The Skunk2 Racing Ultra Series Stage 3 Camshafts are engineered to deliver up to 80 horsepower gains on Honda and Acura K-series engines, making them an excellent choice for high-performance applications. Designed with high-lift, racing profiles, these camshafts optimize mid-range and top-end horsepower and torque, shifting peak power higher in the RPM band for a more aggressive power delivery. The seamless VTEC crossover ensures a broad powerband and smooth operation across all RPM ranges, making them suitable for heavily modified and turbocharged engines seeking maximum power output.
Manufactured from proprietary forged tool steel cores, each camshaft is CNC ground with advanced, patent-pending profiles featuring unique lobes, increased lift, velocity, and acceleration characteristics. These features contribute to exceptional valvetrain stability, engine response, and durability. Skunk2's commitment to quality is evident through their in-house design, extensive testing, and use of cutting-edge manufacturing techniques, including cubic-boron grinding wheels, which produce hardened, wear-resistant lobes for long-lasting performance.
The Ultra Series Stage 3 Camshafts incorporate Fast Ramp and AMAX profile technology, resulting in improved throttle response and overall engine performance from idle to redline. Designed to fit a range of Honda and Acura models, including the 2002-2008 Acura RSX and 2004-2008 Acura TSX, these cams are ideal for enthusiasts looking to maximize their engine's potential. Please note that these camshafts are not CARB approved and require carb acknowledgment, making them suitable primarily for off-road or racing use.
With duration specifications of 275 degrees at 1mm lift for intake and 277 degrees for exhaust, along with valve lifts of 0.580 and 0.565 inches respectively, these camshafts deliver aggressive performance characteristics. The intake centerline is variable, allowing for fine-tuning to match specific engine setups, while the exhaust centerline is fixed at 112 degrees BTDC. Each set includes two camshafts, providing a reliable upgrade for high-output K-series engines seeking maximum horsepower and torque.
