Time (seconds) to oil pressure is immaterial. For example, it doesn't matter to the bearings if your deuce sits for 2 or 3 years without oil pressure. What matters to the engine is crankshaft revolutions until oil pressure. Because the oil pump is geared to the crankshaft, and is of the...

That is exactly correct. The oil pump pumps the same amount of oil per crankshaft revolution at 100rpm as it does at 2600rpm... plus/minus a little for pump leakage. The bearing load increases drastically over that same rpm range. You do not want to be hammering poorly oiled bearings at 2000+...

I think I can see why you have torn down lots of engines. That has to be the worst advice I have seen in a long while. Faster is when the bearings are under the greatest stress. It's the worst time for them to be without oil. Let it idle. -Chuck
