Brian Crower BC0021 Stage 2 Boost Camshafts For Honda Acura B18A B18B B20B

Stage 2 Boost Camshafts Honda Acura B18A B18B B20B

Brain Crower high performance camshafts are ground on state-of-the-art CNC cam grinders to insure accuracy and tolerances to within .02mm. Every BC camshaft profile has been prototyped and dyno tested for proven horsepower results prior to placed into mass production. By grinding cores in high volume, Brian Crower, Inc. is able to pass the cost savings on to the end user. Quality at an affordable price.

BC uses small diameter grinding wheels during the finishing phase when applicable to generate a more aggressive ramp rate for a faster cylinder fill rate. More air + more fuel = more power. Although it takes longer to grind the cams, research and development has proven that the inverted radius created by the small grinding wheel on the opening side delivers more horsepower on radius and roller rocker applications than the conventional, large diameter grinding wheels.

All BC cams are checked on a high speed, sub-micron accuracy measuring gauge. The Adcole Camshaft Measuring System uses individual measuring heads for each cam journal and cam lobe, with .01 micron resolution, taking one datum point each 1/10th of a degree or 3,600 data points per revolution. Measuring camshafts for rise error and chattermark detection, this model can measure 200 parts per hour.

Camshafts designed for forced induction (turbo or supercharger), as well as mild nitrous use with smooth idle. Short duration profile builds cylinder pressure by reducing overlap, high lift for more air intake. Requires spring/retainer kit BC0020. Price is per pair.
