Hmm- Depends on the RS7- I'll take that bet, we will figure out what for when you come east in October

Your car is an outlier for stock performance figures (I still think your wheels are helping a smidge )

Put a showroom stock RS7 and a showroom stock S8+ on the same track, I'd bet $100 they're within .2

Fair enough but you're still on, now will we see it happen ?

Probably the same way we'd see a showroom stock RS7 vs a showroom stock RS7 Performance lol

One can dream...would be an awesome sight to see!

[Chris Morales]

I would love to see a lineup of all the current S/RS models (and the R8) in a world's greatest drag race format.

But on point with the S8+, I'd lay solid money that it edges a standard RS7 in the 1/4. No more second fiddle. Hopefully at some point we're all making 800+ with upgraded snails and these differences with the stock hardware become footnotes.

I'm even giving the RS7 a couple tenths so I know my $100 is safe

But my non-wagered guess is they are dead even

RS6 always tests slower than the RS7 prob because its Cd .35 vs Cd .30 - Find one here in VA, has to be someone in D/M/V area with one here on the forums- I'll use pump gas and turn off the stage 1 file

What does the S8+ run in 1/4 ?

My guess is the mph will be improved and the ET not so much ?
Has anyone ran one yet ? Not talking magazine figures as I don't rely on them .

I've yet to see an independent guy run and post a slip for an S8+ anywhere- And before we get too far ahead of ourselves on how much better the + is than the regular S8 was, the 13-15 S8 was never only 520 hp, MT dynoed one when testing it in 2013 because, and I quote, "We even took them over to K&N Filters for a spin on the dyno — after all, one proved so damn fast, we just had to verify the numbers". The S8 has non-P RS power, I think that's been well documented, so if anything the + is maybe 40hp more than what you 2 guys have in your 13/14 models, and as I am with the Performance version RS, I'm still skeptical of that

http://www.motortrend.com/cars/audi/...bmw-alpina-b7/

This is not an S8 bash, please don't think that's where I'm going with this, we're bench racing, debating hypotheticals, it's all in fun, and in the end I may lose $100, but I'll all but guarantee a + ain't running better than 11.21...

And I agree 100%

I'm whiling to bet the S8+ will not run much faster than my Regualr S8, although the mph will be 2-3 mph higher, I ran 11.6 on serious 90* heat on almost 3000DA.

Another thing, my S8 dyno 9hp & 13tq more than the RS7, both being stock 100%.
Hence why I'm curious to have a stock RS7 run with me at the track .

[cobrario]

FWIW I ran 11.21 at just under 2000ft DA - these cars are interesting in that I made 11 passes in total when stock, DA varied from 500 to 2000 and my times all stayed within .07 sec

That's strong 💪🏿
But I'm manly referring to down here in GA which IMO air is totally different then up there in VA ..
My stock GTR best time ever around here was 11.4@122 and as we all know most GTRs run 11.0's and some in The 10's in stock form!

FYI apr stage 2 S8 on race gas best time [email protected]
Belongs to my local friend.

That's the smart way to do it. I'm leading with my chin.

I don't think it has to in order to beat a stock RS7. You hold the (unofficial) record, right? And I'm not clear on whether that was with stock wheels/tires. I think 11.4s are more typical for stock RS7s. But I'm not bench racing records or two cars at different places at different times; I'm bench racing an S8+ and an RS7 in the same place at the same time. There may never be a comparable record laid down by an S8+ because (apparently) people don't f-ing race them.

I saw that video you posted, noting it was against an RS6 P (not standard RS6/7) and that the S8 left a little late. But I also saw these videos, which don't seem to jibe with that result:



The above video was clipped from the end of this video:





Fast-forward to 0:30:



I think the S8+ really benefits from that 6800 rpm redline compared to the 6400 rpm redline in the earlier "nonplussed" cars like mine. With the same drivetrain as the RS7 P but a couple hundred pounds heavier than the RS7, I have to think the S8+ should be a smidge slower than the RS7 P. But I have to think it's at least an equal of the standard RS7 now in a straight line. I admit my position requires the truth of the proposition that the RS7 P is more powerful than the RS7 - otherwise, the S8+ is just now a standard RS7 with 200 lbs of extra weight to haul.

