Thanks=20 all =85=85

Okay=20 =85. So here=92s what I=92m taking away here.

 

Coolant=20 style heat exchanger at the oil filter location : Not currently = being used=20 in known rotary applications. Consensus is that it is not=20 sufficient.

 

Oil=20 Cooler in the radiator? I read where Tracy (in an early version) = tried=20 running a coolant coil through the oil pan.

So=20 is everyone running a separate oil cooler?

 

I=92m=20 putting this in a canard and will be using the P-51 style scoop. = I=92ve=20 bounced back and forth between that and a NACA scoop. After reading = an=20 article on the =91Meredith Effect=92 I settled on the P-51 scoop.=20

 

I=92m=20 a ways off on the engine install but I=92m trying to avoid painting = myself in=20 a corner. I should be installing my engine next summer with a little = luck.
