BC 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.
Longer duration profile for added rpm. Intended for fully built engine. Rough idle quality. Tuning and ECU mods recommended. Requires kit BC0200. Fits S13 (non-VTC) and S14/15 (VTC) cylinder heads.
