Mild lope at idle, excellent daily driver camshaft for Trucks and SUVs. Powerband: 1200rpm - 5600rpm High Lift Cams For Aluminum HeadsĨ00SRC high lift supercharger camshaft, must use Raylar forged pistons. Powerband: 1400rpm - 5200rpmĦ50SRC low lift supercharger camshaft for stock cylinder heads. Best for towing applications under 8000lbs. Best for daily towing emissions compliant Truck / RV use under 8000lbs. Cylinder Head Flow Comparison Supercharger Camshafts Low Lift Cams For Stock Cast Iron Heads We’ve included the Dart Iron Eagle 8.1L cylinder head in both 4.5 and 4.26 bores for comparison. Below are flow numbers for our standard Raylar CNC heads and our special-order CNC Extreme cylinder heads. Raylar big block Chevy / GMC cylinder heads out flow every 8.1L cylinder head on the market. Our combustion chambers promote a more even burn, increasing engine efficiency, fuel mileage, improving driveability and reducing detonation in supercharged applications. We've gone to great lengths to make improvements over the stock cast iron Vortec cylinder head. We recommend forged rotating assemblies for boost over 5 PSI. We routinely see engines with cracked, chipped and even shattered pistons which result in catastrophic engine damage. The stock Vortec 8.1L cast pistons are not designed to withstand the forces of extreme endurance use, especially in supercharged applications. 8.1L Computer Tuning Vortec 8100 / 8.1L 496cid Pistons Check out our tuner list to find a tuner in your area. We don't offer computer tuning, but we've met lots of good people who do.

The 2.9L supercharger kit makes 8lbs of boost and is good for 600hp / 690ft-lbs with stock cylinder heads, 202 camshaft and a forged rotating assembly. Continued rotation progressively reduces the space occupied by the air causing compression.ĭischarge Phase - Compression continues until the inner-lobe space becomes exposed to the discharge port at the bottom of the supercharger, forcing air into the manifold. The air moves forward through the supercharger case and filling the inner-lobe space between adjacent lobes.Ĭompression Phase - As the rotors mesh, the air is trapped between the rotors and the casing. As the lobes of each rotor travel past each inlet port, air is trapped between consecutive lobes and the cylindrical casing. Inlet Phase – The male and female rotors rotate counter to each other.
