By the way, thanks for this Arin. This made my day, unfortunately for Saki now I’m even prouder of the B8 S4 
Jspazz, you ran 12.4 on 93 and 12 flat on 110 right? That seems to be pretty consistent amongst stage 2 b8s. On that logic then a stage 2 b8s4 on 93 is comparable to a stock RS5 on 93 in the 1/4 mile.
Not a trick question I’m just trying to sort it out in my head. I wouldn’t imagine the RS5 would see 4/10ths just switching gas.
Yes, correct. I have no other bolt-ons, or rather, they haven’t made it on my car.
Even more intersting in all this that Audi says the new S6, which is likely the match of a B8 S4 on stage II on race gas is 420 hp at 6400 rpm, and 406 lb-ft at 1400 to 5200 rpm.
Saki text me if you do some filming tonight. An untuned fresh motor S4 has some break-in to do.
turns out…it’s still an S4 even when you post that. It didn’t magically turn into an RS 
Keep telling yourself that, buddy…
In all honesty I admit watching you car drive with the big fenders and big brakes and tuned suspension, there is always going to be something more impressive about an RS.
It’s weird… I know everything there is to know about what various mods have done to quarter mile times on B8 S4s. Don’t forget who entered, tediously, every little piece of data in the audirevolution.net/quartermile list. I will go head to head with you any day you want, no computers. Game for a trivia battle???
On the other hand, it seems it is you who is a little out of the loop on what the RS cars are accomplishing.
What is the fastest a B8 S4 has gone without a tune, just for interest’s sake? Because a B7 RS4 with clutch/flywheel/rotors and LW race seats and NO TUNE just ran 12.26 @ 112+. So don’t claim that race gas is some magical formula that only works on the supercharged cars. Octane allows for timing and allows for a cooling effect that helps the NA car just fine, thank you.
Don’t forget…your car is TUNED for race gas. That RS4 on race gas was not. Most people don’t bother with race gas tunes, and that is why it is ignored. If you’re always just a tank away, you’d better not do any highway pulls with someone…unless you’re going to tell them ‘WE HAVE TO GO TO MY HOUSE TO GET SOME C16 FIRST!’
I think it’s funny that you say you’re not a dyno guy, yet the very next post after this one that I quoted, you were very proud to own a B8 S4 for some reason because of a dyno comparison of an RS5 vs. an S4 with a 100 octane tune and a pulley.
would that 3.0T on 100 setup that you’re so proud of trap 125 mph? No? I didn’;t think so. Call me when you guys get deep into the 11s @ 125+. Then you can ‘be proud’ and talk shit. Until then, your platform is doing quite nicely. Certainly not worthy of this b.s. dick measuring with dyno results. If we want to roll out dyno results/measure dicks here…let’s not fuck around.
500 whp? Check
125+ MPH trap speeds? Check.
race gas? Didn’t need it. Tricks are for kids. 93 octane. Haven’t run the race file yet.

