How accurate are these compared to the drum type dyno? I've seen DC Sports, Greddy, Turbonetics, and HKS use this same for testing purposes. From my understanding the wheels on the car have to be removed and then serveral of these are bolted in place of the wheel. Any technical thoughts would be appreciative.

I've got another pic of it...

 

from my understanding, the dynapack is closer to real world situations because it can provide a load unlike a dynojet.
