RE: New Mountune Focus RS upgrades
Monday 7th August 2017
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...
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...
New Mountune Focus RS upgrades
Products launched at Ford Fair liberate 400hp, with more to follow...
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.
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!
Discussion
I recall reading that tuners had been having significantly problems putting more power through the fancy rear diff (RDU) and as a result just had to put any extra power/torque through the front axle.
Anyone know if this is still the case or have Mountune managed to keep it nicely rear biased?

For all the extra cost and the fact you lose the Ford warranty, I couldn't really be arsed with this over and above the FPM375 upgrade. Sure it's very good though!
Losing the warranty with the block cracking issue they have must be a massive deal for any owner. Or was that an issue only limited to a few cars?jonosterman said:

According to some guy that worked on the gearbox project (software side I believe and testing..) the clutch pack that takes power from the front and sends it to the back has a limit to how much it can transfer.Anyone know if this is still the case or have Mountune managed to keep it nicely rear biased?
In simple terms if you try and put more than its capability through it, it just slips.
The standard car can meet the limit of the transfer clutch pack when software tells to it already, so anymore power cannot be transferred to the rear.
People challenged the specialist and mentioned adding in more discs to the clutch pack and he countered with there not being enough space and so on.
All in it looked like it would take quite a serious re-design to put more power to the rear than it already can when it wants to as standard.

Stupid thing to say. I was at Silverstone Ford Fair yesterday. Naughtily I was drifting about having the time of my life and pissing on mk2s whilst I was doing it. The mk3 is a far better car.
agreed - Mk3 is on a different level wrt dynamics and ability ...but the Mk2 is a far better looking car

Indeed a totally different league in terms of dynamics, fun and ability.but the Mk2 is a far better looking car
But imo the mk2 is by far the more silly, over top looking car which would work if it had 500bhp to match the looks but it doesn't and I could probably thrash one in my Megane.
Does that mean the Golf R is easier and more reliable to tune to 400hp - 500hp ?
I often wonder what the safe limit is on either with simple bolt on modifications. When you get to the point of needing to take the engine apart, you may as well buy a more powerful car to start with. It's cheaper and will last longer.

I think for the money (which I don't have) I'd get a mint blob eye or hawk eye Impreza, take it to RCM and have it done to 350bhp-400bhp. The GC8's they did (of which my uncle owned one) when done to those numbers would do 0-60 in under 3.8 seconds, speeds of over 186, torque figures of over 450 lb ft whilst sill being just as usable everyday, the figures are pretty much the same for the GD series (blob/bug/hawkeye). For £20,000 you can get ones that have had all the work done, you can get a Litchfield 420 hatchback for dead on £20K that'd see any new hot hatch left behind.

I think for the money (which I don't have) I'd get a diamond-encrusted Chiron with an automatic Swedish handjob machine built-in to the dash.Caveat: Just what I read on various forums and what "people" have said. A Google search will find plenty of opinions, and maybe even the occasional fact.
From what I gather, the block problems are caused by the V4 castings being 'bad'. The V5 blocks are fine. I seem to remember it is to do with insufficient metal around one of the head bolt sockets which causes it to crack, and hence lose coolant and all the rest that it entails.
