Got the engine back on the dyno for some more testing last week. I was mostly interested in working on the oiling system. I had a new dry sump tank design to try out and I had a flow meter hooked up to the oil pump for the first time.

At 7000 rpm this engine has about 8 gallons per minute of oil flow. That is a little less than I expected given the unbushed lifter bores and the valve cover oilers. The oil pump section is only 1.0 inches wide but it doesn't have any trouble maintaining 75 psi at 8 gpm with 5w30 oil. Anyone else have any data on oil flow rates? I've never seen anything published other than the Milodon claim that their Mopar pump flows 15 gpm.

The air coming into the dyno cell was only 37 degrees so I had to add a bunch of jet size. Uncorrected power was way up given the cold air. Barometric pressure was 30.07 so it was a mineshaft air day. Altitude was -1500 ft when I looked at the gauge. Cold air and Q16 combine to make a lot of raw power.
