I had this pan made from a solid block of aluminum. I think the block weighed about 90 lbs to start with. I haven't bolted it on yet but should get to it shortly.
I'm using a 5 stage pump and a 3 gallon tank. Not sure what the gph is on the pump, nothing to huge. If the engine is sealed up the pump will pull 15 to 20 inches of vacuum and the oil pressure stays around 75 to 80 psi hot at 7000 rpm. So right what you want.
Where can I get info on dry sump pumps. How to inspect,clearances,torque values,service parts etc. Picked up a conventional KB pump and a system 1 shaft driven pump. Mounts where the stock pump goes. A book,website? Thanks!
