Default Chassis Dyno : Anyone have any experience with one

Here at work we are looking at possibly buying a chassis dyno and I was curious if anyone on here had any real world experience with one and had any insight on them and maybe some input on one brand over another. Thanks a bunch.

I went back to school for a semester or two after I retired at Pitt State. I believe their chasis dyno was a Mustang. It worked very well on street cars and pickups and was very consistent. The electronic traction control had to be unhooked or you were in for a terrible ride. With a spool you had to be sure the tires were almost exactly the same size or you ate up a lot of tire. I don't think we had anything above 475 hp on it. We tried a 700 ftlb (?) hopped up dodge diesel and drove through what the dyno would handle. As I remember it used electric motor/generators as a brake.
There was a gentleman who showed up with a inertia motorcycle dyno that was deadly consistent. I would love to own the automotive version.

An inertia chassis dyno is the one to have or use. I had my car on one last week and the owner stated it will place a load on the engine like it is going down the track. It was a Mustang brand dyno. This place tunes diesel trucks and twin turbo cars with this one. So it must be able to handle high HP and TQ.

Not sure that it means much, but the operator had an app on his phone so he could change settings without having to get out of the car. It was paired to the laptop for the dyno. They also had additional rollers that were not in place, possibly for an all wheel drive car. I will be going back in a couple of weeks, if I can get any additional information for you let me know.

I had a very busy Dyno Jet (Inertia) chassis dyno for about ten years.
Good for a lot of things. Not the last word, the race track is. Repeats better with a stick car. ATF temps effect converter slippage a lot more than I would have thought.
