Product Details

The COMP Cams 12-251-4 Xtreme Turbo camshaft is a hydraulic flat tappet performance camshaft designed specifically for turbocharged Chevrolet small block engines. This camshaft features a 206/206 degree duration profile that provides an excellent balance of low-end torque and mid-range power, making it ideal for street-driven turbocharged applications.

Key Specifications:

  • Advertised Duration: 206°/206° intake and exhaust
  • Hydraulic flat tappet design for quiet, reliable operation
  • Optimized lobe profiles for turbocharged applications
  • Reduces pumping losses common in forced induction setups
  • Maintains good vacuum for power brakes and accessories
  • Compatible with stock valve springs and hydraulic lifters

The Xtreme Turbo series camshafts are specifically engineered to work with the unique demands of turbocharged engines, featuring shorter duration and reduced overlap compared to naturally aspirated performance cams. This design minimizes boost loss through the exhaust valve and allows the turbo to build pressure more efficiently. The result is improved throttle response, reduced turbo lag, and more usable power throughout the RPM range. This camshaft is an excellent choice for street turbo builds where drivability and daily usability are priorities.
