HEMI VVT Stage 3 Camshaft

The BTR HEMI VVT Stage 3 Camshaft is engineered by Brian Tooley Racing for Gen III 2009+ Hemi engines, offering a significant performance upgrade for naturally aspirated applications. This camshaft boasts a 220 intake duration at 0.050 lift and 23X exhaust duration at 0.050 lift, with a 112 LSA. The valve lift measures .587" on the intake and .586" on the exhaust, with an intake lobe lift of .356" and an exhaust lobe lift of .355". The specified RPM operating range is 2100-7100, and it is designed to provide a noticeable rumble at idle, rated 5/10 on the chop scale. Brian Tooley Racing states that this 'Stage 3' grind is meticulously crafted in-house, with lobes balanced for performance and stability, validated through rigorous spintron and dyno testing. Expected gains from a cam swap are cited as 85 horsepower and 12 ft-lbs of torque, along with an additional 1600 RPM of operating range. Drivability is maintained when paired with an aftermarket torque converter. The product is made in the USA. Installation of this camshaft requires specific supporting modifications and components. A VVT Limiter (BTR-VVT-HEMI-4CAM) is mandatory and included with the camshaft, though the installation tool (BTR-VVT-Hemi-Tool) may need to be purchased separately. BTR recommends specific aftermarket valve springs such as SK017, SK017/TS, or SP021-16 due to the high valve lift and increased RPM potential. Non-MDS lifters or an MDS conversion are also required. Professional engine tuning with attention to VVT control is imperative for optimal performance.
