You'll know by now that Mountune has a great reputation when it comes to fast Fords; new or old, turbo or naturally aspirated, the results speak for themselves. And at this year's Ford Fair (which took place yesterday), Mountune has released details of its latest M400 pack for the
Focus RS
Hopefully Monday isn't that much of a struggle to realise what that means for power, this upgrade building on the
MP375
kit released last year. Like all Mountune upgrades this one is modular but, if you have 375hp already, the kit comprises a new intercooler, a high-flow hard pipe, a three-inch downpipe with sports cat, a three-inch cat-back exhaust, a pair of Mountune badges (good for 20hp at least), and the mTune handset with the 400hp map. The mTune also allows a switch to standard calibration, a dyno mode (if you're only on a 2WD rolling road), a shift light and calibration updates, plus it can log 0-60 and quarter-mile times too...
Mountune says this is sufficient, with the standard turbo don't forget, for 400hp and 413lb ft. The M400 kit is described as "undoubtedly the most well-rounded performance upgrade available", drawing on Mountune's "unequalled" knowledge with the Ecoboost 2.3 and its limitations.
And if you want more than 400? Well new parts are in build also, launched again at the Ford Fair. A cast inlet manifold, for example, "recommended in applications surpassing the OE plastic components' design limit of 400bhp (406hp)". Beyond that Mountune now offers forged pistons, forged rods, a closed deck block modification, a gearbox upgrade and more. 500hp could be fun...
Mountune parts for the Focus and Fiesta ST were launched at Ford Fair as well, if you're a fan of Blue Oval hot hatch fan, it might just be worth checking out the website. Caution: it may get expensive!
