GAS how hard is it to fit?????

<< < (2/2)

Range Rover Blues:
I disagree.  My LSE is multipoint and unlike a single point system it ran (when new) with no loss of power comprared to petrol, at least that I could tell.  It also means you have no restriction in the air flow from the "injector" on a single point and there is no risk of backfire like with a single point, so no more sweeping up bits of air filter or having to replace the servo unit like on Blue.

Multipoint does of course work better with sequential petrol injection rather than the banked system fitted to classics, the 14CUx.  To get around this I fitted the manifolds front and rear of the engine rather than left and right so there are 2 LH LPG injectors and 2 RH LPG injedctors on each of the 2 LPG manifolds.  The manifold being part of the vapourised LPG delivery system within the engine bay.  On a OMVL multipoint system the LPG injector valves are mounted on the manifold whereas on my Romano system they are in-line on the rubber hose directly above the cylinder head.

I also found the set-up for a multipoint an absolute doddle, unlike the old draw-through systems.

Bowie:
All true, BUT, there's still no *NEED* to be multi-point on a Classic, thousands have run with a single point, open or closed loop, for years with no problems at all.

Set up is very easy if it is a closed loop single point, much quicker than a sequential, just twist an adjuster and watch the LEDs flash.

RRB, your 'no loss of power' may be down to how some multipoint systems actually fire the petrol injectors when under full load to get the last 10% of performance out of it, this is definitely true for Romano/Bigas N etc variants.

Also, as far as certification goes, some insurance companies require it, some don't, just make sure you have it on the list of modifications.

Range Rover Blues:
Tell the honest truth my Romano system flips back onto petrol under hard acceleration if the LPG tank is getting empty but either way it's noticeable that the lack of power I've experienced in single point systems isn't there on the multipoint.  My sister had a OMVL Dream XXI multipoint and that was probably a better system, again no loss of power even flat out.  Sadly that car got nicked.

Agreed that in theory at least a single point wil do the same job, LPG systems are probably not as advanced as petrol injection after all, but I suspect that multipoint may be slightly more economical, more driveable and less problamatic.

Very much as I had to though, you need to decide if these things justify the extra cost, for late model RRC, especially with the bigger engines I was advised to go multipoint and I'm glad that I did.

A 3.9 will run on single point and run quite well, you can even get away with a draw-through system (that's what I have on Blue).  You pays your money and takes your choice.
