A group of Ford tuning specialists at Mountune have announced two new kits for the Mk3 Focus RS which turns the four-wheel drive hot hatch into an unstoppable beast. The first kit is a 450HP upgrade that adds a BorgWarner turbo, with dual-row ceramic bearings to allow the turbo to spin up faster and last longer, and the fitment of new high-flow sports cats and downpipes. The torque for this 450HP kit reaches 580nm which is a 110nm gain over stock. The larger upgrade kit provides 520HP with an uprated fuel pump, revised camshafts, a new ECU calibration and a more powerful BorgWarner turbo that, collectively will make 700nm of torque, which is 50nm less than the Audi RS6. Truly insane from a hot hatch!
