Curtis C96 overloads when the pressure reached

I have a Curtis C96 Compressor on an 80 gal tank. It had a 5HP 3 Phase motor which was removed when I got it. I installed a new 5 HP Single Phase motor and it overloads when the pressure reached 100 PSI. Do I need more HP in a Single Phase to run this beast? If so, how many ponies do I need?

Depends.

Probably enough power, mis-delivered.

What pulley sizes and motor RPMs you got?

What happens when it "overloads"?

When swapping motors, the main thing to check for is the RPM of the replacement motor versus the original. Most 5 HP single phase motors are 3600 RPM because of the current draw. This compressor should not run more than 800 RPM at the top end. If the old motor was 1800 and the new one is 3600, you are probably overspeeding the compressor and causing the motor to overload.
Just a thought.
