill up.

The LPG interests me as the campers need it anyway, put a larger tank on there and fill it up (sans road tax) at any gas station or camping supply store.

Good point. I see those LPG tanks all over the place. Was actually thinking of getting a smaller one of those to run an after market stove I just bought from REI.

there's a UK company that converts bay's and vanagons. They've got some decent pics of their conversions online.

don't have the url handy but it's probably easy to find with google.

this is general type I information but the same applies to type IV. The challenges specific to your engine will be adequate supply of warming air to the vaporiser and adequate sizing of the system to your engine's HP. Optimising the engine's specs to run on propane is another ball of wax but the good news is you do not need to worry about preheating the intake as the fuel is already vaporised before it reaches the mixer (carb).

I like your idea! Many of my friends in Holland drive LPG cars and I always wondered why it didn't catch on here. One problem would be where to put the tank. Let us know how it works out! Very Happy

The tank can be placed in the fuel tank compartment.

Ideally you would have dual fuel capacity. The tank can be mounted anywhere under the vehicle, it is not as if we are driving Ford Escorts, they are campers, so one or more tanks are not out of the question.

Dual fuel? Meaning LPG and gasoline? Not going to happen.

Check again. With these kits you are able to (in fact have to) start and stop on gasoline and have the ability to cruise on either.
