Richard Holdener is fond of saying “Every cam is a turbo cam.” and he’s right. He’s right, because what he means is that if you add a turbocharger to any engine, and make boost, then it will make more power. Sure, if you are trying to build the ultimate horsepower producing engine then camshaft specs will matter, but with normal power levels that most of you are after, any good performance camshaft will be an upgrade over stock. So what happens if we swap the same camshaft into two different engines? If the cam is worth 50 horsepower on one, will it be worth the same on the other? Is there a magic camshaft that just works in any engine?
For that information, and all the details on the engines used for this test, you are going to have to watch the video below. Richard puts both engines through their paces, swaps the same camshaft into each one to see just what power gains are possible with both combinations, and then starts the dialogue with out about the results. The numbers don’t lie, but there is certainly room for questions, debates, and more so get your comments on and see if Richard addresses your remarks in a future video.
