Gain an extra 15-20 hp with Skunk2’s Pro 1+ Camshafts, our professional line of high-lift, racing camshafts for Honda’s B-series VTEC engines. Pro 1+ Camshafts are designed to optimize mid-range and top-end horsepower and torque, with peak power realized at the factory redline. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible. No other line of racing camshafts even comes close to Skunk2’s Pro Series. What's more, Pro 1+ Camshafts are also the perfect addition to any high-output, turbocharged engine.

Skunk2’s Pro Series Camshafts for Honda’s B-series engines dramatically increase both horsepower and torque yet retain complete valvetrain stability and exceptional engine response. Ideal for heavily modified engines, Pro Series Camshafts are manufactured from proprietary, high-quality cores, are CNC ground, and feature patent-pending profiles with unique lobe shapes and revolutionary lift, velocity, and acceleration characteristics.

Skunk2 camshafts deliver unparalleled power as a result of continual, extensive development and testing. By utilizing advanced manufacturing techniques and the latest computerized simulation and modeling equipment, Skunk2 camshafts are able to deliver maximum power across the entire powerband. Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance. Each camshaft is manufactured of newly revised chill-cast, billet camshaft blanks that have increased torsional strength, improved durability characteristics, and reduced frictional effects. All Skunk2 camshafts are ground to exact specifications using state-of-the-art CNC cam grinding machines equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces..

Skunk2’s Pro Series Camshafts also feature Fast Ramp and AMAX profile technology, which increases overall performance and results in unmatched response from idle to redline. AMAX technology simply maximizes the area under the lift curve but without compromising reliability or valvetrain stability. Skunk2’s profiles feature more duration than competitors’ at lifts above 1mm, resulting in greater efficiency and more power. And thanks to Fast Ramp, the same technology used in Formula One racing, seat timing is reduced, which results in additional cylinder pressure and more torque but without compromising valvetrain longevity.

Skunk2 camshafts designs are the direct result of our years of drag racing and road racing efforts. In addition to each Skunk2 project car and race vehicle, the world’s top road racing and drag racing teams have relied on Skunk2 camshafts for years.p>

Explanation for the various stages:
- Stage 1: Street/Race cam designed for stock engines with bolt-on modifications. Also good for supercharged applications and aggressive turbo applications. Upgraded valvetrain recommended, but not required. *CARB Approved.
- Stage 2: Street/Race cam designed for engine with free-flowing intake and exhaust tracts, increased compression, and upgraded valvetrain.
- Stage 3: Street/Race cam designed for engines that require the top-end power to carry into higher rpms than what is possible with Stage2 cams.
- Turbo 1: Street Turbo cam designed for lower boost, low rpm levels 5-10 psi. Ideal for basic street legal turbo kits.
- Turbo 2: Street/Race Turbo cam designed for medium boost levels 10+ psi and slightly higher rpms. Ideal for custom turbo applications and supercharged applications.
