Greetings,
I'm still having some high oil temps, though the = cooler weather is allowing me to get by for now.  I was thinking of try= ing to apply some of the pressure recovery lessons that Ed tried to teach us= .  It seemed to work pretty darned well with my radiator cores, so I fi= gure I should give it a shot for the oil cooler core as well.  
Attached is a very crude drawing of the cross sec= tion of my oil scoop.  The top flat line is the evap core, and the vert= ical line on the right side is the inlet.  The top drawing is the curre= nt inside shape of the scoop.  As you can see, it isn't so great.  = ;The bottom drawing is the proposed inside shape.  Anyone want to wager= on whether this will help?  As far as fiberglass goes, it would be a f= airly painless experiment.  Think it's worth trying?
Thanks,
Rusty (Sir fiberglass hater)

The bottom one looks much better in my opinion. Also make sure the air has = good unobstructed exit path.
