I am still testing our 4" pulley in real world conditions to see how it effects the operation of the charging, power steering and A/C subsystems. Its the smallest pulley on the market and so far has out performed every other I have tested back to back in the performance category.
I have not added them to our site yet because they haven't proven themselves thoroughly enough as of yet. I hope to have them on line by the beginning of the new year.
I have almost 8K on the test pulley in my 996 and 14K on the unit in the Boxster test car.. I want to see how they perform in cooler weather.
