Propane anyone?

[thespeedfactory]

Anyone run propane in the Bimmers? Just doing reasearch since Nitrous is $255 a refill here.

[xjeeper]

if you run propane, you will need a way to lean it back out again.... that is why nitrous and propane is usually stacked.

Popular in Europe .. where gas is $6 a gallon.

Do you have a link for info on setups for this?

Do you really consider a pressurized can of combustibles in your trunk a viable option?

and before any hooker chimes in about nitrous, no its not a combustible is is an oxidizer... :shifty

Considering that you drive your car around daily with 15-20 gallons of a combustible liquid that is FAR more volatile and arguably more dangerous than just about any other commonly used combustible fuel below your trunk already, I think the added risk, if properly contained and restrained, is nearly non-existent...

a little birdy with an e34 gets the credit

Propane works much better than alcohol. 3000gt/stealthTT's have used it awhile. ALong with grand national guys. I saw a supra with a bone stock fuel system (injectors, fuel pump and all) run 11.0 in the 1/4 with a single turbo pushing some decent boost. it richens the fuel alot more than alcohol. but tuning is a must or it will just kill the combustion. its really only a viable-needed option for those with BIG boost.

isnt it it much better on diesel engines!

are you asking or stating?

In either case, you are not contributing at all. ;)

wow thanks for all that valuable information. are you the contribution police?

that one comment you made contributed more to this entire site than any statement i have ever read! (cant ad smileys yet)

i used to be interested in installing propane injection on an m20 diesel (524td) and have seen many propane injected diesels from old mb's to duramax's. i even have a good friend with a chevy duramax that runs 13's with propane and nitrous! also i have seen engines converted to run off propane, and it is very common with rockcrawlers.

i have seen some gasoline fi cars run both, but i thought that propane alone just enabled one to run more boost safer. i dont know if it is because it cools the intake charge, or if it actually raises the octane level???

Really? I always thought it was more so the high pressure that made running propane more dangerous then regular gas?

I've heard of running it on large diesel's but I've never actually seen how it is set up, I do know that there is a slight carbon monoxide risk if it is not properly combusted, and that the combustion properties change as the volume of gas does. So I just figured it was a possibly dangerous pipe dream?

If someone can enlighten me I'd love to hear ways to make it work!

Propane pressure, in cylinders, is quite low compared to normal "bottled gases". It is a liquid (hence the term LPG) in the form as you see it in cylinders. The cylinders are relatively thin walled compared to those used to contain natural gas or hydrogen as compressed gases.

The primary danger, IMO, of Propane is that its fumes/vapor is heavier than air. If it leaks or is pumped into an enclosed space, it will fill that space from the bottom up and will not dissipate naturally. Thereby creating relatively high risk of explosion under those circumstances.

Would there be much gain if it was run on a NA engine?

^^^^^^^^^^^^^^^^^^^^^^^^

if someone knows the answer to my question that would also help us find the answer to yours.

Both,
LPI shoots liquid propane down the intake tract, it cools the intake charge, LPG is a high octane fuel, up to 120 :eyecrazy

But the fuel rail need to be insulated against the heat, you need a super duper high pressure pump specially made for LPI, the pressure need to be high to avoid boiling the LPG. Somewhere around 250-300 psi or having a very good heat insulation system and some way to get rid of the heat, maybe using the AC compressor and an in-tank evaporator :devillook.
Most propane we buy have a lesser octane rating, 104 to 110
Or live in Canada where we haul propane in buckets, since it's a liquid below -42°C ....
