The chassis dyno is awesome. It is cool how much more accurately you can set things on a dyno when everything is in the car as it is when you hit the track. Notice on the front view the slight hesitation when the RPM's drop and he gets back on the throttle. You can see the roll cage shake for a split second. You'd never be able to see that on a standard dyno, let alone make the right adjustments to fix it. They can do any type of car.
