'M6' doing 211MPH in Greece!
 

Whoa! That baby is in the peg range...

Yeah pretty insane stuff!! Obviously had the limiter removed lol!

Even without a limiter there's no way a stock M6 is going to see a true 211mph. A modern 911 or Corvette needs 500hp to go 200mph, and the M6 isn't quite as slick. Sorry to burst your bubble...

try 10% speedo error and you'll have his actual speed.

Did anyone else notice that once he passed the last marked speed on the dial the traction control light went on :confused: ? What was THAT all about?

This is a Kelleners M6 with 557 bhp ( camshafts,Ecu,headers and exhaust ).
It has been tested with Gps and managed 328 Kmph.I know this car very well.
Indeed 340 is very optimistic but still 328 is very respectable IMO.

nice bit of torque steer at the start.

204mph sounds plausible for 557 crank hp
