Cuppa's S5 Coupe (Supercharged / Meteor Grey)

Hi all, thought I'd post up my car build to date.  Haven't included everything, just things I have pictures of.  This is a comparison shot of now vs when I collected it...



Been an Audi driver since 1998 and had a workhorse A4 1.8 from new until last September when at 140,000 miles with lots of outstanding repairs it had to go.

After much debating I bought a 2008 S5 Coupe in Meteor Grey with Magma Red interior.  I've had her a while, not that many factory options, and a few simple mods so far, but the real work starts now the warranty has gone.

Was a big step up from a 1.8 to a 4.2.  By March/April time this year I was getting fed up with the stock stereo setup so decided to do something about it...

3 Sinfoni amps...


To drive Morel Elate Limited Edition speakers in the doors...




And some added bass


Sound was great, but it got me hooked on modding...

1) "How can I make it go faster!"
I did some research on the V8 engine and saw mapping did diddly squat, so thought supercharger.  Did my research on various kits and went to spend some time at TTS to see their Rotrex kit and be driven round in their car.  I was sold.  They pointed me towards MRC Tuning for the fit.

Dyno'd at 328ps, down on stock.  Carbon cleaned due to


Supercharger fitted...




Before and after figures on the same graph.  A healthy increase to just over 600ps


The install came with Milltek downpipes and Milltek catback exhaust.  Sound was loud on the outside and turned heads a plenty, but the drone inside the car was unbearable for me.  The exhaust eventually had to go.  More on that later.

The Supercharger itself is glorious.  It has transformed the car - initially it was scary (remember 6 months before I was pottering around in a 1.8 ).  I also had a JHM Short throw shifter fitted which I really like.  So much so my next thoughts were...

2) "I need better brakes!"

So.  Wanted a stock OEM look to it.  I was offered some RS6 C6 brakes and the RS5 BBK, but I managed to source some of these from overseas at a great price...



Brake kit came with calipers, pads, discs, guard, etc., but once fitted it was obvious it needed the RS5 brake servo also to work properly.

Whilst I was at it I had the rims and tyres changed for 20" and had a H&R sway bar kit fitted


And had the exhaust swapped back to stock downpipes and the Capristo Valved Exhaust



The sound now is PERFECT.  Sounds great from outside and nearly silent inside (which is just what I want as I love my music).  The valves open due to backpressure (which can be customised) so this works perfectly with my charger.


3) Handling and a drop
I'd been advised to sort out handling a while ago but wanted everything else sorted out first.  Initially didn't want to drop the car either, but thought a slight drop would look good.  I had a dilemma.  How could I have a comfortable car which is my daily driver and I do about 300 miles a week, plus have it setup for the track, which is something I had been considering getting into.  Could I have both?  I'd been reading about these KW DDC 'iPhone' coilovers which KW had recently released.  A button in the car to switch between comfort, sport and sport+.  You could also control the damping from an iPhone app in 1% increments for each axle.  I noticed on their website they had them for the S5.  Jabbasport in Crowland sourced them and fitted them for me.





These are great.  Based on the KW V3 coilovers, but with an immediate change to suspension through a button.


And now the aesthetics.  These have happened along the way and perhaps too many to mention, I'll let the photos do the talking...




Got this off ebay.de



So this is how it looked at Audi Driver International.




A few pics of the completed spoiler install...







Next came the Rieger bumper.







Then the Rieger Luftseiden side skirts...









Next came the S7 Rear ceramics...





and the SPC adjustable upper control arms...



And that's all for now.  More to come.

LOL, only registered today.

Ceramics are great (apart from very first braking on cold mornings).

And do you still have the S5 grill and/or sideskirts for sale?
Nez

Wow car looks great....
Cuppa

Still got the sideskirts somewhere, but the grill went a while ago.

very nice looking car bud, pretty trick suspension too!
Cuppa

Suspension is neat, I don't have an iThing so just waiting on the Android version of the KW DDC app and I'll be able to play with the settings a bit more.
Marc R

Very nice project!   I bet you doubled the price of the car along the way.
dr.sah

Bravo. Very nice car. I love all. Except the music.
Olly P

Good write up, awesome car!
ToddS4

Wow, serious cash being spent, great setup tho with all angles covered

Love it and I bet the noise is intimidating too!
There is some cracking motors arriving here lately  
Cuppa

Thanks. Turns a head or two with the exhaust valves open.
colin123

Lovely looking car...

