Ran some oil flow tests to see where the air was going on my oil cooler naca as well as the new boat tail mod on the cowling. The boat tail mod is a huge winner. Flow attached all the way back. NICE! The oil cooler naca is a different story. I've got oil flow that actually goes in and then comes back out the duct! Well aint that a big clue! I've got to research way to keep that air going in and staying in. I'm sure an exit into a low pressure area would be ideal but that would be a big mod I'm not quite ready for just yet. I'll need to take care of the inlet first.
