Aluminum Pulley Issue: Cold
 

Quick FYI.

I had the Unorthodox Racing pulleys installed back in December. No problems in the warm Florida weather. But back in the cold of Missouri, the pulleys let out a creaking noise at start.

This is apparently due to the crank pulley being all-aluminum. I don't know the physics, but presumably aluminum responds funny to cold.

But after a minute or so, once the pulley warms up, everything runs great and the car drives great.
