    • BigBoost's Stage 2.5 W205 C63 AMG M177 V8 turbo upgrade closing in on 7XX wheel horsepower - 689 whp dyno

      Big Boost USA continues to refine their turbo upgrade for the M177 4.0 liter AMG V8 motor featured in the W205 C63. Previously, without supplemental tuning, they managed 636 horsepower to the rear wheels.


      Well, after some tuning refinements they hit 689 horsepower to the rear wheel at only 19 psi of boost on 93 octane pump gas:


      The tuning is still a work in progress but we are talking about almost 700 horsepower to the wheels here.

      For $4670 this is definitely an M177 turbo upgrade W205 C63 owners should look into.

        Graph with RPM / torque available?

        On the 636 graph there is a graph with torque and RPM. I didn't measure torque on the last runs as it was completely assembled and it's pretty difficult to reach the ignition coils with all the covers.

        That makes sense.
