New Car Ford



  Fiesta ST Stage 3
Over the Christmas holidays I managed to get a few more things done on the car and do some service work .


The car has just come up to 12000 miles .


First up was to clean the ITG air filter as it has not been cleaned in over a year .


Old dirty looking filter

Clean and oiled ready to go back in

Then a quick engine flush and an oil and filter change

I replaced the spark plugs for new ones

With this little lot done I started on installing some new bits on the car


First up was a Mountune Roll restrictor

New vs old

Then I set about changing the boost pipes for some Mishimoto large boar ones .


The Hot side pip is a one part unit so less chance of boost leeks and is much larger at 2.5 inch

The cold side is again larger at 2.5 inch

Installed

I wrapped the cross over pipe with heat reflect tape as this sits just over the turbo and does heat soak and gets warm to the touch .

Then on to the last job fitting the Boomba inlet manifold and throttle body spacers .

With the Inlet manifold off this was a good chance to have a look at the valves .

The car has done 12000 miles and they have a fair bit of gunk on them so I gave them a clean ( I have done this on my old 208 GTI so have a few techniques for this )


12000 miles of build up

Much cleaner

It’s by no means perfect but much cleaner than they were and not bad with just some simple tools .


Inlet manifold spacer installed with some extra sealant on the ports just to be on the safe side .

Throttle body spacer installed

Everything installed and put back together .

What's the idea behind the spacers? Reduced heat?
Reduced heat transfer I believe. Surprising how much it works, the PTFE? gaskets someone did for the F4R engines at one point made a huge difference for the inlet manifold. Could still touch it after it had been running for a while without loosing your skin.

Smooth out air flow and add volume to the inlet manifold and throttle body .

The inlet manifold is plastic on the Fiesta ST so i do not think it gets that hot its more to smooth air flow and add volume .

So next up and to finish the car off I have the car booked in to Devil Developments on the 06/02/18 to have a Quaife ATB LSD fitted along with new bearings oil etc .

I will also be having the car lived mapped with there custom stage 3 software and a RR session done to make sure everything is ok .

I have also just ordered a Whiteline rear anti roll bar and powerflex rear spring cup bush along with some new super pro front droplinks .





And to finish off iv just ordered the Mountune club sport suspension .

I think this will just finish off the car nicely and will be just how I want it .

The diff will be so much help to put the power down as with the weather its hard not to spin up the wheels unless you are in a straight line .

Nice little shopping list that, will transform the car!

I've had a Quaife diff fitted on my GP2, it's so good.

Came across this and not my cup of tea at all regarding the car and the driving on public roads but was interesting seeing how a hybrid fiesta ST goes vs an A45 AMG standing and rolling .

He's a good 60bhp up on you though isn't he?

The car in the vid is running the AET VT330R so around 320 BHP my car is running the Collins CP4X and put out 269 BHP at Surry rolling road ( running an out of date and low power gen 1 map I am told ) so yes that car is running much more than my one but gives a good account of how 4WD and LC give a big advantage in the A45 and how quick the fiesta can be with some bolt on parts .

I managed to install all of the suspension upgrades at the weekend a nice and easy job and one step closer to the car being finished off .

The upgrade parts are Mountune club sport suspension ( bilstein B8 shocks and Eibach / Mountune springs ) Powerflex rear spring isolators , Whiteline rear anti roll bar and superpro front HD adjustable drop links .

First off was how the car is on the stock Ford suspension that is very good from the factory and the car handles amazingly on this OEM set up but as with everything it can be improved .

My car is a 2016 and is running the Fiesta ST200 revised suspension ( information in the below ) with changes being a thicker front ARB and a stiffer rear torsion been set up along with revised shock and spring rates and quicker steering rack .

Apparently It seems there was some concern that the back of the ST was too aggressive, so Ford stiffened the rear torsion beam by 27%, fitted a thicker front anti-roll bar (21mm instead of 19mm), and recalibrated the steering to match.

These alterations then allowed the engineers to reduce the spring and damper rate by using new front springs and dampers and new rear dampers (using the same springs), making the ST200 softer and better able to deal with sudden bumps and camber changes.

Apparently, as Ford couldn’t justify the expense of sending two different chassis setups down the production line, it started to put the suspension changes onto the standard ST (apparently from 13/8/15) without telling anyone, as it didn’t want to ruin the ST200 surprise.


