And this kit already has the impeller upgrade, correct? Or is it just upgraded Si bell housing? |
I can answer a couple of your questions. I've got bad belt slippage on the jackshaft pulley, sc side and I do have a sur grip pulley to put on it when my sc comes back from 928. My sc pulley is a high traction from vortech and I had no belt slippage on that one. The 928 pulley is really gritty, I can't imagine I'll have any slippage with it.
Topgunz's kit comes with the v3 Si supercharger, it has the Si impeller which is an upgrade from the Sci.
