skunk2 Pro-Series Cams
Skunk2 Pro-Series professional line of racing cams are designed to optimize mid-range and top-end HP and TQ; and significantly reduce lap times. VTEC crossover is seamless allowing for the broadest possible powerband. No other line of racing cams can even come close to the performance of the Pro-Series line. Pro-Series patent pending camshaft profiles dramatically improve horsepower, torque, engine response, and valvetrain stability. The Pro 1 cam is the BEST ALL-AROUND STREET CAM and dramatically improves horsepower, torque, engine response, and valvetrain stability. Pro-Series camshafts feature a seamless crossover between low and high speed cam lobes with patent pending profiles defined by specific lobe shapes as well as specific characteristics of lift, velocity, and acceleration. Pro-Series cams are all designed utilizing Skunk2 s proprietary Fast Ramp Technology and Amax Technology. Use of these two technologies allows us to design aggressive camshaft profiles that maximize area under the valve lift curve without adversely affecting valvetrain stability or reliability. In fact, the use of Fast Ramp and Amax Technologies actually makes Pro-Series camshafts more stable and less prone to spring surge at high rpms. Pro-Series camshafts also feature our newly revised camshaft blanks that have increased torsional strength, improved durability characteristics, and reduced frictional effects; all of which are the reasons why Pro-Series camshafts are superior to all other cams. Pro-Series camshafts are available in Pro 1, Pro 2, and Pro 3
Stage I: Stage I profiles are designed to offer the widest possible powerband and be compatible with factory valvetrain components. These camshafts are designed to retain stock idle and are currently CARB EO-pending. Upgrading to Skunk2 Racing valve springs is recommended. Stage I profiles are relatively easy to tune for maximum power output.
Stage II: Stage II profiles are more aggressive than Stage I profiles, and are designed for modified engines operating at higher rev ranges. Upgrading to Skunk2 Racing valvetrain components is required for proper operation. Stock idle and emission characteristics may be slightly compromised, but fair-to-good driveability allows them to still be used on dual-purpose vehicles. Proper tuning, an upgraded intake system, and an exhaust system are required in order to maximize the potential of these camshafts. Do not use oversized valves.
Stage III: Stage III profiles are designed for purpose-built race engines with high-rpm capabilities only! Upgrading to Skunk2 Racing valvetrain components and extensive engine work is required for the proper functioning of these camshafts. Compression and engine flow must also be significantly increased. Stage III camshafts should be installed and tuned by professional engine builders only! Do not use oversized valves.
Turbo: Turbo profiles are designed for engines with forced induction. Aggressive lift and valve opening/closing motions allow these cams to maximize power with a minimum amount of overlap. Each profile is designed with extensive input from the top racers in the sport compact industry.
- **VALVETRAIN UPGRADE RECOMMENDED
- Pro Series: Pro Series valve springs recommended for Pro-Series applications!
