Anyone ever used a magnetic balancer to balance a compressor wheel and shaft? These looks to be very very sensitive. There is no friction because the shaft is suspended between two magnets and the heavy part always stops at the bottom. Wondering if this is something that is common for people to do when they build their cars.

 

Um...that's some Back to the Future sh1t that probably cost a lot to have done since Hoverboards don't exist and we're Hyundai cheapo people...
