Credit to Labworx Development who kept at tuning this monster setup. You will remember this W205 C63 was at just over 700 horsepower to the wheels on a Mustang dyno previously. Well, it is now at an incredible 778 rear wheel horsepower.


That is a ton of power and the twin GTX3071R turbochargers are doing some serious work:


Kudos to tuner @kbaldi29.

It is not just a dyno queen, either. 60-130 comes in a stellar 6.18 seconds:


Keep in mind this is not done yet. We will see these turbos and the tune evolve with various fuels and as the owner puts more miles on the setup.

A next level W205 C63 M177 though with much more to come.
