Once everything was measured...
Once everything was measured and bolted in place (windage tray nuts are 36 lb-ft), we installed the Milodon oil pan using the supplied pan gaskets and mounting hardware.
As expected, the majority of the power gains occurred at the top of the rev range, where windage was most prevalent. According to the Milodon website, crank-throw speed (at the tip) exceeds 300 mph at 6,000 rpm. If you have ever stuck your hand out the window of a moving car at 30-40 mph, you can imagine the resistance offered by the oil and vapor at nearly 10 times that speed.
Eliminating or greatly reducing windage with an oiling system upgrade is not quite as visible as a new intake or a fancy set of heads, but it is one of those hidden-horsepower tricks that can sneak you past the competition or get you some extra miles from your performance engine.
