Time for a build thread....big turbo

WMI could play a part as well.
True,but it never runs for long.

Comes in at 0.5bar,and tops out at 2bar,so it would take a long power run to make a big impression with WMI alone.

I think basically the thing isn't over stressed,the huge turbo and exhaust result in lower EGTs than the old K04 etc etc and it all adds up.
 
What EGT's are you hitting? Wondering how it compares to mine. I can't actually remember the group I need to log, is it 112?

Without a proper EGT sensor the S3 derives it from lambda probes IIRC.

I'll check when I get a chance but on the old setup it never hit much above 800c on a run.

I'd not want to see what ALS does to it.
 
Alex, regarding the exhaust have you considered an exhaust cut out, the americans like to use them.

The gases go through your restrictive exhaust system under normal conditions but when you want to unleash the power the dump opens.
You can set them up to switch in the car, others have a mechanical actuator and can be set to open at a set boost level or you could no doubt control it with an output from the syvecs to open at a certain RPM/boost level

I know its not your usual thorough way of doing things but its another option
 
Hi Antwan....

AMD can do a similar system for me,but it's really the diameter of the current system that's the big problem at 70mm.

I've been recommended a 90mm system instead.

I'll certainly take a look.

The cut out dumps the exhaust at the bottom of the down pipe, unless you mean you need a 90mm downpipe

Ahhh I see.

I need a 90mm system from the downpipe back.

i see where this would fit and work but it would be hellishly loud.
 
Its for "off road use only" of course.....

The big horse power guys stateside swear by them, i.e. they can run on the street with modest boost through the (quietish) exhaust system, then head to the track, open up the cut out and unleash the power

LOL......like our decat systems over here.

BCS have offered to make a custom 90mm system with their Powervalve system,plus a 120mm FIA race cat,so the frontal open area of the cat equals the pipework diameter.

I think I will probably go with this option as I'm pretty sure the back box on my current system is blown already.
 
I guess it wasn't cheap,but I was fed up having the top end cleaned out,and a conventional catch can won't catch it all.

The downside to this system is emptying the can on a regular basis,and a couple of other issues over fitting,which meant the carbon filter was relocated,to make way for the can.



It also smells a bit of hot oil after a hard run....

Alex, Where did you relocate coal canister? Inside bumper? I'm making custom OCC, I need big like this and this is the only place where it could sit!

You mentioned TTRS LPFP - I have one from RS3, it works perfect with REVO 4 software, no adjustment was needed. Few more kilometers with rebuilt engine and I'll tell you if it's good for engine running on 2 bar boost :)

Hi there.

The canister was relocated in the left front bumper space.

I was recommended the RS pump as the fitting are all correct,and Storm have already done some work with it on one of their own cars.
Running it via the Syvecs should be straightforward enough.
 
Hm, left as english passengers side or drivers side? :)

Lol.

Ok English passengers side.

Would be possible no doubt to use the other side if more appropriate.

That's why I asked this question because that side is nearer than left side :)

I think it was chosen on mine because we'd already used that area a while back when I had an old Forge CAI,and using the left side again seemed logical.

If the same space exists on the right,then it may be a better choice for some people.
 
I have an exhaust cutout on my system..

I also have a screamer pipe.
It all helps minimise the restriction of the exhaust.
Steve
 
Nortech have come up with an exhaust solution for me as well,and significantly cheaper than the BCS option,so I may well go with them,having been so pleased with their work so far.

Next little item...suspension woes.

The car has been feeling pretty loose and bouncy,and I finally twigged that the tyres are the likely cause,as the R888s that were on have pretty rigid sidewalls,and the Supersports do not.

So.....down to AMDTuning for a little bit of ramp time to get at the damper adjustments,then we'll see how it feels.

Had a quick trip to AMDTuning yesterday.

Saw the car that Nicolas Hamilton will be driving.....very nice indeed and some lovely work on it.

Got Steve to get the S3 up on the lift and had a good look at all of the damper settings....way too soft.
The front's now been wound up 3 notches,and the rear by 2 notches,leaving the rebound damping set as it was.

Much tighter and sharper now,but probably needs a bit more.

Too soft for track or too soft for 'fast road'?

I'd say both.
The tyres had been changed and it took me a bit of time to twig that the reason it was all over the place was the sidewalls on the Supersports are much softer than the R888s,plus the initial compression settings were too soft in the first place.

I think the R888s just masked that being stiffer,and grippier.

What we did yesterday was just enough to make it more responsive and handle better,but it does need more work when I've got enough time,to get it sorted out,and then to have a baseline setup for both types of tyre.
Steering feels a lot lighter now,and body roll is less,with better turn-in.

The rebound damping seems OK.

Thank you...

I guess what I'm getting at and although one man's comfort is another's loose suspension but let's say compared to stock how comfortable (in terms of stiffness) is your car?

Is it a daily driver or something you can only use as a weekend car?

That's so true.....it's like marmite.

I've had a real boneshaker before(the Escort,which had a rose-jointed fully adustable Proflex-clone setup),and I'd say this car has also got a very hard setup.
It does have some compliance,and rides bumps pretty well,without crashing into everything,but it is overall very hard,and wouldn't be judged as comfortable by most.

It's my daily driver,like all of my quicker cars have been....I honestly enjoy them far too much to simply want them as weekend cars.

