Power Adder Series

Looking for the ugly, nasty motors that separate the boys from the men? The Power Adder Series will let you add a supercharger, turbocharger, or nitrous. You’ll start with an aftermarket block and a substantially upgraded rotating assembly, heavy-duty forged pistons, and an array of camshaft and cylinder head options. Other parts vary by build and application.
