I havent seen one yet but I imagine UUC is working one up. Have you called them?

Thanks for the rec! I just talked to UUC. Rob there was super helpful.

He said the UUC is not considering developing pulley upgrades, as there is little need for such on the 1-series because:

1. the water pump is electrical;
2. not much HP to be gained from replacement pulley to power-steering;
3. it is not smart to under-drive the alternator

It sounds like you received some very good advice.
