[Spidercat]

just fyi, mi021le on this board has 461 awd hp 530 tq (tq from different dyno. ) per his sig block.

Nice car you've got there. If anyone wants an RS6 with all the bells/whistles already in place, that's a nice one! Good luck!

[ben916]

damn...!!!:bigeyes:

Any videos for interior and/or sound???

[SAF]

Is the advertising removed?

[RS6Dawg]

The vinyl is still on the car. People just drool with the vinyl. If you'd prefer no vinyl, I'll take it off and have it fully detailed. Car will be fully detailed before delivery regardless. I don't want to mislead anybody, this car is immaculate and has been well cared for.

More importantly, does the car have OnStar? :vhmmm: If it does I would think you would have mentioned that first and foremost.

[vangelis]

what is the (electronic dump valves)??

[RS6Dawg]

No disrespect man but, who gives a shit about Onstar? The car does have it but I never activated it. If your excessively speeding, Onstar WILL call the cops on you. It's happened to my friend. Fuck Onstar...

The electronic dump valves are welded into the exhaust where the resonators used to be. Hit the switch under the dash and your bypassing the mufflers. Also I had this gold foil put all around that area under the car to reflect the heat. All of this was done at 034 Motorsport. They are DMH low profile exhaust valves..google it..they are the best dump valves I know of. Thanks guys

I'm going to look into those dump valves! Thanks for the link. I'm assuming it's as loud as a mofo when you bypass the mufflers.

are there any power advantages/disadvantages to bypassing the mufflers?? regarding backpressure, ect?

[RS6Dawg]

The low end deff. suffers..Screams up top..its super loud, tons of turbo spool sound. I did it for a little more flash for the Gumball. I love it.

[dmross]

Why would the low end suffer from reduced back pressure? Your turbos should be able to spool up quicker with that setup. Perhaps it's messing with the o2 sensors and causing the ECU to screw up AFRs?

Either way, good luck with the sale. I sent the link to a few friends. :)

I keep reading this in several forums. A lot of people are being mislead I think. Exhaust back pressure makes the turbos spool faster. More restrictive exhaust will have faster spool and more torque...to a certain point. Example.. My rs6..I got the catback before the dp's. It had GIAC software...had it dynoed without dp's..then put them on, dynoed it, and we basically traded 15wtq for 15whp. So by putting the dp's on we lost 15 tq but got 15hp.... opening up the exhaust near the motor will deff make more hp but not faster spool....Back pressure...Think about how a turbo works...it makes sense.

Thanks for looking and for passing it on.

[DHall1]

Not really.

Backpressure is the differential between the turbine housing and the downpipe pressure.

Corky Bell.....max boost. A must read for everyone.

Full flowing downpipes can always make more power in a turbo application.

Your tune may have changed or sensor temp operation for the change in power.

I agree..full flowing dp's make more power..not torque..also what sensor do you speak of..EGT? Thats in the manifold.. so by changing the dp's,how is that affecting the sensor before it?
My car is a classic example....less back pressure.(dump valves).less torque. Its a fact!!!!

[MarkusRS6]

basically torque x rpm = power

Torque is measured; Power is calculated

[RS6-4dr911]

As a rule backpressure is almost always good for low end torque but bad for high end power, faster spool or not. Not sure why, just know that's almost always the case.

However, don't run out and try the banana up the tailpipe trick, too much of a good thing, etc.

[RS6-4dr911]

Bingo !!

[DHall1]

Sensors

No two dyno runs are the same. Place time and distance between the runs and your even further away from apples to apples.

All the sensor readings between two time periods could have a large change in outcome. intake temps, coolant temps, egt temps prior to the run all play a role in ecu map selection. Just a 7 degree change in intake temps will vary output a great deal.

I'm sorry, but this is simply backwards. In a turbo charged car, the greatest restriction in the exhaust path is the turbine. For anything after the turbo, you want the least restriction possible, because the only thing you can do is make the turbine restriction better or worse (read: increase or decrease the pressure differential). In a perfect exhaust system on a turbo charged car, the only restriction is the turbine itself. This will yield the most flow, and therefore the most torque potential at any rpm.


used same dyno same day....

