Blower Drive Service Co. is a developer of products as well as a user of these same products. Working for years with camshaft technology, BDS has perfected numerous camshaft profiles specifically engineered for the performance enthusiast. Too often, a recommended "blower cam" is simply a "cam", called a blower cam. These profiles do not optimize performance. Camshafts are "application sensitive", and the needs of a given motor are best satisfied with proper camshaft selection. With over 39 years of blower experience, BDS knows which camshaft will maximize your performance needs.
Each of BDS "maximum effort blower camshaft designs" develops high torque at the front end of the RPM scale and extends this torque throughout the RPM range. The hydraulic "blower cam" profiles provide the luxury of maintenance-free operation, providing rough and controllable idle characteristics with the broad torque band and excellent power. All this performance is available without over-taxing the valve train. Fuel economy is always possible if you control your enthusiasm with the gas pedal!
BDS solid lifter profiles offer improved performance over hydraulic designs, while extending the RPM range and maximizing both torque and horsepower. Rough and controllable idle is normal, while use of automatic transmissions with higher than stock stall speeds work well with this design. There are numerous profiles for both the hydraulic and solid lifter camshafts. Extended "valve train life" with optimum performance" becomes reality with these blower cam profiles.
Roller camshaft profiles allow maximum performance! Rapidly opening valves and a higher valve lift are possible with a roller camshaft design. More life and duration, combined with faster opening and closing valves, means greater air flow. Greater air flow means more power is possible. BDS recommends you to use this type of camshaft profile in any all out performance efforts. These roller cams reduce valve train friction, but usually require very heavy valve spring pressures. This increase in spring pressure makes higher RPM and faster acceleration possible. This added valve train load shortens over all valve train life, and increases valve guide wear. Reduced spring life is common as well. These symptoms are expected and common in any high-performance or racing application. Due to the high maintenance and short life expectancy, BDS recommends that you limit the use of these roller camshaft designs to maximum racing applications only!
