From the factory an engine is usually equipped with a camshaft that sacrifices low-end torque and top end power to focus on smooth idle and fuel economy, neither of which are a primary concern in high performance or race applications. Upgrading your camshaft is the single most effective way to change how your engine behaves throughout the RPM range. The camshaft controls the duration, lift, and overlap of the intake and exhaust valves opening.
Tomeis Camshafts are designed to help your engine flow more air faster, the basic recipe for Horsepower and Torque. This increased volume is achieved by increasing how long the valves stay open open, how far they open, and their overlap. Selecting the proper camshaft for your particular wants, needs, and engine set up allows you to maximize Torque and Horsepower in whatever range is most beneficial for your particular driving or racing style.
Tomei Camshafts undergo a vigorous research and development process to maximize horsepower and reliability. All Tomei Camshafts are CNC machined to guarantee a precise fit and proper valve lift/duration.
Tomei had spent extensive time with R&D on these camshafts, with various testing on all type of combinations and prototypes. So many in fact, that by the time they had released these cams, the 4B11 & EVO 10 had already been on the market for 2 years.
With materials especially selected for this engine, special profile designs and manufacturing process just specifically for this engine. All EVO 10 customers can rest assured that satisfaction will be delivered with these camshafts.