Great write up bud!  Car looks stunning, love the S5 shape, and the interior looks soooo coooool!

Chuckled at the fact that you got the suspension but don't have an iPhone!  Good on ya
IainRS

Great write up. Lots of really nice useful mods there. It's very easy to spend a fortune once you get into this modding lark.
coullstar

Never been an A5 fan but I like this.

Anymore info on the Capristo valve.
Cuppa

Thanks

Yeah, funny really, thankfully others in the house have them - I just don't reallly like iTunes.  KW dragging their heels on the Android version which is a PITA

What do you want to know?  Capristo is a cat-back exhaust with back-pressure sensitive valves.  Normal running the valves are shut so only 2 of the quad pipes are open (through the silencer).  When the backpressure increases to a certain limit then the vales open the other two pipes (which are straight through).  The settings for backpressure are Comfort, Sport and Open, i.e. Comfort mode the pressure threshold is higher, sport it's lower and open - well they just stay open.  You can customise the pressure thresholds for comfort and sport so it's perfect for a charged system.  Get 2 remote controls with it.

It is.  How you finding the TTS charger?  Did you go up to TTS to have a look around?  Richard's a really nice guy...

Cuppa

coullstar wrote:

Some videos of the Capristo.  I was testing out the manual spoiler button to check it worked (was when I retrofitted the RS bootlid), but it's the best sound clips I have of the exhaust too.  One is of the cold startup and one is from slowish to 60mph and then lifting the spoiler a couple of times.  Will get some better clips when the weather gets better - need to get a better windshield on the mic though.

Sound is a little quiet so you may need to turn the sound up.

I'm loving it! I had a PES supercharger on my car previously which was quite a different beast,- but still LOTS of fun. I was quite happy with the new level of performance from the 531ps and 611nm the PES produced but after speaking to Danny(S4player) who had both PES then TTS on his car I just had to go TTS next! The TTS charger is a pretty special piece of kit that elevates the performance of our cars to that of a 'supercar,' but it is still far too expensive I think. It has ran faultlessly since fitting, only negative comment I could make would be that very occasionally it seems to 'choke' on full throttle. Maybe just my driving? Have you had any issues at all with yours?

No unfortunately I didn't get to TTS/meet Richard, its a bit far to go. I just shipped my car down direct to MRC.

I had a cold start issue when first fitted which Doug soon cleared up (lambda probe related) and since then has been a dream.  The level of performance is astounding - I guess you get what you pay for.  The way it pulls as you hit 7000 rpm is crazy!

I want those brakes!
Glen_S4

Awsome Car... Given me a few Ideas, Like the Exhaust. Im the same as you, quite like the silence of the Sound inside, but still want a decent note outside.

Looking to visit MRC myself soon.

Coilovers are Sweet aswell.

Back up on the ramp today.  Wanted to do something different with my brake calipers.  I love the Audi ceramics, but the grey caliper colour is a little boring.  Bright red is a no-no, but I really liked the R8 GT Calipers.



So, out with the old...



and in with the new.  The R8 GT Calipers are a direct swap:



Cuppa

Rear calipers have been blasted to remove the paint...



Had the front filled in with a blanking piece welded into place...



And just smoothed off...

colicabcadam

LOL - you'll never be able to leave it alone !!!!!

nice touch on the rear brakes, a different approach !!
Cuppa

The rear brakes need to be smooth ready for the next step of painting to match the colour of the fronts.
colicabcadam

it still amazes me though that audi still have not sorted out a proper rear caliper setup !!!

keep us updated, any videos ? aceelration / dyno ? all interesting !!
Cuppa

Once the weather gets better I'll take some videos.  I will be attending some meets this year though, Audis in the Park, Stanford Hall, etc.

No videos on the dyno, just the dyno chart in my first post.

These rear brakes have certainly made the braking more balanced, the nose doesn't dip as it did before under hard braking.
RS4Jules

Wow man this is amazing,like already said i want your brakes lol.

