Is this what you read?
Conventional oil pumps shut off oil to the crankshaft at idle, and do not start delivery of oil until 1900 RPM.

Stumbled upon it by accident
Nice USP, but not really... accurate imo.

TP builds some Really... Really good Stuff... But, I suspect they mean 900 RPM.. Oil to the bottom end only gets there after the lifters are Pumped Up, and the top end is lubed.. ie some pressure, or resistance of flow to the top end, results in oiling the Bottom end..
