THANKS ALL CHARLIE
Have got a 1997 Disco V8 auto with lpg, but the mechanical bits are pretty much the same.
It's got a BRC kit fitted - when it was first fitted it returned about
13mpg, I have since fitted an RPi A&R ignition unit and a set of Magnecor leads and it now gives 15.5mpg which equates to about 35mpg at the price I pay for lpg. Since fitting the extra bits it also drives much better and performs better on lpg than petrol.
With all respect to Julian, forget the RPi advance module. Get one from
TRH
With all respect to TRH, I didn't tell him to get an RPi unit, I just told him I had one and it has proved a good investment.
My Disco had never backfired and had covered 22,000 miles from new. A brand new set of LR brand leads were fitted when converted to lpg. My LR dealer who have converted 200+ V8's to lpg suggested trying the magnecors - throttle response was notably improved, the idle was smoother and modest increases in power and torque were shown by the dyno after fitting the 8.5mm ones. My Disco does not backfire even when switched from petrol to gas with the throttle open, maybe you should try some.
Thanks all for your input to Lpg .Very intresting I am 99 percent that I will have it done .I am thinking off useing the pepole from this site
I've read the bumph on the RPi site and fitting does not seem too tricky - does the
Graeme
p.s. our V8 runs on standard everything and cheap HT leads from Paddocks - I've had two backfires in three years and both times I was trying to squeeze the last bit of LPG out of it before switching to petrol .
And I was only trying to save the original poster some money. RPi products are over priced. I know as my 87 has an RPi 3.9 V8. Overpriced and not particularly very good.
The reason the 87 occasionally back fires and the 92 doesn't is because of the differing injection systems. The 87 has the flap type AFM with the mixer plate between the air filter and the AFM. Hence, when switching from petrol to gas the mixture leans out due to the length of inlet pipe between the mixer and plenum chamber. Magnacor leads will not change this. The 92 has the hot wire AFM with the mixer mounted on the plenum chamber so the switch over does not produce a 'dead' zone. Your Discovery will have the same injection system as this hence it will not backfire. If the throttle response was bad before fitting Magnacores, I would suspect that your LPG system is not correctly set up. The throttle response should be identical between petrol and LPG without having to 'fiddle' the set up by replacing the leads. Just because the dealer has converted 200+ LR's does not mean that they know what they are doing. I would NEVER trust anyone other than an LPG specialist convertor to do this kind of work. As Land Rover dealers have the reputation for extortionate prices and teflon coated sloping shoulders they are the last people to trust.
I have no wish to get into a flame war, but an awful lot of crap is talked about LPG, mainly from so called expert installers who have converted a few cars and think that they know it all. They then pass on their miss information to customers who believe it to be gospel truth.

thanks for all your help .Ihave booked in my disco to be done 2nd of september will let you all know what i think
thanks
I don't know the lpg-kits one but TRH recommends it and if it works as well as the RPi one it will be worthwhile. It doesn't say on the website, but it is worth checking before you order that the amount of advance is adjustable like the Rpi one.
No backfires here either, but the addition of the better quality leads was a notable improvement in throttle response and idle smoothness against a brand new set of LR branded leads. But if it ain't broke - don't fix it! :)
It was close wasn't it?

Bloody BY - I can never remember which order it's in either! :)
