Also, I just looked at his setup, and the physical layout will not work on our engines. He mounted the supercharger in place of the secondary air pump, our secondary air pump is electronic and mounted on the intake manifold. So the placing of the supercharger that he used will not work for us. And as a side note....his belt alignment is off and will cause reliability issues. More than likely due to the mounting bracket flexing under load. You can look at his belt in his pics and see that it's pulling funny and causing it to wear unevenly.
