You may remember the Dodge Demon. SRT"s unhinged, drag-racing ultra-muscle-car that spanks the bonkers 707bhp Dodge Hellcat into second-class citizenship of Muscle Car world. How? Well, it"s all thanks to 840bhp, 770lb ft of torque and some of the craziest drag tech ever put on a production car. And did we mention that it"ll do wheelies? For some, that"s not enough madness. People like John Hennessey, who has applied his we make fast cars faster" mantra by coughing some magic over the Demon"s 6.2-litre HEMI V8. Dom Toretto would be impressed. The most notable modification to the highest horsepower V8 engine ever produced is the fitment of a 4.5-litre supercharger, replacing the stock 2.7-litre system which was already bigger than a Hellcat"s. Strapped to a dyno, Hennessey squeezed out 880 horsepower and 806lb ft of torque to the wheels, translating as 1,056 horsepower and 967lb ft of torque at the crank, after factoring in Hennessey"s estimated 20 per cent drivetrain loss.
