SpeedDriven M275 V12 Turbo Upgrade
has announced that they have a billet wheel upgrade for the M275 Mercedes V12 twin turbo. This upgrade is available for every iteration of the twin turbo V12, CL600, S65, SL 65 Black Series, etc. There are no dyno graphs available yet but we are wondering how they are doing this exactly. It has been said it is difficult to modify the turbos due to the turbos being integrated into the cast manifold. The stock turbos are K24 turbos which are well known in the Porsche world and often modified. We look forward to further details, the upgrade retails for $5990.
