These special cam
profiles increases the mid range power that's missing in
most cams, while keeping up with the peak power of higher
duration camshaft designs.
As with all our products, this too is made with the highest
of precision, while also taking into account other factors
such as idle stability, valve-train noise, and fuel
consumption, to create the ultimate in camshaft technology.
Other camshaft specs (duration/lift) are available for

4K Heavy Duty High Performance Timing Chain
This reinforced timing chain has been permeated uniformly
with a light coat of manganese phosphoric acid. This process
makes the chain 4 times as resistant to wear! The chain also
keeps the motor at peak performance by itís resistant to
stretching from prolong use, which can lead to mistimed
valves. This chain has stops heat seizing between the links
by remaining flexible and reducing friction, to have a
smooth flowing movement.

71 Degrees Celsius Low Temp Stainless Thermostat
What is the optimum
temperature to get the most power from the engine?
Different parts of
the engine are at various coolant temperatures. For example,
the temp gauge is reading at 80 degrees Celsius but at the
back of the motor, it is between 85 and 90 degrees Celsius,
which means it is detonating. The perfect temperature
for optimum performance is the temperature right before
detonation, measured at the cylinder. However, in order
to achieve this temperature, it is absolutely necessary to
have good cooling efficiency and a low temperature thermostat.
The thermostat opens the valve at 71 degrees Celsius and
allows the coolant to flow earlier to prevent overheating and
bring out the maximum performance from the motor.

4K F770 WPC High Performance Bearings
Ultra race spec High Performance F770 Metal Bearings
with WPC Treatment for friction reduction.
Highly recommended for high performance and racing
engines. "WPC" Molybdenum bearings have a
low coefficient of friction, reduce the rotational
torque, which also enables the bearing to last longer
and hold up to higher pressures.
What is WPC?
WPC is a proven process that has been utilized for many
years in the racing and automotive industry.
WPC is not a coating, it is a treatment that enhances
the surface to reduce friction and strengthen engine
WPC achieves this process by firing ultra fine particles
towards the surface of a product at very high speeds.
The resulting thermal discharge permanently changes the
surface, strengthening structure and creating a harder
more durable final product.
The WPC process is unrivaled in treating engine parts
and other surfaces that have contact points of friction.
WPC is superior because it is not a coating; it is a
permanent surface treatment that reduces friction while
strengthening the part. It's unique micro-dimple
formation pattern greatly reduces friction and is
unmatched by any current conventional methods of surface
