3K, 4K and 5K High Performance Thermostat



Born from racing technology!
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 F780 WPC High Performance Bearings





Ultra race spec High Performance F780 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 parts.
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 treatment.

4K	Main	$157.80 USD	$178.40 USD
4K	Con-Rod	$103.80 USD	$115.75 USD
