Project Fiesta ST - Cobb Stage 3! New Exhaust Sound + Dyno! 

I hope TST is getting some commission for all the Fiesta ST's they're selling for Ford.

Man. Mcgyver the rear subframe from a escape or fabricate one and use a gearbox from a Ford Escape awd as well as a rear differential and see where it'll be at. So much torque from that engine makes me think there's more in common with the rally car than it meets the eye. Even the way the engine sounds makes you think of the WRC car.

Did you do a video with your Stage 3 Fiesta ST on The Snake? You should if you haven't yet.

on my BMW 135 I gain about 60-80 hp with just a Cobb stage 1+ (with intercooler).

why do u hold the on button ? what does it do for the launch?

Does anyone happen to set a 0-60 time with this stage?

E85 or Meth if California doesn't have any E85 stations.

Its decat?

These videos make me want a Fiesta ST so much.

I prefer small fast cars like fiesta ST over fast big heavy cars,

The exhaust mounted mic sounds kinda weird, windy and it also sounds like it has a lot more gain on it than it can handle, is that true or am I just being a bit of a moron? xD

wow americas getting some proper fords at last

This would be considered a stage 2 in the Subaru world. Isn't Stage 3 an upgraded Turbo, injectors, intercooler etc etc? Stage 1 just being a tune? Anyways, that's not bad gains, She has a torquey engine for an inline 4. However the hp is nothing to write home about. With numbers like that, at least she's a lightweight compared to the WRX's & Evo's out there, however I don't think this car would fair too well against either of them (assuming they're stock)

Why does the stock horsepower keep going up every episode. Lol. First video stock was 185whp/230wtq and Stage 1 was 187whp/246wtq. Second video stock was 189whp/236wtq, stage 1 192whp/256wtq. Then in the Protune video it made stock 191whp/236wtq So did you re-dyno the vehicle with the stock tune and stage 1 each time or what? Too much variation in numbers.

2:28 - My face the first time I drove my ST.

Pops and Crackles make my life

I drive mine bone stock with a grin from ear to ear anyway. I think the car is plenty fast out of the box. Fast enough to kill ya for sure

For the money spent on the stage 3, week sauce on the hp gain......

Makes me wanna buy a fiesta now....!

Yeah the exhaust audio recording SUCKS!

i do like the gains. but hes right. getting some real numbers like 0-60 improvement over stock, track time improvement over stock, even a 1/4 time would be nice to see. Hell, even do the 30-60 test in 4th gear that mountune gives to show their products improvement. at this point its definitely mountune vs. cobb for the premium fiesta st tune company. I would love to see a mountune mp215 fiesta against a stage 3 cobb fiesta in a series of challenges (using my jeremy clarkson voice).

I got my 14 Fiesta ST right after I saw this video, I’m stage 2 Cobb, short shift kit, bigger intercooler, it has 87,000 plus miles on it and it runs 💪🏼 Strong as ever, I’m on my 5th set of tires, so fun to drive fast, Street legal go kart. The Fiesta Flash 🤙🏼🍺🍺

dude!!! that thing sounds like ken blocks gymkhana fiesta!! bad ass! i love it!

I feel like you'd love a Mazda speed 3, just a few little things like a front mount intercooler and a tune, you'll be making 300+whp. This little unit is awesome though, it seems to respond to upgrades very similar to the speed 3.

TheSmokingTire Hey Matt, when do we get to see you take this thing on a canyon/track review?? It would be awesome, especially if you pit it up against something more expensive (& stock) with a similar bang for your buck style ;)

Time to up the fuel rail and pump. Also, lets get some meth injection!

Matt you fucked up here, you are quoting the figures after the stage 1 remap as the stock figures. The stock figures were actually 230WTQ 185WHP. So in fact the car has gained 32WHP and 57.4WTQ...

Man if this is ANY indicator then those eco-boost Mustangs are going to fucking slay demons.

What was the cost of the parts? I am interested in the hp/$ ratio...

Matt, Hi. Hopefully you would respond. How you liking your rolex?

1st video: stock is 185hp 230tq, stage 1 is 187hp 248tq 2nd video: stage 1 is 192hp 256tq, stage 2 is 210hp 272tq 3rd video: stock 191hp 236tq, stage 2 is 210hp 272tq, stage 3 is 217hp 287tq interesting lol

Motor mounts are such an overlooked mod these days. So cheap and simple to install. I consistently dropped a tenth at the drag strip just from upgrading the mounts.

I stiffened the motor mounts on my first 93 Accord Made the car vibrate a little at idle, especially with the A/C on... but man, that shift from 1st to 2nd could chirp all day with like a measly 160-170 crank HP. Definitely a worthwhile mod.

So what happened to the Mustang project?

0:35 half of a second of thinkng "OH SHIIIT!"

That clunk of that motor mount scares my buddy who has had manuals before, I'm coming close to 6k miles on mine I might have to look into this mount soon, maybe the rest of the stage 3 later :-P

This chassis lowered on coilovers one of the best handling cars i have been in. Just goes where you point it most speeds (depending on tyres)

Cobb Stage 3 isn't a three part salad for the theatre. Came for antipasto, left disappointed.

