370z powerband vs. 350z powerband

The REV UP improved power on the high end, but sacrificed a bit of bottom end. The HR is the best of both worlds, and it is still a potent motor. The VQ37VHR is basically incorporates electronic intake valve control. There is a standard intake cam, and there is another "cam" above it that serves as the actuator to control intake valve duration and lift. So with this motor, the computer tries to optimize efficiency.

I had an '03 Z for 6 years, and I miss the bottom end grunt the 370Z sorta lacks. However, what the 370Z lacks on the bottom end it makes up past 3k RPM. It pulls hard to redline. The car definitely feels lighter on acceleration.

[EDIT] A couple of shops here have posted up dyno charts for comparison. It has been tooo long.
