today i finished 1st Stage + oil separator.... some pics
1st Stage Charge with R502

Oil Separator


1st stage running...




1st stage Pressure @ 29.5c ambient (10ingh low/190psi high)


temp: -45c Outlet HX and -42c 6" from accumulator


dont have the pic but the static pressure is arround 150psi @ 29.5c.... a bit too high/overcharged i think. now i leak testing it with 150psi. hopefully no leak.
