Krzysztof Ćwiertnia from Custom 166 Racing built his unique 1966 Mustang after being inspired by Ken Block’s Hoonicorn. When we shared the project three years ago, it was powered by a twin-turbo Chevy V8. Since then he swapped back to a Ford power plant. It is now powered by a turbocharged 5.0 L Coyote V8 with Manley forged pistons and rods, upgraded injectors, and a single JRspec GTX45R turbocharger. The Mustang made made 913 hp and 1100 Nm (811 lb-ft) of torque on the dyno thanks to Tuned by Niuton.
