BTR Centrifugal Supercharged Camshaft Stage 2

This new version of our Stage 2 Centrifugal camshaft makes excellent power and torque everywhere in the curve. Developed in house, we went back to the drawing board and found more power and torque even with the use of less intake duration. These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards.

E85 fuel is highly recommended. The dyno sheet below was with a LS3 short block, GMPP ported LS3 heads, BTR Trinity intake manifold, Procharger F1A supercharger. 24.5psi boost @ 7300rpm, E85 fuel.  Tested in house on BTR’s Superflow dyno. 

221/24X, .619/.617, 113 LSA
