So, whats the differance generally between a Bosch, a Mainline, Dyno Dynamics, and whatever the hub dyno is called? How much do you loose in the driveline? 50hp? 37kw?

which reads lowest? which reads highest?

Thread could answer alot of common questions relating to dyno's and cross comparisons, we all know that really you should stick to one dyno to do direct comparisons but I want to know weather 230kw at the hubs will get 200kw atw on a mainline....for example.

Historically I have looked at one kw dyno reading, found a car that has done similar terminal speeds over the 1/4 mile, considered the weight of the car and then looked at that cars kw dyno reading to get a bit of a line....

Any other clues?
