So, what do you all think?
I am leaning towards installing 3/4 NPT fittings, or may just drill and tap for 3/4 inch thread and use an aluminum washer...
Since I have no way to know the flow rate, the safest thing is to hook it up in parallel, that way flow rate is less of an issue (even if flow were ZERO, it wouldn't harm the motor... it just wouldn't cool any...)...
Its pretty neat that this is 1/10 the price of a name brand cooler...
Definitely worth more experimenting

.
Actually I just had a bright idea

. One could easily just place an AN fitting on either end, and get rid of the baffle. This would double the flow, as oil would only go through one end and out the other... HMMMM. May need to cut off the end caps
