Any experiences of LPG in a 'quick' car

[digger_R]

As the title, do many people have experience of running a quick car but converted to LPG for obvious reasons.

I'm looking at changing my e39 528 for something more fun and was wondering if it was possible taking into account (seemingly) ever increasing fuel costs.

Friend of mine runs lpg on his 147GTA with no issues. Performance near as dammit identical.

My Impreza was on LPG, ran great but for full power petrol was required. Having it converted was the best mod I did to it.

I posted a bit more info in this thread http://www.pistonheads.com/xforums/topic.asp?h=0&a... Conversion - Experiences?

Mate of mine runs a Cayenne S (yeah i know its a 4x4 but the 4.5l v8 really does shift) on LPG,

It definately has lost some power when gunning it but not TOO bad to outweigh the costs, he normally gets about 60miles from £20 worth of petrol these days... savage lead foot syndrome.

My 3L V6 Peugeot 406 has been converted to LPG and has been fine. No issues with it cutting out and seems to get the same performance as petrol. Fuel consumption is slightly less but its working out at 12p a mile so about the same as an average diesel.
Have done 140mph (GPS) in it and it was still accelerating and have done many trips across France with no issues.
Although I took it to Belgium recently for my brothers stag do and forgot to buy the other type of adaptor so missed out on under 50p a litre fuel!

My uncle runs a 4.8 X5 with no issues

my old man runs a disco V8, that does have issues, sorted now though.

Someone I know has run a 2005 Mustang 4.6 GT on LPG and the car has done over 100k without indident.

Much of it depends on the quality of the LPG kit, and who installs it. I bought a P38 Range Rover which had already been converted, but had some problems running on LPG. I let some cowboys in London try and sort it, and the problems persisted. I then moved to Manchester and took it to another company and it runs like a dream now.

I ran LPG on a V6 4.0 Mustang for 2 years with no problems, would do it again in a heartbeat*

• if LPG got below 60p/ltr again

There's a few evos running on LPG and they run fine

Valve lube drip feeder is a good idea.


Try a kit on a diesel. Amazing power gains. Fuller combustion burn.

I have a Jaguar X350, 4.2 V8 (155 mph • 298 hp • 0-60 6.3 sec) been on it for the last 35k, no problems. Before that I had a 4litre 6 cycl Jag that was converted at 80k, and sold ... running at 325k ... no problems. btw the above are official figures not mine, I just sit on the motorway all day in it, which returns equivalent of around 50 MPG

Didn't think you could convert diesel engine to LPG.

You can't run it entirely on LPG, but have it added (I believe about 10%?), with the above described benefits.

The Palmersport Caterhams all ran on LPG last time I was there.

I think most of their cars now run on LPG.

I was out in the M3 which started producing a beeping sound half way around my go. It turns out it had ran out of LPG and switched back to Petrol, I was told on Petrol it would've been quicker - Maybe 5-10%.

Define quick?

I run my Lexus LS430 on LPG no issues. 0-60 at the traffic light Grand prix about 7 secs
A mate of mine did 90k in 3 years in a Nissan 200sx (tuned to 280bhp). 0-60 5.5 secs. In that time it was also tracked and dragged (although not usining the LPG for dragging)

Someone else I know runs a V8 4.7 tuned Cherokee (don't laugh its a bit mental - just watch the video) on LPG. He tracks it lots.

I run a E39 530 M-sport on LPG and love it. Slight reduction on power but only really notice when giving it some beans, but how often do people really push a car that hard on the road anyway (unless your one of these saxo toss pots I keep seeing). Not sure if you class this as a "fast performance car" but I find little difference between this and a friends Golf R32 but with half the fuel costs. As for numbers, for around £70-£75 I get 460 - 500 miles. Would be intrested to hear how cars such as E60 M5 or a V10 S6 take to LPG, because if the cost of gas stays low I'm sticking with it.

There are a few people on the HSV & Monaro forum running monaros and VXR8s on it with no bother.

can't be bothered checking but are these cars direct injection - if they are you can't LPG them.
I was looking forward to getting a Jag XF in the future....................but don't think it will be possible.

Its going to be harder in the future to find cars to LPG (Unless they sort out a direct injection LPG system)
