Well His real job is a BMW Tech; but he build Motors. Most of his projects are for road racing, but also some 4x4 stuff and a little Marine.

Typically he's building the motor anyway; often times the vehicle isn't a) finished or b) in state. This is *typically* more convenient to him.

This is definitely mostly for racing; a good bit of which is long run I've never seen a chassis dyno that is large enough for his motors and can vary load.
I've only done work on chassis dyno's myself. I no longer have easy access to one.
As a bonus here is the blue Supra backing up to the Dyno at Hennesey last month. That's a friends Road Race Z06 on the dyno in the background, heads, cam 56x rwhp; smooth as can be.
I'll snap some pics of the engine Dyno next time I'm over.
