BMW S62 Billet Camshafts The main requirement for an internal combustion engine to produce horsepower efficiently   is the combination of a very precise mixture of oxygen and fuel, followed by ignition.   Horsepower and torque is directly proportional to the rate at which the mixture enters the   combustion chamber. This essentially means the more mixture that can be introduced into   the cylinder's combustion chamber the higher the potential horsepower output. To achieve   this airflow must be improved. On a camshaft, the cam lobe profile determines the characteristics of the power band of   the camshaft. There are several key data points that must be focused on in order to properly   design a camshaft that will perform optimally, those are: duration, lift, velocity, acceleration,   and jerk. By properly developing a camshaft profile it is possible to generate horsepower   and torque throughout the entire power band, opposed to commonly available camshaft   profiles that are proven to only increase horsepower in certain sections of the power band. Bavarian Solutions billet camshaft profiles are available for all applications, from forced   induction in the variety of supercharged setups and turbocharged setups, to naturally   aspirated applications. We also offer the service of having a custom profile developed for   your exact application to achieve maximum efficiency. Price: $4295.00
