Mountune offers a whole range of Ford-approved tuner packages in the UK that can make your Fiesta or Focus faster without voiding the factory warranty. Their latest power upgrade is for the Focus RS, bringing the total output of everybody's favorite hatchback to 370 horsepower and 376 foot pounds (for a maximum of 12 seconds on overboost).

For this whopping 7 percent of extra power, Mountune charges ?899, for which your approved dealer in the UK will upgrade the car with a high-performance air filter, bespoke alloy crossover duct with silicone hoses, an upgraded air re-circulation valve and revised software tuning for the engine ECU in just 1.5 hours.

Based on what I've gathered from Focus RS chief engineer Tyrone Johnson during the car's launch, the tunability of Ford's hot hatch is likely to be limited by it's drivetrain built around GKN's Twinster, which is an electro-hydraulic system with torque vectoring, consisting of a rear drive unit capable of overspeeding the rear wheels at a 1.8 ratio, with wet clutches on both sides and a separate cooler, connected to what acts as an open front diff with brake-based torque vectoring by a three-piece driveshaft.

345hp is what was deemed safe for series production, and 370 is probably within the design threshold. Anything above that feels like a gamble, especially knowning that Ford has broken quite a few prototypes before settling for these figures.

The good news is that the Ford Focus RS doesn't really need more power than its stock output. It's thirsty enough as it is.

Gonna be seeing some fried rear clutches pretty soon.

I wonder what that will cost to replace

Also it's only a matter of time before they figure out how to upgrade that rear end for maximum power

Given the AWD system on the FoRS (I did not know about it's low/stock only power limitations until reading this post), I would not be seeking much more power than stock, but would instead be looking to shed every gram of fat I could from one if I were an owner.

EVEN IF that co$t MANY times more than throwing power at it.

The Quaife front diff should have been standard on this car right from the factory, even if that meant a slightly higher base price.
But since it's not, that is one of the first mods I would do as an owner. ;)

TopGear - Ford Focus RS gets the Mountune treatment

"Ford?s official tuner turns RS up to 370bhp and drops 0-62mph time to 4.5 seconds"

5 Aug 2016 - TopGear

http://www.topgear.com/car-news/hot-hatch/ford-focus-rs-gets-mountune-treatment

untitled.jpg

The 345bhp Ford Focus RS isn?t exactly under-endowed, but that hasn?t stopped those talented guys at Mountune from making it even more banzai. Developed together with Ford?s Performance division, a new power upgrade package for the 2.3-litre EcoBoost engine takes peak power to 370bhp and peak torque on overboost (available for 12 seconds) to 376lb ft ? a 30lb ft increase over the standard car. Meaty.

With the RS? trick four-wheel drive system not wasting an ounce of that, 0-62mph is dispatched in just 4.5 seconds. That?s a 0.2 second improvement and now just 0.2 seconds shy of the Audi RS3, and that gets a fancy twin-clutch auto don?t forget, whereas the RS sticks with a trusty six-speed manual.

The upgrade includes an ECU flash, an uprated turbo recirculation valve and Mountune?s RS induction kit that includes an alloy crossover duct and high-performance silicone hoses to improve engine breathing by 11 per cent versus the factory fit pipes. Oh, and you get a Mountune badge on the boot to warn other road users of sudden and violent acceleration.

I understand that this is a strong little car, with MUCH potential, but WHY is everyone so gaga over it specifically??

(i.e.; completely forged bottom end, super/exotic car level SMG, best in the world AWD system, WHAT??)
I can't stand VW's... But after seeing an APR stage1 (intercooler, fart can, air filter, tune) got 12.0 like 12'times in a row while my buddies 370whp fost went 13.3 ( and 12.6 later on slicks ), I gotta say, the golf R is the real deal. And... Like all VW cars, it has a really really strong awd. VW has just never had an engine that didn't require a top to bottom build to take advantage of it, not to mention, they were always over weight. The golf R fixes that.

Besides that.... I really dislike VW's.

OF COURSE a street driven AWD car is going to out 60' and E.T. a street driven (NOT those TOTALLY UNSTREETABLE, 6 second, Honduhs which are ONLY usable for drag racing!) FWD car, even with less power, and even on just sticky street tires, given identical driver launch skills. [;)]

Which is one of the reasons I just don't get this chasing FAR OVER 300 WHP thing for the FiST, especially when almost NO ONE even bothers to do a proper diff as well, let alone a spool type solution if they are ONLY worried about straight line acceleration/drag racing).

It may be a strong AWD system in the GTI (Haldex??), but I'd bet it's NOT indestructible once they start throwing >500 AWHP at it.

Besides, I somehow do not think that ANY of the Ford RS cars were EVER designed with drag racing use in ANY of the engineers' minds AT ALL! ;)

I know that my FiST will NEVER EVER see a drag strip's launch pad as long as I own it, regardless of what BT setup (or none) it ever gets.

At this point, I dislike drag racing (yes, even test n' tune/time trial drag racing to see how much power is being made according to trap speeds) as much as you claim to dislike VeeDubs, as I feel that is NOT the venue these cars were designed/conceived for.

As said by M-Sports there is no reason to compare the R to the ST's regardless of power. You still have not mentioned one reason why the R is better than the RS besides being out for 2 years longer and having way more test and tune data to create your conclusion/hypothesis. I personally would rather have a S4 if you only want 11 sec 1320 times. Im just stating times like the R is producing is nothing that has not been done before.

Ford admits the rear diff is on the edge of reliability stock, and we are agreeing that the proven haldex VW awd is good or 500 or more awd...

Seems. Wait... I'm On a ford forum...
Fords the best ever with a 350hp car that has a diff engineered for 350hp, that's the best idea ever in a $40k car !!

Just simply saying that a DSG stage1 APR golf R will go 12.0 all night for multiple track days with a cat and on 93oct. And ford is saying that a tune is likely going to kill the the RS's read diff, lol.

The older EVO's and STi's were the same way. I saw so many EVO's go 13.2 with bolt-ons and then shit the trans or the transfer case.

I hate VW the most. But.... Credit where credit is due.

Not much different from an evo or STi really... But it's still BS.

Golf R ftw..
I think Matt Farah said it best "The Golf R is the most mini-GTR-like car out there today". Yes, the same man who owns a Focus RS. The Focus handles better, and certainly has the Golf R on fun, but if going stupid fast is what you want while still enjoying warranty and a nice interior then a Golf R is the best choice. Like said before, a Golf R with just a OTS flash, absolutely no physical modifications at all will run low 12's/high 11's (on some of the more aggressive tunes). Throw a $500 dollar DP on and you're in the 11's, while being comfortable and being able to bring the car in for warranty claims with little worry.

As for the comment on what makes it so great, well all the things you mentioned are mostly true. The new Haldex system is solid, the gearbox is bulletproof (6MT is too after you upgrade the clutch) and we actually have no idea what the engine is capable of holding. This is because no one has blown one up from making too much power yet. The big tuner, APR, in the VW world said they literally tried to blow the motor up on their shop car with repeated 500+ HP stress tests and failed. So it's safe to say they are pretty stout motor wise.

Wait an aggressive flash tune in the R is still under full warranty?
What I'm saying is that very few if any dealerships are gonna give you any trouble about a flash tune (which are undetectable unless they waste their time scanning the car on VW's), or an exhaust. If you've got a bunch of crap like a BT, Water-meth, Full-engine mounts, aftermarket IC etc. then a powertrain warranty claim is much more likely to get denied.
