Audi Sport Quattro – KEMRacing in the Isle of Man

Posted on 24 August, 2012

The inline 2.1 liter five-cylinder turbocharged engine has 480PS (350 kW). A recirculating air system helping the turbocharger spinning at high RPM, when the driver does not apply the throttle allowed the engine to resume full power immediately after the resumption of full throttle. This was extremely good move, because it reduced the turbo lag a lot and boosted the engine to 507PS (373 kW) at 8000RPM.
