LPG Conversion

[Boggie]

Hi all,

I spoke to Capitol AutoGas with regard to converting my car. They have quoted £2300 which by my reckoning will pay for itself in 19 months. Plus I have a G-Wiz, bought from a Doctor friend. I thought it was a good idea at the time but I was rather drunk. I plan to sell the Wiz to fund the LPG conversion. I like the idea of getting rid of one of the most environmentally friendly cars to help me afford to run one of the least. Of course this will also make the Monaro more environmentally friendly so it's not all bad.

Can I have any further recommendations for LPG fitters please? A friend at work and fellow HSV Org member (but I do not yet know his user ID) mentioned Linden Special Vehicles but they are closed due to a refit. Any of you got a Supercharged CV8, VXR500 or similar on LPG? If so, is it ok? My 'friend' has had lean mixture warnings when coming off the gas in his VXR6, it has been back a couple of times but CAG could not rectify the issue. Is this common or is he just unlucky?

Thanks
B

I had my VXR8 converted last autumn at MJH Hertford 01992 550 026.

Cost for me was £2440 inclusive of VAT IIRC. Apart from some hic-ups first weekend (pipe not done up). I've had no trouble.

I had mine done at Linden too, but as you say they are doing a refit. I think, although not sure they will do them in the future. It's only 2% down on power according to the graphs but you notice it more in the lack of throttle response. I also get the engine warning beeps sometimes on the overrun too but it hasn't been back yet for a retune. If you can get the maths to add up I'd recommend it if the cars a daily driver. If you do want the most fun you can convert back to petrol with the press of a button.

I can't see there being any issues with superchargers etc. I've seen supercharged Range Rover Sports that have been converted and Linden showed me a twin turbo LPG Monaro (I think it was twin turbo, but definitely a seriously quick Monaro). The only issue if you were they mentioned was you need 2 fuel feeds!

Forced induction and lpg are made for eachother, I'd like to do this one day.

Oh, another benefit is reduced car tax. I just bought 12 months tax for £200 on a 6 litre Monaro

im not technical but i thought having a charger that sits in the V you would have to inject the lpg before the charger and then the lpg could strip the ceramic coating off the blades? mines after the charger as its side mounted the turbo would be the same

Pls feel free to correct me as i am keen to learn

The guys at Capitol Autogas said they drill the inlet manifold and fit gas injectors next to the petrol injectors so I assume the gas will be downstream of the blades.
