Jim Wolf Cam testing for the VQ37VHR -- Results inside!
Broken down here
C1 cam
This car baselined at 298hp and 227tq (This was after an uprev tune, on a motor with a cat back and intake) after the cams the motor produced 309.5hp 258tq to the wheels. So the real star of this was the torque increase in the midrange as that is very noticeable when behind the wheel.
C2 cam
With a baseline power of 268whp and 219ftlb, and a final number of 305whp and 241ftlb the gains were very impressive.
