Skunk2 Racing camshaft profiles are designed using the latest computerized valvetrain and modeling techniques to maximize horsepower and torque. Their camshafts are designed utilizing years of racing experience. These camshaft blanks are cast from the same foundries used by auto manufacturers such as Toyota, Nissan, Honda, and Mitsubishi, and utilize the latest in Japanese chill-casting technology. Skunk2 Racing camshafts are ground to exact specification using CNC cam grinding machines and are subjected to hours of performance and durability testing. Skunk2 Racing camshafts must pass stringent quality control standards that exceed OE requirements.
Stage I: Stage I profiles are designed to offer the widest possible powerband and be compatible with factory valvetrain components. These camshafts are designed to retain stock idle and are currently CARB EO-pending. Upgrading to Skunk2 Racing valve springs is recommended. Stage I profiles are relatively easy to tune for maximum power output.
Stage II: Stage II profiles are more aggressive than Stage I profiles, and are designed for modified engines operating at higher rev ranges. Upgrading to Skunk2 Racing valvetrain components is required for proper operation. Stock idle and emission characteristics may be slightly compromised, but fair-to-good driveability allows them to still be used on dual-purpose vehicles. Proper tuning, an upgraded intake system, and an exhaust system are required in order to maximize the potential of these camshafts. Do not use oversized valves.
Stage III: Stage III profiles are designed for purpose-built race engines with high-rpm capabilities only! Upgrading to Skunk2 Racing valvetrain components and extensive engine work is required for the proper functioning of these camshafts. Compression and engine flow must also be significantly increased. Stage III camshafts should be installed and tuned by professional engine builders only! Do not use oversized valves.
Turbo: Turbo profiles are designed for engines with forced induction. Aggressive lift and valve opening/closing motions allow these cams to maximize power with a minimum amount of overlap. Each profile is designed with extensive input from the top racers in the sport compact industry.
Notes
Pro Series: Pro Series valve springs recommended for Pro-Series applications!
99 GSR. These cams were drop in installation. My previous dyno was 148 hp with bolt ons. My current dyno with cams, springs, retainers,is now 180 hp.On street tires my 1/4 mile time & speed has gone from 14.59 @ 94.2 mph to 14.12 @ 99.8 mph. These cams pull really good once they are in VTEC. I need larger injectors to run over 8000 rpm, but they tell me I should run up to 9000 rpm with new injectors. Overall these cams were a little less than what I expected (I was really hoping for a 13 second car).
