Yella Terra - Whipple Upgrade Kit for L67 ECOTEC Click on images to enlarge

Key Features: Water to air intercooler Twin screw rotors Adiabatic efficiency up to 80% Less parasitic loss when on boost Modular pulley system Black finish on casing The Whipple supercharger is the key to making extreme power from the L67, where the M90 is reaching its limits with pulley sizes and pumping out lots of heat, the Whipple is just getting started, its twin screw rotors have a efficiency rating of up to 80%. To further help the supercharger the adapter plate used to fit the Whipple to a L67 also incorporates a water to air intercooler to cool the compressed air as much as possible before it reaches the intake valve. On top of this the blower has less parasitic loss when it is on boost which means more peak power. There is a small compromise though with any twin screw superchargers, due to the rotors constantly compressing air even when the engine is under light load, the parasitic loss when the engine is not on boost is slightly higher.

Key Features: 25-50% increase in torque Retains drivability Retains emissions Modular pulley system The Terra charger is the ultimate modification for the naturally aspirated ECOTEC. Once bolted on it will increase torque/power by 25-50% depending on supporting modifications. Drivability and emissions will still be excellent and you will have support to fit smaller pulleys at a later stage if required to increase boost even further.

Yella Terra - "Terra Charger" EFI V8 5LT Conversion kit

Key Features: 60%+ incease in power 60% increase in torque No internal engine modifications Modular pulley system Instant throttle response Incredible low/midrange torque Incredible low/midrange power The 8psi boost kit will yield over 60% increase in power from standard while torque has increased by 60% over standard at a usable powerband of 2800rpm. All this can be achieved with standard engine internals and ECU (upraded ECU is optional with custom tuning). On the road, results are even more impressive with instant throttle response, awesome low end- mid range torque and power that just keeps building. All these gains are delivered with remarkable fuel efficiency compared to standard. The kit has a very professional finish and maintains as much OEM hardware as possible. It is also a true bolt on installation and comes with every component to complete the job including 2 supplementary injectors on the standard kit, an independent electronic control unit with analogue adjustment and all hoses, brackets, pulleys, belts and fasteners. Additional electronic unit is not required with the custom tune kit, however a set of supercharged injectors is required. Please purchase through ChipControl Store
