Weird.. This has been together for 8 years making up to 1bar of boost (that's 14.5 barley corns for you americans) and it's been fine. I think it just came loose.

How much boost were you running through your blitz?

HA! I love Matt Parker!

No more than 6 or 7 lbs, the Ogura compressor (TX-07) is only about 700cc/rev. The real damage was done by the magnetic clutch pulley turning on and off because there's no auto-tensioner to absorb the sudden change of tension on the belt. Here's a video of a high-performance car under acceleration that has one: https://youtu.be/5NnMuyifPA4
