Has anyone upgraded their Throttle body? Seems like every other platform there are options to increase the TB except the Jaguar. I realize the tune would need ot change that's not that big of a deal to get done. If so what options are out there and anyone know the stock size of the 16 XJ/XJR ? thanks

 

I’m not aware of anything. “Bolt ons” for these cars is limited to pulleys and superchargers work from what I can tell. I don’t think there’s much to gain by a bigger throttle body ALONE on this car. The intake system is more than enough from what I can tell. The supercharger isn’t all that big by today’s blower standards and the added SFM gained and flow characteristics changed by a larger opening might be more of a withdraw than increase.

Besides, there are some VERY fast XF’s and XJ’s running the factory throttle body set up.
