Not very well. I was using the factory NACA. I had hoped, unwisely that it would push enough air through the heat exchangers to do the job. Alas, no joy. I wasn't surprised but I wanted to give it a shot. I even modified the NACA's with some baffles but
still no go.
I am currently doing as I likely should have already done and placing the rad and oil cooler under the engine with a big ol' ram scoop. Depending on testing I will make the scoop smaller if warranted.
I moved the a/c condenser and turbo intercooler to the front of the engine (where the rad/oil cooler was) to be fed from the top NACA. Those items are not as critical and I suspect the NACA's will handle their need.
We shall see.

Chris,
How does cooling air get to your heat exchangers? Do you have any pictures of your install?

I want to but I am having some serious cooling issues on high speed taxi, up to over 250 degrees for a few minutes (yikes). I tried something with
modified NACA's based on Velocity Inc reducing cooling issues when they changed from armpit scoops to top NACA's, however, that is not working so I am going to a more direct ram air with a P-51 scoop. I hope to start the conversion later today. The process
may have intimidated me years ago, but, hey, the Gov'ment says I be a "Repairman" ;-)

Are you ready to take advantage of that transition training? When is the first flight? :>)

It's a kewl plane. I got to see it when I was at the factory last month for transition training.

This thing is just begging for two 13B or Renesis Rotary engines !!..........................<:)