Please, do not compare a fiesta, to a E30. Thats just wrong.

Really looking forward to those future updates of this thing. Not sure I'm completely sold on that exhaust note but those gains look nice! Has Cobb slated where these stage kits are going to be in terms of being CARB friendly? I imagine a new filter and a chip will be fine; a down-pipe not so much.

I was expecting on a stage 3 tune 230whp. But the exhaust sound made up for it! Love it!

I got a kid running around in a fiesta st and a pizza delivery guy runs a focus st. I really like how ford placed themselves in the "hot hatch" class. Even my wife's regular 2012 Focus with handling package is fun to drive. 217whp/287wtq with boltons + tune? Pretty good stuff. I'd love to see a 1/4 mile run down the line. And it seemed the exhaust sounded so good that the poor microphone got overwhelmed.

yep.....dyno is only one half of the story.....now get some 1/4 mile times and road course lap times....find someone with a stock car and compare it to this stage 3 car and I hope to see a decent turbo installed!!

Loving this series, Matt! Appreciate you and the film guys doing it. That ST is one awesome little hot hatch now.

Matt, why the differences in the reported dyno results from video to video? Stage 1 Video Stock - 185/230 Stage 1 - 187/248 ------------------------------ Stage 2 Video Stock - Stage 1 - 192/256 Stage 2 - 210/272 ------------------------------ Stage 3 Video Stock - 191/236 Stage 1 - Stage 2 - 210/272 Stage 3 - 217/287

Hey bro can you help me with cobb stage 3 map I need that file cobb does not have any more but you in your cobb garage are still able to download it since you had it before. Help please

So this car makes 191whp stock? I find that hard to believe as the stock bhp is 197hp to the crank. Sounds like a happy dyno to me.

I wonder is it about time for a LSD for the torque and wheel spin

with that much more torque I got to ask how the if there is any torque steer, can't wait to see how it does in the canyons.

Holy carp! Matt you keep getting thinner! Keep it up buddy!

While not a world beater in numbers (the Cobalt SS made that off a simple tune), this is a much more efficient package than the Focus ST and would be a ton of fun to drive. For ought to be paying you guys considering how well you promote their products indirectly. I'm tempted to trade my daily driver Ford Escort ZX2 S/R in for one of these. Much as I want an 03/04 Cobra Terminator, this is the better option by a longshot.

In 1986 I jammed a Chevy 350 small block into a Vega 72 GT . Does anyone know if its feasible project to put the SHO twin turbo Eco Boost into the Focus or new body Mustang ?

Assuming drivetrain loss is 15%, this means the little ST is making 250hp & 330 ft.lbs of torque (!!!!!!) at the flywheel. What a little monster :)

So , in US for manufacturers it is ilegal to have exaust without catalytic converter , to be louder above certan point . They are so strict that many Europeian or Japanese cars ( small and economical ) like kei cars can not be imported to US due to safety , noise and polution regulation . But it is legal to cut stock exaust out and replace it with loud pype on brand new car , to have 2 supercharged engines with no exaust on pre war chasis , to drive around with no seatbelts and to use more uncalatized fuel on race day than my whole country uses in year . You Americans are so power obsessed . Yesterday there was debate should FIAT make Abarth 500l and many sugested that it would too much power if it had more than 170hp , but stock 500l has 160hp in US .

Custom tune it already...beware of those Cobb ots maps. MY TUNER SAYS THEIR ENGINE TIMING IS MURDER.

So now we are at $3500, 2500 for the kit 650 for the ap v3 250 for the tune 100 for the dyno time, Not including cost of install. I like how the stock HP keeps changing in every video.So for this much money you got 25hp WTF.

I hope it's just the video audio.. because honestly, the new exhaust sounds way too intrusive. It takes the 1.6L and makes it sound like a chainsaw. Again, hopefully it's just the video audo.

That is just not impressive at all. I think the fiesta st is a neat little car but it is so far from a performance car. It is begging for the 2.3 ecoboost engine at least. My commuter car, 2015 avalon, would pull on this. And that isnt right for an ST badge. The turbo may just need an upgrade in the fiesta to make any real gains, but i doubt the block could handle more than 300whp

What's the 0-60 mph withe stage 3 and launch control?

The Smoking Tire Matt, I'm about to buy a Fiesta ST, can you comment on how all the mods affect the cars daily driver characteristics? I plan on driving this at least 70 miles a day to work and back, so fuel economy is also important.

The Focus and Fiesta ST both have the soft motor mount issue. The engine smacks the firewall bone stock on a hard 1-2 shift. I'd consider the motor mount upgrade part of stage 1 or stage 2. Other than a tune, it was the first thing I did to my Focus ST.

this car is going to be my first buy! im gunna have the cobb stage 3 with an atp stage 1 turbo.. some 255's (hopeing they can fit).. coilovers.. 1 inch smaller wheels but same diameter tire.. and some wilwood brakes... because god i hate the look of the calipers on this car.

