COMP Cams Camshaft Set F50Cy Nsr-Bl3H-1

If you're building a high-performance 2011-2014 Ford F-150 with a 5.0L Coyote engine, this COMP Cams XFI NSR Blower Hydraulic Roller Camshaft Set is designed for maximum effort street and strip applications. These cams are specifically chosen when you're pushing higher boost levels and aiming for high RPM operation in a modified engine. They are a hydraulic roller type, meaning they use roller followers to reduce friction compared to flat tappet designs, which is crucial for the demands of boosted engines.

The 'NSR' in the name stands for 'No Springs Required,' which is a notable feature that simplifies installation by allowing you to use your existing valve springs, provided they meet the specifications for this camshaft. The camshaft grind itself is a 236/243 duration with a 115-degree lobe separation angle, optimized for forced induction setups. This profile helps to manage the increased cylinder pressures and airflow associated with turbochargers or superchargers, making it a solid choice for serious engine builds.

Because these are max-effort cams for modified engines, they require custom ECU programming to properly tune the fuel and ignition timing for optimal performance and engine health. Additionally, for applications running high boost or aiming for race-level performance, you'll need to install a cam phaser limiter kit, such as COMP Cams part #5493, or an optional cam phaser lock kit, part #5492. This ensures the cam timing remains consistent at high RPMs and under heavy load. Please note that this camshaft set is not CARB approved and cannot be shipped to California.
