Auditography featured this amazing 1984 Audi 80 Quattro (B2) powered by a turbocharged 2.2 L 20v inline-five (AAN). The motor uses Wossner pistons, SCAT rods, 80 mm throttle body, 850 cc injectors, custom exhaust manifold, and BorgWarner EFR7163 turbocharger. The upgrades allow the motor to produce 605 hp (444 kW) and 700 Nm (516 lb-ft) of torque on a ECUmaster EMU Black ECU. Behind that is a six-speed manual transmission with a Wavetrac limited-slip differential and a Torsen central differential. The 1240 kg (2670 lb) car decelerates thanks to Brembo four-piston calipers with 325 mm rotors in front and Audi S4/C4 calipers with 269 mm rotors in back. Listen to the inline-five scream in the video below.
