601 horsepower naturally aspirated M156 / C63 AMG package from Wimmer Racing - 19,900 EurosWimmer Racing has released an upgrade package for the C63 which takes the M156 V8 to 601 horsepower. They achieve this figure through a head and cam package. In addition, they modify the headers, intake, and the rest of the exhaust along with a tune. This is a pretty expensive package and there are no dynos or performance numbers to support the claims.
