Performance Camshaft Manufacturers - Performance Camshaft Design

The camshaft uses lobes (called cams) that push against the valves to open them as the camshaft rotates; springs on the valves return them to their closed position. This is a critical job, and can have a great impact on an engine's performance at different speeds. - more from How Stuff Works

Apexi
All A'PEXi performance camshafts are precision engineered on CAD systems delivering unparalleled performance. All cams are designed for competition high horsepower output. Few companies possess the technology to develop high quality cams. The GT camshafts have been primarily developed for optimal matching with our AX turbo series or comparable sized turbo. The VMAX SPL series are an aggressive camshaft lineup made for the RB26DETT Skyline GTR engine. These camshafts have already proven themselves on our 8 second 1100HP V-MAX test car.

Baty International, West Sussex, UK
New camshaft measurement and analysis software from Baty International Developed through its association with Hawk Kawasaki British Superbike Team, Baty's new CAM-Check kit enables engine tuners to collect profile data from cams that have performed well on the dyno, allowing them to check that replacement cams 11ave beerl made to exactly the same spec. Also this base data can be used to develop new profiles, specifying to the cam grinder exactly what profile changes are required and using CAM-Check to ensure that the development cam has been ground to those requirements.

Cat Cams NV Wommelgem, Belgium
Cat Cams has a complete in-house design and manufacturing cell for performance camshafts and related engine parts. Major attention is paid to advanced cam design, since the performance is in the profile To make sure all tools are present to tackle new profile design constraints, cam designer Ken Stressens also writes the dedicated calculation software (reI. Racecar Engineering, Oct 2007). Furthermore, Cat Cams extends the in-house product range by offering engine parts from well established manufacturers like PAC (valve springs), Northbridge Motorsports (conrod bolts) and JE Pistons

Crower
Crower Cams and Equipment Company, Inc., is a leading producer of aftermarket camshafts and valve train components. But over the years Crower has developed a more diverse line of products.

HKS
HKS high performance camshafts are CAD designed to optimize torque and horsepower over the widest possible power band. Each camshaft application is offered in multiple profiles, each with their own lift & duration characteristics to suit various levels of tuning.

Jun Auto Mechanic
The cam profile which influences the performance of a camshaft is the most important element in a camshaft design. At JUN, the software only for cam profile designs is used, and the automatic design by the computer is performed.

Kent Cams
Put simply we are manufacturers of all types camshafts, specialising in motorsport, short production runs, pre production prototypes and one off’s, however our in house manufacturing expertise extends to valve retainers, adjustable cam pulley’s, valve guides, chain gears, poly-v belt pulley’s, cam followers and shims.

Newman Cam, Farnborough, Kent, UK
Newman Cams is the country's premier modern and classic motorsport camshaft manufacturer. It specialises in car and motorcycle camshafts, from one off specials to small batch runs. Newman camshafts have been used in Fl, Le Mans, DTM, WTCC. BTCC. MOTO GP etl. It has all the latest technology from CNC lathes to CNC cam grinders

Piper Cams
With over 30 years involvement in motor sport we are proud to have contributed to many successes in all areas of the sport, including the MG Works Touring Cars shown here. In many cases our agreements with our clients prevents us from listing them by name, but suffice to say winners in just about every level of motorsport - from club level right up to Formula 1 - owe their success to a Piper Cam.

Piper Cams steel and chill cast camshafts, lightweight aluminium vernier pulleys, performance valve springs, spring caps shims and followers Whatever your requirements, prototypes, race, small batch production or design

Skunk2
Skunk2 Racing camshaft profiles are designed using the latest computerized valve train and modeling techniques to maximize horsepower and torque. Our camshafts are designed utilizing years of racing experience. These camshaft blanks are cast from the same foundries used by auto manufacturers such as Toyota, Nissan, Honda, and Mitsubishi, and utilize the latest in Japanese chill-casting technology.

When opening intake valve, high acceleration G※1 is required for camshaft to send as much as mixture to the cylinder in shortest time. On the other hand, when it closing valve, valve seat and valve spring will be damaged if acceleration G is too high. Asymmetrical profile must be given to the camshaftﾕs intake and exhaust valve to fill the two contrary demands; secure wide duration and high lift but prevent valve system from shock and damage, at one time.
