I prefer the NACA air scoop on the belly. My Long Eze has 220hp, it’s cooled with 33 square inches of inlet. Yes it can be done. It's hot in Memphis in the summer and my oil temp runs 185 to 205 degrees Fahrenheit. The hottest CHT in the climb will be 410 in cruise 350. Keep in mind I have done a lot of work dealing with cooling issues and the NACA scoop works best. If you prefer one of the others, enjoy.
