  • JUN Type 1 Camshaft IN 75(300)-10.9 Acura Integra B16A/B/B18C

    JUN Type 1 Camshaft IN 75(300)-10.9 Acura Integra B16A/B/B18C

    JUN Type 1 Camshaft IN 75(300)-10.9 Acura Integra B16A/B/B18CThe 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. In order to test the cam shaft designed on the desk, the engine bench system of JUN which has combustion pressure measurement equipment is used. This system can analyze the state in a combustion room for every crankshaft angles. Various profiles can be tested. Even if it says a camshaft in a word, the profile form is various by the type of a car. Profile form is decided in consideration of the difference of valve motion method etc. (direct type, a locker arm type, strength of moving part, valve size, port and combustion room form). If depending on types of a car, a profile may be restricted by the wall in a head, lifter hole size, locker arm form, etc. At JUN, when developing a high camshaft, the detailed data for each type of a car is taken, development is furthered simultaneously with a valve spring and retainer, and the optimal profile is determined. In order to manufacture a highly precise camshaft, it can be said that the cam grinder with a high performance is indispensable. In our company, the CNC master less grinder with high processing accuracy was introduced from the early stage, and the camshaft has been manufactured. Since the camshaft grinder of our company can input the program data of a cam profile very finely, it can grind in the cam profile based on a design. The quality control is performed on the high standard like other products. The user is provided with the high product of quality. You have to raise "filling efficiency", in order to obtain a high output. Being required of a cam is lengthening time which the valve's is opening. It is necessary to increase the amount of cam lifts in order to lengthen time which the valve is opening. The negative acceleration will become large if the amount of lifts is increased simply. The "jumping phenomenon" in which a valve separates from a cam, and the "bounce phenomenon" which is bounded when a valve contacts a valve sheet ring occur because when negative acceleration becomes large, the acceleration of a valve will exceed the acceleration of a cam. These phenomena not only spoil the performance of engine original but cause breakage of engine. The high camshaft must realize the conflicting element with which "extension of time which is opening the valve", and "reduction of negative acceleration". JUN high camshaft took positive acceleration large , and the action time of negative acceleration is keep a long time by shortening positive action time. By doing so, when a valve moves from opening operation to closing operation, a valve can move as smooth operation and can prevent jumping. Since positive acceleration becomes large at the side of close, the valve just before cl

    JUN Type 1 Ti Valve Retainers Acura Integra B16/B18

    JUN Type 1 Ti Valve Retainers Acura Integra B16/B18In order to obtain a high output, it is necessary to turn engine by high rotation. However, when using engine in a high rotation region, valve jumping becomes easy to happen and the danger of engine breakage increases. Therefore, it is required for tuned engine to make a movement part light. The role of a retainer is a stopper for valve springs, retainer needs to be extremely strong and lightweight for reliability and engine response. The JUN Titanium Valve Retainer has been developed with emphasis on both strength and weight in mind. Furthermore, the Type2 valve retainer is performing the special surface treatment. And compared with Type1 (conventional article), wear resistance of it improved very much. Specs:Diameter: stockWeight: 7g This product ships EMS directly from JUN Machine Shop in Japan. Minimum shipping cost is $40. Upon ordering you will be contacted with a shipping quote before your order is finalized. Please allow 4-8 weeks for delivery.

  • JUN Ultra Light Flywheel Nissan Skyline GTR RB20DE(T) (225mm)

    JUN Ultra Light Flywheel Nissan Skyline GTR RB20DE(T) (225mm)

    JUN Ultra Light Flywheel Nissan Skyline GTR RB20DE(T) (225mm)JUN could achieve manufacturing its original flywheels about 200% more strength compared with normal flywheels. It was forged using Chrome-molybdenum steel. The power of inertia rotation can be decreased by reducing the excess weight, and therefore, its strength directly passed through to the high response. JUN Ultra Light Weight Flywheel is targeted the customers who regard the higher rotation area for their highly modified engines. This flywheel is also designed to be strong as well as light-weight, and forged using Chrome-molybdenum steel.If a flywheel is made light, it is said that an engine response improves. In case of revolving thing like a flywheel, the power (inertia power) which is always going to continue fixed rotation occurs. When an accelerator is stepped on in from an idling state, a flywheel tends to keep an idling state according to its inertia power, although engine is going to raise rotations. When inertia power becomes large, much time is needed for going up rotation. In the case of the JUN lightweight flywheel, since weight (especially flywheel perimeter part) is light, there is little inertia power of influencing rotation of engine. Since time to go up rotation is shortened, the response of engine to a accelerator becomes quick (a response improves).The JUN light weight flywheel is made from the optimal weight and optimal form which were set up for each type of a car from the chrome forge material. By shaving all circumference of the chrome forge material, the variation in weight and the deviation of balance are pressed down to the minimum. Processing for raising wear durability and heat treatment etc... is performed in the surface. Various know-how for realizing lightness, strength, and high balance is condensed to the JUN light weight flywheel.Weight: 5.1kgPicture is for representation only. Actual product may vary.

    JUN Ultra Light Flywheel Nissan Skyline GTR RB20DET/RB26DETT

    JUN Ultra Light Flywheel Nissan Skyline GTR RB20DET/RB26DETT JUN could achieve manufacturing its original flywheels about 200% more strength compared with normal flywheels. It was forged using Chrome-molybdenum steel. The power of inertia rotation can be decreased by reducing the excess weight, and therefore, its strength directly passed through to the high response. JUN Ultra Light Weight Flywheel is targeted the customers who regard the higher rotation area for their highly modified engines. This flywheel is also designed to be strong as well as light-weight, and forged using Chrome-molybdenum steel.If a flywheel is made light, it is said that an engine response improves. In case of revolving thing like a flywheel, the power (inertia power) which is always going to continue fixed rotation occurs. When an accelerator is stepped on in from an idling state, a flywheel tends to keep an idling state according to its inertia power, although engine is going to raise rotations. When inertia power becomes large, much time is needed for going up rotation. In the case of the JUN lightweight flywheel, since weight (especially flywheel perimeter part) is light, there is little inertia power of influencing rotation of engine. Since time to go up rotation is shortened, the response of engine to a accelerator becomes quick (a response improves).The JUN light weight flywheel is made from the optimal weight and optimal form which were set up for each type of a car from the chrome forge material. By shaving all circumference of the chrome forge material, the variation in weight and the deviation of balance are pressed down to the minimum. Processing for raising wear durability and heat treatment etc... is performed in the surface. Various know-how for realizing lightness, strength, and high balance is condensed to the JUN light weight flywheel.Weight: 5.7kgPicture is for representation only. Actual product may vary.
