will add more on request
-
The coolant feed and return to the throttle bodies is missing.
-
Only a single point kit ?
Looks quite tidy bar the wiring over the master cylinder, will be interested to see how it goes for you with just a single mixer on it
-
why does it look like they have mounted 2 evaporators?
2) why on earth mount them next to the brake fluid tank..
3) ... err its a single point mixer? Why can't i see any injectors? :/
-
Bit dodgy how they have by passed the thorttle body heater for the water supply to the avporaisers...
-
I think that is an OMVL evaporator - big bugger!
Strange path for the hot water feed.
No injectors :o
Switch to petrol about 10 seconds before switching the engine off to get rid of the gas in the inlet trunking.

If its a single point mixer, is there not a possible case of a big back fire, blowing up the airbox?
Danny - have they installed a metal blow back on the airbox?
(basically a big metal flap on the airbox)
-
Danny, I hate to say this mate, but from what I've seen that's NOT an SGI kit.
And, they have made a real PIGS EAR of fitting it.
It's no wonder it's going to idle badly. If they've used the coolant feed from the throttle bodies it A) Won't get enough coolant and B) Won't get coolant very often! (As it's only a bleed-off back to the header tank!!
that feed can only come from one place - the bridge!
I would be driving it through their window at this stage, having paid what you did....
Classic example of why DIY is better :(

Yes it is a single point mixer and the entire inlet trunking is full of gas/air mix, if there was a back fire I would rather lose the airbox than the inlet trunking

Agree with Martin
If you were promised SGI you have been mislead mate. Two words.
TRADING STANDARDS!

I didn't want to say anything, but it took me a little while to work ut what they did.
That evaporator would not fit under the airbox.
-
The coolant feed and return to the throttle bodies is missing.
Looks like they've taken that off and diverted it through the evaporator. I doubt there'll be enough coolant flow for that, TBH, and it will only start to flow once the engine is up to full temperature. :-/

I thought it was a bit cheap - how does it drive?
And why was the loan car not LPG converted?

If that was sold as an SGI system I agree. It clearly is nothing of the sort.

Ditto to what I said above.
As before, I will confidently say looking at those initial pics, that they have made a complete hash up of this.
That coolant feed is totally inadequete.
-
Looks lite they've drilled the plenum on the left and fitted a single inlet for the gas. When tou have a backfire the MAF will kop it big time :o
-
Cannot believe what I'm seeing if this is a professional installer. I'd love to see this car in the flesh.

Can I get critical?
The water feed pipes are all over the place, the kit is not ideal for the car.
The evaporator is restricted to where it can go but looks like it is in the way
-
That's the least of his worries - but I agree
I'd be more worried about starving the bodies of coolant, AND insufficuent coolant for the evaporator
Its clearly not been done right.
-
Danny you were sold a "Dream" kit or something?
Is it this?

If so thats it with Injectors...
Danny, my advice, take this back.
As for a FULL refund.
Buy the DIY kit, speak very nicly to JamesV6, donate to his beer fund, and you will have a MUCH better sytem. :)

response from garage when i asked last week "the injectors are mounted below the plenum to give a more direct feed"
it's already going back tomorrow anyway, so having read all your comments, i shall be taking the printouts of these threads with me
-
Er.....they are injecting gas BEFORE the MAF which isnt good at all!
-

Are we missing something? Are there maybe injectors under the plenum?
Strange thing is... why is there gas going into the inlet then? And I can't see anything going from the evaporator to any injectors, so how does the gas get there?
Is there a chance we may be wrong? Or has Danny been had?
Still doesn't excuse that water feed though, that is a discrace...

