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

Performance Camshaft Manufacturers
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

DPR
DPR 2009 Subaru High Performance Camshafts
In September 2008 DPR introduced to the market the first high
performance camshafts with AVCS intake & exhaust! After 1 year out on
the market, they still prove to be the best out there for your Subaru!
DPR FI Touring Camshafts
DPR FI Touring Camshafts are a result of years of racing touring cars,
drag cars, rally, and formula cars. The profiles are proprietary and are
specific to the nature of the required application of a given sport
compact engine design. They are designed to provide optimal peak power,
fuel efficiency for the given application, and the most usable torque
throughout the entire RPM band. Cores are cryogenically treated, then
machined to finished specs, then treated again to strengthen the surface
metal, and properly orient the metal grain to fight metal fatigue and
wear. B-Series VTEC Fitment Only! Requires Valve Train Kit and High
compression pistons for maximum performance.
Estas

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.
Huskins
Engineering, Inc..
Started by Robert Bennett in 2005. The company has survived primarily on
income from contracting engineering service at automotive engine plants
and has done four retrofit controls on Landis grinding machines. We are
just getting started with grinding camshafts and we have an impressive
line up of Landis 3L CNC camshaft grinding machines and other important
camshaft manufacturing equipment. The owner has 20 years experience in
the machine tool industry and 15 years experience with grinding cam and
crank shafts.
Camshaft Grinding Service. We are an inexpensive,
high quality manufacturer of camshafts. We grind camshafts with Landis
3L CNC CAM grinders. We use CBN grinding wheels and straight oil coolant
for workpiece surface quality. We check camshafts using an ADCole 911.
Our machines have a maximum capacity of 10.5 inch diameter by 60 inches
in length with CNC grinding wheel swivel to produce controlled lobe
taper for flat tappet camshafts.
Additional Information. Press Releases Product Info etc: We accept
\\\'one off\\\' (single camshaft) custom camshaft jobs and will produce
the shaft for less than the typical retail price.
We offer product and manufacturing process development.
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.
Kelford Cams
Kelford make a massive range of performance camshafts for race and road
use. Their site includes comprehensive specs on all the cams they make
and includes information on cam timing for each cam and what other parts

Tomei
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.
