Belt rubbing on supercharger cooling pump
Not sure why this is happening, I have a larger pulley/ATI balancer which reduced clearance some but also noticed that if I grab the pump and pull it upwards there’s some give to it even though the mounting bolts are tight. You can see some green on the pump mounting bracket where it is rubbing:

Maynbe wrong belt size? If it's got a lot of slack might be enough to smack on hard accel or decel

I recall a similar issue... But I think it was my fault, and didn't seat the HX pump in the cradle properly. So I ended up using some large black zip ties to hold it in place, so any movement in the belt / flexible HX mounts would prevent contact. Worked like a charm.

Well the zip ties didn’t prevent the belt from rubbing through the top of the intercooler pump and springing a leak. Apparently the belt is stretching and flapping enough to hit the pump. Removed the pump today and will order a replacement tomorrow. Not sure what to do to keep it from happening again.

Something has to be out of tolerance? I have a similar issue (still do), where the adapter plate on my Soler throttle body to the supercharger snout makes the throttle body protrude out just enough that it rubs the black plastic cover on the throttle body electronics. I had a friend make me a piece of stainless that fits around that area. It's kind of like a "L" shape and the throttle body bolt holds it in place. Now the belt rubbing is over a smooth stainless steal surface vs cutting into the plastic of the throttle body and fraying the inside of the belts edge. This reminds me, Soler owes me a different adapter plate! I need to remind them of this! Good luck!

When I replaced the pump I found an easy solution. I bent the bracket forward slightly so that the pump was not right below the belt. So far so good.
