Anyone here running RS6 turbos?

[DAP]

does any one know the eta on software and fueling?

EPL can tune for the RS6 turbos now.

I believe EPL has tuning options already available.

ha! guess I'm to slow

[Crash6]

GIAC now has a file for the RS6 turbos as well, although I'm not sure as to it's public availability.

The S4 tuned by Jeff Moss that ran in this year's USCC challenge (results to be published next month) ran/is running modified RS6 turbos, Evolution Racewerks intercoolers, and GIAC programming.

the car didnt perform anything special either

[Bart]

Wow I can't wait until I get RS6 K04s....

[10SecS4]

the car didnt perform anything special either

And how do you know this? AFAIK, the USCC challenge results have not been leaked like the ETGP results.

I can't wait for the issue to hit the stands. That's all I'm saying.

[esss_pho]

anyone know the release of the programing...i am trying to get all my stuff together and epl is way to far from me

[ss4]

and how is your car running?

My car has just dynoed again at GIAC, further tuned, and found another 30whp to a total of 535whp and 525 wheel torque. As you know, that is about 100 wheel horsepower more than any VERY strong RS4 turbo setup. So if 100 whp isn't "anything special" to you, sorry. Jeff from Torque Factory will post dyno plots very soon as the fueling kit will be released in upcoming weeks and is just finalizing the pump gas tune.

To put it into perspective, my previous setup that got me several 11.50 quarter mile times at 123 mph did 440whp on the same Mustang dyno at GIAC.

If anyone claims that they can get 500 whp from RS4 turbos, I would love to see it and a sub 11.47 time slip(at approx 3600lbs inc. driver) The closest I ever saw was Diego's car (same AWE RS4 turbo setup as my previous) tuned by Jeff that did 473whp on a very friendly dynojet and only 430whp on GIAC's dyno the same day within a few hours.

Bottom line: The new RS6 turbos and Torque Factory fueling kit makes 100whp more than a well tuned RS4 turbo car. All these numbers are with race gas BTW
thanks,

[Crash6]

I don't have a lot of experience with these engines yet, but how much can the bottom ends take? Do RS6 turbos necessitate (at the least) new rods?

[esss_pho]

the general consensus is that above 500whp rods are necessary

[generationjdm]

Sorry i was talking about the tq factory drag run not the road course my fault

I agree with the rs4/ko4ss will max out at 430-440whp, i wasnt refering to your car...

no problem. thanks for clarifying

[ss4]

I would say yes; I installed Pauter 4340 rods and reused all the factory pistons and rings. Also, since I had the heads off, I used 034 Motorsports head gaskets to lower compression by .7 and replaced all engine/tranny mounts with 034 Track Density variety.

[Boris]

how much power we talking about at wheels on 91 ?

Is first and second gear still good/./? brutal fast?

Just wondering how much power its making 2nd gear at say 4000 rpm..would this setup be fun for scooting around on streets? Or is it more highway friendly?

why would you want to lower your compression..wouldn't that affect your off boost response...and did you install the rods yourself?

I'm guessing about the same power as a RS4 turbo car on race gas; probably a little more. The driveability is as good as stock and we have seen 20psi of boost by 3500rpms on pump gas. First and second gear feel amazing with little if any lag. The freeway is exciting as well; very well rounded in my opinion with no major loss down at low rpm's. I can only speak this of the Torque Factory/GIAC fueling kit for the RS6 turbos. I haven't seen or driven any other RS6 car at this time...A close friend of mine has the VAG GT25 turbo kit and he is struggling with the car making any real boost until 4500 rpm's but hopefuly we can work on that as these turbos are slightly smaller than the RS6 units and should spool very quick.

What fuel was in the tank to get that extra 30whp? Just asking since you didn't list a octane being used. Best to compare #'s using the same octane in both cars and I know most of everyone else tends to run the highest unleaded race fuel.

same gas for both tuning sessions (C-16), just had a little more time to tune as we only had the car running three days before the USCC event. We are also tried out RS4 cams and I'm not yet convinced how much of a difference it made. I used VP race fuel, C-16 but MS 109 would have worked about the same.

