The FK8's water temperature cooling system cannot keep up with the amount of heat generated by the genuine product. As the main point Turbo heat generation amount is very large, such as a turbine for the high output capacity shortage and the fins issues radiator core hard spots hardly strike the traveling wind core heat does not remove easily in-engine room.

Regarding this FK8, it is necessary to improve the cooling performance not only for the thermostat, sports coolant, and aero parts, but also for the total cooling performance, and improving the heat exchange performance of the radiator is a major point for improving the cooling performance.

J'S RACING has been conducting radiator tests and prototypes for a long period of time, but have adopted a triple-turn type in search of specifications that exceed those of conventional aluminum radiators. Redesigned so that the outside position of the cooling water can be changed and heat exchange can be performed evenly over the entire area. Although the design has inevitably increased the number of parts and costs, it was an unavoidable decision to lower the average water temperature even once.

As a result of a comparative test at the Suzuka Circuit International Racing Course using J'S RACING demo car, the water temperature during the lap was -25 ℃ at maximum and the average -15 ℃ cooling effect was exhibited in the fully open running of 6 laps including INOUT, and the water temperature rise speed. We were able to confirm the decrease and the increase in the speed of decrease in water temperature. (* 1, * 2)

By stabilizing the water temperature it is possible to obtain various benefits such as power down and prevention of fuel consumption deterioration by correcting the high water temperature of the ECU.

It is a must-have item not only for street users but also for circuit users!

  • Genuine tube width - 5mm→10mm
  • Genuine fin pitch - 1.5mm→3mm
  • Thickness - 48mm
  • A cooling fan and air conditioner can be installed.
  • Flex round processing adopted

This product is subjected to "flex round processing" made by an integrally molded press. As a result, it is possible to mold without changing the plate thickness of the bent or folded part, and it is possible to increase the strength and reduce the weight. Efficiently flowing the cooling water inside improves the heat dissipation effect and prevents the water temperature from rising when running at full throttle.
