Hallo Freunde,

Fuel prices are killing these days, and i guess they wont go down in the near future.........
So, comments please!?

I've seen some 24's on LPG an advertising site... the money I spent on my engine rebuild and EFI could have been used for LPG... saves a lot of money indeed...but it doesn't feel right 
just fyi... it's not good for an engine to run on lpg... some modifications are needed (like hardened valve seats).
Engine wear is higher (especially the cyl. head), but if it's done good, 100.000 km is doable without trouble...after that you could expect some head work.

Any car that can run on unleaded petrol will be OK with LPG as far as valve wear goes.
As for high fuel prices: you might as well get used to them, guys; they're here to stay!

Thanks chris for the links,looks like a good idea to place the tank in the reserve wheel comp.but, what happens if someone hits you in the rear????
And,the tank looks very small.I guess you have to fill it after 200 Km??
The cost of the buy and build in is somewhere near 1800.-Euros, that will pay off after a year! (20000Km p.a.)
Well,i think about it.But,what is going to happen with my classic-car insurance?Do these guys accept it?
Any thoughts?

sure?
you don't want to know how much cylinder heads I see at work which have messed up valve seats because they run on LPG...
and those are very modern cylinder heads...
The seats that came out of my head weren't different from usual valve seats... at work we have special hardened seats...

But a replacement head is less than £50 its not worth the effort....

The 944 had a 75 litre tank ( from memory - I converted it for the owner a few years ago) but bear in mind that it will never be as efficient on LPG as it it is on petrol - typically uses 15% more LPG. Safety wise the tank is made from 4mm thick steel so it isn't going to damage easily! Also in the event of an accident where fuel is leaked, LPG will just blow away in the wind but petrol will form a highly explosive puddle on the floor.
My insurance company are fine with LPG on my old Jag which is running on a classic policy, just make sure that the kit is top quality and installed correctly.
Cost wise the set upon the 944 in the article would cost about £650 (UK) to buy and any competant person could fit it all over a couple of days.

Anyone else besides me think that this is just a plain ol' bad idea?
Aside from the fact you lose efficiency and power and perhaps increase engine wear (possibly all negligible effects in certain circumstances, but there nonetheless), you're probably adding weight and affecting the balance of the car... a car which is lauded for its low weight and balance!
These cars are, at heart, sports cars, not commuter cars. Kudos to you if use it as a daily driver but if you can't afford to run it (and let's not forget that these cars are already as fuel-efficient as many modern mid-size hatchbacks) then perhaps its not the right vehicle for the job you want it to do?
If it's just style you're concerned with, and you just gotta have a toofah to crawl through town with, perhaps it would be worth converting for you. I wouldn't do it even if you offered to pay for it...

Some guys running turbo Grand Nationals use propane injection to control knock but, as far as I can see, alcohol/water injection is still safer and proven (WWII aircraft and muscle cars).
Propane injection would be good if you could put a grill in the hatch. |

I don't think that's what Nobbi means
