Boostib kuskil 0,5-0,7Bar... selline tavaline on 0,55-0,6bar ja boostib päris madalalt juba ja hoiab kenasti kuskile 5500rpm'ini, siis hakkab
langema. No mina seda chippinud ei ole ja mitte ükski asi ei viita sellele, et oleks chipitud. Samuti kiiruse piirik on 250km/h... testitud 
|
Boosti järgi on jah täitsa stock soft. Imelik. Kas sul on ülemised katid ka minema visatud?
Peab vist ikka ise ka dünos ära käima.

Mul kõik katid ja pütid minema visatud, viimase püti lõikasin ka lahti ja tegin seest tühjaks - tulemuseks oli viimase puhul vaid see, et vaiksemaks
läks ja paukumine kadus ära

S4 Tuning / S4 Buying Guide
This tuning guide is based on the B5 S4 with the 2.7litre twin turbo motor. These cars can be now picked up for between 3 to approx 8000GBP, which,
given the fact that its engine is based on the humongously more expensive RS4, makes the S4 a bit of a bargain. The S4's 2.7litre turbo can be tuned
to over 500bhp on standard engine internals making it possibly one of the cheapest 500bhp cars you can buy. Here's how to get an S4 to the magic
500bhp mark.
S4 Tuning - Brakes
The standard S4 brakes could be better. They fade after just one big stop. This can be largely sorted with the use of some high quality performance
brake pads. If this still isn't enough for you the next step is to increase the diameter of the brake discs. There are a number of ways of doing this
and all methods require upgrading the wheels from 17s to 18s. HiSpec make a kit for 1500quid and this should be up to the most extreme track use.
There is also an option of fitting the B7 RS4 brakes which use 8pot Brembo calipers. Speak to MRC for more details.
For the rear brakes a easy option is to get S8 caliper brackets which gives the ability to fit S8 discs. Calipers are extremely long lasting with the
only really problem coming from the ABS electronics. The ABS circuit board can be reconditioned for a few hundred quid but if you want to replace the
complete module this will set you back about a grand.
S4 Tuning - Suspension
S4s with over 60-70 thousand miles ask if the front suspension arms have been replaced. There are 8 in total, 4 each side and when the ball joints
wear out you have to buy a complete arm. The full set will cost around 600GBP. Any rattling over bumps is most likely the anti roll bar links which
are much cheaper. Springs and dampers can last for a 150000miles.
One of the most cost effective improvements that can be made is H&R anti roll bars. The ride comfort stays the same but the car corners flatter
and they give the S4 a more neutral balance.
For track days a coil over kit is the way to go, Bilstein and H&R both make a kit for the S4.
S4 Tuning - Engine
The 2.7l V6 Twin Turbo motor comes with 265bhp as standard. To get over 300bhp a simple remap to up the boost from 0.5-0.7 to 0.9-1.2bar, MRC can do
this for you for 400GBP. Combine the remap with a performance exhaust system and larger, second-hand RS4 intercoolers and the motor will be making
around 330bhp. The pre cats can be removed and the car will still pass the MOT. Milltek, Supersprint and Scorpion make exhausts for the S4.
340bhp is about the limit of the standard K03 blowers. The next step up the turbo ladder is the K04 turbo. They are nearly the same price as the K03
turbos so its a no brainer upgrade. The K04 can supply enough air for 370bhp with a remap and the standard injectors and fuel pump. Uprated the fuel
pump to a Bosch motorsport item and the injectors to 440cc capacity squirters and your looking at 450bhp with a suitable remap.
For the magic 500bhp 600cc injectors are required, hybrid K04s, tubular or ported original manifolds, thicker head gasket and a 3inch bore exhaust.
The RS4 has uprated internals over the S4 but it is believed the S4 internals are hugely over engineered anyway, the RS4 internals are overkill.
The exhaust manifolds have push fit pipes inside them which can come loose and rattle. Manifolds are not expensive due to many owners upgrading to
tubular items, its the labour that costs here, 950GBP of it. Its a good opportunity to upgrade the turbo and change the cambelts while your doing the
manifolds.
S4 Tuning - Transmission
Civil engineering more than automotive engineering went on in this area. The standard box is good for 650bhp just change the oil every 100k or 3 years
to keep it fresh. If there is any area that can be found wanting its the clutch. 370bhp is the standard clutch's limit. Fortunately the RS4 clutch is
a straight swap and this can hold 500bhp with no problems. The clutch can be changed when your changing the turbos.

