I wanted to get baseline numbers and I'm content with them.
My main reason for doing a dyno is to see how future mods will effect horsepower.


490rwhp and 471rwtq
If we use 15% drivetrain loss that's 563 crank HP.

 

Nice! And as a matter of fact, I do NV your Jag. I’m only at 470 Hp without mods. Though reliability is my main focus for the moment. I’m too deep in repair costs to jeopardize things. Maybe in 5 years I’ll change my tune (pun intended)!

 

Thanks a lot for posting that!
My 2014 XJR should be about the same.

nvMyJag;

What is the 2016 HP claimed by Jag for your car?

 

2016 is the same as all x351 XJR's (2014-2017) at 550 Horsepower at the engine. The 2018-2019 brought us the 575HP version.

 

Great numbers. That's about what I am pushing with spray on my 05. Its a handful to keep it running right though.

Enjoy your car, happy modding. It will be even more of a beast once you're done with it!
