The 530bhp Focus RS From HELL!! 

The pops from the exhaust is glorious

Gorgeous Focus RS, thanks for reviewing it.

awesome I have been talking to the guys at devil developments last few days cant wait to get my rs in there 👍👍👍👍👍

Great video. I come from a family of ford's, and have a sapphire cosworth very close to me - as the name suggests. Exceptional editing, and very down to earth commentary. No BS in this. Please feature some older fast ford's in the future. I would love that. We are gonna be visiting Devil developments in the very near future with the Sapphire! All the best 👍🍻

That exhaust smoke nah

Looks like brilliant fun 😃 awesome car mate 👍

Great video, but next time a few more details on engine, like what turbo? what's been done to the internals etc. cheers

that looks crazy fun👍 think the fumes are to do with all that fuel being shoved into it, look at nissan gtrs they do the same thing cheers steve 👍 😀

Love it, looks like it kicks out some fumes though, decat I guess.

About time you reviewed a decent car 😅

drag vs your m140i

Tangmere West Sussex! Shout out to Freshlayers!

Careful the fuel light is on! I drive a 2 door stock 2016 Ford Fiesta ST white color RHD 93 386 Km on the odometer. Greetings from Pretoria South Africa 29 May 2021. Oh and I was born in July 1964.

mine has no fuel pump mods or uprated cams but does have all the usual bolt on mods and a bigger Precision NX2 turbo, the dyno registered 466bhp and 480 ft lb

Goals

what wheels are these? they look awesome and would love a set on my white focus.

Great vid Luke, devil developments are sickkk 🔥 that st is wicked 🤩 once again we’ll done m8 ❤️

Could we find out what you have exactly done to achieve this outcome?

😍

What is that rear wing gurney flap added on?? Really a perfect size!

will i get any benefit from upgrading the pistons on the stock block of an rs or not worth the rod upgrades?

ECOboost FTW :-)

Anyone else thinking this isnt the quoted power figure, its seems rather lathargic,

Was it a standard head ???

White wheels look nice, shame about the curb rash. Just a query, seems quite smoky under acceleration, what's the cause of this?

Too slow on acceleration not 530 lol, and the white wheels just look chav. Infact the whole car looks chav, and I have been an RS enthusiast from Mk 1.

So just fuel pump and injectors, no auxiliary injection? Which Turbo setup? Recommend for future such videos you share the dyno graph, so we can see the curve. I'd also like to see a build list. Devil Developments links to this video on their site, but dosen't list details of the car, anywhere. The only reference to "stg 4", is for a particular map, no forging, turbo, etc. Who puts in a LSD and clutch, but dosen't upgrade at least they syncos, if not the forks? Also, IMO, this car needs better brakes with this power. Owner mentioned going on track. Do they mean strip or circuit? That power, stock brakes on a circuit is a waste, like a super yacht, on a tiny pond. I'm also curious, for the street, what tire they're running, and if they have modified the torque output through the rear (via software), or if that is still stock.

Great power. But I would be really annoyed and embarrassed with that level of over fuelling at peak torque.

Is it running stock ecu? :-)

Luke I have one question. Are these brutal stock? 😅

ESP 😂 take it off

What did he say?

Revving it like that with 70.c coolant? 🙄 Let alone oil

Mine got the upgraded fuel pump and nx2 turbo and made 480hp and 608mn of toque I can’t see this is the power they saying it is and no upgrade breaks like I have on mine due to big power

Now he should have a race with his m140i bmw and see who would win

what wheels are these?

Looks a bit bore washy that 🙈

What fuel was he running?

RS not ST

Turned it off when I saw two of you goons with masks on in the damn car ffs.

Just found this from 3 years ago. Obsservations are a) this isn't a 500hp atw car (no e85 so not happening) b) it would have thrown a rod by now without forging and c) the stock 3-4 synchros would have sh@t themselves with the aftermarket Comp clutch

Still sounds like shit u can’t beat the mk 2 5cil sound

Still sounds poo!! 😂

Why are you wearing masks in a car together when you can't see? What's more dangerous.. RS Central!
