Clayton was the "biggie" for chasis dynos but there were others. School I 
went to had a Maxwell (if I remember right). They also had another one from 
another company. The Maxwell was an odd system. Instead the usual mechanical 
or water brake, it used a large electric motoer through a ford three speed 
tansmission to the rollers. You selected the roller speed with the 
transmission (I think it had choices of 30, 50 and 70 MPH) and then ran the 
car to that speed. Then you applied power to the motor. It had a two way 
transducer for torque so you could see parasitic loss along with horsepower 
to the rollers. The other onet hey had used a large disk brake (said to be 
off a tank) and simply measured torque applied.
