A chassis dyno require that the tire grip the big wheel, An engine dyno BOLTS up to the flywheel. Higher output motors sometimes cannot get enough traction on the "big roller wheel" of the chassis dyno to prevent slippage. An engine dyno can also put more load on the motor since it has a friction device, where as the chassis dyno, you just accelerate a big mass and then extrpolate "work" done in an amount of time. I don't think there's a chassis dyno out there that can accuratly measure 1000 hp motors, the tires would spin. But there are flywheel dynos that can.
