And the curves are different profiles.

yeah it was a whole lot different than the dynodynamics...heck i was expecting a whole lot better on the dynojet.
My torque on that surprised me.
As you probably know, with a dyno dynamics dyno (and a dynapack as well) you can adjust how long it takes to go through the pull from start to finish. If it is set up for a LONG pull it will give you better torque readings because of the longer spool up time for the turbo. A dynojet on the other hand the length of time a pull takes is completely dependent on how powerful the car is. Comparing your graphs this also shows up where the dyno dynamics torque peak doesn't show up until 4000 RPM, but the torque peak on the dynojet was down at 3500 RPM. As far as the difference in peak HP numbers I would atribute that mostly to the difference in the transmission gear used on the dyno.
Doing a short time pull like Shive did puts less stress on the engin (a great thing to do on California pee water gas) but gives a lower torque reading on a car with a fast spooling stock turbo.
