after reading the post on mpg and bec i was wondering about converting my bec 7 to lpg after a sva, any one done this .... thoughts and ideas anyone.

You need to do a lot of miles to make an LPG conversion worth it.

Plus I'm not sure a highly tuned high revving bike engine would take too well to LPG either - could be wrong though!

Cheers

i've been looking a lpg converstion for raod cars and they all say theres only a small drop in bhp and mpg other than that it shouldnt do and harm to the engine as it burns at a slightly lower heat.... but a bec doing 20-25mpg and lpg being less than half price i wouldnt have to do many miles to get my money back...... besides that i dont even know how to do it lol

My works car is a Dualfuel Astra, it is 3 years old and has done 150,000miles, my boss got a £1500 grant to buy it, and I can do about 300 miles on £18. It sounds like an Impreza, and drives like a Rialto, I have to switch to petrol to overtake!

My own tintop is a 1.2 Punto, which does 65 mpg on a run and 50mpg locally

My locost does 28mpg in 'normal' blatting, but with my speed shy Mrs onboard, will do over 50mpg

Isnt life too short?

I run my range rover on LPG, its a decent sequential system and it goes better than on petrol.

LPG has a higher octane rating but a lower calorific rating, in real terms you can run a higher compression ratio, up to 13:1 I believe but get slightly less power.

For me it saves a heap of money, but at 13-15 mpg on petrol its not surprising.

With its multiple carbs you would need around £600 for a sequential gas front end, so would need to be running some form of injection, alternatively you could just buy a gas vaporiser and injectors and use something like megasquirt to deliver the gas.

nb/ all the cars at palmer motorsport run on LPG, nothing slow about them.

Gas is good but aim for 10,000 miles before it pays for itself

I thought that a lot of the tax releif on LPG will be lifted within a year or so, which will make LPG a similar price to other fuels anyway?

I recall a similar thing happening with good old diesel... now look at the price of it. ATEOTD demand/supply = price.
