WALAS MotorSport built this Audi S4 (B5) to drag race in the Polish street legal class. Under the hood sits a twin-turbo 4.2 L Audi V8 featuring forged rods and pistons, Cat Cams camshafts, and two large Pulsar PSR 3582 Gen2 turbochargers. The result is an eight-cylinder motor producing 1,491 hp (1096 kW) and 1,525 Nm (1124 lb-ft) of torque. Behind the monster motor is an upgraded 8HP eight-speed automatic transmission from an Audi RS6 (C7) with a Turbo Lamik TCU. The car’s best quarter-mile is 8.431 sec at 281.57 km/h (174.95 mph). WALAS MotorSport plans on swapping to Pulsar 7170G turbochargers which will be capable of 2300 hp (1691 kW).
