Noise from s/c pulley?
I noticed some noise coming from the small s/c pulley, like something needed to be grease down. Only have it for about 15k mile now.
Last time at the track, my best mph was 121.75 mph, and lowest was 118 mph. Today, I ran the car after a re-tune, and the best mph I can achieve was 117.88 mph. Not sure if it's from the tuning or from the s/c? Any ideas? I'm thinking about going back to stock s/c pulley after I add the 172 mm pulley.

I spun the pulley around, and could hear the noise coming from there. It's not that loud though, but it's very noticeable on idle. I'll just go ahead and replace it with the stock pulley, just for safety.
