Good evening.
I was wondering if someone could simply give me the lower pulley part numbers for 15%, 18% and 21.5% OD (and their accompanying manufacturers). I am about to do some modding with a dual nozzle meth set up and I cannot get a clear answer as to who makes the 18% OD lower pulley.

On a side note, what would a 18% and 21.5% OD pulley spin the stock blower at? Not looking to go much, if any, beyond the max efficiency.

Please keep in mind the car has intake, ported TB, headers and dual nozzle meth set up.

Thanks kindly in advance.
