I have a 1995 SC and was wondering what the stock size for the pulley on the supercharger was.

S Scott Long Registered User Dec 1, 2002 #2 I don't know the actual size but its bigger than the stock pulley on an 89-93 SC. A 5% is like a 10% on the late blowers, and a 89-93 pulley is like a 5% for you. A 10% pulley might be too much and you won't benefit from it.
