My AMG is bone stock. No BMW intake or throttle and no sc. It has good power up to 6800 but it does feel it starts maxing the cam by 6600. So 7 is abt the max the engine in its state can rev. Any way if u calculate piston speed u will find 7200 is over any acceptable limit to have the engine running at for any period of time.