Keep up the great work

I really like that, fair play to you
Cuppa

Cheers.  Sun came out today - you can see the caliper colours a little better...





Got the stance exactly as I want it now.  5mm front spacers fitted.



Just as an aside, somehow got 24.3 UK mpg (20.2 US mpg) out of my last tank.
colicabcadam

what a car, loose the camp valves though lol
Fuzzy Dunlop

The only thing I would change is the badging on the wing. I'd remove it and keep it stealthy.

It's a stunning car though!
Cuppa

Been thinking about taking those badges off for a while.

Rear caliper decals or leave plain?  What do you reckon?
reaper

Nice work, cars looking great

Lovin the brakes and only hope my ceramic set-up looks as good when I install em!
Graham

What a great spec car.

I never thought I would say it about any Rieger product, but I like that front bumper too.

So you actually swapped the front ceramic calipers to the R8 GT cermaic calipers just for the colour change?    Is there any other difference?
Cuppa

No other difference, just swapped for the colour change.  I have the others ready to move on.

The Rieger bumper is a bit hit and miss, all down to the fitting and painting - there's been a few mini-disasters I've seen with it - need help from someone who knows what they're doing.
mckay9

Like your style, you have impeccable taste sir!
Cuppa

Car went in for a wrap today and some rear caliper decals.

3M 1080 Brushed Titanium...


BTW, here's what all the brushed metal finishes look like. For those who like the murdered out look the brushed black looks beautiful. The blue would look knockout too.



Caliper decals are cut


Wrap in progress


Wrapping finished. The valance in silver was too bright for me. This titanium is more subtle.





Rear calipers now complete






Have to say a big thank you to The Sign Team for wrapping the front valance and cutting the decals, plus a big thank you to Luke @ Jabbasport for all his hard work getting the rear brake calipers to this finished result.
TMBirjoo

Cuppa...............You're The Effin Man!!!

Decals on Rear Calipers make them look much better.

Front splitter looks smart aswell mate

When i 1st read about it going in for a wrap, i thought the whole car haha

Simply stunning, lovely car!!!!

I would have fitted then decals then laquered over the top being picky

LOL, that's exactly what happened.  The original brakes were left just as basecoat until yesterday.  Then cleaned, decals applied and lacquer put on.  Then sanded back a little with 3000 grit to matte them off a little to try to match the fronts.

Superb!

Moved to 'Projects & Builds' forum
DW

I think it's almost as good looking as my B5  

Seriously though it's one smart looking piece of kit you have there, well done that man.

IMO this illustrates how too conservative Audi are with their styling, particularly with the A5 and variants. You have made it what it should be.

It looks like it's doing 200mph when it's parked up

Agree 100%  

I like to stick to Audi OEM parts, just use them from other models.

A few updates

Stripped out the old Concert head unit and had it rewired and the Google NAV MMI 3G+ put in (bringing with it the MOST fibre network).  Added an Audison DA1 to extract the digital audio from the MOST network and an Audison Bit One DSP, replaced the rear speakers and amp to match the fronts and added some other bits and pieces (rear parking camera, etc.).  Also debadged the sides of the car and put a flat bottomed steering wheel on (required a bit of harness rewire).

Some pics below...

Doesn't get much more bare than this






Some of the stuff going in




When the Google Maps fired up - didn't manage to keep the camera steady when rushing to take the photo of the initialisation screen and just missed it.



New RS Control panel (with the S6 start button transferred and the stupid coin slot blanked off and the KW DDC button mounted there).


Nav Unit


Rear left boot cubby hole.  In here we have right at the back an OEM amp to drive a single centre speaker to push out system sounds (parking, telephone, etc. when the ignition is not on).  Then two of the three amps behind the MDF panel to drive the Entertainment Audio, then the Bit One and the DA1 mounted on the panel, along with the Audi DAB Radio unit.  The third entertainment amp is mounted in the spare wheel area.


Bit One remote control (to control master volume, sub and DSP settings) is under my centre armrest.  Once setup though you don't actually need it, the tone balance and volume inputs are all passed through from the head unit.


