Compare this 10.446 @ 134.43 pass for the Stage III C63 AMG to another Australian C63 AMG running the Stage II Weistec supercharger which turned a 10.8 @ 129 in the 1/4 mile. That car also was running pump gas. The larger 3.0 liter blower in the Stage III kit is simply capable of making more power with less heat than the 2.3 liter and is able to do so even on pump fuel.
Either way, 130+ traps speed from supercharged C63's AMG's is incredible. That this car did 134 on pump gas and full weight as well as the stock engine internals is jaw dropping.
