November 13th, 2014

McLaren-650S-dynoFabspeed recently dyno tested the all new McLaren 650S before working on tuning the car for additional power.  The McLaren 650S is powered by a 3.8L V8 Twin Turbo engine producing 641 HP through a 7 speed DCT transmission.

On the DynoJet the McLaren 650S put down 569 horsepower and 451 ft-lbs of torque to the wheels.  This is 52 horsepower more than the 2013 McLaren MP4-12C they tested on the same dyno earlier.

After some tuning and exhaust work to the 650S,  Fabspeed was able to increase the power to 620 horsepower and 509 ft-lbs of torque to the wheels.