105 octan in place of C16? If a car is fully tuned for 117 octane it would run like crap on 105, same thing using 117 in a car tuned for 105. There is a 16 octane difference in motor octane ratings between those 2 fuels. Theres even a huge difference betwen the 110 octane I run and C16.

I tuned on C-16 on the dyno, filled up with MS 109 and headed to K&N to start the USCC event; and made some very slight changes for the octane difference. Car ran perfect with MS109 on their dyno. I agree that C-16 is a much higher octane fuel but some time not needed depending on the recquirements from the motor. We would have made more power on C-16 but wanted to try and do well for the smog test after the dyno
you will see the numbers soon in next months Sport Compact Car issue (Oct 18th press release for the Dec issue)

why would you want to lower your compression..wouldn't that affect your off boost response...and did you install the rods yourself?

I lowered the compression because I push the car real hard all the time (already tested to 37-40psi by accident!) and figured it wouldn't hurt. The off boost response seems fine as the compression drop was minimal. The car currently runs 25 to 29 psi depending on the gas (91 or race fuel). I don't think headgaskets are a must but I decided to try them by suggestion from Jeff Moss at Torque Factory. It also gives us a little more "headroom" for higher cylinder pressures IMO.

More head room and more adv timing can be used during off boost which makes up for the lowered compression at that point.


Brent did you guys run bottle for that event?

[10SecS4]

Sorry i was talking about the tq factory drag run not the road course my fault

And I was talking about the car's overall performance during the USCC event, including the dragstrip runs.

[lil' is 300]

I think he's referring to the TF RS6 drag runs at ETGP 07. I think he's mixing up ETGP and USCC.

Brent, do you use stock compressor and turbine wheels on your RS6's?

[Boris]

20 psi at 3500? Shoot that sounds good to me

I just bought a pair of ko4s, maybe I should sell them

[ss4]

Do it! And with my RS6 setup, you can still use the RS4 inlet pipes and everything else is just like a RS4 install except a slight downpipe modification to the bolt holes

All 100% stock RS6 internals, modified wastegates, and RS4 compressor housing to make them fit identical as my old RS4 turbos using the same inlet pipes for a perfect fit

I'm not quite sure what he meant about the drag runs; some clarification would be nice...

[ss4]

anyone know the release of the programing...i am trying to get all my stuff together and epl is way to far from me

contact Jeff Moss at Torque Factory; he will have a complete kit that does not recquire your car to be at his shop and will not need a custom tune. The whole fueling kit can be sent to you or your installer and your ECU can be flashed with the software. This will be a complete kit with pump, race, and boost controller options already loaded and ready to go. The maf housing/filter assembly is a work of art

I flipped through a copy of this months SCC in CVS today and saw a pic of your engine bay. Looked clean.

Do you think there are ways to make the stock compressor housing on RS6 work? I got a set but I don't know what to do for the housing. The TT 225 K04 compressor housing is a perfect fit and looks like it flows more... just based on briefly comparing compressor maps.

edit...just realized...10 freakin pages.

[tigasTT]

Not bad for a post that started as a query.

Thanks for the indulgence guys! :)

in for pics of that fueling kit

[lil' is 300]

It's just a basic cone filter and a MAF...not much else to see....

[esss_pho]

so when will it be released to the public...anyone know

[lil' is 300]

Don't you have your RS6's listed for sale now?

I have no idea when it's coming out, last I heard was a few weeks ago they were making some final decisions on the kit. My gut tells me the release will coincide with either USCC or ETGP.

[esss_pho]

i have my rs6's in the mail...but i can get many more lol

[lil' is 300]

Sick. If you can get these turbos at that price consistently I don't know why anyone would bother getting RS4 K04's when for an extra few hundred you can get turbos that do well over 500 wheel!

Good stuff man, more affordable power = more fast B5's. And thats what it all comes down to in the end...the advancement of the S4.

Correct me if I'm wrong, but SS4 appears to running some type of K04/RS6 Hybrid; RS4 Compressor housing and RS6 Exhaust.
