Mina leidsin sellise juttu.
If an integrated exhaust (non-divorced wastegate flow) is required, keep the wastegate flow separate from the main turbine discharge flow for ~12-18"
before reintroducing it. This will minimize the impact on turbine efficiency– the introduction of the wastegate flow disrupts the flow field of the
main turbine discharge flow.

Selline postitus jäi silma:
As a reference point most I5 ported heads I've come across in the market place will flow around 175-185cfm@28" on stock sized valves. I've seen
190-195cfm@28" peak figures on oversized valves with more area under the curve.
Over sized valves with welded up and reprofiled exhaust ports have yielded 200-204cfm@28" peak figures with again more area under the lift curve.
So assuming that the posted flow figures are at 28" and the transitions are nice from head into the initial runner entry then you will be hard pushed
to max out this exhaust mani hence my personal interest.
As for my personal opinion of cast vs tubular (not necessarily correct and open to other opinions of course)
The theoretical advantage of a tubular is that it will offer a more consistent delivery of air throughout a revolution of the engine giving smoother
spool up low down and reduced EGT's at the top end due to a reduction in turbulence as the gases meet at the collector. In the same token the cast
manifold has a greater ability to retain heat and will offer higher gas speeds again improving spool up, it's downfall being at the very top end of a
high hp motor (700+) where too much heat retention can be detrimental to EGT's. So unless going full on top end race motor it's much of a muchness
other than that the cast is theoretically much stronger and longer lasting for road use.

AUDI S2 RS2 EVOLUTION CAST TURBO MANIFOLD - K26 FLANGE
The Wagner Tuning Audi RS2 Evolution Exhaust Manifolds are a high performance redesign of the original RS2 factory manifolds.The original OEM
design reduced the exhaust gas flow to a power robbing 22mm inside diameter! Our engineers have removed the OEM bottlenecks and increased the flow
rating providing a continuous 38mm unrestricted path from the motor to the Turbocharger.This results in increased throttle response, quicker
turbo spool-up, and higher top end power capabilities.
Each manifold is constructed of the same OEM casting material as the original RS2 manifolds (EN-GJSA-XNiSiCr35-5-2 letter: D5S), and is also cast in
the same factory as the original manifolds to guarantee OEM+ quality! Each manifold is a performance work of art.OEM+ Fit and finish for easy
installation
The Wagner Tuning S2/RS2 Turbo Exhaust manifold features:
* Cast from High Grade OEM RS2 materials - EN-GJSA-XNiSiCr35-5-2 letter: D5S
* High-flow, pulse optimized for great throttle response & high power
* Designed for the “K26” style turbo flange mounting
* Additional 5mm compressor housing area allows for larger aftermarket Turbocharger mounting
* OEM Direct Replacement

Huvitav postitus jäi S2 foorumis silma:
Rusty
Aye, although mine's only 2.5", it's only the last metre and there's very little restriction before that
It also helps to dull the noise down a little as there's a change in diameter.
Theory is that the exhaust gases have cooled a little by the time they reach the narrower pipe and thus it has less of an effect and may even
help as it will speed the gas up a little, helping the subsequent exhaust 'pulse'.

Kas näiteks b5 biturbol pole originaalis midagi sarnast, et enne lõppu lähevad 2 toru üheks kokku. Ja selle ühe toru ristlõike pindala on kindlasti
väiksem.

Jamo
2 pipes flowing more is a myth, Pipewerx confirmed this when I had mine done, the main advantage of twin pipes is ground clearance
GazzaG60
jamo is correct. the 2 cat setup is for clearance and flow. without the cat being too big that it catches.
Keeper of The Kitten
Partly this is due to the split from one pipe into two pipes being less efficient than people may realise ...a single large pipe willl flow
effectively without the associated turbulence at any split into two pipes. The split pipe system is a manufacturing compromise as stated
above. Even better when you don't need any cats at all
Is a Single 3" just as good as a twin on a RS2 450bhp?

wastegate exit pipe to exhaust
As you turn the boost up there is more exhaust gases, doesn't matter how big the hotside is the amount of exhaust gases the engine produces are way
too much to pass through the snail. So the wastegate now becomes a crucial part in venting of excess exhaust gases to retain a sensible EGT. So the
bigger the wastegate the more exhaust flow you can bypass once at peak boost, to the extend that we once changed a 38mm wastegate to a 50mm on a 3071
with .82 housing and gained close to 40hp (37 iirc) at the top end.
Now the stock Audi wastegate is only 30mm so by the time it has gone through the less than ergonomic valve and round the poorly flowing chamber and
made it's 90 degree turn a 25.4mm pipe ain't far of the mark for flow.
Make the wastegate flexi pipe larger and it will benefit to certain degree firstly you will reduce the core temp of the pipe, secondly the pressure
drop will help scavenge some of the gases from the wastegate main chamber. Much like the design of a 2 stroke exhaust system.
However this is where the problem occurs the bottle neck is now the wastegate itself. It does not flow very well, I spend a good while
on mine reshaping the insides and reprofiling the valve. The end result being no more EGT peak spikes of a 1000+ celsius instead a steady max of
around 925. Still running the original wastegate pipe.
Leading me to believe that unless you are upping the wastegate spec by porting or purchasing a larger one then there is no real point in upping the
pipe diameter beyond stock.
As a reference point my mates silly 1.8t at 2.3bar of boost and 750hp see's maximum EGT's of around 768-775 celsius down the quarter mile and flat
out on a track. He's running 40mm internal dia runners to a twinscroll 1.06 backhousing and a 60mm wastegate. the intend being to turn the boost up
tweak the cams and add some nitrous for next season to bring the EGT's into the high 800 bracket as at the moment we feel it is too cold.

Mul on näiteks originaal "fleksipipe", ei ole seda toru seest eemaldatud, 5 erinevat turbiini/koja kombinatsiooni ja m6nega neist on 6nnestunud ka
päris märkimisväärsed j6unumbrid saada, ei ole kordagi olnud probleemi boosti kontrolli alla saamisega. T6si, WG ei ole originaal 20VT 34mm klapiga,
vaid Tiali V44 40mm klapiga.

Mina arvan, et ei pea WG (otse välja vool , surve alandus ) jooksma pikalt enne kui ühtib sumbutiga.
Mina pigem suunaks kõik heitgaasid lamdasse ja saadaks ajule õige lamda mõõtmis tulemuse (mitte poolvigase alates kui surved tõusevad piirini) , kui
ei mõõdeta wg väljundit lamdaga.
Aga WG võib siseneda ainult sell juhul peale turbot sumbutisse kui seal pole vastusurvet.
Näiteks
Turbo väljund tiiviku auk kkk-26 on 64mm = 32 cm2 (pindala=pii x raadius x raadius) x 2,0 bar (sealt alates hakkab WG peeretama, näiteks) = 64 cm2
Seega peale turbot lehter mis langetab surve nullini peab olema ringi pindalaga 64 cm2 = läbimõõduga 90mm.
Peale sellist lehtrit on vastusurve nullis ja võib kohe siseneda WG toru. + saab lamdaga mõõta kõiki heitgaase, (nii kaovad probleemid lõpu otsa
seguga)
