Has anyone noticed better cooling from the newer style radiator? 997-084

From the article, it sounds about the same as the old radiator? 

I’m looking for better cooling (larger radiator)

    Hi Nick,

    A larger (coolant) radiator may assist/cure your overheating problems but if you seek advice/suggestions it would be helpful to know:

    #Aircraft type

    #Cowling design (air inlets/outlets/size/location) - photos.

    #Cooling system (including oil) layout/size - photos.

    #Engine 80/100/115 hp

    I see you hail from Seattle, usually bit cooler than New South Wales. Australia. In the 12 months I have had to completely rethink/design my new Sonex cooling system (all good now).

    Many times cooling isn't about the radiator. It may be cowl air flow, Direction the radiator faces the incoming air flow or hose routing. Hose routing is usually to tight a bend in the hose which reduces the radius and slows the oil flow which raises temps. When I find a hose like this I install a spring inside the hose. Owners have said it dropped their oil temp by 15F - 20F. Some aircraft Mfg's have had this issue and modified their cowls for better airflow.

    Better cooling can be had by optimizing airflow. Get many opinions on your situation.
