He needed to do a baseline and the UDP test on two consecutive days at the same time of day when the weather was generally constant to be able to accurately measure the difference.
Considering the difficulty of the change. This could be planned on the same day. Then again we are talking inertia change. Just like a lightweight flywheel but at a microscopic scale. Engine will rev faster without load. That's if the parasitic drag of the equipment doesn't increase from the pulley size change. With load, nothing will change.

Hey if you are looking for most horsepower output, try running a lighter oil both in the engine and transmission. You will have way less parasitic loss and more income loss.

To be honest, I feel my boxster would benefit from a beefier flywheel looses revs too fast for my taste which makes up shifting a rev match fest(6 speed).