For all that money I would have just made it lighter... reduce unsprung mass and anything that can bolt off.. for a 26hp boost thats pretty shitty....

So everything that used to be absorbed by the motor mount is now damaging the whole mechanism of clutch, gearbox, diff, axles and joints. Cool. Sorry, I just hate tuning :)

Why doesn't Ford make a version with AWD? Ken Blok's Fiesta is the only reason it became so popular....If they are making a legitimate compact turbo I don't see why not

Hey i know its old video but i have 16 fist now and im 38yr old . Is it reliable and i wanna get more power about 100hp eventually

The mountune kit offered by ford would have given you similar figures and only costs £499 fully fitted by Ford themselves without affecting any kind of warranty

This definitely isn't stage 3. Stage 2 is all of the parts here really, this is 2.5 tops. Stage 3 is an upgraded turbo, and in the UK that is pulling 260 - 280bhp.

TheSmokingTire Did you get a check engine light come on in any of the stages? Did you notice while idling with A/C on because of the motor mount it shook a little? And also did all these mods void the warrenty? I just got a fiesta st and am looking into the cobb stuff. Love your page!

How much is it for a full stage 3 overhaul like in the video and where are you based? I have had a Fiesta ST for 4 months now and love it,but it defenitely could do more easily. Feel free to message or e-mail me specifically if you dont want to post the info here,it is appreciated-thank you

So what does Stage 3 give you as far as performance gains? I see 217 HP, but what does it do 0-60 and the Quarter mile in ?

I love you guys but you really need to invest in either a better microphone, or a guy who knows how to record/monitor sound. That's really the only thing that other car channels have on you, the car's exhaust/intake just doesn't sound very good. Love you though!

Stock numbers don't match original video. Regardless, so much bang for buck with this car. must have.

Do you guys think you could add a comment in the description or even during the videos on a ball park price on how much these upgrades should cost? I know prices very market to market and especially car to car but even a ball park estimate would help people figure out if they're over paying or going in the right direction.

Damn Matt you couldn't clean yourself up a Lil bit? Show your employer and viewers a Lil professional courtesy

The RMM was a huge upgrade on my FiST. This should be the first mod any Fiesta ST owner should do...even right off the lot.

Not too sure how the new STI is considered ugly by many when nobody really talks about how unattractive the ST looks. I know it's a minor detail but thought i'd throw it out there.

ford racing have got the 1 litre ecoboost up to 300 bhp. that's mad for a 3 cylinder engine. pumaspeed uk have got the 1 litre up to 215 bhp. but you'd have to throw a couple of thousand at it to get it up to this power. pity you can't get the three door versions in the states. still a beast of a car

I'm a Vette guy and all but damn doesn't that sound good. Reminds me of rally car sound. Not ricy like i expected.

My guess is the car didn't make much power because its not full tbe 3". Tube diameter is not much different than stock.

What do they need to do to it to make it hold that torque? Turbo? Cams? To me a 25hp gain isn't enough for the amount of work that's gone in. When it's on the dyno you can hear it start to pull then the torque tails and it just sounds like it's struggling the whole rest of the run.

That's not enough of a power gain to justify spending $3k, sorry.

Is it just me or does that sound meh? How much does all that cost? Worth the gain? I guess the track/canyon videos will tell.

take it to a mustang dyno.u will not see over 170whp and thats its real power.sorry i m a big fan of u and your videos but this dyno is way too fake!

TheSmokingTire my FR-S is quietly sobbing in the driveway...

5:29 Ricer fly-by, and go figure its a Honda!

You can get mountune tuning in euro, stage 1 212 bhp 6.6 seconds I wonder what stage 3 would be over here

Hey smoking tire did you guys do a custom tune or just a pre loaded tune from a v3? Thanks!

Livernois OTS plug in tuner blows these numbers out of the water for less than 5x the price.

Honestly from this video, I don't like the sound. But it probably sounds a lot better in person.

Sickkkk this lil hatch is fast as fuck! Lets see an update on ur mustang

so fiesta or focus...they're around the same price, what would you get to live with?

Im sure this car is quick and handles good but I still dont see the appeal. Look at it. Its fugly as hell.

The car sounds now annoying to me.

that'd be stage 2 in uk, my fiesta ST is currently running a revo stage 2 map with airtec intercooler, itg induction kit and milltek turboback exhaust and that puts out up to 240bhp, stage 3 would then be a hybrid turbo and stage3 intercooler. I've heard loads of good things about the cobb mount and have ordered mine, just waiting for it to come as the thumping noise really is a cringe and struggling to put all the power down to the ground

how do you activate the launch control I've the same car and modification with accessport v3 and i don't know how

That motor mount is also very very good on the drivetrain. That movement is horrible on the transmission.

Haha I bet it was a honda making the same power and noise every body would be saying rice.

Usual ford quality motor that knocks into firewall under hard acceleration

Looks suprisingly roomy. Or maybe Matt is shrinking.
