Tuner & Competition Camshafts
For more visit www.bloxracing.com
BLOX Racing offers enthusiasts a high performance line of Tuner and Competition Series camshafts in several different profiles. All camshafts are designed and manufactured using the latest software and casting technologies, then CNC-ground to precise tolerances and performance specifications. Each camshaft profile designed offers increased horsepower and torque across the entire RPM range. Tuner Series camshafts are designed using standard, OEM lobe designs while Competition Series camshafts are designed and cast with wider primary and secondary lobes. Although both types offer increased power and torque, Competition Series camshafts place less stress on the valvetrain and provide greater stability at extreme RPM’s. Consequently, all camshafts are cast using the same materials and standards as OEM sources. Available for Honda VTEC engines (K-Series, B-Series, D-Series, and H-Series), Mitsubishi Evolution VIII, IX 4G63 engines.
SR20DET Step 1 Cams
The redesigned HKS Step 1 camshafts provide improved performance in the mid to upper RPM range enabling a wider power band that continues up to the factory rev limit. The new camshaft profile has an 11.5mm lift that is similar to the Step 2 camshafts, but can still be used with the stock valve springs without any valve timing adjustment and modifications to the cylinder head.
Ross Racing Pistons
Mitsubishi 4B11 Piston
Evo X owners are dialing up the boost, adding nitrous and approaching 1,000hp power levels. The internal stresses and heat in these tiny 4B11 engines is ludicrous. Without a doubt, the pistons are the most critical component for containing these incredible cylinder pressures. To meet this challenge Ross designed the strongest forged piston available with a 9.0:1 compression ratio. They are forged out of 2618 T-61 aluminum and feature extra reinforcement in the pin area and pin boss-to-skirt interface. This allows the piston to retain its shape under massive boost pressures and extreme rpm.
Honda K-Series Cams
Kelford Cams announces their new line of Honda K Series camshafts, engineered to compliment horsepower levels from 225 to 450 in naturally aspirated applications. Since the early 1990s Kelford Cams has recognized the growing worldwide demand for high-performance valvetrain products to suit Japanese and European multi-valve engines. Kelford’s specialist knowledge, modern CNC grinding equipment and innovative design systems have helped them become a world leader in the camshaft market. Make power with Kelford Cams.
