You asked and we're here to answer! On this episode of Engine Masters presented by AMSOIL, we take our small-block Chevy 383 and show, piece by piece, how much power your water pump kills. We move from an electric pump to mechanical with all kinds of cooling tricks to show you just how little it matters. We even throw on an alternator under load just to drive the point home. Engine Masters is supported by Summit Racing Equipment, Holley/MSD, Earls Vapor Guard Hose, and Mr. Gasket.