He bought it a year ago…already has 35k on it. He fucking loves the car. He tells me everytime he sees me lol. It’s a great car to recommend to people because it looks nice, is well built, is great inside, and is shockingly quick. Value is excellent, so everyone who asks me what car to get I tell them - new S4.
Explain what?
Sak/Jay,
You both make me ;D (smile)!
You both have your own opinions so I thought I’d throw mine into the mix:
B8 S4 vs. B7 RS4 (which is what this thread has become) I think it is almost certain the B7 RS4 with it’s 4.2l engine will be the more powerful car i.e. will most likely trap the higher speed with similar ET in the 1/4 mile and during highway pulls will probably pull on a B8 with similar ET… But I do feel the B8 has the advantage in a 1/4 mile race with its TQ curve… Lets be honest the B8 only does as well as it does because of its insane TQ curve… During highway pulls it’s clear that many cars with similar ET times are producing much more power and either catching and pasting the B8 or just begin to pull immediately in the pull! But all of the above is just my opinion! ;D
Okay so enough with the subjectivity by all and lets look at the data! Lets gather the fastest times for both the RS4 and S4 within the following categories, Stock, Stage 1/1+, stage 2/2+, and stage 3/3+on pump gas or race gas or both it doesn’t matter and see which platform is on top in most of these categories. This should be pretty easy especially with Sak’s 1/4mile spreedsheet (thanks Sak but my 12.0 run was on 94 oct not 110 just so you know… lol!) so we can determine at each stage which platform has the better times to-date.
What you’ll think?
b8 stock = 12.69
rs4 stock = 12.75
Not sure about stage 1 and 2 on the rs4, I know that one ran 12.2 with just some minor mods and no tune.
Fastest:
b8 stage 2+ = 11.76
rs4 stage 3 = 11.4
^^ Nice start but lets keep the generally accepted parameters of stock, stage 1/1+, stage 2/2+, and stage 3/3+ intacted. with that being said should also separate race vs pump so it would look more like this:
Stock
B8 stock (race) = ?
RS4 stock (race) = ?
B8 stock (pump) = 12.69
RS4 stock (pump) = 12.75
Stage 1/1+
B8 stage 1+ (race) = ?
RS4 stage 1+ (race) = ?
B8 Stage 1+ (pump) = ?
RS4 stage 1+ (pump) = ?
Stage 2/2+
B8 stage 2+ (race) = 11.76
RS4 stage 2+ (race) = ?
B8 Stage 2+ (pump) = ?
RS4 stage 2+ (pump) = ?
Stage 3/3+
B8 stage 3+ (race) = ?
RS4 stage 3+ (race) = ?
B8 Stage 3+ (pump) = NA
RS4 stage 3+ (pump) = 11.4
What defines a “stage” in the RS4?
Maybe…
Stage 1 = tune
stage 2 = tune + piggies/dps
stage 2+ = tune/dps/exhaust ??
Too bad there’s not more 1/4 mile time info on the RS4. Pretty sure I know all of them off the top of my head lol.
I was talking about my car…let me know if you’re out.
My guess would be as follows:
Stage 1/1+ - Tune, exhaust, intake
Stage 2/2+ - same as 1 + HFC/test pipes, headers, dps, maybe some LW components
Stage 3/3+ - same as 2 + Turbo/S/C
but again just a guess never fully understood what exactly makes up each stage! ;D
Speaking of RS5s…

Who wants to join me on Aug 18th?
Get to drive RS, S models at Monticello. Free event sponsored by Audi.
Let’s get some guys to go.
Just curious if any of you have tried using CarTest. It’s the ultimate bench racer, get the version 4.5 download since it’s free and works better than CarTest2000.
Plugged in the cars data (all specs including gearing, frontal area, CD, dyno plot (crank), using a 12" rollout, launch from 3000 rpm, etc etc). It’s pretty thorough, and simulates all parameters mathematically. Here’s what I get:
RS5 gets 12.6@112.3
The stock B8 S4 gets 13.0@106.6
B8 S4 stage I 93 gets 12.6@111.8
B8 S4 stage II 100 gets 12.0@116.5
The RS5 in particular, I used a 5500 rpm launch. If you use a 3000 rpm launch, the 60’ time goes from 1.87 sec to 2.00 seconds, which makes sense looking at the power up top and weaker torque. I’m curious if the DSG is tuned for this at launch. Noticed it hits redline in 3rd at 112 mph, basically right at the 1320…and top speed in 5th.
Look at that track…wow you should go.

bahh its all full up 
… I had my gf sign up since I’m not old enough to drive the cars. If by some stroke of luck she gets off the waitlist I’ll be there
Those guys in Russia having some fun. ;D

Same car above…Run against Bone stock M3.
It was a joke…expand is what it says. The rs4 dynos I was referring to dynod over 500 whp so they can’t fit on your chart of “lets compare some ridiculous unrelated shit”
