ENGINE OIL FLOW Question?
 

Hello , just wondering how many gallons per hour does the stock oil pump & STD regulators in a 13b cosmo engile flow at a max of 9000RPM.

Does anyone have an idea of the drainback rate of oil to the pan???

up!

This information is in the service manual.

As far as how much flows through the engine under pressure, bearing clearances, oil viscosity, and oil temp play a LARGE role in this. Thicker oil, cooler oil, and tighter clearances mean less oil flowing through the bearings, and therefore more going through the regulator(s).
