Hey guys and gals, I am new to Jaguar. I have a long history of high performance cars but not high end cars.

I recently purchased a 2010 Jag XFR and was wondering if there are any lower supercharger pulley upgrades. There are upper pulleys but those only add 1-2lbs.

Any info would be great.

Thanks

 

There is a thread on the F-Type forum from a tuner that is in the process of making 10mm and 20mm over pullies. They should work on all of the 5.0 supercharged engines.

 

Portland?... Arkansas - Colorado - Connecticut - Iowa - Kentucky - Michigan - Missouri - New York - North Dakota - Ohio - Oregon - Pennsylvania - Tennessee - Texas, or Maine?

 

And what about Victoria (Australia)?

 

Only reason I didn't mention Victoria, Oz, is that I didn't see any Koala Bears in the trees

 

Fair 'nuf, wrong sort of trees for Oz, koalas eat only eucalyptus leaves and none of those trees are eucalypts (AKA gum trees).

 

Yes...

 

Thanks by the way. I found that thread and am following it.

What oil do you all use in the supercharged 5l v8 engines (AJ133)?
I know the manual says Castrol 5w-20 but that stuff is only at the dealers. My car is no longer covered under warranty so was wondering if there is any other oil that would meet the requirements. Also is it just me or does 20 weight seem thin for a high performance supercharged motor?

Thanks

 

just chiming in to say hey to fellow Portlander ....Factory spec is for 20w....they are the ones that spent all the money on engineering IDK

 

No longer only at the dealers. Try Wal-Mart.
