My B5 RS4 - from standard to...??!

Been around a while now and lots of things now going on with the car so thought I'd keep a track of them in one thread

So to recap, I've had a heap of (IMO) tasty motors over the years and a couple of track weapons to boot... but time ticks on, some of the toys and desires have gone by the way side and the refined luxury of an Audi beckoned again!!

To that end I picked up this B5 RS4 back in early December 2010, here are a few snaps of when I first looked it over



Those eagle eyed of you will maybe recognise the registration number as this is one of the original Press Cars registered just before general release and therefore on a W plate. You'll also notice it's pictured outside German Marques as their showroom shares the same build as my office (as does PowerStation) so it was only a matter of time before I had to succumb to the lure of the original (and best) RS4!!



This was as complete impulse purchase though having been more than happy with my current drive (Forester STi) but after 2.5 years there was a little hankering for a change. I'd managed to avoid taking any of the other RS4's out for a test drive that Tom & Aaron have had through their doors but caved in on this one... a test drive later and TBH it was a foregone conclusion that a purchase was on the cards!



It's got a heap of history (looks like everything actually) along with every MoT and had 108k on the clock. The history shows it's been really well looked after and also completely standard, not staying like that for long

Brought over from this thread: http://audisrs.com/about20963.html

Having got my completely standard  B5 RS4 in late December I felt it was well worth heading over to MRC for one of the their Health Checks and Dyno Run to see if all is well before the inevitable modifications start  

Had a fun drive there, was the first time I've really driven the car on anything other than motorway and whilst fast it does feel like a huge heavy boat as standard! There was a small part of me a few days ago wondering if I should just leave it standard but it's such a handful on anything other than Motorway I can see why people modify/improve them!

Anyhow, arrived and was greeted by Dave who whisked my keys away and before I knew it they had started with the health check... sadly wasn't too long before a leak was found which was a split top intake hose on the drivers side (see my WTD thread) which was unrepairable. Usually they split just a little by the valve and it can be trimmed off, mine had split about 30mm down the pipe though so cutting that off would have made it too short. Being the helpful folk MRC are they found a spare so we could at least finish off the check and dyno run.

Everything else so far was fine so onto the dyno it went... Whilst having a nice chat with Doug about this and that Mihnea arrived so he jumped in the car and ran it up.







Results were as follows:

385ps @ 6475
511nm @ 3100




Spot on for power but a little high on torque and that is the result of a spike when it kicks in likely caused by a failing N75 valve (which has just arrived downstairs, so will pop that on later). Very happy with that though  

Along with needing to replace the split hose I have one advisory as the cam timing on one bank is a little over the "guideline" figure and sadly the only fix is to take it all apart and resetting the timing... essentially as much work as changing the cam belt. Also the lamba's are throwing fault codes (have previously cleared the code but comes back) so figure those better get changed too.

24/12/10 - Fitting (Cheap) Aero Wipers

Before shelling out for the proper Aero Wipers and Arm from VAG I figured I'd try out a set of the cheap Aero Wipers from eBay. This is a set specially put together for the B5 with the correct rear wiper length and cost just £10.50 delivered!

Link: http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200523049067

Fitting took a couple of minutes and whilst I haven't tried them yet they look very good indeed























Will see how they go but worth a shot before forking out for quite a bit for oem arms/blades I figure!

21/01/11 - Dyno Run @ PowerStation

Following on from the Health Check & Dyno Run @ MRC on the 13/01/11 I thought it would be fun to run it up on the PowerStation dyno and see how the figures compare







They were really happy about running a German car on the dyno, usually used to Subaru or race cars










Results were as follows:

365bhp @ 6800rpm
322lbft @ 2980rpm




Interesting to compare with the MRC figures and highlights the difference the type of dyno can make to some of the figures

dyno results

Wow that really is quite a difference approx 55lb/ft difference in torque and nearly 20 bhp only a week apart why do you think there was such a significant difference in fugures?

Different dynos mostly. A good example of why you can't really compare one dyno figure with a different dyno figure, though everyone does it anyhow, then argues about the results!!

Given those figures I'd expect to see a similar difference if I ran it again once I've had the first phase of engine mods completed, hell I may even do just that
AndyC

I would suggest different dyno...... we see it all the time..... its impossible to say which is more accurate....

you may as well refer to the power as carrots....
Jonmurgie

Exactly

If you really want to get the debate going, compare the drag figures
AndyC

ZZZZZzzzzzzz not this evening if thats ok..... need to go brush my teeth
pjbRs

This is why it's better to stick with one rr or you will just get confused.

