As fun as the car turned out, the current single turbo setup simply wasn't capable of delivering the power he needed. Injected Performance customized a new Speed Force Racing turbo kit. Designed around a pair of Precision P67mm turbos, the system starts at the Speed Force Racing intake and pushes air into the engine via a polished Cosworth manifold. TiAL provided a pair of blow-off valves, as well as a pair of 38mm wastegates. The exhaust travels through Burns Stainless collectors into a custom-piped 76mm GReddy Evo TT system.

A pair of Walbro 255lph fuel pumps sends the gas to 1,200cc/min injectors from RC Engineering, and a fuel pressure regulator from Aeromotive works with the Injected Performance fuel rails to keep the gas flowing as needed. An ECU from Haltech manages overall operation of the motor and keeps the fuel, ignition, timing, and boost systems running smoothly.

In order to cope with this kind of power, the stock clutch was dropped in favor of a triple-plate clutch setup complete with a lighter flywheel from Carbonetics. The Driveshaft Shop provided their Level 5 axles and CV joints. Carbonetics also supplied their beefed-up carbon limited-slip differential to make sure the drivetrain was up to the task. While the AP brakes proved quite capable of coping with the power, it was time to upgrade the suspension. A set of Tein Flex coilovers was installed and to further stiffen the chassis, sway bars from Stillen were also added.

The latest Dynojet runs have seen consistent figures of 718 hp on pump gas and a whopping 850 hp on race gas. At the moment, this is limited only by the clutch beginning to slip. However, Michael and the guys at Injected Performance haven't given up, and it won't be long before the car is pushing out four-digit horsepower-pretty extreme for a daily driver, but they say it's just around the corner.
