The N55 turbo straight six is bereft of power-adding tweaks due to series regulations that include a restrictor plate on the turbo and limited boost. ADF and friends have worked over the turbo, exhaust, and ECU, however, so the power train is still good for over 400 horsepower and 440 pound-feet of torque – a tidy increase over the 300/300 ratings of the standard production cars.
In addition, the car's limit weight has been reduced down to 2,998 pounds. Much of that savings was recognized using carbon fiber machines from the M Performance catalog. The team also borrowed a set of 14.5-inch front brake discs and 18 inch wheels from the minds at M. ADF Motorsport say this is the first example of a production-based direct-injected race car.
