The BTR Centrifugal Supercharged Camshaft Stage 2 (BTR-CENTRISTAGE2) is a hydraulic roller camshaft for GM LS-Series engines running centrifugal-style superchargers. It was developed to deliver excellent power and torque throughout the curve, even with less intake duration than earlier BTR centrifugal cams.
- Part Number: BTR-CENTRISTAGE2
- Application: GM LS-Series, Centrifugal Supercharged
- Camshaft Style: Hydraulic Roller
- Intake Lift: 0.619 in / Exhaust Lift: 0.617 in
- Intake Duration @ .050": 221°
- Lobe Separation Angle (LSA): 113°
- RPM Range: 3600-7300 RPM
BTR highly recommends running E85 fuel with this camshaft. BTR's own dyno testing was performed on an LS3 short block with GMPP-ported LS3 heads, a BTR Trinity intake manifold, and a Procharger F1A supercharger at 24.5 psi of boost at 7300 RPM on E85 fuel, tested in-house on BTR's Superflow dyno.
