ow cost Aftermarket cam regrind esp. for BSP and other stock classes. Designed to meet most stock rules. CL1 (Old Style)HI TORQUE for 5500 RPM

Designed in 2013, the intake and exhaust lobes allow the CL-2R to run at higher RPMs before the engine goes into uncontrolled valve float. By retarding the cam 2 degrees the power band is shifted around 200rpm, giving the cam more top end.

The CL3 utilizes the -5 duration check, in the AKRA rule package, by allowing a softer ramp rate on the nose of the cam. This design has shown gains in the 6200+ RPM range with minimal loss in peak horsepower.

The CL4 is specifically designed for the NKA rule package. With no minimum duration requirements, we were able to smooth the nose of the cam allowing it to rev well into the 7000 RPM range. The CL4 shows gains in the 6600 RPM range over our current CL3. This cam comes buffed, further smoothing the nose, to take max advantage of the 10.8 springs.
