I lost a bit of power, but, the trade off is worth it. I lost 10hp/3-5tq from my last dyno, but my cat was also clogged. I will dyno again soon, with a new cat, for better numbers.
I can't believe you are worried about a little bit of increased weight on one end of the crankshaft when there's a flywheel on the other end. It's the flywheel that governs the rotational inertia of the crank (and hence engine acceleration). The flywheel's combination of high weight and large radius leads to a large moment of inertia. The pulley's effect on engine acceleration is minimal, if not completely lost.
Engineers out there, do the math and you will see what I mean.
