Doing some minor research, as far as fill-ups, it is the equivilent of 104 octane but only costs a bit more than 93 octane equally--however, alternative fuels such as propane let you take off significant tax breaks.

Not too much to it supposedly...drop the stock gas tank in favor of a propane one, have a proportioning valve to change the stored liquid propane to gaseous before going into the combustion chamber. Thinking about this from a performance point of view, I think I could actually rebuild my engine with higher compression pistons and still run a decent amount of boost.

Cold starting isnt a problem with it, gas doesnt go bad over time (unlike the shit I have in my Supra right now, which is why it doesnt start). Also "automatically compensates for altitude adjusments".

Still looking very much into it and have alot to learn about it. What is everyone's opinion and thoughts?

 

Wouldn't it be a bitch it to find somewhere to fill up at night?

 

I know of two places locally off of the top of my head that I could get it refilled at

 

We used to have a Chevy Quad-Cab Dually with a 454 that we converted to run off propane and gas. It worked great in that huge truck, but I am not sure how well it would work in a sports car. The biggest concern would be the placement of the propane tank. We had ours in the bed of the truck. You should also compare the weight of a filled propane tank to the weight of a filled gas tank. You may want to have a small fuel cell for emergencies and have it duel fuel.

 

My old Crown Vic PI ran off propane or gas but i ended up taking all the propane stuff out, gas is easier to find and fill....

 

Yup the CNG Crown Vics.

 

I have a friend that did it to his silverado it was like a 96 with the 350 in it ran good nad everything although it didn't get as good of MPG but he got it cheaper...

 

I am new to the situation but I know of quite a few places that have the huge propane tanks designed to fuel the BBQ tanks. With the propane combustion system do you use a regular BBQ tank, or some special kind of tank/propane?

 

what about biodiesal. anyone though about that, it would probably be easy if yu were going to go to higher compression and bigger injectors, i know their are kits out their for toyota trucks so their is probably a kit that will fit atoyota engine.

 

I knew a guy 10 years ago that raced an old Mopar out at Sunshine that was a propane conversion. The garage that sponserd him was call Motorfuelers, but I'm not sure they are still in business.
