Engine Masters (2015)

Episode Overview

This week on Engine Masters, brought to you by AMSOIL, we're diving into a comparison between iron and aluminum cylinder heads to determine which one produces more power. While the lighter weight of aluminum is a clear advantage, there are important factors at play. Can aluminum's superior heat dissipation lead to increased power, or does the heat retention of an iron head enhance cylinder pressure and boost performance? The only way to answer these questions is to put them both to the test on the dyno.
