Does anyone run their wedge on LPG. I am well interested in this subject. The wedge is probably the perfect car for LPG the boot is massive so a good size tank is`nt a problem and because the roof sits flat you can still fit in a bit of shopping. In China LPG is very popular you cannot tell the difference between petrol. The Buggatti EB110 holds the speed record for gas at 212MPH as the same car runs 218MPH on petrol I don`t think the performance has been harmed too much.
What does everone think - should a TVR run on petrol or can you still get the sound and fun out of much cheaper and greener LPG ?
P.S
Has anyone got a Lucas 4CU fuel control unit, part number 83986B for sale ? e-mail me if you have and tell me your price !!!
In Holland loads of cars use LPG. I don't know who told you but driving on it not the same as on petrol, in direct comparisons LPG is almost always very noticeably sluggisher than petrol. Don't know about the top speed but acceleration is definitely less. Which may be considered not good in a TVR...
Well - its taken months to surface from first post but there is indeed a TVR 400SE running on LPG ..
Below is the owners response to the question of living with an LPG TVR:
The 400 was converted to LPG 2 years ago at a cost of £1100. LPG costs 38p per litre consequently returning pro rata 52 mpg. I think you will agree this is outstanding! Never had any problems with the conversion or LPG. Until recently, the average mileage in the TVR was regurlarly 350 miles per week, so the LPG was and is cost effective. The major conversion expense is the tank. I have a 55ltr cylinder tank in the boot with space left over for maybe two sets of golf clubs. Two years ago LPG conversion was in its' infancy but has since grown with many more filling stations available. If you intend to keep your 400 for some considerable time, LPG is the way forward for gas guzzlers. Its cheap, efficient, clean and safe.
So there you have it...
Interesting to see someone who took the plunge.. who knows if any will follow..
The car is currently for sale - I have advised the owner of tvrwedgepages/pistonheads classifieds so it may well appear shortly..

Thanks for the update Wedgie - passed your comments on and have received the following answers which makes interesting reading for those who have ever considered or are considering changing their TVR to LPG.. I doubt conversions on TVRs would catch on despite the obvious benefits of having the best of both worlds... 
"55 Ltr Cylinder Tank: Fits nicely into the "shelf" section of the boot making the whole of that rectangular area redundant and gives an approx range of 200 miles - moderate driving.
Insurance Premiums: Prior to conversion, I checked possible premium increases with my insurer only to be informed that insurance companies were very aware of the increasing popularity of LPG and as a consequence no levy ensued.
Handling: No discernable difference - but it should be noted that I never
push the car to any where near its' limits. I NEVER have full petrol tanks and LPG, this would be stupid and totally unnecessary. The only time I broke this rule was the fuel shortage and I could feel the extra weight.
Performance: I find the LPG is fine for everday driving, including motorway
cruising at speed. Should I wish to "play", especially with another high
spec vehicle, petrol is a must.
Fire Hazard: Hhhmmm! The most expensive part of the LPG kit is the tank - supposedly because of the robustness and hence safety related issues. I
have to take that as read.
Air flowmeter: Blowback damage is again supposedly pre-empted by a rubber gator affixed to the LPG intake/ airflow intake housing.
To date, I have no need to doubt any of the info forthcoming from the engineer who fitted my conversion. If you have heard anything to the contrary, please pass this on."
