Pro Series Pro 1+ Camshafts

The Skunk2 Pro Series Pro 1+ camshafts are designed to significantly enhance the performance of Honda B-series engines. They feature Skunk2's Fast Ramp and AMAX technologies for improved engine response and power delivery. These performance camshafts are engineered to operate effectively within a broad RPM range, from 1,500 to 9,000 RPM. Installation of the Pro Series Pro 1+ camshafts requires the use of Pro Series Valve Springs, Titanium Retainers, and Skunk2's Lost Motion Assembly. For optimal performance, it is recommended to also install a fuel pressure regulator and/or upgraded fuel injectors, a VTEC controller, and a modified ECU. The technical specifications include an intake centerline of 98° ATDC and an exhaust centerline of 105° BTDC, with a valve clearance of .007” for intake and .008” for exhaust. These camshafts are designed to provide estimated gains of 15-20 horsepower and 18-22 lb-ft of torque. They are compatible with a wide range of Honda Civic and Integra models from the 1980s through early 2000s, specifically those equipped with B-series VTEC engines.
