HKS R TYPE Intercooler Kit for GRB Subaru Impreza WRX STi
Get the Turbine’s Real Power and Increase Engine Torque!
The cooling efficiency of an intercooler is affected by many factors including the frontal surface area of the core, cooling fin design and air flow through and over the core. HKS has increased the size of the core over stock to increase the air flow over the core.
New type cooling fin now offers improved heat radiation. Core end tanks have been designed to flow the compressed air evenly across the whole intercooler core. All these factors will maximize reduction of intake air temperature which increases air density. Increasing the range of fueling and ignition setting making it possible to deliver more power and torque.
Along with cooling efficiency, pressure loss reduction is one of the most important aspects of intercooler performance. If the pressure drop is significantly high, throttle response and the torque is reduced.
However, reducing the pressure loss and improving the cooling efficiency are contradictory, and the lower the pressure loss, the worse the cooling efficiency becomes. A large cause of pressure drop is the cross sectional area of the tubes in which the air flows and inner fin layout and shape. HKS has emphasized cooling efficiency yet achieved a low resistance design with thin fins.
Tube design has been also considered in many possibilities and increasing the cross sectional area. With these measures in place, high levels of cooling efficiency have been achieved without sacrificing pressure drop.
R TYPE is designed for circuit use. Ideal to use with a stock replacement type turbine to wastegate type large size turbine. This intercooler derives better turbine performance regardless the engine rpm during driving on a straight track and acceleration after cornering.
The weight is approximately 25% lighter than a conventional product (in-house comparison).
