Modifications to the Ford GT include a pulley, tune and exhaust that put down 651HP on a DynoJet Dyno.

The 2015 McLaren 650S comes from the UK in stock form with a twin turbo 3.8L V8 putting out 641HP.  With 10 years between the model years there is a lot of new technology in the McLaren that the Ford has to compete with, most notably the 7 speed dual clutch transmission with lighting quick ignition cut shifting.  The Ford GT uses an old school Ricardo 6 speed manual transmission.

With almost identical power to weight ratios you’ll see just what wins the race and why.
