You might want to evaluate the flow out of your cowling. Airflow m= any times is counterintuitive.before you start ripping  into your cowl d= etermine where the problem is. Tuft inflow and exit with stands of yarn and &= nbsp;blow through (strong Fan). You might find that no matter what your Inta= ke is like, the air dams up and will not flow appropriately.

The exit of cooling  air is as important if &n= bsp;not more important than the entrance

Air does  not always usably go from high pressure to low