I was thinking that, maybe they say they put the injectors under the plenum, so people think its SGI when its not...
Humm :-/
Danny can you see any leccy cables/pipes going onto the plenum area?
Better still pop the plenum off and take some piccies
-
just follow the gas pipe from the evaporator. If it doesn't end up at an injector block then it aint SGI!
This does look to be a single point mixer to me... and if it's SGI, then I've no idea why they are injecting gas into the inlet then!!
If you have a SGI kit listed on the bill/quote, then they have no case, you can take them to the cleaners...
-

they run a car sales too, and basically just gave me a car off the forecourt, which i didnt realise til today when i saw it back on there with a price in the window

paperwork says full multipoint gas system as does my deposit slip

I don't think that's a gas inlet, I think that is a vaccum for the vaporisor...
-
danny, can you go out now, with your camera, and trace the hoses from the evaporator and find those injectors?
Important to know before you complain.. .
-
unfortunately i dont have time to photo yet, today's a busy day, tis my birthday and seemingly not a good one :'( off out with the girlfriend so with any luck i might be a bit more cheerful later
I'd asked about the injectors straight away when i noticed they werent on top like i'd seen on others on here, and they said they'd attatched them just below at the sides, and showed me what you see on the photos just below the plenum on the sides
regarding coolant tank, this will be a new one to you all but they say they now bypass the coolant tank so it doesnt need the feed that Elite Pete mentioned in the first reply, the coolant still does its job properly, and they do the same on BMW and Range Rover
-
They are talking rubbish re. the coolant. Having seen that setup, they have
A) Taken a coolant feed away from a crucial engine component that NEEDS a hot coolant feed. AWFUL practice.
B) Taken the feed for the evaporator from a source which is not constantly flowing with coolant, and does not have a high flow rate (v small pipe diameter) so it's nowhere near sufficient to heat the evaporator and hence vaporise the gas, I suspect this is a contributing factor to the idle problems.
Regardless of the kit/injector issues, I am happy to say that purely based on the above two points, I would not let them convert my lawnmower, let alone a range rover!!
That feed needs to come from the coolant bridge, down to the evaporator, and then back to the HBV inlet. That is the ONLY acceptable way.

A friend of mine had a single point on his rangie 4.6 v8,had a new airbox every other week,not sure of make but was very problematic

Better to blow the air box than the inlet trunking

here's the update, i shall first apologise for seriously knowing LESS than nothing about engines, the injectors (yes there are some :D i had a proper look) are strangely mounted right under the 2 big pipes at the front of the plenum, which a mate of mine says means it'll never run right cos the pipe will then be pretty much the length of the plenum, but it definately isnt conflicting with the MAF cos they're still pointing the correct way
they're gonna add the coolant feed T piece (or whatever else to do that job) that i wasnt happy about, and they're gonna have a look at anything else that might cause the rough idle
basically they're gonna put it right, and in the words of my pal, "no wonder it was so cheap, looks like you got your money's worth"
-
Well, good to know you essentially got the kit you paid for, even if it wasn't installed right first time. The vapouriser would have been getting a very poor coolant supply, especially at idle, with that setup so I think what they propose will help.
Make sure they plumb the feed to the vaporiser by removing the pipe from the coolant bridge to the HBV and then plumbing the vapouriser between the bridge and the HBV. This will give you a better coolant flow than using T pieces.
I'm surprised at where they mounted the injectors. There's plenty of room around the plenum to mount them, and the pipes to each cylinder can be kept equal length and much shorter then.
Anyway, I'm sure there are a few of us on here who would be willing and able to help you neaten it up once it's out of warranty.

its been a weight off my mind, i had a feel of the evaporator earlier tho, it's definately getting red hot
apart from the lumpy idle, it runs sweet as a nut
getting a new fuel gauge fitted on saturday too

My guess is that the fuelling needs a tweak then.

noooooooo!!!
Thats no good, it needs a direct feed from the coolant bridge to the evaporator, and then from the evaporator to the HBV.
Its will always get hot coolant that way....

I did mine just before the HBV and return on the heater out - everything works as it should.
They do not need that much flow but do need the temperature

All works perfectly - no heater problems, no aircon problems- been converted for 20 months
