Greetings,
 
I made it out for a few laps around the field today.  I had the lower cowl exit opening blocked off, so all the air had to exit the cheeks.  Happily, I didn't notice any difference in the temps.  Still 180/180.  I probably need to pull the thermostat out to see what the water really wants to do.  The next step will be to start choking off the huge inlet to the radiator/oil cooler.  
 
One interesting thing that I noticed was how hot the left side of the fuselage was.  There's clearly more hot air coming out the cheek than before.  It's quite likely that I didn't have enough left rudder during climb since I don't recall looking at the ball.  Naturally, my mind starts to thing of how welcome this heat will be in the winter.  Then I think of how to control it.  Let's see, right rudder heats the left side, and left rudder doesn't :-) 
 
Finally, I adjusted my relief valve to only allow 5 psi of boost.  That means that I can use full throttle, and 5 psi at the same time finally.  The result- zoom zoom!  The RV-8 never pulled like this :-)  Boy do I need a VSI (or an EM-2).
 
Cheers,
Rusty  
 
PS- Hey Toddzan, me want more flight test reports :-)