Stock set up and ride height











First was to install the Whiteline rear anti roll bar





Then remove all of the rear stock shocks and springs and spring isolators





The stock shocks and springs were all in good nick


The rear spring isolators are made of foam and are very squishy and do brake down very quickly .








New mountune springs











Rear Bilstein shocks





The rear installed








Super pro front drop link








Front Mountune clubsport kit and old shock








And all installed





I ran out of light to take some pictures of how the car now sits but will update this later

Not very scientific, but impressive how the Fiesta pulls really. Shows how quick they can be.

The video was deeply irritating though 😂

So how does the new setup feel compared to the revised oem setup?

The car is still on the drive way and I have not driven it yet as im away with work this week but will have a good test at the weekend and report .

Correct me if I'm wrong, but does airflow really matter when it's compressed? And surely more inlet volume equals more lag.

The car does not have anymore lag less TBH and feels more keener so the smother air flow must be helping and with the bigger turbo more volume must be helping .

Seen a few RR graphs with this mod done in the USA and all have added torque and power more so on a hybrid car .

Fair enough chap:up: the science does say it would have more lag (whether you notice it or not) because there's more air for the turbo to compress.

TBH I really cant feel any more lag but the trade off then with the more air would be more power and torque is my thinking .

Thanks it is getting there and will have another go when there is the next Clio RR day .

The car is in next Tuesday for a ATB LSD and different softwere .

Lovely project thread mate, and a cracking little car!

Looked and sounded the part at the rolling road day also! :up:

Yeah I bet mate.

Fitting a Quaife to my Trophy was the best thing I ever did. Even over the supercharger!

On track it just makes an already very exploitable car even more potent.

Something I can only assume will happen also to your ST!

So I have given the car a little test over the week end but as its been so cold have not had chance to push it in the corners .



First impressions are that the car is a little bit stiffer and more firmly sprung going over bumps than the OEM set up but is no more and TBH less crashy over bumps and ruts .



Body roll seems to be even less as well .



A few shots of how the car now looks .



OEM set up







New set up











I will see how this settles down and how it feels in the corners but the ride height is spot on for me as I did not want too much of a drop from OEM to keep in the very OEM feel of the upgraded car

Last week I had the car go in to Devil Developments for them to fit the Quaife ATB LSD along with new bearings , gear oil etc.





Yesterday with the roads not covered in salt or water and with the temps not a –1 I had a little test of the diff to see how this has changed the car .

Blown away is the best way I can sum it up the grip the car now has is amazing and the car can now put the power down and just fires you out of corners like you would not believe .

Where before you would have to come off the throttle you can now just pin it and the car gets dragged around the corner and silly speeds .

I would say without a doubt it is the best modification I have ever done to any car and left me shocked at how much of a difference it has made to the car Utley Utley amazing bit of kit .


I also got them to add there custom live map to the car using Evolution chips software as I have heard nothing but good things about them .


The car was running the Collins stage 3 software and did 269 BHP and 269 LB/FT at Surry rolling road in October .





I have from the last rolling road installed some Mishimoto big boost pipes and a Boomba racing throttle body and inlet manifold spacer and an engine service oil filter , new plugs , clean of the ITG induction and a deep inlet valve clean .

The above along with the new map on the car the car made 305 BHP and 320 LB/FT .





Looking at the two graphs that is a peek increases of 36 BHP and 51 LB/FT and the car is making more power and torque of around 38BHP/LB/FT across the entire rev range .


The car was running great with the old set up and was a very quick little thing and in Germany last year was happy to sit with a MK3 Focus RS but even in this tune grip and traction were always a problem but now it is alarmingly quick at putting speed on .


With this new set up of the Mountune and other bits on the suspension the Quaife ATB LSD and the new map the car is now just how I wanted it and is by far the quickest thing I have ever owned and down a back B road is so much fun and scary how quick it is but at the same time looks , sounds and feels very OEM and very stock .


I will be off to the Nurburgring in August and can’t wait to see what this car can do there .


The only last thing that will need upgrading will be the brake pads as the stock ones do have some fade when pushed a bit

:up: That's on my doorstep as it happens

Ok I will look you up next time im there .

300bhp from a 1.6 engine with standard internals - mental. Must be a rocket this.

You can get even more as my car has the X47 hybrid turbo and all safety systems still on and the car is running a sports cat and two exhaust silencers .

With the AET/VT330R or the X47R hybrid turbo and full exhaust and de cat around 340 BHP possible

All on the stock engine and with 45 MPG still easy to get .
