Has anyone converted a 2011 XJL and added a super charge to it? I'm looking to add horse power to my vehicle. Any feed back is appreciated

 

Err ..... do you know that there is a factory supercharged V8, a factory supercharged V8 Supersports and the upcoming supercharged V8 XJR right .... ? Or the salesperson never told you that those versions exist?

 

It can be done, but may be way too much work. It would be much easier to trade yours for XJL SC.

 

Supercharger kits are available for various makes and models for around 7 - 10,000 US dollars. I don't think there is a ready-kit available for the Jag. No doubt, you could use the components available to custom make a kit but, it would involve a fair amount of custom work and fabrications which would likely push the price far higher than a normal trade-in for the SC model. So, unless you got some incredible deal on the XJL and have room to spend monies, I would concur with the other posters recommending a trade-in.
