Tuner Cranks The Ford Focus RS Up To 513bhp

Mountune's new m520 MRX tuning package for the Focus RS sees dramatic increases in power and torque
Tuner Cranks The Ford Focus RS Up To 513bhp

Ford may be finished building the third-generation Focus RS, but the car’s story is far from over in the aftermarket world. Mountune, for instance, has launched two new tuning packs for the all-wheel drive hot hatch.

The first of the Essex-based company’s pair of options is called ‘m450’, which centres around a BorgWarner EFR-6758. It’s a ceramic ball bearing turbo, which means it should be nicely responsive and not bring with it big dollops of turbo lag.

Along with the EFR, m450 also includes a cast turbo adapter, a freer-flowing catalytic converter and downpipe, and a compressor outlet/inlet elbow made of five-ply silicone. With all that fitted - something MounTune will do for you - your RS will be good for 444bhp and 428lb ft. If you’ve ordered a new Mercedes-AMG A45, it’s time to be afraid.

The standard Focus RS is hardly lacking in the firepower department, but if you want more go, Mountune has a few options

For anyone wishing to go beyond those figures, there’s the m520 package to consider. Much of the m450’s parts are retained, but the turbocharger is switched to a BorgWarner EFR-7163 unit. You also get an upgraded fuel pump from Xtreme-DI and an uprated valvetrain including revised camshafts.

Have all that fitted, and you really will have a hot hatch to be reckoned with. Working together with a recalibrated ECU, the changes see the 2.3-litre inline-four’s power leap to 513bhp, and the torque balloon to 516lb ft.

Interested? The m450 pack is £2950, while the m520 is £5,974.99. You will need to strengthen the 2.3-litre Ecoboost engine’s internals before fitting either, Mountune says.



Thats a mountune of power you need to focus on

So 30,000 pounds for the car itself and then 6,000 pounds of upgrades makes 36,000 pounds. 36,000 for a 500BHP car. Wow.

Remember, montune says you have to supply the supporting mods before getting the package. So its not really l500bhp for €36000, is it?
