V6 Xantia......... the beginning of another adventure

[CitroJim]

I used to get a petrol-equivilent of 50mpg out of my gas-powered XM Steve...

Always remember that LPG is not quite so efficient as petrol so it will not be a 1:1 relationship...

Convert litres of gas to gallons...

That's basically how I've been doing it, Miles divide by Litres muliplied by 2 = **** but that was just for my own rough guestimate.....

I used to get roughly the equivilent of 45mpg from that same XM. I'd think the V6 Xantia would be giving a very similar return. Which would be superb if it was, running a V6 and still paying less in fuel than an ordinary 1.6 Ashtray.

Not quite as clear cut as the LPG figure as of course it starts up on petrol, which is when the engine is at its least efficient.

When I was running the 4.0 Heep on LPG, I'd get a petrol equivalent of 32mpg out of it on a decent journey.

I finally managed to collect the struts from Will the other day, but as per normal, time hasn't been on my side, they're still in the boot of the C6, which is where I put them to fetch them home, It's looking like it's going to be Monday at the earliest before I get chance to have a look at them, one of the strut top's is most definate F....... err..... beyond economical repair the quite a large hole in it, the other one, is most likely going to a new home as I've already had a request for it to save another V6.

I should be off this weekend, but given the state of things with the weather it's been a bit mental at work, and now we're building up to 'the season of goodwill' (read drunken christmas party types) and "what do you mean I can't get back to Watford?"

I got the Northern Section technical day on Sunday, and that gives me a chance to take the Xantia over to Yorkshire, proving I can sneak in under the Pudding radar, I'm going in the company of a bomber (read XM) so I'll be providing the fighter escort...

I really love Christmas

The Tops is useless for a S1 WITHOUT The Spacer! If theres no spacer in the feed hole Steve one will need to be made or obtained, though, I know a man who can make them..

Its advice for your potential person who wants one depending what eira of Xantia they are fitting it to...

1997 same year as mine buddy, here's the posting: http://www.frenchcarforum.co.uk/forum/v ... =7&t=46831" onclick="window.open(this.href);return false;

Ah, wasn;t Wills a Series Two car?

Then they will DEFO need a spacer for it then! I fitted a Series Two top to a VSX and it needed the spacer before it would seal.

Ah, wasn;t Wills a Series Two car?

I've no idea, I never thought to ask.....

[citroenxm]

Yea it was... S2 tops are drilled deeper in the feed pipe orface, with a small step, and a stepped spacer needs fitting for the feed pipe to seal up properly.

[CitroJim]

Guess I'd better fire up the lathe....

Yip, sorry steve they are from a later W plate Xantia

One is certainly well past its best and would be for the bin although i confess im not sure if the polish man who can, could use it as a basis or not??

With the loss of power on LPG though you could technically decat the exhaust by knocking the guts out of a stuffed one and submit it for the test. It will still pass as far as they care
Also gives a nicer noise and small increase in power and MPG

You can usually get round starting on petrol with most LPG systems by holding down the cut over button on startup.
I used to do this on my coupe as the engine made so much heat and was so tightly packed anyway it was hot very quick Its mainly to make sure the injectors don't freeze, which they wont, as long as coolant is flowing over them Ideally they should be plumbed into the heater matrix return hose so it lets that get warm but then cools the coolant before it enters back into the block.

To be fair on LPG you can also get more power if you run hotter rated plugs as well as it can be mapped in knowing that the LPG calorific value is more stabilised than petrol is with its RON values, so can be setup on the very edge of whats in the tank and still be great. Injectors should flow about 50bhp each so your good for 300bhp on your setup although i'd reckon you'd only get about 220-230bhp after a rolling road setup with yours but the low end torque would be the real thing to go for so it becomes more of a cruiser and easy accelerator You dont need to run flashlube with your setup do you?

[Trainman]

Well, the bit in all that, that made any sense to me was the bit about the W reg Xantia after that it's double dutch......

anyway, here's a couple of pictures of the "beyond econimical repair" strut top





and here is the other one,



which you can see is beginning to go.....

[citroenxm]

That better one is FINE steve, Looks to be a NEARSIDE one, Im sure they Point OUTWARD slightly in the straight ahead position.

The rubber needs peeling away fully, and the metal plate needs treating to protect the plate, which actually still looks perfectly fine..
