I waited around 30 minutes after shutting off the engine to check the level. The dipstick seems to be pretty consistent when I use it. Every time I get an oil change, except for this time, it's at the max level inside the indented part of the stick. And whenever I check it between oil changes it's at that same level.
I suppose this could just be 5 quarts of oil in an engine that takes 4.6 quarts. But it's also possible that they put 6 quarts in.
In a spec series having 4-5% cylinder leakdown instead of 2-3% can cause the same thing (dropping several places in the pack). No one on the street would give a shit though.
More to the point - on the race track there is MUCH more opportunity for the oil to be sloshed around, what with all the serious cornering, accelerating, and braking. On the street oil sloshing just doesn't happen (save emergency situations) so it's not a concern.
If the crank was actually whipping through the oil in this situation OP would likely have detected issues already, likely including frothy oil on the dipstick.
It is not about the crank sloshing through the oil in the pan. When an engine is running at higher rpm a lot of oil is elsewhere than the pan anyways. Windage is the massive air turbulence caused by the movement of the pistons up and down that throws oil around the crankcase. The new ls7 is a dry sump system, still GM engineers developed windage holes in the webs supporting the main bearings to combat this.
Whelp, robbing your engine of 8hp on a 200hp engine will kill your fuel economy by around 5%. That can add up. Whether you care about it or not.
