Thinking of another V8 RRC...

clbarclay:
It depends on the system, most cheap systems are only single point injection which is not as good for a number of reasons as more expensive multipoint systems. It depends how many miles you do as to whether its worth spending the extra or not.

i,m in the middle of converting mine as for the waterproofing i have moved my coil inside the car and i,m in the middle of making a alumium plate in front of the dizzy so it will then be good in water

bigrapids_offroad:
mine runs like clockwork on gas and petrol.
im popping on the webber carb ive got for it with the sprintgas mixer then quick resray then it getting sold due to having 3 4x4's and cant really afford them all so im going down to my grand cherry for everything.

My v8 disco runs on gas better than on petrol, mainly due to some sort of sensor fault. The reason it runs better on gas is the conversion is of the mixer type.

If it was running the injection system it would try to follow what the cars ecu is doing thus any running problems on petrol would be duplicated on gas, if not exagerated. So in my opinion you are better off with the mixer type system.

1 it's much simpler

2 you can start on gas (also possible with injection but not ideal)

3 you can tune it yourself with the aid of a laptop or gas analyser. (on my previous car the lambda control system came with a handheld unit for set up so no computers or trips to the garage)

4 the loss in MPG compared to  the injection system is far outweighed by the cost of the injection sytem, typically 1-2 mpg.


I'm currently in the process of installing an injection system on my wifes renault megane. The reason is that it is better suited to that application as risk of backfire almost nil, however a properly setup mixer type should not backfire.

Any vehicle after 98 will have to have an injection system due to emmisions regs. pre 98 is a choice, Anything with a plastic inlet manifold is best with injection. other than that save your money and have a mixer system. if your buying a S/H range rover and find one with injection it's all good.

I get 12.5mpg and 14 on a run, I did enquire on the LPG forum and the gereral concensus is that these figures are about right for a gas converted landy.

Range Rover Blues:
Having had all 3, draw through, single point and multipoint I'd go multi every time.

It's by far the easiest to set up, once it's installed plug in the laptop and run "autocallibration" job done.

If it's not running right on petrol, don't ignore the problem, fix it.

Blue is currently still on draw through, it runs lean at high throttle so looses power but does save a bit of fuel.  When it backfires it's usually burning out a valve.

The LSE and RRR are both on multipoint for towing.  the system in RRR will probably end up in Blue now and the LSE just went to Whitby and back with 1,900kg of Elddis on the back, gas all the way :D Someone say you get more power flicking back onto petrol? not with multipoint :wink:

One final thought, a multipoint system will run fine with a snorkel.
