Hi. Does anyone have suggestions for enhancing the overall performance of a 2006 XKR? I looked online and saw some equipment upgrades from Mina but i don't want to harm the engine. I also looked for sound upgrades to the muffler system but there again, it's hard to tell without being to hear the outcome of a swap. Any suggestions would be appreciated.

 

I just updated the cars that i own but they don't appear on my thread. Anyone know how to get them to show? thanks.

I noticed some time ago my signature does not appear on phone posts but is present if posted via my PC.

 

Supercharger pulley upgrades combined with an upgrade to the intercooler pump look to be the most cost-effective safe performance upgrades. There's a few threads around here about which pump to use (I think it's a Hella pump from an AMG that requires some minor wiring work). As for exhaust, I recently completed my journey through a few different combos of muffler deletes, and have posted the story and sound clips here. https://www.jaguarforums.com/forum/x...-drone-236969/

 

RogPerez,

You can go to: eurotoys in Chicago... They have all the things you need such as Big and Little Pulley Kits, Large Intercooler Radiators and Pumps. Most all the things you would ever need to build-up Boost pressure....A Big Crank Pulley is the overall secret, along with the small Pulley on the S/C itself.....The Large Intercooler and Pump help keep the Heat down and the Power up. That's 80% of all the power you will get unless you want to spend $10,000.00 or more!+
