I retrofit that same HF compressor head onto my compressor about 12 years ago. It's a good unit. I did the math to get the speed close to it's rated max with my pulleys, so that part is good. The motor is a high mileage imported "5 HP" 230V/1PH, and it is definitely the weak link. Startup is fine, but as the pressure climbs the motor overheats and trips the thermal breaker on the motor after running for a while (30 mins continuous, depending on weather). I would recommend buying a little more power. It seems the 5 HP rating for the head means a real 5 HP on the shaft, because my motor simply falls short of doing what it should.
