I am taking my XJR to the dyno tomorrow morning to see what she makes. This is purely for fun, I know I can't tune it.

Is there anything I need to worry about regarding the car allowing me to do the pulls? Some cars freak out when they see a different speed between the front and rear wheels like this. I just want to make sure I won't have any problems.

 

Turn traction control off before doing the pull of course.

It'll throw an ABS light/error and disable ABS after a few moments of front/rear wheel speed discrepancy. This will fix itself after a engine off/on cycle and a minute or so of normal driving. Don't think you should have any other problems. Vehicle speed is determined by RR wheel speed sensor so the transmission should be fine with a dyno.

 

My LS-swapped XJR has been on a dyno a couple times last year without issue. OEM traction control and ABS retailed and functional. Let us know what the wheel hp and torque values are.

 

What happened with this??
