Skunk2 Pro Series Honda H22A/F20B DOHC VTEC Stage 2+ Cam Shafts

Gain an extra 20-25 hp with Skunk2's Pro 2+ Camshafts, our professional line of high-lift, racing camshafts for Honda's H-series VTEC engines. Pro 2+ Camshafts are designed to optimize mid-range and top-end horsepower and torque, raising peak power 700 rpm higher than what OEM or Pro 1+ Camshafts allow for. 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. Skunk2's Pro Series Camshafts for Honda's H-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.

Product Overview

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 Pro1 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 Skunk2 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 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 designs.
• Pro 1: High Lift Street/Race cam designed to optimize mid-range and top end HP and TQ. Peak power is designed to occur at factory redline. Pro 1 cams also perform great in high-output turbo racing engines. Valvetrain upgrade required. Pro-Series valvetrain recommended.
• Pro 2: High Lift Street/Race cam designed to optimize mid-range and top end HP and TQ. Peak power is increased and power band is moved 700rpm higher than Pro 1. Pro-Series valvetrain required.
• Pro 3: Extreme Street/Race cam designed to optimize mid-range and top end HP and TQ. Peak power is increased and power band is moved 700rpm higher than Pro 2. No other high rpm racing cam can come close to the Pro 3. Pro-Series valvetrain required.