Nice to have an updated screen and finally be able to see album art
LeeT

I love that satnav. Couldn't really justify it in the A5 though. Just bought a set of those 20" rotors though which i am now thinking will look good on my B5
Graham

Some serious retro fitting and modding going on there, I am impressed.
Glen_S4

Very Impressive and very brave to be stripping the interior bare.
Cuppa

If anyone is at the VW Stanford Hall show today I'll be there on the A5OC stand. Come and say hello.
Cuppa

So whilst I've been happy with the looks of my car from the front and side, one thing has always irritated me - the rather crappy S5 rear valance - a boring lump of grey plastic.  I ordered a duplicate to try to customise, but soon succumbed to the inevitable. There is only one rear valance I truly like and that is the one on the RS5.  I knew this could be done after seeing a project by rudiyoda, but it would mean surgery to my Capristo which had always put me off, but after consulting Luke @ Jabbasport he was convinced he could sort that out.

So, after taking inspiration from rudiyoda's excellent thread and sourcing the parts from llBen it was rear valance time and some surgery!  This is a rather long post and rather picture heavy!

I collected the bumper from Ben and took the undertray section to be wrapped to match the front.







I really do like this brushed metal wrap.  Whilst out I took the car over to Jabbasport to have the back boxes taken off so the bumper could be fitted.  Once that was done I took the car over to Martin Bradley to start the process.  First we had to get the old bumper off which was surprisingly easy...



Popped the lights out...





To make the new bumper fit there was some refinement required, some packing of some areas, trimming and removal of others, but the main thing was the need for new brackets...



Then the new bumper was put on - like I said, some packing pieces were required to bring the panels flush, but nothing major.  The bumper once on showed the difference which needed to be addressed with the use of a special tool which was like a piston with a hand pump - this was placed between wheel arch and main body to force the wheel arch out...



Once the arch was lined up it was a case of filling and profiling...







Bit of work to adjust the lug holes and put packing pieces in...



Once lined up, then fill and sand until lined up...







Once everything was lined up it was time to start preparing for painting...

















Then the painting began.  I mixed up the paint - this is what makes Meteor Grey...



and then let Martin get on with what he does best...





Then brought her out into the sunshine...



Refitted the rear lights...



Cuppa

And finally put the rear valance and chrome exhaust rims on...











Part 1 was complete.  Now just needed to get the Capristo back boxes modified and back on.  Over to Jabbasport.  Below are the backboxes prior to modification...



Luke had to adjust the angle, protrusion length and placement of both the brackets and valves.   By the end of the day the backboxes were modified and fitted...







Huge thanks to Luke @ Jabbasport (again) and Martin Bradley.
Cuppa

Then took her out for some photos...

Whilst the last of the major bodywork mods is done, been working on finishing off some of the other mods which have been a work in progress.  Last week the front parking sensors were fitted to the bumper and hooked up to the wiring which had been laid previously.  The reversing camera has also been enabled with the addition of the new parking module.  Some pics of installing the front parking sensors...

Had to position them as they would have been positioned on the Rieger PDC bumper.  Luckily I kept the front PDC mounts from the RS5 grille as had been tempted to sell them on.



Wiring up the back of the Rieger bumper...





Still getting used to the front beeps and also the display and camera - a bit freaky to start with.

Also installed a capacitor in the boot to help with smooth power delivery for the audio DSP and amps.

Great upgrade, car is looking very good

Capped the red valves with a Titanium spinning cap to tone down the red a little.

Bit of a makeover, Meteor Grey now in Matte.



Graham

Looking good. I think that could be the first car I have seen in a matt finish that I have liked. It has really highlighted the great lines of the car.

Thanks Graham.  I was so apprehensive about doing it, but so pleased now with the finish from the transparent matte film.  I so didn't want to part with the Meteor Grey as I didn't like the greys you usually get on wraps, but I love this as I get to keep the colour and change it up with the finish.

Happy to admit that I think I've made a mistake in the front lip colour though, swapped for 3M brushed alluminium and think I should revert back to the 3M brushed titanium plus get the door mirrors caps in brushed titanium to match.

Need a bit of sunlight now to see if the Meteor Grey still goes blue/purpleish through the wrap.

I have just read the whole build and it's a great credit to you on the meticulous way that it's been thought out and executed.

Classy and purposeful as well as bad ass gorgeous


Well done that man for thinking outside the box
