Like a lot of RV owners I am having trouble with a hot-running engine, high oil temps, and high CHTs. I can keep the oil to about 200-210F in cruise but during climb, circuits, slow flight etc.. it can get up to 230F pretty quickly and has redlined before now.
After reading a lot I think I am going to try the simplest solution of opening the bottom cowling a little to give more airflow over the cylinders. I know others have tried this with some success.
I would love to hear back from those who have opened the lower cowling a bit, especially regarding how much they have cut out, with photos if possible.
Many Thanks
Oh - I have an RV7a with a CS prop and 180hp carbed Lycoming.
