Hydro Pulley (waterpump pulley)?
Anyone have one of these? If so what kind of performance differences are you noticing?

I have the water pump pulley and it is much lighter than the stock,
minimally noticeable performance increase but when you add it all together it makes a w worthwhile difference.
Physics tells you that it will deliver more hp to your back wheels but not much.
just whatever it takes to spin the 1 lb that was lost by replacing the water pump pulley.

It's a very cool looking piece of hardware; I also dig the potential for decreased rotational inertia! Any piece where you can essentially shed pounds with virutally no consequence is awesome.

Well,
I have to say that the install was very simple, about 25 minutes with the removal of the stock airbox - If you have an Injen or AEM it should take you about 10 minutes.
Very nice product and very well made, I had purchased this from a board member and it came without instructions so I called the manufacturing company http://www.proautosportsinc.com/home.htm
and they gave me the information I needed ( torque specs ) without question - Great customer support !
As far as the performance, It's what I expected a lighter pulley should do, Slightly noticeable difference in acceleration at least that was my impression.... Anything you do to reduce the weight is good in my book and this piece is light!
I don't regret purchasing it at all and I will consider a crank pulley when they produce one.
