Hi People

Finished ripping out the Mazda oil cooler and installing a new Mocal 44 row (250in3) cooler fed by a slightly larger 9in2 inlet.
I did the first test today which was simply idling for 25mins to see where the temps peaked.
Previously Oil and Water peaked at over 220F
Water still gets up there (540in3 fed by 20in2 right cheek - close to prop)  but 
Oil peaked at 176 F down ~45 F

Here are a couple of photos of the new cooler and diffuser.
