This is the 987/981 Board -- your ad doesn't even mention those models. Does it apply to us?

Also -- please explain how your pulley improves HP and torque, and how much improvement do you claim?

I pulled the promo sheet from the wrong model, my apolgies. However, the 996/997 Lightweight crank pulley also fits all 986 and 987 applications.

Here is a quick breakdown of what the pulley does

The premise of the underdrive pulley is that it will reduce demand that the stock pulley implements on the power steering pump at high engine revs. This leads to increased longevity of the pump. The Lightweight pulley will also improve performance, throttle response all while reduces load on the engine.

There will also be a slide increase in HP and TQ.

** There are a bunch of happy users on another board. I hope that explanation helped