I'm enjoying this debate but as Chris mentioned, that is an RS6 Performance and the S8+ did leave later.

I still feel an S8+ is either the equal or within .2 of a regular RS7

And Carl, you know you're one of my favorites on these boards, but you can't continue to think stock RS7s run 11.2s LOL

You're the only one who has done it (and your ride wasn't showroom stock ). I think it's more realistic to say a showroom stock RS7 is running 11.4-11.5...which I'm willing to bet an S8+ could match (or a tick or two slower) at the same track, in the same conditions. Which is my wager

And by the way, the S8+ was only .2 slower in the 1/4 to that RS6 Performance..

[cobrario]

Fair enough Mick, I found a guy on the FB group with a +, asked him if he ever tracked his car and...crickets ? I think the real debate may be not if a + can hang with an RS7, but rather has/or will anyone with a S8+ ever run it to give us an answer ?

And Chris, I saw those videos you posted as well, but they didn't support my hypothesis, so I ignored them

[Chris Morales]

You are so right - no one drags an S8+. It's confounding. This will remain pure fantasy, and we'll all get to keep our wager money.

A few more observations though:

-m4xm1l10n's 11.681 ET at 2700 DA may already be within .2 of a typical stock RS7 in those conditions. It may not even take a plus to win Mickey's bet. But I suspect that's the best stock time we will ever see for a non-plus S8.

-Carl, that Top Gear video you posted actually seems to prove Mickey's bet is a winner. Freeze the video when the RS6 hits the finish line (see pic linked below). The S8 looks to be about 50 feet from being tied. For reference, the RS6 is 16.3 feet long. At 120 mph, a car is traveling 176 feet per second. So the S8+ finished approximately .28 seconds behind the RS6 P. I think it's obvious the S8 started a split second later than the RS6 and that at least .1 of the difference comes from that delayed start (a .1 worse reaction time). So the S8+ seems to have finished within .2 of the RS6 P. If so, now a standard RS7 needs to be quicker than an RS6 P for Mickey to lose.

Edit: I just caught, as Mickey noted, that the end of the video lists ETs that are .2 apart, apparently all in the 0-60.

https://photos.app.goo.gl/jRvl6e59x0VcuWK92

-Carl, I saw that you ran a 7.19@100 1/8th during your 11.2 stock run. In the 1/8th, that's the same ET and 1 mph faster than I could get in the winter (-1000 DA) with my stage 1 S8 on 93; that's quicker and faster than I can get this summer (2000 DA) with my stage 2 S8 on 93. If that's how fast stock RS7s run, forget this whole debate and just take my money. Even 100+ more HP at the wheels doesn't overcome the RS7 advantage.

[m4xm1l10n]

I will state this!
My S8 will run low 11's once temps cools off around here come winter, I think this car is a freak and That's my goal.

[Chris Morales]

If you're still stock then, that would be nuts. That's what stage 1 S8s run. But apparently a race gas stage 2 S8 is only good for low 11s where you are.

Hopefully you won't stay stock, you'll have the 104 tune with stage 2 by October, and you'll run 10.50s at the get together in MD. Give those RS7s a hassle and bring a little diversity.

I think I read an APR person explain that the stock tune allows for quite a bit of variance in boost based on ambient conditions in order to achieve similar performance no matter the location and weather. Once tuned, however, the car runs closer to the limit and doesn't have as much room to adjust upward. This would explain the consistency Carl mentioned on the stock tune in varying conditions.

[cobrario]

Sean and I are hitting the wanna go fast 1/2 mile event next Saturday so we will have lots more data points for a Stage 1 v. Stage 2 RS7. Don is coming up to record and hang with us so it should be pretty awesome time - I'm certain we will have lots of good info to pass on.

[Ze_Nardo6]

And Chris, I saw those videos you posted as well, but they didn't support my hypothesis, so I ignored them

LOL

[cobrario]

Your car is an outlier for stock performance figures (I still think your wheels are helping a smidge )

I had to move my stock wheels/tires around to a storage spot and for grins I weighed one and my spare Rohana wheel and tire that I put together- The stock wheel and Pirelli 275/35/20 weighed 56.4lb, the Rohana & Michelin PSS 275/35/20 weighed 52.6lb, so 3.8lb each- how much that helps...? I think the main reason my car went so fast stock is because

[Chris Morales]

Yeah, I wouldn't attach much performance gain to a 4 lb unsprung difference per corner. 56.4 sounds hella light for the stock setup. My stock 21s weigh 35 lbs each, so it's 65 lbs+ per corner with tires. Interesting too that the RS7's stock tire height is 1" less than the S8's, effectively making the gearing shorter.

