For those interested the algorithm to calculate power on a dyno, is based on the speed that the torque is produced. To clarify this a little further, power is based on how fast the work (torque) is done, and torque is based on how much work can be done. An example of this is the steam engine. It is capable of pulling massive weight, due to having much torque. But it doesn't produce much power, therefore it takes time to get it up to speed. So a car that is running a 1/4 mile is required to produce both torque and power, to obtain a fast time. It is torque that is required to get you off the line, but power to get you over it. Hopefully that makes some sense. Cheers
