Gain an extra 25+ hp with Skunk2’s Pro 3+ Camshafts, our professional line of high-lift, racing camshafts for Honda’s B16/ B17/ B18 VTEC engines. Pro 3+ Camshafts are designed to optimize mid-range and top-end horsepower and torque, raising peak power 700 rpm higher than what Pro 2+ Camshafts allow for. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible.
🔧 What Skunk2 Pro 3 Plus B Series Camshaft Delivers
Compared to Stage 2:
-
Significantly higher lift
-
Extended duration
-
Maximum top-end airflow
-
Aggressive VTEC crossover
Designed for engines that live at 8,500–9,000+ RPM.
No other line of racing camshafts even comes close to Skunk2’s Pro Series. 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.
🏁 Required Supporting Mods (Mandatory)
You do not “drop these in” and hope.
✔ Dual valve springs (race-spec)
✔ Titanium retainers
✔ Upgraded valve locks
✔ Adjustable cam gears
✔ High compression pistons
✔ Ported head
✔ Standalone or advanced ECU tuning
No proper setup = poor drivability or worse.
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.
⚙ Ideal Build Scenarios
✔ 220–250+ HP naturally aspirated B-series
✔ High compression (11.5:1+) builds
✔ Road race / drag race setups
✔ Fully built bottom end applications
If you’re trying to keep factory manners, this is not the cam.
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.
