Have you tried the the rpm belt?

I gotcha, my bad. Vortech doesn't offer the high traction in 3.2. 3.15 is the biggest. I have the Vortech bearings in the SC, so I'm not ready to overspin for the moon quite yet haha. Long-term, if I stay supercharged, I want to shift to a bigger blower like the Vortech V-7 JT-B that can spin faster and give more flow. If the SC fails, I'll likely send it to 928 for bearings but keep the Si impeller unless the 928 impeller flows better.
RPM belts are on the way. The last one I had got eaten pretty quickly when the pulley failed.
