Perry,

Although I'm always interested in your progress, I didn't realise you were
trying to use a 12A oil cooler on a 13B.

Previous discussions suggested they weren't up to the task, but I assumed
you thought it would be OK with reduced RPM?

Just imagine how much cooler a 12A will run with a 13B cooler - I will have
to remember that!!.

That duct looks like a fighter jet intake, so pulling in the boundary layer
doesn't seem to affect it ?

I would not say that George :)

BTW I am not sure that is a 12A oil cooler. My 83 RX7 had a water to oil cooler
under the filter.

So does a couple of my 12A's.
