The Comp Cams XFI SPR Stage 2 Blower Cams are a great choice for engines with a built bottom end and a centrifugal supercharger. These Camshafts offer a great increase mid to upper RPM horsepower. Shift points will be around 6900 - 7000 RPM. Suggested for use with an upgraded Intake Manifold and ported Cylinder Heads. 3.73 - 4.10 gears and 3000 - 3400 stall suggested. Custom tuning required. Upgraded Valve Springs and Phaser limiters required. We normally run lockouts with these camshafts and suggest an intake centerline of 109 when using lockouts.
