Jaguar XKR convertible

Recommended Posts

New member having just bought 2003 XKR 4.2 convertible. Had an XF in the past and treated myself to a future classic. Already frightened myself a couple of times when the supercharger kicked in and still think it has plenty of horses left under the bonnet.post-5229-0-06554800-1403771375_thumb.jppost-5229-0-87806000-1403771413_thumb.jp

Welcome to the Club, Phillip.

 

Your car looks great.

 

Sometime my s type diesel frightens me when the second turbocharger cuts in when accelerating  ---   God knows how I would feel like with the supercharger!

 

Regards,

 

Peter.

The experts will correct me, Trevor, if [and I probably am] wrong, but I think that,while both perform a similar function, the turbocharger uses exhaust gases to push air into the engine, and the supercharger is a mechanical unit that does the same but with more power.

 

The Merlin engine used on the Spitfire and Lancaster were supercharged, but I think that turbochargers were used more in diesel engines.

 

Regards,

 

Peter.

Peter,

 

All that I know is when the XKR is in dynamic mode and the supercharger kicks in, it is well noisy !

P.S. Been ordered out to Minehead (love going up and down Porlock hill) now, as 'er indoors wants to buy some Steiff  teddy bears, do you want anything while I'm there ?

Thanks for responding gents

Think my 2003 version only has 400 bhp but that's more than enough for now - limited top speed is 155 mph.

Apparently 2003 XKR uses belt-driven Eaton rotor-type supercharger with intercooling, with helical rotor gears for low noise and coated rotors for maximum efficiency ­- at the time both industry firsts on a production engine.

All the best, Phil

Peter,

 

Wouldn't know, don't know what they are.

Northern delicacies, and black pudding [called pigs pudding in the Black country --  made from pigs blood and secret ingredients] is delicious especially with bacon, and Wet Nelly is left over fruit cake place in a dish with a splash or three of whisky or sherry on it, and weighted down and fed every day for a week until it has soaked up the drink, then it is able to be eaten.
