Since we’re still a few months ahead of the market launch of the almighty 300HP Focus RS, Ford’s UK division decided to offer an optional performance package for the Focus ST. Developed by Mountune Performance in association with Ford Team RS, the performance package consists of a larger intercooler, a high-flow air filter and revised engine calibration. Together, this lifts power output from the ST’s 2.5-liter turbocharged 5-cylinder engine from 225 HP to 260 HP at 5,500rpm and maximum torque from 320Nm to 400Nm at 2,500rpm. -Continued 
According to Ford’s preliminary specs, the performance upgrades reduce the Focus ST’s 0-60mph (96 km/h) sprint by 0.6sec to 5.9sec, and the 0-100mph (160 km/h) time by 1.9sec to 14.1sec.
The optional performance pack will only be available at selected Ford dealers around the UK from Sept 2008 with retail prices set at £1,120 or $2,000 / €1,400 but you’ll have to pay extra for fitting. The upgrades carry a minimum of 12 months/12,000-mile dealer warranty up to a maximum of three years/36,000 miles and as expected, the upgrade kit does not affect the vehicle warranty in any way.