Uurisin MTM'i lehte, kus max jõuga paketi kohta annab umbes sama numbri. Ja ma saan aru, et soft on sama nii ~220kW kui selle ~250kW puhul. Seega kui
mul on kodukootud kativaba vl ja 232kW soft, siis võib vabalt olla seal ka 250kW? Või peaks väljalaskes midagi veel tegema? Teiseks, mida minuarust
pole biturbo teemas veel räägitud, on " modification of air filter housing". Mida, kuidas täpsemalt, on keegi teinud, on mingit efekti?

Dahlback Racing reports it hits over 295whp from the stock K03s when using its 3" downpipes with 100-cell cats, specific software and RS4
intercoolers. The kit retails for $3495 and includes all hardware, but you'll need a cat-back as well. Keep in mind you'll also probably
need a new clutch, which Dahlback has for $2100, including disc, pressure plate and single steel flywheel.

WHP stands for wheel horsepower. The factory rating does not include the losss of power throught the transmission or the differential but this
does. It is what you get when you put your car on a chasis dyno. It is what your car is atually putting to the road.

stock DPOs will always struggle to get more than 400- 430 ish
Mikse
Summa summarum:
If you have S4 engine you are limited to 530hp no matter how big turbos you go. The biggest (and the best option) turbo you should go
is RS6.
With that you´ll need:
- better intake
- whole fuel system
- bigger exhaust, DPs and catback
- bigger ICs
You Don´t need:
- bigger inlet pipes
- bigger bipipes
- exhaust manifolds
- intake manifold
- meth
All parts above has been proven to flow more than S4 heads/cams
I know the list is very much simplified but thats basically it.
Sure there´s a lot of parts need to keep the power inside the engine like rods and you also need better clutch, maybe even better brakes

Vaatan Dahlbäck'i lehte ja seal on A6 2,7 kohta sellised huvitavad andmed:

Max. power 312 hp (230 kW) vid 5500 r/min Max. torque 387 lb-ft vid 2800 r/min

Price incl. installation 582 EUR excl. VAT
Note The software maintains full functionality in terms of diagnostics, engine protection and fault code memory. On cars with Tiptronic the ECU in the
gear box is replaced and the torque is limited to 420 Nm.
Max. power 330 hp (243 kW) Max. torque 390 lb-ft
Changes

transmission 165 EUR+VAT.
Price incl. installation 2037 EUR excl. VAT
Note The software maintains full functionality in terms of diagnostics, engine protection and fault code memory. On cars with Tiptronic the ECU in the
gear box is replaced and the torque is limited to 420 Nm.
Max. power 360 hp (265 kW) Max. torque 401 lb-ft
Changes
New E-proms in ECU, stainless steel exhaust (turbo-back) with racecats, installing bigger intercoolers, optimization of flow to intercoolers,
modification of air filter housing.
Price incl. installation
5772 EUR excl. VAT
Note The software maintains full functionality in terms of diagnostics, engine protection and fault code memory. Only for cars with manual gearbox. On
cars with Tiptronic the ECU in the gear box is replaced and the torque is limited to 420 Nm.
Ehk siis ilma kütuse, turbode vahetuseta on maksimum võimsus 265 kw. Ja nagu ma siin teemas viitasin, on S4-l ja A6-l on samad
turbod. Ilmselt ka ülejäänud raud on sama. Seega idee kohaselt ei tohiks probleemi olla ka sama jõud S4-st välja võluda.
S4-l on Dahlbäck'i info kohaselt viimane enne vilede vahetust tuuning selline:
Max. power 348 hp (256 kW) vid 5000 r/min Max. torque 392 lb-ft vid 4000 r/min
Changes
New E-proms in ECU, stainless steel exhaust (turbo-back) with race-cats, modification of air filter housing. Note! Cars with Tiptronic also
require a software upgrade for the transmission 165 EUR+VAT.
Ehk siis A6-e nimekirjas on üks asi rohkem - turbode vahejahutid.

265kw on väga hea number juba, enne turbode kallale minekut. Äkki on A6 coolerid väiksemad kui S4 omad? Otsisin korra võrdlust ka netist, aga ei näi
olevat. RS4 originaal rauaga on ka võimalik upitada 500hj ja tsipake peale, mis on samuti väga hea tulemus võrreldes originaaliga.

Kirjutas üks inglismaa klubiline kui küsisin, mis ta RS-iga tehtud on. Muidugi siin juures on veel kindlasti parem bensiinipump ja pihustid, aga
üleüldiselt väga palju jõudu arvestades, et auto on praktiliselt originaal
