Patrick thanks that was very informative.

I did note that they said the turkey pan is a cold air box. Also that the worse case filter costs 8.2% in restriction. If my temp assumptions were correct, I still showed a 11.1% increase from the cooler air. As they showed there are better filters. Although filter selection looks to be critical, cooler air would be a big benifit, so I guess it comes down to a question of how much the turkey pan actually drops the air temp going into the engine.

I always wondered why anyone bothered with two carbs at the 400-500 hp level. Looks like that second air cleaner is much more important than the carbs.