Fair enough I think I interpret that as 'it's not comfortable' lmao... I don't know where you live but I'm in West Yorkshire and even with just eibach pro kit springs sometimes our cr4ppy B roads I don't like it lol

If I were prime minister road tax would be ring fenced for roads only. And the M1 would be 6 lanes in each direction with a 3/3 split with express and collector system like Canada. The national speed limit for cars would be 90 mph too.

Sorry to rant on your topic lol. End of rant :)

LOL...where I live the pothole mileage exceeds the road mileage.

OK...it's not what a lot of people would term as comfortable,but I do prefer a much harder suspension than most would to be fair.
I don't want the thing wriggling around much with the sort of performance it has.....my Escort was lighter and ran less power/weight,but was very twitchy around the limits,and I'm not after that again!

There definitely is a line though between stiffer suspension and bad road holding.... i seriously think that the B14s are quite stiff but manageable but if im going on a back road where its uneven surfaces, then i reckon id be slower than on a softer spring set up! The car definitely feels like she may wana skip out a bit if im putting my foot down when there's pot holes and uneven surfaces!
On a flat road or a track, then the B14s would be great round corners and a lot better than softer suspension set ups!

For sure.....if you stiffen things up to the point where the car begins to skip over bumps,then you've gone too far,but also suspension travel and damping play a big part.

The suspension on the Escort was aimed at rallying(from it's past life) and had a good amount of travel but excellent damping,and in this case,the spring rate also has to be factored in.

The Clubsport setup uses linear rate springs,and pretty hard ones at that,so the damping needs to be set high enough to ensure it's not oversprung and underdamped,which it clearly was,as it was bouncing over bumps.
 
I'm stuck with the B14s standard setup lol
At least I know I can't keep fiddling with it or else I'd be always thinking what set up was best and keep thinking about having it changed every 5 mins lol

The trouble with things like these is the range of settings is huge.....and they're "only" 2 way dampers...LOL
 
I've got V3s on mine and they came pre-set at mid settings but I'm polybushed and couldn't live with the harsh ride so I ended up going two clicks from full soft allround.
It's made the drive and comfort much more compliant.

Hi Steve.

Superpro bushes and ALK here as well plus VWR engine mounts.
It all adds up to a fairly hard and non compliant ride plus the Clubsport gear is an order harder than the v3 I had before.

(Spits out teeth and fillings as he types ...)
 
White line don't do an ALK for my model but I would alter the rebound on the front and compression on the rear to slow lift at the front when needed.
I run VF mounts on the engine as I don't want it banging around and the exhaust is pretty tight anyway.

Yeah, fillings do take a kicking but not so much these days now it's on softer settings.
Steve
 
Mines the Superpro ALK.
 
It's not a huge difference,but as a part of doing the whole setup,it does make a difference in tightening things up a little more.

I had the bushes and the ALK installed together,and the whole lot tightened the car up nicely,as well as removing a lot of sloppy feel from the old bushes.

Being the first to use a set of components sometimes means you find potential problems.....

The car did feel a bit slow the other day,and when I got home,I opened the hood and noticed a little bit of smoke coming from the exhaust manifold area.....

Note the wiring to the MAF here....


The plastic trunking was partly melted away,leaving the wiring(thankfully made of tougher stuff) exposed to some pretty nasty heat from around the manifold heat shield.



These are taken after I secured the wires out of the way of hot air rising up from the manifold,which despite being heat wrapped,was seriously hot.

So.....now I need more Zircoflex and some other heat shielding.


Someone a bit more techy will no doubt put me straight on this,but if I'm right,this MAF is a hot wire type,meaning measuring resistance across a heated wire element,and if I'm also baking the leads to the MAF,I can't see it doing anything good for accurate measurements.

Anyway,it now pulls full boost again.
 
So after trying to kill itself,the car has been up to it's old tricks with my credit card again....






This stuff is really pretty good.....safe for up to 260C of direct/radiant heat,but an absolute pig to fit.

It's split lengthways,so you have to open it up,and feed the wire or piping into it,and it then closes up around it,but the nylon inner tubing is so stiff,you need either a tool of some kind to wedge it open,or fingers of steel.

This stuff is also pretty cool(!)....Firesleeve,also good for 260C of direct heat.




So,..before....



And after....





Firesleeve split to allow the N75 wiring to be fitted inside...



And a few left over from it's recent works....

1.The N75's new home...



2.Nice set of port injectors all ready to go...



And an octopus has taken up residence...

Not been on here for a while, it's gonna take me a good while to read through and catch up on what else you've done and how much power you're now running !

What brakes do you have? My pals pal had an S3 running 550bhp and he wants to change the brakes , I'm waiting to hear back from my pal with the Golf R to see if he wants to sell his lambo brakes to him but If not what would you recommend?

Hi,good to see you back.

It's running a daily 550bhp,and was running over 600bhp on Storm's dyno.

It was turned down a bit,as the exhaust(a sort of hybrid Milltek) is running out of flow,and needs to be replaced to safely run full power for extended periods,so that's been booked.

The brakes are again a sort of hybrid,as a lot of the current kits weren't around when I started all this,so it has VWRacing 6 pot calipers,and APRacing rotors on the front,and ZeroSixty rear discs,with Mintex 1155 pads all round.

It's pretty decent,and doens't fade easily,but I did see on another thread that Forge now make a good sized rear brake system for the S3.

There is a way of putting RS6 rear discs on which I think are 335mm. If you're running something like a 360-370mm up front would even the system out stop it squirming around under harsh braking.
