Thumpr NSR Camshaft 09- Up Dodge 5.7/6.4L HEMI

The COMP CAMS Thumpr NSR Camshaft for 2009-and-up Dodge 5.7L and 6.4L HEMI engines is designed for automotive enthusiasts seeking enhanced street performance and a distinctive mechanical sound. This camshaft is ideal for those who appreciate a lumpier idle and aggressive valve overlap that sets modified engines apart from stock configurations.

Engineered with a specific lobe design, the Thumpr NSR camshaft maximizes overlap duration and valve lift, resulting in an audible thumping at idle. Its design focuses on optimizing ramp rates to reduce friction while ensuring smooth valve transitions. This camshaft reshapes combustion events, enhancing scavenging efficiency and intake charge velocity without sacrificing reliability.

Owners of 2009-and-newer Dodge Charger, Challenger, Magnum, and Ram models equipped with 5.7L or 6.4L HEMI V-8 engines will benefit most from this camshaft, as it provides a straightforward bolt-in performance upgrade. It is best suited for engines with stock or slightly modified intake and exhaust systems, allowing for improved performance while maintaining street drivability.
