I did have my water pump shred it’s impellers. Luckily this happened coming off track on the cool down lap so I didn’t over heat the head. Word to the wise, don’t use the oem plastic impeller water pump. Buy a metal impeller aftermarket pump made for the E46M and use a freeze plug to plug the P side hole for the their overflow pipe.
I also installed a Motorsport T-stat that opens at 155f. Car now runs crazy cool. With 80f ambient after a 30 minute hard charging session my water did not get over 175f.
