I was watching horsepower tv on the sports channel and they dyno'd an engine that wasnt in the car. this is a first for me. would this greatly be a different number then in the car?
thanks

it reads the power from the flywheel. iirc

Yea, alot higher number, they basically just test the engine to see what power and torque it puts out on its own... once in the car, you have a much lower reading because you have to send the power through the transmission into the axles to the wheels to the ground and causes a drag on the engine... when they do engine dynos, they can dyno it for both in car and out car tests, with the in car being, they make the dyno act as if it has a tranny, axles and wheels and is heavier to turn....
