Running on LPG, Probably done but not finding it. Options

[Gunn1]

I have found info on the use of LPG in water cooled and stationary air cooled engines , but no instances where a 914 has been adapted to run on it.

While LPG is higher in octane, it has a lower BTU rating so Mpg would suffer. That said trying to determine the other ways a Type 4 would be affected by using LPG.

More longevity, more/less hp, run hotter or cooler......

Besides the conversion from a fuel delivery standpoint, would there be any changes needed from a cam, timing standpoint?

Did do a search and found no info specific to running a 914 on LPG, if you are aware of a link to a build or further info regarding the question I would appreciate if you would post it here.

Thank you

LPG, Just curious but why? (IMG:style_emoticons/default/confused24.gif)

Why?

The savings will never be greater than the investment if done right.
Tuning issues, can be done but mo'money.
A pressure vessel in a sportscar? ...and where are you going to put it?
Limited range.
Fueling connection issues.
Tax credit is a joke.

Might be OK for fleet, but one off personal car? (IMG:style_emoticons/default/rolleyes.gif)

Pollution and possible alternative to Electric

Ive looked at the EMV kits on the web and they are in the 7k range.

Looking into if it is viable alternative.

At this point what I'm hearing is no....

Just the weight and size of the LPG tank, and yes why!

The Electric version of the 914 has a heavy Battery in it, so weight of the tank is probably a non factor .

And electric cars have been known to have thermal events (Fires), just like the traditionally fueled 914's, so the fire thing is another non factor. as far as the tank being a bomb, looking at NTSB stats of all reported crashes involving vehicles using LPG tanks for propulsion, there have been zero. apparently they are way over built regarding punctures relating to collisions

To the why question, again looking for another lesser polluting type of fuel.

LPG is very clean burning, doesn't degrade the oil in the crankcase as quickly, longer service intervals for spark plugs and such, longer engine life.

And currently is priced right in this part of the US, forgetting about the tax credit.

Looking for a Greener, less polluting solution other than Electric traction motor .

Thank you

If that's your plan, you bought the wrong car.

[Mark Henry]

My brother had a propane chevy van, the tank needed was a big cylinder.
Good luck doing a clean install.

One of the cool things about a 914 is you can do so many things to them depending on your thoughts desires $$ and capability although over the years I've seen in my eyes some really stupid things done to our beloved little cars.
In conclusion you could likely put roller skates on a truck but why! (IMG:style_emoticons/default/huh.gif)

It was a simple question.

I didn't know if a conversion of this type had been done.

Thanks though for the input

I know your Google search button doesn't seem to be working on your keyboard, but I spent 30 seconds and found that the answer is yes....

Propane Porsche 914

One for sale even(old post)..and the question has been asked a few times on 914World already.

The link you included talks about a 69 chev pickup that was running on CNG and testing leaks with propane.

Not talking about CNG here, we are talking about LPG

So,a na engine built to +15:1 compression spec for the compressed gas can have good results.
The simpler route is the addition of turbos,with spectacular performance.
The clean burning nature of the fuel shows little oil contamination and carbon buildup,spotless.
Spotless after 500K km,on engines in fleet service,gruelling operating conditions.
The cost reflects the demand,the work must be done under strict licensed oversight here in Canada.
The kevlar pressure vessel is the most expensive option,followed by hydroformed stainless and steel.
The future greater use of the commodity means the cost should drop,the long term user reaping the most economy.

There was a guy..
Guards Red 944 in the UK that had the conversion done,a swell deal for the cost of the fuel.
Some print media(911+Porsche World?) from years ago,vaguely recalled.
Extolled the virtues and itemized costs,without raising the compression mechanically.

Huh?

See screen shot below, looks like 914 related posts to me.

veekry9,

I appreciate the info and the links you included in your response.

Thanks again.

I know a guy that runs his car and van on propane. I dont know much about it but he thinks its great. I converted my riding mower and it works fine. I didnt even do anything special just stuck the hose right on the carb where the gas normally goes in. I wanted to use up some of my propane tanks but no such luck. Iv been mowing my lawn for 2.5 years and the tank hasnt gone down at all. I think converting the 914 would be a great option. Way more better than going electric

[zipedadoo]

Might try propane injection. I know it works great on a diesel. Might give you an idea if it's worth it to go all the way.

Here is a 914/LPG conversion that makes complete sense. (IMG:style_emoticons/default/smile.gif)

Not looking for info on how to build a grill, I already have one.

Looking for info on converting a 914 to run on a LPG.

But thanks anyway.
