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.
Why is WPC Superior?
The WPC process is unrivalled 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 conventional methods of surface treatment.
WPC has the capacity to treat carburized, nitrided and plated parts without noticeable dimensional changes, and, upon completion of treatment, no further modifications are required of the parts. The strength and durability improvement on the surface after the WPC treatment is unsurpassed by any current methods.
Treatable products include steel, aluminum, titanium, copper and brass and soft surfaced bearings. WPC can treat any metallic item in a disassembled state.
Reduced Friction
The fine grooves, that are intrinsically engraved into the product surface at the time of machining, are transformed into micro-dimple indentations by the impact of the ultra-fine media during WPC treatment. These dimples then act as oil reservoirs.
Thus, oil that would normally drain away, through the grooves in an untreated product, when pressure is applied, is instead retained in the dimples of a WPC treated product. This helps to keep the surface lubricated.
Furthermore, solid lubricants such as Tin (Sn) and Molybdenum Disulfide (MoS2) can be utilized as media in the WPC process to embed them into the product surface. This reduces friction and improves the life and efficiency of the product to an even greater level. This process is called PIP(Powder Impact Plating).
Greater Durability
The ultra-fine media of the WPC process, when projected at high velocity towards the product surface, creates compressive stress at the impact points. At the same time, a micro thermal reaction takes place. It effectively seals minor surface fractures. It also allows a condensed surface to form that has improved density due to compaction. This altered and highly compact surface condition overcomes the problem of brittleness, that is usually encountered when metals are hardened.
The numerous impacts during the WPC process not only increase the residual compressive stress but also cause it to reside a lot closer to the surface. The cumulative result is a product that has a durability unrivalled by conventional peening methods.

*Optimized 'velocity' and 'acceleration'.
*Designed for high power setups.
*Optimizes engine performance.
*Higher lift than other profiles of the duration.
*Reduced stress/wear on the valve train.
1. The VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the 'lift curve' (see fig. below) which in turn generates more power. (Greater area under the 'lift curve' = greater air intake).
・CAM ACCELERATION:LOW
・LIFT:LOW
・AIR INTAKE:LOW
・CAM ACCELERATION:HIGH
・LIFT:HIGH
・AIR INTAKE:HIGH
2. Unlike the valve opening, the VALC profile ensures that the valves close at a slower rate, helping to prevent common valve train related issues.
3. With a conventional direct-acting valve train, the maximum lift is usually determined by the size/diameter of the valve lifter. Selecting a high-lift camshaft without taking this into consideration often results in the camshaft lobes travelling beyond the surface of the valve lifter. This causes the lobe to make contact with the edge of the lifter, damaging both components over time. (see fig. below). Therefore, the ideal performance orientated high-lift camshaft needs to have a profile that maximizes lobe travel on the lifter without exceeding the outer edge. VALC profile camshafts have achieved this ideal by deliberately reducing the maximum cam velocity to limit lobe travel on the lifter surface.(Maximum cam velocity = lobe travel distance on lifter)
High lift profile without taking lifter size/radius into account.
4. Compared to standard profile camshafts of the same lift, VALC profile camshafts are able to then then off-set the difference for even greater lift/performance gains.

]]>The cooling system of a car may seem to work fine without any additional equipment attached to it but that will not save the cooling system of your car from any environmental damage like rust due to the way coolant and the radiator works.
Rust can be formed inside the cooling system of your car due to air getting into the radiator after the engine has cooled down.
When the coolant cools after the engine has been turned off, it contracts in volume which will result in a drop of temperature and pressure inside the radiator allowing the air to enter the radiator through the radiator cap.
That air will result in the formation of rust in the cooling system when it comes into contact with the metal in the system.
When rust has formed inside the radiator, you will have no choice but to flush out the system and replace the antifreeze. However, a radiator coolant overflow tank can prevent this problem before it even starts. This saves you the expense of frequent coolant replacements and possibly the expensive cost replacing a radiator or other components of the cooling system.
How a Radiator Overflow Tank Works
The radiator overflow tank is fairly simple device but it can save you a lot of money by preventing rust from forming in the cooling system of your car. When the engine is running at its optimum performance, it needs the engine coolant to keep it within the operational temperatures.
The engine coolant absorbs the heat from the engine. When this coolant heats in the radiator, it begins to expand causing an increase in the pressure in the cooling system of that vehicle.
When the pressure of the coolant in the radiator surpasses the designed pressure of the radiator cap, the antifreeze passes the radiator cap seal and flows into the coolant reservoir overflow tank through the overflow tube.
When the engine has been turned off, the coolant will start to cool down as well. As it cools down, it will contract in volume as well. This decrease in volume will result in a vacuum because of a drop in pressure.
Due to this vacuum, a vacuum valve in the radiator cap opens allowing the coolant which was flown into the radiator coolant overflow tank back into the radiator.
In older vehicles with no coolant overflow bottle, the air is sucked into the radiator instead of coolant which results in the formation of rust. So installing an overflow tank in your car is a good way to not only maintain the cooling system of your car but to save repairs and replacement expenses in the long run as well.

JUN Machine Shop has added the GT Surge Tank for Toyota FT86 and SUBARU BRZ. Now it is on sale.
We considered the characteristics of the natural aspiration engine for making this surge tank. Then we paid attention to inertial supercharge properties of the intake manifold to make use of a quality of the natural aspiration. The inertial supercharge peaked in the stock in about 7200rpm, but we calculated a port cross section and the port length and designed it in about 8000rpm to become greatest. In addition, we attach funnels to each branch in the surge tank and note the distribution of each cylinder.
