Product Description

Thumpr™ NSR Modular 3V Camshafts

Ford built a great car in the '05-'09 S197 Mustang, but with a little help from COMP Cams® it can sound and perform like a real "hot rod". The Thumpr™ Ford 3 Valve Cam Sets for 4.6L/5.4L Modular 3 Valve Engines deliver an aggressive “thumping” exhaust idle and generous power gains in the middle & upper rpm range. These cams will turn your naturally aspirated or blower-equipped Ford 3 valve engine into a performance machine with a minimum of installation difficulty; only requiring the addition of the COMP Cams® Cam Phaser Limiter Kit (#5449) and computer tuning. The COMP Cams® Cam Phaser Limiter Kit (#5449) safely modifies the factory variable cam timing (VCT) system allowing for the use of aggressive camshaft lobe technology without sacrificing the benefits of the VCT. Extensive testing of these new camshaft combinations has confirmed repeatable power gains of 25+ rear wheel horsepower with no sacrifices in long term durability. BIG MUTHA' THUMPR™ - Extremely rough idle, needs stroker motor and/or ported heads. Major hp gains to 6800 rpm. Best with 3.73+ gears & 2500 stall. Compatible with stock valve springs.
