Anyone ever converted an XC90 V8?
 

As above really.

I'm looking at getting myself one for family duties, so was wandering if it's ever been done?
Don't know how the Yamaha V8 would behave on LPG, or even where the tank would go as I've not even had a good poke around one yet.

Cheers,

They have and can be done. The do need a well specced system. Tank if you go for one in place of teh spare wheel there is not a great deal of space. You can fit a 65ltr in or a bit bigger if you add a skid plate

Even in V8 form, are you sure? It's a tart's car. A homoerotic, hairdresser's shopping trolley, come pram... all but a quick one;)

Careful now, drive it for long enough, and you suddenly find you need a bus-width to get through anywhere. I'd get rid if I were you, before it starts. Their owners all seem to struggle. Must be catching.

And don't leave it too long? You might er..

Turn.

If you're walking towards it, teapot fashion, I'm sorry.


It's probably too late.

Erm... Yeah.

Too late.

Did you get the lpg conversion? How much did it cost and any drop in performance?

They can be done - I was looking at one on e-bay last year.

I dont think he has done it yet.

Performance should be the same on both fuels

really nice!

looks well in black.

That pram;) would look good down Old Compton St.
I'm sure Classic will correct me, only you'll always get some drop-off in torque/power simply because the gases are able to run higher compression ratios and advance over petrol. And with the engine hobbled by the fact that it needs to run petrol some of the time, you can't up the CR to the higher levels the gases would like.

Advancing the ignition when running a gas conversion offsets this but not all the way. The 'Gas of the Gods', CNG needs highest, followed by LPG. If hte engine had its valve timing, CR, and ignition without consideration to the BiFuel petrol requirement, I summise that you might actually see power increases. CNG is in many ways, and LPG to some extent, superior to petrol. For kick-off there's littel sludge creation, and no neat fuel to flush the oil down the bores and no issues with fuel atomisation and metering to gas, because it's already a gas. But the car has to be set-up for lower compression ratios etc to run petrol too.

You wouldn't drop your CR for petrol and expect no ill effect would you? Well, you're doing this with LPG, whereas any old skool boy-racer knows skimming your head is the route to cheap power.

Is gas better for yoru engine?: My engine oil back from Blackstone Labs after 28,000 miles had a report to change it at 30,000 next outing. Try that with petrol. CNG is very clean, and LPG cleaner.

With a NA engine there is some power loss. This can be evened out by using atiming advance processor to advance teh timing. Higher CR would be better but would cause issues with petrol.

Turbo engine dont have the issue
