rear end ratio

Postby Jonathan3004 » Thu Jul 02, 2009 9:52 pm

I have a MY2003 4.2 XKR and want to know the rear end ratio (aka final drive ratio) for the car, does anyone know??

The reason I ask is that I have a bit of software called SpeedTracer which I got free with Autoenginutiy software which I can connect to the car whilst driving and it can work out BHP, 0-60 time etc. I am told it a reasonably accurate but I need the correct info to input to set it up. I also need the drag coeffeint but believe it is .35?

If anyone has used this software I would be interested to hear of your experiance with it.

Many thanks Jon

I have bought the AutoEnginuity PC-based package including the special Jaguar extension. I have found the package very good for the price.
I also have the Speed Tracer s/w but have not bothered to play with it yet - always something more important to do, it seems :roll:
