Think this is reasonably new but here is link to 7:22 lap of the Nurburgring by the Loaded M3 CSL which is pushing out over 600bhp thanks to a supercharger! This is a pretty quick lap on Michelin Pilot Cup tyres, especially when you think the Zonda F Clubsport lapped it a short time ago at 7:27 and took the production car lap record! Its also open session so there are a few other cars on there! Just cant even imagine the size of balls needed to achieve this time although a few laps on GT4 gives you some idea of how fast you need to be going!!
