We all know the importance of cylinder heads, induction systems, camshaft selection, compression, and other major factors when it comes to making real horsepower out of your engine. Well, what about the silent killers that rob horsepower while simply doing their job. Things like fans, alternators, water pumps, and even your humble oil pan. These may not be the make or break between a lazy dog of an engine and a real hardcore screamer but they all have a role in making your engine work its best or leave something to be desired.
In this compilation video made with pieces of different episodes of Engine Masters you’ll see Freiburger, Brule, and Dulcich test stuff on the dyno at Westech and take a hard and fast look at how these “little” things can subtract from your stable or ponies.
Maybe this stuff is too small to matter to most hot rodders but for racers where tenths of a second count it could be the difference between winning and losing. Outside of the mechanics of the whole thing it is pretty neat to see, in real testing, what’s good and what needs to be avoided. The shocking things may not be the parts themselves but rather their potential performance cost. Watch!
