How does a Dyno Really Work?

I think maybe what Del is trying to say is, without a measured torque spec, you cannot figure horse power. In other words, the dyno doesn't "see" horse power, it "sees" torque and makes that conversion. So without torque, you won't have measured horse power. That much is right, because torque is what spins the dyno. If da beeotch don't spin, you ain't gonna get nuffin.