I prefer to judge my cars by how they drive.
AndyC

anyhow we digress, its about Jons car not the dyno differences....


and a very nice Audi at that.... I am slightly jealous .
pjbRs

Yep it is a beauty alright.
JohnnyB

Think 20bhp difference is more than a spot of ambient temperature.
Jonmurgie

JohnnyB wrote:

Not sure where you're seeing 60 difference?!

MRC = 385ps
PowerStation = 365bhp

A theoretical difference of 15bhp but as pointed out, it's completely unfair to compare 2 different dyno figures
JohnnyB

Not slagging your car I put 60 by mistake.

Just would'nt expect 2 RR to be so much different. Not slating either RR either but would expect the figures to be closer.
Jonmurgie

Phew - thought I'd typed my figures wrong

The truth is no 2 dynos are the same so you can't compare figures fairly. Only use of the figures for most people is as a base point before modifications, then using the same dyno will indicate the general level of improvement (excluding any significant shift in the weather etc.)

Other main uses of dynos are mapping and fault finding
JohnnyB

I will be getting a dyno in the next few years when I have done some saving.
Jonmurgie

Well worth it

Funny thought - I had always considered the PS dyno to be a little on the optimistic side... but now I've been to MRC

Of course every dyno owner will confirm it's been calibrated, so...

Anyhow, this isn't to start one of those debates again, just thought it was interesting to add to my thread.

I now know why i more then run against the grimreaper in his 500+ and all that extra Torque .. Or should I say talk

Maha is quite accurate but so the cartec worst I've ever used was dyno dynamics! Don't know what went wrong but 80bhp difference between that and a maha on my mk5 r32 lol
marc1

What's your MAF reading show on vag com Jon? Might as well go best of three
AndyC

My personal favourite is superflow
RoGEK

maybe it all depends on the cooling at the rr..

i see 2 big fans at mrc, what do the others have?
and apart from that.... maybe you got heat soak at the 2nd place you've been.

so much variabeles.......

best is to get an general idea of how much power you have and before and after mapping/modification of the car...

this is not only a discussion on this forum but on every else.

Maybe down to haldex, as my S3 had to be run with the fuse pulled - so 2WD, with 4WD losses.

Also, as Rogek mentions cooling can play a part - the fan setup at MRC is much more suited to cars with SMIC's, rather than a big central fan (couldn't see if that was the case at Powerstation).

Anyway, the other variable to throw in could be a difference in fuel.
AndyC

Agreed

Heat soak can be a problem for out and out power numbers

Power at the end of a mapping session is usually less than after a cup of tea with the fan running to let it all cool a little

on the other side of that a warm transmission with warm tires etc will have less loss and therefore (on SOME dynos) give more power

Id like to see more cars dyno'd on independent rollers to really see the differences from 1 to the next

I do think vbox is a better messure of real performance.

Apart from all the Dyno talk LOL
I think thats a great, interesting write up on your RS4.

28/01/11 - Fitting B7 RS4 Wheels

Following on from collecting a set of B7 RS4 wheels last week (see here http://www.audisrs.com/about21279.html) I finally managed to get the car on a ramp to try them out.
























Parked up outside German Marques to show Tom and took a couple of snaps, their Avus was parked outside too





I'm not 100% convinced about the colour yet but it's growing on me. The wheels, they are exactly what I wanted and I love them for that... I will probably photoshop my car a little and see if a few other things going black will work better.

The wife spotted the wheels today and said I've ruined the car... typical woman  though it has changed the look of the car massively IMO and it looks a little 'gangsta' so again I'm not totally sold on the colour yet!

07/02/11 - Fitting Big (Gear) Knob

Got around to fitting the Forge Big Gear Knob the other day... I won't go into how I removed the standard knob but I'm quite surprised at how much I like the Forge one as it's MASSIVE but very comfy and easy to change

Looking forward to when the JHM Short Shift arrives too

04/03/11 - Fitting OEM Aero Wipers

OK, so the cheapo aero wipers suck really, they are what they are which is cheap and cheerful. They just don't look quire right so the plan was always to go for the proper OEM Aero Wipers that you can get from the later spec B5/B6 chassis.

Not a cheap mod for wipers the first time out, but that due to having to buy the wiper arms, blades are no more pricy than any other when it comes to replacement time so no longterm costs really.

Fitting is super easy, though the way the arms tuck under the bonnet it's a bit of a bonnet up, down, up, down affair. Took some pics along the way...

So the wipers and part numbers first






As a reminder, the cheap aero wipers






So to remove the old arms, lift the cap to reveal the nut






Then it's the fiddly bit with the bonnet as it's kind of in the way. Just take it easy here and do it slowly




Comparing the old and new arms




Now another fiddly bit, get the new arm on the spindle first.




