I don't have this item but curious about this 3.8 supercharger pulley compatible with ZZP modular pulley system I seen something on youtube?
What is it ? what does it do?

Thanks

Modular pulley system is a press on flange for the supercharger that allows you to exchange pulleys quickly. 5 bolts and a quick swap.
