Drews 909 Hill Climber Camshaft 392 Lift 244 Duration 110 Lobe Center 909CAM

Description

The Drews Hill Climber 909 camshaft is our own in house cam designed by off road racers for racers, hill climbers, and drivers who want a useable powerband. We heard from many customers that they could not let out of the throttle midway up a hill and then get back into the power easily without their engine struggling to torque back up.

This cam delivers tremendous mid range torque which allows you to feather the throttle as needed up hills. Peak power and torque come in between 1500 RPM and 5500 RPM. Some clearancing is required with the larger 82mm+ cranks.

The secret sauce on our 909 grind is the built in advance and lobe separation, moving the powerband down to where you actually ride. This cam is 3 degrees advance and shows off well with additional advance. Verifying valve to piston clearance for high lift applications is critical for correct cam timing.

The ideal engine would be large cc, dual carb, ported head setup with valvetrain to support high lift and compression. This cam really shows its muscle with ratio rockers and high-lift valvetrain.