Lower the bonnet then position the arm into the position you want it to be at rest.


Lift the bonnet and refit the nut and cap. Worth noting that you don't get as much thread exposed with the new arms, but more than enough for it to be fine.








Now it's just a case of fitting the blade. They have a really easy method of fitting, by far the easiest wiper I've ever fitted over the years. Just a case of turning the blade upside-down, sliding it on the pin and spinning it over. Done!








Here's a comparison with the cheap aero wiper on the passenger side


Repeat on the other side and enjoy a much more modern look, less clutter from looking out through the windscreen and very very good wipers









Love it
Jonmurgie

Interim update - been waiting for a set of the Whispbars to arrive from a supplier for an impending holiday. Arrived yesterday and popped them on, fit great and pics of the bars to follow but tonight I grabbed my mates roofbox and gave it a quick run





Excuse pics, they are iPhone snaps... with the bars I also bought some mounts that take advantage of the T section of the bars so the box is held on directly to the centre channel of the bars and you don't have to have those horrible U clamps on the outside.

Looks great, nice and low profile



Tested on the way home - all good up to a 'decent' speed
ddidds

very good choice going for silver b7 wheels ! looks much much better !
RS4Jules

This car is really coming on a treat.
The wipers and B7 wheels were 2 of my first mods when i first got mine †


P.s get them horrible halfords stickers of the roof box lol
Jonmurgie

Yep, coming along nicely now - got a few things to update on this thread when I get the chance but popped the silver B7 wheels on last week and much MUCH nicer

Finished off the AST setup and with the Neuspeed ARB fitted it handles sooooooooooooo damn well for a bit heavy estate!
marc1

Looking good Jon - all ready for a road trip then?  Fancy sending the black wheels to me so I can have them resprayed Titan and put on my car? PM me with a price and details if you like.

Much better colors of wheels.
I bought aero wippers for SKODA Octavia, it is kit, and you dont need to change hands. Just wippers.

OMG yes mate - it's by far a bigger change to the handling than the AST's I reckon! I had the mis-forture of driving the car for a couple of days with NO ARB at all as I'd pulled the old one off but ran out of time to fit the Neuspeed, hideous as you can expect! Fitted up the new one, which with the support brackets is no mean feat (nothing seemed to line up!) but once done it was amazing, simply amazing. I also fitted the RS2 drop links so not sure if that also had a part to play in the transformation...

For the money, I'd say it's the single best modification to the RS4 suspension by a country mile.

Gonna do a small write up shortly...

You never changed yours did you?

Rasss-4 wrote:

Lens, not too much camber to be honest. Forgot to get a print out from the alignment the other day. Gotta go back on the machine as the steering wheel is off centre so will get figures then. Sadly, as we know, you can only adjust toe on these without going for the adjustable arms etc.

marc1 wrote:

The rear springs were swapped to the setup used in the GB and all RS4/S4 kits. Originally it had a single spring which wouldn't quite go low enough so it was changed for a shorter spring and a helper spring to ensure everything stays in place when jacked up. Much better
sonny

Agree ride height looks spot on. Love the "above" pics of the car.
Rasss-4

No Arb???  ha shit bet that was some fun hey!!!
The ride height does look very good, looks well planted and the silver B7's look bang on with the Avus too  

I did originally get the neuspeed but after having it wks in the cupboard I only checked it properly weekend before the AST's were to be going on and it turned out I got sent out the 21mm instead of the 19mm    so I was wounded when I was told that I would have to wait up to 3wks for the exchange so had to get a F&R hotchkis set off Grizz within them few days before curtis was going to fit my AST's.
Ended up having the ARBs fitted by MRC whilst getting my service, drove it for couple wks before having the billys fitted so I never got a chance to do it vice versa hence my question to you about Before and after!

08/06/11 - Fitting Neuspeed Rear ARB

Having read up on several threads relating to uprating the ARB's on the RS4 I felt the right upgrade was with the Neuspeed 19mm rear only (inc. brackets) and to leave the front ARB standard. This does seem to divide opinion but the logic to me is that leaving the front standard and thickening up the rear will have a more dramatic effect on the overall handling over thickening both the front and the rear.

Well, that's what I feel so that's what I did

I also took the chance to replace the plastic OEM drop links to the metal RS2 drop links, from this thread I went the Lemforder links which cost £64 delivered for the pair.

