Wednesday was the first flight of N37CP. Everything went well. I have now flown 5 hours since then. The only issue I have are high CHTs. During climb I see 420 on number 5, with the remaining at 400. In cruise at 3000 ft @ 75% I see 360 on the coolest and 400 on the hottest. They have slowly been coming down with time. Number 5 continues to run the hottest , with 1&2 right behind. I decided to remove the left side vertical air dam. I saw a drop of 20 deg on number 2! It did not have any noticeable affect on 4&6. My plan is to remove the dam on the right side today.
Any suggestions on number 5? It's sealed up tight. My cowl is cut even with the firewall per the plans. Any other experience with the front dams. I see that Tim Olson has his trimmed down
