Default LPG.Good or bad??? those in the know..

Considering a project in the future that would run a modern alloy v8 ls1 etc but due to fuel costs would have to run on lpg...

I have been told (true or not ) that the engine will carbon up and the lpg will knacker it

Is this true or just a load of baloney

Also any other downsides to running on lpg ?

Ta.

The engine should be perfectly happy on LPG, I have converted many of the slightly older LS series engines.

Kit wise, don't skimp, use a fully sequential system, Prins would work very well and has for me given proven results, good economy and reliability.

do they actually make the engine more economical as in, if you average 25mpg on shell nitro+, then lpg it, wouldn't you still get 25mpg but the lpg costs less to buy?

On average you lose 2-3mpg on a good setup, LPG is generally half the price of pump fuel, in some cases less than that if you find a better source for it.

I know two people who have been running lpg for years ( v8 jeep and a camper van) they have never had any problems.
The only issue I would have in my part of the country is the availability, I would have to go out my way too refuel.

Do it!

Result.been given rough prices of circa Ł1600 to convert,sound about right ?

Will all be done with proper paperwork as pointless otherwise

Now can a supercharger be a viable option with lpg?

Ł1600 is a fair price for a v8. What system is that using ?

No issues doing a supercharged engine, injectors would need to be suitable and you will probably need twin vaporizers. I've done a fair few f150 lightnings with heaps of power and they all worked great.

Not sure what system,was just testing the water so to speak

What set up would you recommend,looking at a pretty much stock spec with 3-360 bhp,as don't want to stress the lump but have plenty of torques

Supercharger would be a later mod

Phil Price in Wales. He uses it on all the cars I believe. The Escort was on a Romano system iirc.

I've only been involved with the higher end systems which are all quite pricey. Generally anything with a v8 in was around Ł2200 from memory.

If it was my car I'd use a Prins Multipoint system, one vaporizer, the biggest tank you can get in there ( tanks fill to 80%) of their capacity.

The only issue with Prins is I believe they can only be installed by dealers now as all vehicle info needs to be kept for their records.

I run my daily driver 1.8t audi tt on it, no problems with it besides takes bit of time to fill up tanks compared to petrol . I get 240 miles to Ł28 gas , do lose bit of mpg but cheaper cost of lpg makes up big saving.
