Decided to replace the 1/2hp compressor with a rotarty the other night, now running 1hp first stage and a ½-3/4hp rotary on the second stage. R290 first stage 1150 second stage. First charge for the night she hit -105c and loaded with 312w doing -91c. With the bigger compressor my static charge second stage went from 150psi to 280psi so lets hope she handles quad core. Will do final insulation tonight and clean up the wiring, then do final tunning on the quad core
Got to love the smoke that comes off the accumulator when you first start the second stage.
