JUN Flywheel - 00-02 Lexus IS200 GXE10 "Early" - 1G-FE-Engine
Weight: 6,3 kg
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.
Advantage by making a flywheel light
"The engine response improves if a flywheel is made light" that is often said. In case of revolving thing like a flywheel, the power (inertia power) which is always going to continue fixed rotation occurs. An engine tries to increase the number of rotation when you pedal an accelerator, but a flywheel tends to keep an idling state according to its inertia power. 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).
Weight, Strength, Balance
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.
The flywheel of JUN is performed design and fabrication of at dimensions same as genuine parts.