I'm getting some 21" VS Forged rims that I hope will cut 15 lbs per corner. Pictures show them weighing in the 20lb range. From what I've read, what really matters is weight closest to the outside of the wheel/tire. If the weight savings are what I hope, this should be an example of nearly the best performance improvement one could hope for from rims on these cars.

LOL fair enough. To Chris's point, those are light for OEM! I thought the RS7 sported 21s in stock trim? Or is that a different package?

[cobrario]

mine had the standard 20" factory wheels which happen to be forged wheels (Probably rotary or flow forged like my Rohanas), hence the low weight.

[limeypride]

Yes to the 21s, at least for the Performance model.

Last night at the track

Stage 2 APR with 104 map

[3rdBNCC]

The database is updated. Awesome job Kevin!!!

[Ze_Nardo6]

Wow that is consistent and FAST! What was DA?

[3rdBNCC]

Wow that is consistent and FAST! What was DA?

1484 its on the database

[DGVR6]

Wow those times are super consistent.. what is the highest trap for a stage 2 rs7 on 104?

[3rdBNCC]

135.47 is the fastest on stock turbos. 135.56 with upgraded turbos. It's on the database file.

[DGVR6]

Seems like it'll be good for 9.9 in good weather. This fall should be interesting

9.9 is pretty much maxed for a stock car with no roll cage lol

[cobrario]

yes it will, and you'll not be able to run too many 9.99's or better without a cage unless you just do private rentals, most tracks don't bug you too much at those.

[3rdBNCC]

If I break into the 9's this winter, they won't bother me at OSW. They have already confirmed this. At best, I will be high 9s with this boat and probably not consistent. We shall see.

[DGVR6]

I don't think it'll be consistent 9s but with 135 trap it can happen. Really.. all you need is probably 20-40 more HP with some weight reduction and it would be pretty consistent with a 1.4-5 if iats are controlled

[Chris Morales]

Keep in mind that a TCU tune is coming. Not sure how much that will help a 104 RS7 that is dropping 850 lb-ft at 3000 rpm and already pulling low 1.5 60fts. But maybe there could be slight improvement out of the hole. On the shift rpm side, I'm not sure that short-shifting wouldn't be better. The 104 dyno charts on APR's website seem to indicate a HP peak around 5000 rpm. By 6300 rpm, there seems to be the same or less HP than at 4800 rpm. Interesting that the TCU upgrade for an S6 with RS7 turbos calls for short shifts in the higher gears.

Going from 10.25 to 9.99 is asking a lot.

Good info there Chris. I honestly don't expect to go in the 9's with the car. But, we a few tweaks to what I have already done, I think we can get the car into the very low 10's for sure. Even just getting out in a more favorable climate will help. Regardless, its a blast getting on the track and trying to go faster each time!

I'm not ruling your theory out at all, but I have a dyno sheet, albeit a half baked one because they couldn't stop the car from downshifting, and on the one decent 4th gear pull they got the power curve was still increasing until I hit the limiter. Owner experimentation is the key to advancing this platform it seems and to this point we've had very little, guys like Don, Kevin, Mickey and you are all helping push the 4.0TT further so kudos & thanks to you all.

We have a solid, core group here who all just want to go fast in their respective class. That's what it's all about, all on the same team despite what software/hardware we're running.

We want to see full weight, stock turbo RS7s in the 9s and full weight, stock turbo S6/7s in the 10s.

Can't wait for better weather!

APR tune question. Well it happened, despite a good relationship with my dealer I believe my ECU was reflashed and my APR stage 1 tune is now gone. I had the turbo lubricant line TSB/recall performed which required a ECU update. My remote now reads EMCS not activated. My original stage one was back in 2014. There is a new Stage 1+ for specifically for the downpipes offered by APR but I have heard it will work without the downpipes and is stronger. Anyone running this stage 1 with or without downpipes?
