2010 xfr what are the best bolt ons
 
Hi all I am new to the site and the world of Jaguar. I have a 2010 xfr that I want to bump up a little, put 20 mm spacers on the wheels that gave it a nice stance, I am waiting on my mina gallery intake, thinking pulley and x pipe mod? what are you doing and how do you like it? Thank you so much for your time and look forward to learning about my new baby.

Yes to 20 mm spacers if you have stock wheels, but better to go with after market wheels with smaller offsets. I really liked the Coventry Whitley hypersilver on my old XFR.
Put Michelin Pilot Sport 4S tyres on (unless it already has those or Michelin Pilot Super Sports).
Strong yes on the X-pipe plus pulley and tune, check out Velocity AP.
Forget the Mina intake, not worth the money, looks good but doesn't boost performance or SC whine.
Just my 2c.

Polybushes are a good upgrade https://powerflexstore.co.uk/jaguar-...xfr-x250-2008/

thanks for the feedback gents and I will look at velocity ap I have stock wheels with the spacers already installed like the look one day ill do wheels but the car came with brand new tyres. I already ordered the intake tube so if nothing else with put a little contrast under the hood. bushings are always a good bet but probably down the road for me

Adding a smaller upper pulley will do nothing for performance unless you also have it tuned.

Agreed.
And you get more bang for your buck from fitting a larger crank pulley (and tune) instead and it's much easier to fit (and reverse!) than the upper pulley.

oz is there really a marked difference going crank pulley verse supercharger?

Not as far as I know, at least with the V8 in the XFR. A little more power and torque with the crank pulley than with the upper (SC) pulley but not much more.
With the V6 the difference is marked as the OEM V6 upper pulley is already about as small as you can go and little is gained by fitting a smaller one but a lot is gained with the crank pulley & tune.
They main thing is it's a real PITA to remove the OEM upper pulley especially if you don't have a custom puller tool, and quite often it's also a PITA to get the new pulley properly on the snout as usually some intense heating is needed. Also AFAIK it's very difficult if not impossible to revert back to the OEM upper pulley without changing the snout as well.
No such problems with the larger crank/lower pulley, it's a relatively simple bolt off/bolt on job. But it does need a longer drive belt as well (supplied as part of the kit by VAP and others) and sometimes a new tensioner pulley, where the smaller upper pulley needs neither. The crank pulley also costs a bit more than the upper pulley.

oz I greatly appreciate your engagement in my question I do love the car in your sig. There is a shop in town that just does foreign work and is good at what he does so id get the stuff and have them install. soo im thinking do the x pipe install the intake tube I have and then save a few bucks and get the pulley tune and see what I got. I did not see a crank pulley option on velocity

wimmer,
Whoops, my bad!
I don't think VAP do a crank pulley and tune for the earlier XFR such as yours (with the Denso ECU), but the F-Type crank pulley would be a straight fit.
You would have to ask VAP if they do a crank pulley tune for the earlier XFR (they are very good to deal with), but if not you can always go with the smaller upper pulley & tune instead. Might be worth asking your shop if they can install the upper pulley without too many hassles.

There is one more headache with the upper pulley installation.

SOME supercharger snouts have sloppy casting issues and are larger than the inside of the smaller pulley. You have to make sure that the new pulley will fit on without binding/rubbing on the snout.

ECU Tuning did mine and my housing was too big. They had a “gauge” that they used to test-fit to make sure all was proper before they heated the new pulley and slid it on. They had to use a large file and clean the flashing off the housing in a few places.

That would have been a huge headache if you slid it on and it “shrinks” down tight and is rubbing on the snout.
