GET MORE TOP-END GAINS

Camshafts are a great way to not only maximize the potential of your turbocharger but to get more top-end horsepower gains out of your engine. Because these have a 280-degree duration, they are going to be more aggressive in terms of extending your RPMs as well. Upgraded valve springs and retainers are required to run this aggressive of a camshaft, as well as a proper tune.
