Re: [AirVW] Oil filter on oil sump plate?
- Good point!
I've been doing some research along these lines and found that in our
RPM range (3500), the gallons per minute is somewhere around 3 g/m, the
input side pressure is around -3 psi. Input cavitation in hot oil occurs
somewhere around -14 psi. Seems like lots of margin there.
Next, I'll need to know how "FreeFlowing" an oil filter is... I guess
I've got a way to go before I know if it can work or not. It's a learning
exercise, I didn't even know what input cavitation was before I started...
