    Default round cowling super 7 with 912 s cooling problems

    can someone help with cooling problems on a new super 7 with round cowl and 912 s engine. during ground testing with 3,000 rpm cht was 280 degress. is their any other super 7's with round cowls and 912 engines flying at this time? i feel that the air is not being pushed through the radiators and bypassing and going out the bottom out of the muffler thinking about adding fans under radiators to suck air through. please help. thanks

    Installations vary. To get a better idea of your situation, post some pictures of your installation with cowling installed and with the upper or lower part removed for clarity. Show pictures of the radiator location and any baffling, ducting or scoops you have to direct the airflow. Then maybe we can make some suggestions.
