AMUSE 370z puts down 403 hp 342tq

Jordo!

Accuracy in terms of repeatability can be gotten on any dyno -- HOWEVER, there tends to be greater variability from shop to shop (i.e., dynamometer unit to unit of same brand) in dynapacks, mustangs, and other load holding dynos, which tend to have a great deal of variation in calibration parameters.

I personally prefer dynojets simply because the degree of variance from unit to unit is negligible. It just calculates speed of rotations of the known and constant weight of the drum (roller) and then interpolates torque.

That means (transient factors, such as ambient heat and humidity not well accounted for by correction factors, notwithstanding) a dynojet reading from one part of the world is much more comparable to findings from any other dynojet anywhere in the world, whereas the same is not found to be true for most other dynos, all of which may be calibrated a bit differently.
