Hello I was wondering what performance mods I should get on my jaguar xf s and what is my max HP that the engine can handle?

 

Crank pulley (sc pulley is optoinal if you are after top end since wiht the crank pulley it will overrun the super charger pulley efficiency) Crank pulley is easier to replace as well, pulling the SC pulley is a chore but come folks have developed a pulling tool but I have never used it.

with a tune you are at around 470HP (at least that what VAP says and had Dyno plots to show.)

I also did race cats, spires exhaust and ported the s/c. Not much more left without engine work. BTW this was all done on my XF-250 but just picked up a XF-S 2016 will be starting over.
