Hey does anyone know where I can find a stock sized Jackson racing supercharger pulley? I have a 3.4" right now and it's more than I'd like. I'm ok buying new or used. Know of any online shops?

I am running 4 rib right now. I'd even be happy with a 4" pulley.

I'm going to call ASP racing tomorrow and see if they can get me a 4" pulley. Get sc rpm down to 10k and running 5psi.

I calculated the drive ratio, stock on a y8 kit is 1.63. With a 4" i would be at 1.62. I'm at 1.88 right now.

My rpm calculations were with me only reving to 6500rpm. With a 4" pulley im only 100 rpm behind stock jrsc.

5 week wait for asp. Good thing it's not called ASAP. I'll just use my a6 pulley and 3 rib belt for now.

I swapped on the a6 pulley today, definitely easiest solution for me. I ditched the p/s which sure cleans up the engine bay
