Is this within the wheel/axle itself? Interesting... I would expect a smaller wheel (lighter mass) to have a higher resonant frequency.. unless this is related to the roller rotation speed. Any links to more info on this would be appreciated. Tnx
The wheel speed gets so high it actually starts to vibrate, just like a tuning fork. You can't feel it in the car, or even catch it on the dyno. It happens so fast. You can add spring load and maybe, MAYBE get through it, but of its in an RPM range you hit and hold in the burnout you're dead before the green comes on. Also, the RPM range can be a few hundred RPM or 1500 RPM in extreme cases.
