Default Here is what worked for me

1) Completely removed the air dams in front of the #1 and #2 cylinders.

2) Sealed every hole I could find around all of the baffles, including the inter-cylinder baffles. Used RTV red.

3) Adjusted the gap seal between the baffles and the cowl top so that there was very little leakage there. I used RTV red in strategic places on the baffles and a few places on the cowl.

4) Finally added an Anti-Splat-Aero cowl flap to the passengers side of the lower cowl unit positioned on the vertical surface.

Now I can climb through 8000 ft on a hot day at 1200 ft/min and stay below 385 deg. F.
