1 thing you can do is run full-synthetic fuel in the engine. I noticed immediately upon switching my 90SP from Power Master caster oil based fuel to Cool Power 10% full synthetic fuel that the engine runs alot cooler. Also you need to direct the airflow from the Mustang's air-inlet (below the spinner) upwards at the engine's cooling fins, and allow for a large enough opening on the bottom of the engine cowling for air to escape from in there adaquately.
