I'm thinking of up grading to the 181mm pulley, if i do i'll sell you mine. For your info i already tried stacked pulleys, i ran a midsize code 3 68mm s/c pulley and a 178mm crank pulley which gives you 15705 rpm at the supercharger.705 more rpm than a 185mm crank pulley with a 74mm oem s/c pulley. They say 15000 rpm should be max operating range for our s/c. My biggest concern was my a/f ratio. i got up to 20 psi and according to my datalogger voltage reading at b1/s1(bank 1 sensor 1)i was running way to lean so i shut her down and reinstalled the oem s/c pulley. your best bet is to have your oem s/c pulley machined to at least 70mm (tvt does it) and you might get away with running stacked. If you try to stack a 65mm s/c pulley with a 178mm crank i think your asking for a/f problems plus you would be at 16430 rpm at the s/c. I know there's
so called fixes for the leaning out problems but nothing that i know of that been 100 %proven.Just my 2 cents worth. ILLCYA P.S. APROX.5000 MI
ON MY 178 CRANK PULLEY.