That is only one part of the whole puzzle. How likely is this possibility; On the second run when you added the downpipe, the turbo spooled quicker and the ECU pulled back boost to keep it from overshooting the boost target, because prior to that the learned wastegate duty cycle was much higher. It might have even overshot boost targets and pulled back as your engine was reaching it's peak torque range. Your turbo doesn't hit max boost until later in the RPM band, past your engines point of peak torque and out flows the old setup making more power. Viola, less tq, more hp.

If you use a dyno to compare torque and power, it is critical to log temperature, timing, AFR and boost to determine if the comparison is valid.

Just my 2c. At the end of the day, isn't it better for you if you can confidently answer, "no, the exhaust dump tubes add power across the entire power band!"? :)

[BLITZEN]

Man I love those wheels. What brand/style are they?

[DHall1]

Bingo we have a winner.

look, I don't care what you've read. I experience it. When you open the valves, the car dogs off the line...Why? less back pressure. Go cut your exhaust off at the resonator and tell me what happens. Also I've been in a B5 S4 with no exhaust.. just downpipes and It was a dog off the line too. But according to you, the torque increase from no back pressure should have melted all 4 tires . It takes more than a fancy write up to convince me. The guys at 034 Motorsport (who installed the dump valves) told me "lack of back pressure" is exactly why the car dogs off the line. Are they wrong? They only do this for a living. So many people have no experience, read some writeup online, and all of a sudden they're an expert. Like I said, go cut off you exhaust and tell me what happens..

[Spidercat]

RS6Dawg,
I'm thinking about the DMH valves just for the sound. Have you ever had any problems with the valves opening/closing? May be a stupid question, but can you open/close them with the engine running? Just wondering if the servo motor/actuator can overcome the exhaust pressure. Any pics of your set-up from under the car?

[DonS]

Hmm, doesn't the ECU adapt to changing circumstances? If so, a radical change in exhaust pressue (or temp, or octane, or...) take time for the ECU to adapt. Small changes - ECU makes fast reactions. Large changes - and ECU makes slow and possibly overreactive changes. Maybe ECU is overreacting upon opening those dump valves. My 1c guess.

Regardless, its got to be way loud and lots of fun. As my buddy told me after hearing my stock RS6 - "We should punch some holes in the exhaust to make her sound mean."

[dmross]

look, I don't care what you've read. I experience it.

Well, in that case, the earth is flat and fixed in space.

laws of thermodynamics > you


When you open the valves, the car dogs off the line...Why? less back pressure.
Why? Lack of tuning for the change.


Go cut your exhaust off at the resonator and tell me what happens.More power and quicker spoolup happens. This is why I run a cutout on my track car and on my brothers car. Why do you think people run cutouts to begin with?


Also I've been in a B5 S4 with no exhaust.. just downpipes and It was a dog off the line too. But according to you, the torque increase from no back pressure should have melted all 4 tires . It takes more than a fancy write up to convince me.
Yes, it should have made more power across the board, provided you adjusted the boost control and fueling/timing to take advantage of the greater flow potential. Nothing "fancy" about that, it's pretty straightforward. What does it take to convince you? You can pay me if that will validate your learning.


The guys at 034 Motorsport (who installed the dump valves) told me "lack of back pressure" is exactly why the car dogs off the line. Are they wrong? They only do this for a living.No, they probably told you something different or you misunderstood. From their own website, in the description for their 2.7t downpipes -

"Most downpipes on the market are not even 3" in diameter, most only 2.5". ... We've spend considerable time engineering a staged transition from the diamond shaped turbo flange opening for smooth, restriction free flow out of the turbo."


So many people have no experience, read some writeup online, and all of a sudden they're an expert. Like I said, go cut off you exhaust and tell me what happens..I have, and it made more power and torque.

You know what the problem is? The "online writeups" you are referring to consist of misinformed posts like the things you are writing in this thread. Most of the people who actually know don't bother correcting people like you anymore because another will just pop up in your place and pick up where you left off. Conventional "wisdom" is often wrong, but people keep believing stupid crap because it's easier for them to stomach and doesn't challenge their ego.

I wonder if Corky Bell has an online version of his Maximum Boost book.


Its really very simple as I said in my first post.

But lets not keep beating the horse. Its dead and 6 links above should keep everyone reading till the cows come home.

Nice work Moss
