Mustang Cylinder Heads - Bolt On A Pair
|
To corroborate the dyno and flow bench findings, Westech fitted the air hat atop the Mighty Demon for a couple of runs with each cylinder head. The air vane costs next to nothing power-wise-about 2 hp-but the power figures in this article are without the air hat in place. The airflow figures from the dyno to flow bench made sense. Air consumption for both heads peaked at 612 cfm, and the curves correspond to the power curves. Having the airflow and power curves the same shape supports the idea that the small performance difference in the heads is due to the change in airflow, and not a tuning factor such as ignition timing.
