Title: LPG Injectors: Valtek Vs OMVL
Post by: tunnie on 13 August 2016, 19:38:36
If I do go the route of LPG'ing the 3.2, the two main kits on fleabay are the same bar the injectors.

£329 - Valtek
£339 - OMVL

Full Kit:

ECU STAG-300 ISA2 with wiring loom
Reducer SHARK
Injectors rail REG OMVLx2 3 ohm
Map/vacuum sensor PS-02
Buzzer
Temperature sensor

There is nothing in it price wise really, but what are the OMVL injectors like? I have Valtek on the 2.2, happy with them but with 3.2 need something bit more performance focused with extra horses it has.

Never heard of that reducer and pay the extra £10 for OMVL :y

Noted  :y

The flebay kits all appear to use this vap  :-\

There is also a lot less availability on the bay with LPG kits now, I've also never found any place cheaper.

Thanks, awesome link.  :y :y :y

The kits as whole don't do stag for 6 pots, but looks like I can build to order, doing 300 ECU + my own VAP choice

Current shopping list:

Vaporiser:

KME Gold 320HP @ £75. Silver does 240HP @£65. Think it's worth paying extra £10?

Magic jet rings a bell, can't remember if James had issues with them or solved problems.

Also with the filler, was it best to have straight exit or one with 90 degree bend?

The only injectors that solved all the issues were the Keihins that Chris put on in the end. Not cheap, mind.

Valteks weren't too bad but had the high RPM stumble. A rebuild of mine solved that in the end but then one of them got lazy.

The AC injectors can't cope with enough fuelling range to be useful on an Omega. It'll either be lean at high revs or won't idle properly IME.

See what you mean, £250 per bank  :o

OMVL good enough?  :-\

Magic jet were OK IIRC  :y  I think I was lucky... Mine idles ok (most of the time) and doesn't go lean. But it was more by luck than anything else I believe.

Get the gold reducer... For £10 you know it covers you.

Filler... Depends where you are fitting it but I think the 90 degree one is better :-\

Thanks LD  :y

So rather go OMVL than Magic?

I'm now looking at injector nozzles, I remember various discussions on this as some were too narrow/too wide. What was the tweaked size in the end that worked? Maybe little fatty knows best on this from his 3.2 conversion.

You don't need anything more than a basic M6 nozzle. These'll do fine:

Might even have a tapped V6 manifold in the garage you can have. Haven't looked at the "LPG bits" pile for a few years now.

2.6mm rings a bell but I really can't remember. I know we got mine right and TBE was too big.

Don't forget to add a tank frame and straps to the list  ;)

That site linked here is good, it has a kit for the tank of the extras including the fillers  :y

Well good job you reminded me, the kit has all the gubbins for the tank, apart from the frame/straps!

Given that the tank weighs 32kgs, and is the size it is, I am not in the least surprised ::)

When I've got the kit list together, see what they say. As I would need to take the kit to Brackley anyway, make sure have everything before work started.

Just took 3.2 to work today, school holidays so no traffic and managed a respectable 27mpg, so maybe 21/22 if gassed.

I'm not exactly light footed but I would expect to get around 240 miles to a tank on that run so you should expect about 250 I would think..

Is that from 80L tank? Considering I get 420 miles out of tank of gas in the 2.2, 250 miles will be a bit more annoying as more filling up. But 80L does fit far better than the 90L I received.

I could live with 250, as that's a week's worth of fuel.

My 3.2 does 270 miles of commuting mileage (urban and A road mixed) reliably on an 80 litre tank and over 300 on a  motorway run. I'll be amazed if you don't get 270 to a tank on a 50 MPH plod up the M3 with a bit of urban traffic either end.

True, but only if I actually knew how to change a clutch.  ;)

Sadly one of the Omega's has to get priority, as one of them will have to go at some point. I will need to consider a family bus in the next year or two, the reality is the 3.2 is in better shape and ticks more of my commuter boxes such as Auto/working aircon etc.

My tank is only 74L. And I hit a lot of roundabouts to go anywhere... 7 in the first 20 miles of any long journey ;)

And, as I said, I don't exactly plod about :-X
