Ford Focus RS Mountune MP350 package offers RS500 power for standard RS

So you own a Ford Focus RS and are pretty upset that Ford just released a hotter version of the RS with the new 345-hp Focus RS500. Worry not – Ford has just announced a new Ford-approved performance upgrade MP350 package that boosts the output of the standard Focus RS to 345-hp with a maximum torque of 339 lb-ft – the same as the RS500.

“Ford’s relationship with Mountune has produced a series of dynamic performance upgrade packages for Ford models like the Focus ST and new Fiesta, and we are confident that the Focus RS package will prove equally successful,” says Matthias Tonn, Focus RS500 Chief Programme Engineer. “While the limited edition RS500 we are unveiling at the Leipzig Show today will remain the ultimate Focus RS, this upgrade provides existing customers with the attractive Ford-approved performance enhancement option that many RS owners have been asking for.”

The MP350 package upgrade should allow the RS to hit 0-62 mph in 5.6 seconds with a top speed of 163 mph.

Hit the jump for the press release.

Ford Focus RS Mountune MP350:

Press Release:


* Ford-approved 350 PS engine upgrade for new and existing Focus RS owners
* Engine modifications developed in partnership with Mountune Performance
* Full testing and durability programme ensures no impact on standard warranty
* Upgrade available through selected Ford dealers, initially in the UK, with a European roll-out planned to follow

COLOGNE, April 9, 2010 – Owners and buyers of the current generation Ford Focus RS 305 PS superhatch can now access a Ford-approved performance upgrade package that boosts peak output to 350 PS and 460 Nm of torque.

The MP350 package is available from Mountune Performance via a selected network of Ford dealers, initially in the UK, with a European roll-out planned to follow. This is the only Ford-approved upgrade for the Focus RS and also the only aftermarket package available which does not invalidate the standard Ford warranty.

The engine modifications it provides are similar to those developed for the exclusive new limited edition Focus RS500 model and were developed by Ford’s Team RS powertrain engineers in partnership with Mountune’s performance specialists.

The Focus RS performance upgrade increases peak power from 305 PS to 350 PS, while torque rises by 20 Nm to 460 Nm. Modifications include a larger intercooler, a larger air filter box, a larger diameter exhaust downpipe and an uprated fuel pump, along with an updated software calibration.

Mountune also offers Ford approved performance upgrades in selected markets for the current Focus ST and Fiesta 1.6 Ti-VCT models, and the previous-generation Fiesta ST.

Mountune’s experience in motorsport and high-performance engines spans over 20 years and this strong heritage even includes the original RS500, as Mountune supplied the engines for the Ford Sierra RS500 Cosworth which won the British Touring Car Championship in 1990 driven by Robb Gravett.
