I know there isn't a ton of aftermarket options for our cars but. I am curious about a few things. I've been looking for info on coilovers but, can't anything definitive on what fits. I've found a few exhausts and tuners. Also curious about max rim and tires sizes from stock. Trying to understand why some sites say get a crank pulley rather than the upper pulley. Just curious what others have found. I've been googling for days and the info is varying and not a ton of sources.

 

Same. Ordered Mina intake for 2016 x260 also waiting to decide on pulley upgrade until i gather more info

 

I have read a few places now that the pulley on the charger itself isn’t worth changing fir the gain. There’s a larger crank pulley setup and tune that says it’ll get you to 450ish hp not able to find more info though

 

Eurotoys and VelocityAP both sell tunes and pulleys. You also have the option of tune only. I had the VAP tune on my 2015 XF and it totally transformed the car.

Tune no pulley gets you 416 hp and 350 ish torque.
Tune and pulley nets 450 hp and 440 torque.

I installed a Racechip myself.

You'll find more info on power mods in the Ftype forum.

 

Can anyone explain v-switch versus non v-switch? I am seeing that mentioned as well

 

Found my own answer. Reading is fundamental

 

how hard to install the crank pulley (lower)

 

If you search the F type forum someone did a how to write up. It looks fairly easy. Getting the car in the air is probably the biggest obstacle but that can be solved with jack stands.

 

I wouldn't say it is "fairly easy", locking the crank and keeping it locked while you undo the pulley bolts is (apparently) a right royal PITA.
And from all reports those pulley bolts are tight ***** with thread locker on them.
I like to DIY as much as I can and I'm not completely clueless with the spanners but I had a shop do mine.