The 19mm Neuspeed ARB came from Awesome GTi who are the UK Neuspeed dealers and it cost pretty much £208 + delivery: http://www.awesome-gti.co.uk/product.php?xProd=8043&xSec=410

Fitting was pretty straight forward with the exception of the reinforcement brackets which were, quite frankly, a PITA to fit! I'm glad I had the use of a proper car ramp and also a hydraulic stand that I used to push the bracket up so the bolts would go through.

Here are some pictures of the install... firstly the ARB kit along with the new drop links, all really nice stuff and very well made:







Standard ARB is super skinny, think it's 15mm. Removing it was a doodle as were the plastic drop links. before you say anything, I know the exhaust bracket is broken, just awaiting the arrival of the Milltek system







A quick comparison of the old and new ARB:





So first it's on with the drop links, the natural thing to do here is fit them with the bend in the same place as the plastic ones yeah? Well turns out it's not as with the new ARB the bend touches the drove shaft. No biggie, but just a note that the drop links need swapping sides to fit correctly. Didn't spot this until almost the end so some pics show the drop links the wrong way round!





Then it's onto the reinforcing brackets, a great idea and love how they utilise some OEM holes so no extra drilling required. Fitting them, however, is a tad fiddly and a "tips of your fingers" job to get the washers and nuts onto the bolts in places. Also, don't be alarmed if things don't line up that well, looking at the subframe where the ARB is fitted you can see WHY you need a bit of extra bracing as it's essentially a single skin of metal with no box section of any kind so is practically free to flex as much as it likes. This "may" be a reason for the brackets not lining up at all but I've heard similar stories of things not lining up.





Next the ARB get loosely attached to the drop links (note drop links still wrong way around!)





Looking good so far



Now the next tricky part, lining the holes up! As said above, things are a long way from being lined up so I used a hydraulic stand to push the bracket up into position. It took a fair about of lifting and it would be a huge PITA to do this on axle stands rather than a proper ramp that's for sure. But it did the job †and sure enough everything slotted into place.







Repeat on the other side, then tighten everything up (until now things had only been "nipped up"), then job done!







Couple of shots showing the bottom of the brackets do sit a little low, not caught them on anything but worth noting I though





And the results - WOW † †absolutely stunning transformation! I've had the AST's on since mid Feb so quite used to them but this updated ARB has shifted the handling onto a whole new level. The car just stays so flat though the corners now. Finally it feels like a light(er) nimble(ish) thing, it's never going to be a CaterField but for what it did handle like it's a huge huge huge improvement :thumbup:

So that's it, suspension mods done for the time being. There are loose plans for the fully adjustable arms from 034 at some point but no rush really.

Can't recommend uprating your rear ARB enough people - it's a cheap upgrade and you will be amazed at what a difference it makes
Jonmurgie

Little update - following a "swap" post on the forum by dogmatic (http://audisrs.com/about26477.html) I met up with him over at Nick Johnsons to swap my black set of B7's for a set of MTM's which are polished with anthracite inlays.

Whilst I love the B7's the style of wheel are soooooo common on VAG's  so fancied trying something that looked a little more OEM (same spoke pattern) but bigger.







I think they're going to look pretty good on the car TBH, the anthracite inlay suits the Avus quite well!

Got to sort some 265/30/19 tyres out for them though (selling the 255/35/19's here http://audisrs.com/about26519.html) but you gotta love getting 8 x 19" rims, 2 of them with tyres, in the back of an RS4! So much room





Nice to meet Nick Johnson as well, a really nice chap and I can see why he's so popular with people looking for super tidy RS's

In other news, I've moved offices so no longer above PowerStation... it's a nicer office though

It will look bang on with the Stance you got Murgy.
I did wonder where the wheels went when I only seen the tyres up for grabs!

Ive never been a massive Fan of B7's on the RS hence why I sold mine to you BUT looking at yours, I think they are perfect for the Low Avus...

Am running 10mm all round at present (B7's are ET29) and will need them for the MTM's as they are ET30. Will get a set of 15mm and see how they look actually, the MTM's are slightly wider than the B7's so may need those few extra mm.

Wheel whore - kinda but really just looking for the right look
Jonmurgie

Just noticed as well that they are 9.5" x 19" so that's wider than the B7's so maybe 275/30 would sit better on them?!
Rasss-4

Yeah 9.5J's the 275 will sit better.
So you should be ok with the 10mm spacers then with that little extra width from your Alloy.
Nothing wrong with being a Whore Jon - we're all guilty of it  

I reckon with them MTM's and a 275 tyre mounted with the 10mm spacers will do the trick.  

