Keeping It Cool
Thermal viscosity breakdown within oil is the number one cause of engine failure. To remedy the problem, Team Cyber uses an HPI oversized oil cooler and TOMEI oil thermal killer unit. Combining an ARC removable radiator overfill tank, A'PEXi three layer aluminum radiator, Power Enterprise three-layer hose and RALLIART thermostat, coolant temperatures remain consistent as the car it continuously taken to the ragged edge.
Fuel For Thought
Fuel management has become a critical factor in extracting horsepower from the Mitsubishi EVO. EVO owners have learned this particular power plant is not aftermarket-parts friendly without the proper tuning. Sun Automotive/HRS Garage devised an intricate primary and secondary fuel system, taking to heart the idea that you can never have too much of a good thing. Using a Power Industries 255-lph fuel pump as a primary source, fuel is delivered into a custom Zenitani surge collector tank and exited with the aid of a 282-lph BOSCH inline pump, eventually making its way into the Power Industries 1000cc injectors. Regulating the fuel delivery is an A'PEXi fuel pressure regulator. Within the heart of the fuel management for the EVO resides a custom HKS Fcon V-PRO, controlling all aspects of ignition timing, spark and fuel delivery.
Taking Control
When dealing with AWD vehicles, such as the Mitsubishi Lancer Evolution, you have to remember they tend to have strong understeer, even more so when horsepower becomes prevalent. With 700 hp on tap, it becomes difficult to flow all four tires evenly, gripping and grabbing smoothly through the turns. Takizawa, standing beside the crew, closely analyzed the CyberEvo on practice day, tearing through the Motegi twin-loop course. Team Cyber determined the differential and suspension were in need of adjustment. With the Rear LSD too strong, the crew decided to initially drop the pressure to 4k, lowering the strength of the diff. Combining a Cusco MZ TYPE-RS limited slip up front and Cusco MZ-RS in the rear, adding or removing the clutch plates within the housing has given the team the ability to custom tailor the vehicle to any track. Upgrading the factory suspension, Team Cyber enlisted the help of TEIN Japan. TEIN has been at the forefront in suspension technology for years with many of the top tuners in Japan using their suspension. A set of custom TEIN coilovers and AP Engineering pillar mounts reside on all four corners of the vehicle. Most noticeable in the alterations of the EVO's suspension over stock is the hunkered, widened stance. A quick glance at the vehicle and its obvious the width of the fenders and tire placement reveal the lower control arms have been extended. Rounding off the suspension is a set of Cusco front stabilizer brackets. Applying traction to the tarmac is a set of Volk Racing CE28 17x9.5 (+15 offset/front) and 17x9.5 (+35/rear) wrapped in 255/40R17 Advan A048(S). Bringing the Volk's to a screeching halt is a set of HRS Garage original GT rotors and a set of Powercraft OX brake pads. Minutes after the December 9, 2003, record setting time at Tsukuba Circuit, Tarzan stated, "The car was running great this time but I was experiencing some initial countersteer. If we can get the counter to a "0" balance I am sure we can improve on a .2 to .3 second overall lap time compared to our previous run."
