HKS USA, Inc., the premier manufacturer and supplier of premium automotive performance systems, launches the first of its proprietary design HKS GTII Series turbocharger kits, the GTII 7460R.As the first of the new HKS turbocharger line, the GTII 7460R incorporates a reverse rotation turbine design that provides the benefit of a bolt-on application, stock replacement upgrade turbocharger for the Mitsubishi Evolution IV-IX.
The special cast turbine and compressor housings of the HKS GTII 7460R allows it to be a true bolt-on upgrade for the Mitsubishi Evolution IV-IX by utilizing the OEM exhaust manifold. The HKS GTII 7460R is also a twin scroll, reverse rotation turbocharger. This design allows for a shorter and straighter exhaust path to the turbine wheel, delivering the benefits of less restriction and increased boost response while allowing full spool and stable boost pressure throughout the RPM range. Intake and exhaust port designs optimize the flow area to allow an increase in air-flow capacity while the ball bearing center housing rotating assembly (CHRA) improves low-speed response and quicker boost pressure ramp up times Use of premium materials include inconel® for the turbine wheel because of inconel’s resistance to oxidation and its ability to maintain its structural integrity in high temperature atmospheres. Special heat resistant cast material increases the reliability and durability of the turbine housing.
The GTII 7460R produced 373.4 WHP and 355.62 ft. lbs Torque with the boost set at 1.78 Bar (25.8 PSI) on 93 octane.