Them wide alloys make the RS look so much beefier from behind, especially with the spacers, I reckon your onto a winner there murgatron

Bloody hell Jon, I can't keep up with your wheel updates.  I may well have missed this thread!  The MTM's do look a bit special though.  Oh and you know what else I might say, so PM me

Ta, used that last time, but right hand strap is tight against bumper so not ideal:

Much stiffer than OEM but not noticed any 3 wheel action over dips/driveways etc. Mines set on the softer of the 2 holes (so nearer the ends). I guess you're getting it lift on 3 wheels then?

14/07/11 - Scorpion CAT-Back Exhaust

Whilst deciding/waiting on the final system for my car I had the opportunity to go for a Scorpion CAT-Back so figured why not! No pictures of the install as it was done by my local VAG specialist (having now moved from above PowerStation and daily access to ramps!) but here are some before/after shots and a movie too

And the verdict - it's surprisingly loud! Not what I was expecting at all TBH, and driving it back from having it fitted I was all set on having it taking straight back off again! Well my old exhaust was well shot so that wasn't an option as it happend, but I'm pleased to say it's got a fair bit quieter and I'm getting used to it... must be getting old though, loud exhausts used to be ace!

Scorpion won't be on there for much longer though, I think my new system is almost ready

Plan was then to run the car up on the Dyno @ PowerStation, which I did - however things aren't right as power was way down on the car from the run in January so figure there must be a boost leak somewhere (yet to check VAGCOM and do a boost check). Shame really.

Anyhow, Dyno video with the Scorpion CAT-Back exhaust (and a modified Air Box) is here:

Well thanks for the comments

Moving on, my PODI gauge arrived today so that's yet another job to get done sometime!





Came with a silver bezel fitted but I'll be using the supplied black bezel I reckon

Oooh that podi looks lovely

Another update - this one is in 2 parts, the first of which was done a little while ago, then updated recently!

10/07/11 - Airbox Mod
more details @ http://www.mdracing.co.uk/gallery_rs4_airbox_mod.asp

Having read up and asked a few questions about the "airbox mod" I picked up a s/hand RS4 airbox (which is different to the S4 airbox) to hack about with. I've seen several different versions of the mod, from practically cutting the entier bottom off the box to actually adding a second actuator to the box.

I ended up going for cutting out the front facing section of the airbox and even with the standard airfilter you can hear a little induction noise and a faint sound from the DV's.











I did drop in an ITG panel filter, though it was the wrong size (B7 fitment supplied in the B5 box!) but by the time a replacement had arrived I had already sorted out the bits of an induction kit as below, so that's still sealed in the box!


21/08/11 - K&N Induction Kit
more details @ http://www.mdracing.co.uk/gallery_rs4_kn_induction.asp

Whilst messing about the airbox mod above I remebered I had a sealed K&N Filter in my garage from when I had my Evo 5 (supplied by Forge but never fitted). I dug that out and set about getting the other bits to make up an induction kit.

Essentially the kit is made up of the following:

89mm 45deg bend - link
89-76mm reducer - link
Alloy Trumpet - link

I had already fitted an 89mm hose in place of the OEM accordion hose, which requires cutting when used with the OEM airbox. With the induction kit there is no need to cut the hose so I have since fitted a new uncut hose which moves the filter a little further away from the engine.

Anyhow, here are a few pictures of the install, with a cut MAF hose...









So what does it sound like? WOW, the noise it makes is insane! I fitted it on the dyno the week before last so my first taste of the noise was flat out to red line - though I was going to be sucked in!!

Here's a video of that dyno run so you can hear it, made a 10bhp increase over the previous run with the modded airbox (runs were back to back with filter change in-between)

Now when you have a setup like this you loose the mounting point for the Ignition Amplifiers, which is on top of the OEM airbox. As I was unprepared for this I simply cable tied them out of the way to start with but knew a solution would have to be sorted out.

Today, amongst other things of which will follow, I set about fabricating a heat sink plate to mount the Ignition Amplifiers too. Using a 4mm piece of aluminium I've fabricated a new heatsink that utilises a mounting point of the OEM airbox and keeps all the wiring neat against the engine bay. Works really well and should be enough to keep the amplifiers from over heating.







I also swapped the MAF hose over to an un-cut 45deg pipe and you can see the filter is now as far forward as it can go. Here is the induction setup as it stands:



A nice solution I think

Next job is to fabricate a heat shield...

I'm not keen on the size of the pipe on the K&N ... smaller than the MAF

Thanks Mark,

I'm on the look out for a larger trumpet but that's all I could get at short notice and cheap.

Made a significant increase over OEM airbox so can't actually be "that" bad

Fair enough

Just found one with a 100mm outlet but it's £57! - link




And another, £80 this time! - link
