Hello Paul,

What is the approximate oil flow rate in gal/min or Liters/min
for a 13b assuming good oil pump and AN-10 hoses?

Batmol have curves for their coolers but one must know
the flow rate to get cooling capacity.

Thanks,

JP

As I recall  it is about 30 GPM but I'll check all
the manuals when I get home in a few days.

Answer ~10-15G/minute.
From the 85 Technical data -
oil - 7L/min @1000rpm
coolant - 150-160L/min @6500rpm

IIRC, Al Gietzen? measured something like 15gallons per minute with a
20B pump @6k rpm @ 100psi.
One of the 20B owners may be able to confirm if the 20B pump has the
additional 3rd gen oil pump inlets on the lower side.
I have heard other dyno oil flow rates of 12-16GPM for 13B's.
IIRC, Lynn posted ~16GPM @6k rpm for a Mistral engine with oil mods.(no
oil pickup bug screen, radiused inlet, cleaned up internal passages,
straight weight anti-foaming oil, ...)

Flow rates will, of course, depend on pump type(NA/T/3rdgen), oil type,
temperatures, filter, plumbing, mods...
