Re: Random Misfire Cyl4

Burned valves give more symptoms at low rpm and low load than at higher rpm and higher loads... LPG at correct mixture doesn't burn valves but petrol at lean mixture or LPG at lean mixture will burn valves. LPG on vehicles that need a lube system for LPG but don't have a lube fitted will cause VSR w...

Re: Most economical budget-car conversion

little 3 pot engines are ok but on petrol, on LPG they lack of performance. You need to rev that 3 pot so you won't get decent economy. A little na 3 pot isn't going to be good on performance but an LPG conversion shouldn't make any difference to that performance. A lot of 3 pot engines have furthe...

Re: VW 2004 beetle lpg problem

This does seem to be a problem with the car itself as opposed to an LPG system problem. The only case in which I'd suspect otherwise in this situation (though still unlikely) is if the LPG system is connected to the canbus/OBD (to read fuel trim data), with a Prins system that's unlikely but possibl...

If it can be set up to do it on petrol it can be set up to do it on LPG.

Re: MB GL 450 engine start problems

In addition to all the usual advice about gas leaking from reducers/injectors etc... Are you reading petrol fuel pressure via obd? If so it will need a petrol fuel return fitting (or at least an electronic petrol pressure emulator) if not already fitted and working. Bad starting (on petrol) can simp...

Re: lpg feed pipe size on 500 bhp engine.

Sorry for the sucking eggs recap on drilling nozzles! Most Valtek 30's have internals that will only flow as much as a 2.5 nozzle, so even if you fit bigger nozzles they'll only flow as they would with 2.5 nozzles anyway. The 3.75 manifold nozzles on your Astra won't be doing any metering, the restr...

Re: lpg feed pipe size on 500 bhp engine.

You'll need to drill the injector nozzles (jets) to 2.5mm and refit them, you can't meter the gas at the manifold end it has to be done at the injector end. If you try to meter gas at the manifold end the injector still pulses out the same amount of gas almost regardless of what restriction you put ...

Re: Cornwall Autogas Coperative

Just spent 2 weeks in Cornwall, filled up with LPG no problem usually at Shell places on the A30... Hayle, is it? and another place on A30 closer to Newquay, both not far from Truro really. Filled at Victoria services and near Launceston too. Haven't used any petrol in 700 miles within Cornwall incl...

Re: Good installer for a type r in the north east?

Thanks Gilbert.

Valve saver is necessary but would be the least of concerns if the rest of the LPG system was fitted by an installer who isn't really very good at the job (or thinks good results on a type R will be achieved doing one of their run of the mill conversions).

Re: lpg feed pipe size on 500 bhp engine.

No probs Rob. Yes I did, and you could have the single injectors mounted directly in position on the vac side of each individual throttle body with pipe lengths between injectors and gas entry points only about an inch long, also drill the injector nozzles out to whatever size you want (can't do tha...

Re: Shell removing lpg

Not really anywhere for an underslung, not without having to fabricate a replacement petrol tank to free up some space there. I've got a 680 x 270mm 78 litre tank in the wheel well at the moment but could squeeze in a 720 x 270mm but that wouldn't give me much extra. If I went for a full toroidal, ...

Re: lpg feed pipe size on 500 bhp engine.

Possibly an age/use thing, do we know how old the BRC injectors are? Or a lube thing (if the injectors were previously used with a through injector type lube), or just bad luck. Yeh not serviceable and not something any cleaning fluid will fix. OMVL's beat a lot of more expensive injectors on perfor...

PM reply sent. As it was converted a few years ago records will be on an older computer so I'll have to dig them out before knowing what LPG parts are fitted.

They have an underlying fuel trim (the S2 trim I referred to).
