John Hennessey and company think that they can get even more out of the McLaren MP4-12C than the engineers at Woking. Usually this simply involves bolting on a pair of massive turbos and hoping for the best but the MP4 already has twin turbo’s. So what did they do? Yup you guessed it, put new ones one with upgraded intake, intercooler, exhaust and transmission. They have made the car look a hell of a lot more impressive with a new CarbonAero body kit and deep wheels. Results are promising indicating the car will reach a monster 800hp which is a massive hike from the standard 592hp. So if you do not think that your McLaren is quick enough, pay the boys at Hennessey a visit!
