XJR Supercharged V8 learns some manners of the wallet kind.....

It took us a long time to find suitable equipment to convert this car.

Only ROMANO equipment was up to the job. Now the XJR conversion is well established and we have all of the data recorded to convert yours with no problem at all.

XJR conversion number 5.

Yes, they are almost always Black.....

Here are a few pictures of our XJR conversion -

Wonderful, fast, affordable cars but they are quite expensive to run.

We teach them the economy trick, completing the package.

The latest generation of Romano multi point gas injection equipment allows us to convert the car so well that it is hard to find any difference in performance. Only the cost of running the car is seriously reduced.

Although there is not much to see (we carefully sited the electronics in dry and dust free positions) this is how the conversion looks under the bonnet from the left hand side.

Two reducer units must be fitted to allow the thirsty beast to run at its full potential.
The coin pocket in the lower portion of the dashboard is the best site for the fuel changeover switch. It is easy to reach and operate. Fuel contents can be checked at a glace but the display does not distract you whilst travelling at night .

For range we chose a four hole 91 litre toroidal (spare wheel) tank. To fit this tank, we have to reshape the boot floor a little and move the battery over as far as it will go. The floor panel is raised a little with this option due to the height of the tank.
Here is the 70 litre tank option. Plenty of space left if you carry a space saver spare wheel.
The LPG filler is placed at the bottom of the rear bumper, just about the only position that will conform to regulations but remain easy enough to use without kneeling. A coil is put in the filler pipe to prevent breakage during a rear - end shunt, but even if the pipe where completely severed the multi valve would stop any significant leakage. All that can escape is the gas content of the pipe since the last fill.

For those who have not seen this type of filler before, it is of the 'fixed bayonet' type, the only one that is certified for use by the LPGA.

A recent (30/03/06) comment from the owner of this car by e mail;

'Now I have 370 BHP Jag with no faults, that runs on LPG 99% of the time and does the equivalent of 33 mpg around town and 40 mpg during 80-100 mph motorway driving.'

'This is probably more than I had hoped for.'


Our own XJR V8 doesn't get driven slowly but it returns 18 MPG consistently on LPG.

Taking the most up to date fuel costs for Petrol (1.20 / litre) and an average cost for LPG (.54p / litre) gives a cost adjustment factor of 2.22.

2.22 x 18 produces a cost equivalent mileage of 39.99 MPG.

What car with that kind of performance can do so on petrol or Diesel?

Before we can give a price estimate and book a conversion slot for any XJR V8 model you must read this item on NIKASIL lined engines.
