BTR V2 Series Camshafts
BTR V2 Series camshafts are designed for excellent performance and drivability. The V2 is a revised camshaft that provides more average torque, higher peak power, and a maximum depth heat treatment. The maximum heat treatment depth is achieved by using cam cores made within a few thousandths of final grind size. Numerous grinds for turbo, supercharged, and naturally aspirated engines are available for your project—all backed by years of experience, knowledge, and a passion for power.
BTR V2 Series camshaft features include:
* Revised camshaft center lines for increased average torque
* Engine dyno verified to produce more power
* Each "stage" has a specific cam core
* Maximum heat treatment penetration
