Okay, I have a Chinese Tuxing compressor, supposedly 4500 psi. After my tank was pressurized to about 120 bar (1200 psi or so) with the Tuxing, the compressor started tripping its on-board circuit breaker after about every 15 minutes. And this with me managing coolant temps below 58 °C by manual water exchange, so no good. Rewind back to 1980. I had a 1970 VW Beetle at the time. The air-cooled Beetles had a fan shroud that blew fresh air over the cylinder heads for cooling, but the fan also blew into attached hoses that flowed fresh air over the exhaust manifolds, that could then be routed to the interior. That was the Beetle's heating system. Exhaust manifolds + air = heat.One of the tuning mods at the time (and still today) for the Beetle was to block off the heater hose outlets on the fan shroud. This is the part that is interesting. One might think that blocking off the heater air outlets (two, one for each cylinder head) would produce a greater load on the engine (blowing against a brick wall). In fact, it's the opposite. Blocking the outlets means the blower is doing LESS WORK (moving less air), and that reduces the engine load. This can all be confirmed by turning on your hair dryer and covering the outlet with your hand. It will be doing less work and it WILL go faster.So, to summarize, I will crank down my tank valve until the compressor is doing less work and will not hit the circuit breaker. That is my story and I am sticking to it. Carry on.
