Couple of questions;
Firstly - has anyone had any experience of the AEB kits that Tinley sell? (http://www.tinleytech.co.uk/acatalog/Bigas_Sequential_Gas_Injection_Systems_-_Full_Kits.html)
Secondly, doing the maths based on ~20mpg on gas vs. 22mpg on petrol it looks like a saving of ~9p a mile assuming petrol is 133.9 and gas 79.9 (around here).. So about a year to pay itself back.
But assuming 40mpg out of a similar sized, newer, Diesel car, I'd be saving 12p/mile rising to 15p/mile at 50mpg.. somewhere between those figures is probably achievable (on a motorway run, which is where my 22mpg was from on petrol) - of course it would take (much) longer to pay back given the purchase price of, say, a 525d Touring.. but on the face of it, given the Omega has ~100k on the clock and is starting to show it's age, that seems a better bet, no?
I know, I know, if I'd LPG'd it two years ago I'd be quids in by now :-[ but then Mr Telio has done his disappearing act again now anyway...
-
I'm sure if a kit was ordered Tilo the shop keeper would suddenly appear.
Although Skinnytinker has had trouble getting hold of him last I heard...?
And if he can't catch him...:-\

Oh ffs, what's wrong with breaker?

..fe@ker.
Skinnyfe@ker. Him. ::)
-
Oh ffs, what's wring with breaker?
Yeah, that one keeps catching me. I like break and rather
-
LOL yeah - I've already spoken to LD and I know he's had basically no joy getting hold of the scarlet pimpernel..

I like your logic mate, however a drop of only 2mpg on gas is, unfortunately, dreaming ;) :y
3.2 Omega on a careful run - 33mpg petrol, 23mpg gas...
-
There must be someone there that can... Oh hang on, no, is that Jeremy eejit still about? :(
-
I get 17-19mpg from my 3.2 on LPG, and around 22-23mpg on petrol.
-
Aye? 33mpg..?
I've never had 33 out of an omega in me life...
-

I had 30mpg out of TBE (on petrol) and a constant 80mph from Swansea to Oxford.

3.2 Omega on a careful run - 33mpg petrol, 23mpg gas...
If it's a 10mpg drop then I'll only get 12mpg on gas on a run! There really would be no point in doing it, at that point.. in fact, LPG would be more expensive than petrol.. (27p/mile petrol, 30p/mile gas)
I get 17-19mpg from my 3.2 on LPG, and around 22-23mpg on petrol.
That sounds more realistic, although it still makes LPG seem like a silly choice versus a diseasel car of just about any description.. besides the "better the devil you know" argument.
-
My 3.2 Manual regularly achieves in excess of 33mpg on petrol between Aylesbury and Gloucester.... A418, A40, A436...
(not currently running on gas much, due to an idling gremlin since manual conversion!)
-
An 8-10p/mile saving on LPG is about right, though, IMHO.
But... Comparing one person's MPG with another's is futile. With LPG you will be paying about 65-70% of the cost on petrol, pretty much regardless of how you drive.
Is LPG really that expensive there? Fleet services on the M3 is 71.9.
-
71,9 at Shell shinfield, was not too unpleasant a suprise today.

This :y :y
-
Actually you're right, not as expensive as I thought when I last stopped by the BP that sells it - could have sworn I saw two 9's, but maybe I'm thinking of the motorway services recently; where petrol was also a hideous price (145.9p I think!).
So, then, it's back to.. anyone know if the kits Tinley sell are good/useful?

Give Tinley a ring and speak to charlie. Never has there been a more friendly, helpful bloke.
I don't have a bad word to say about tinley...

I'd say if you can find someone who'll sell you an AC Stag 300 it would be preferable due to the knowledge we have about them but, contrary to what the manufacturers will have you believe ::), they are all the same beast really.
The great thing about Teilo's kits were that he bundled everything required to convert an Omega down to the last hose clampinto a kit for £700.
Even if you only need a few bits and pieces, if you start having to buy things piecemeal, the costs will mount.
-
Indeed, a bit part of the reason I'm hesitant about a different type of kit isn't so much the kit itself, but rather the lack of on-forum knowledge about it.
I'll see if I can find some other route to getting the Stag kit, perhaps.
-
OK. Some things to consider:
Specify 8mm Polyflex hose for the fuel line. Much easier than messing about with copper and a 3.2 needs 8mm really.
A 4 hole tank is preferable to a multivalve setup as the latter are marginal on a 3.2.
Valtek type 30 injectors cause a bit of a stumble when changing up at high revs on a 3.2 on a Stag kit. I suspect they are a bit slow for the application. Not the end of the world, but might be worth avoiding.
-
Ta Kevin - the first place I found was offering Valtek injectors, couldn't for the life of me remember if they were the good or the bad ;) Mind the vap is also a "Magic Jet" good for 350hp .. which is also one I've not heard of.
An afternoon of Googling to be had, I think :)
[edit] On the face of it, injectors aside, this seems like a good deal (I think, reading it, it includes the tank): http://www.ebay.co.uk/itm/STAG-300-6-ISA2-KIT-LPG-AUTOGAS-SEQUENTIAL-6-CYLINDERS-/200805040365
-
I think JamesV6 used Magic Jet injectors once. Good reports, IIRC. Some people do seem to slate them, though, so wonder if they are a bit variable.
I would be tempted to splash out on a set of Keihins to replace mine if I ever got fed up with the lag, although the most recent Teilo kits came with AC's own, IIRC, and they seem OK. A few Omegas running around on them now with no complaints (actually being able to buy them aside). ::)
-
Whoops, was editing while you were posting :)
I might have a word with these guys (http://www.ebay.co.uk/itm/STAG-300-6-ISA2-KIT-LPG-AUTOGAS-SEQUENTIAL-6-CYLINDERS-/200805040365) selling on eBay, they certainly seem to sell everything you'd need, as long as you don't mind dealing with Poland direct.
-
Yep, looks OK. KME reducer, so all that kit is well proven on an Omega.
Can't see a serial lead for connecting it to a PC, but that's not a big issue. You'd need a few extras, and tank+filler+polyflex+mounting hardware. It would work out more expensive than Teilo's kits, I think, but.. you can actually buy it. ;)
-
That's a KME Silver Vap, we use the Gold but should be OK :-\
I'll give Teilo a try now ;)

He answered! But busy, now awaiting a call back ::)

Aaron, as I'm nowadays busy with a friends mondeo with all sorts of LPG problems, I'll recommend, you renew every ignition component and alternator including battery before LPG .. or you may end up with all sorts of weird problems.. :(

Not necessary unless it has previously been neglected. I'd advise new plugs unless they are under 15k old but other things should be OK if they have been maintained properly in the past :y
-
Yep, no need to go mad replacing things.
Of course, if you start a conversion on a car that already has issues, you will end up in a mess, but no sense in replacing parts on the offchance that they might turn out to be faulty IMHO.
-
The single reason I've not done mine yet :y

It seems that the tank and plumbing are readily available from them at the checkout :y what isn't clear is any extra cost for them :-\

As expected, it never happened >:( >:( Although I was too busy to chase him this afternoon ::) ::)
I'll try chasing him tomorrow ;)

I owe him an apology! The return call has come in. Aaron and TB, you both have PM ;)
For the record, he is no longer supplying AC Stag kits (apart from what's in stock) but is moving to a new, better, more cost effective supplier :y

Thanks CrippleBack. I still like Cakey more, as she does nicer presents for me ;D
Thanks LD
