Stage 2+ A/S4 vs 997 Carrera 4S
While I was waiting for the green arrow onto the highway a silver 4S pulls up along side in the accompanying lane. I saw the guy looking at the car, I had a feeling something would go down as soon as we got on the hwy.
We both get on in a brisk manner, right onto a nice long clearing of open lanes, I wait for him in 3rd gear, we honk off. We were pretty even up until 110 or so where I started walking him. By 130 or so I was up a car and a half.
We both shut down, he doesn't want to go now more, tho he did throw a thumbs up.
From what I could tell, all he had was an exhaust, the thing was pretty loud.
My car only has downpipes, a custom road tune and dv's. Stock k03 turbos =). Next week ill have my water meth hooked up, that's good for another 15-20whp when not tuned for it.

Generally Stage 2+ S4s put down about 290-300awhp. But I do not have a off the shelf file like everyone else.
The car has been wide band road tuned, over 50 revisions to the file. Injector duty cycle in the 110-120% range and some advanced timing make the car fly.
I suspect it puts down around 340awhp, the car is an A4, its a bit lighter, also I have a 5spd not a 6, which is quicker geared than the 6. The car is good for a very low 12 second ET pass. I just wish I had some intercoolers and a exhaust.
I'm going to be dynoing the car in the near future to give myself a baseline to work with. I'm staying with k03s until they blow.
The fastest k03 car did a 12.2 pass at 114 with a tweaked GIAC tune.

Heh Carl, I'm 99% I saw that particular second hand black C63 on SSP, baseball cap and glasses hmmmmmm.

If I only had the extra funds to finish up project Talon.
I do have a big treadstone intercooler here for sale ,never used ,for cheap if you r interested. 3" thick!

If he gets his injectors, intercooler,tuning,and exh right ,he'll be in the 11's with a much higher trapspeed. Those are some very important keys that must all work together nicely in conjuction with his A4's present gearing hence easily hitting triple digit speeds in the 1/4 mile...

Carl, Id need a 2in 2 out core. Either way, Im trying to save up for some ER intercoolers.
http://www.evolutionracewerks.com/?q=node/61
4.5" Garrett cores. They are the best you can get for a 2.7t.
In regards to the injector duty cycle, I have a ton of these at my shop, if one goes, I swap in another. I would have to take a few weeks to tune for 630cc injectors on k03s, I rather just stay with the stockers paired to my 044.

I have a 5 speed out of a 2.8 A4, which is quicker geared than the 6speed out of the S4.

Good kill....but I can almost guarantee that you don't have anywhere near 340 awhp....if you meant hp to the wheels. Not even close...wideband tuning only tells you your afr's....and it sounds like you're still on a chipset via OEM Motronic.
I've had 2 built S4's ,and currently buidling a 95 S6 .
Tony Chick of EPL is a good friend, so I've been to enough dyno days @ EPL to know what Ko3's w/ 2+ tuning,(piggies,FMIC and water meth) can put down at the wheels. You're very top end limited.
365-375whp is what a Ko4'd cars w/ just a tune & fueling do on a Mustang.
You're most likely at 325-40ish at the crank which is about 265-70ish at the wheels., and thats a big maybe .
Also your A4 5 speed has longer gears than the o1E 6 spd of a B5S4....so you don't have as good 0-60 and 1/4 mile times as a similarly tuned B5S4...not sure where you got that info. Also, your 5 spd doesn't have a widened 1st gear,so its not as strong.
Your injector duty cycle is insane. You must be ringing your knock sensors like crazy. You ought to hit the rollers and see where you're at.
Either way....glad to see a fellow Audi guy.

I will be dynoing the car soon, there have been other stage 2+ cars which put down 290whp. Like I said, I don't have a off the shelf file. The car has been wideband tuned with numerous revisions. Another k03 car with this exact same file, just with more bolt ons put down 390 wheel on a mustang dyno.
![thumbs](https://mbworld.org/forums/images/smilies/thumbsup.gif)
Its a extremely aggressive tune, we don't sell it, I put it on my car because I don't care what happens to my k03s.
Fyi, Motronic 7 is a very capable platform in the right hands. That and a healthy K04 car with proper bolt ons will put down OVER 400whp. Like I said, tuning is the key.
1.8t 01A 5speed has shorter gears than a 01E 6spd.
2.8 01A 5speed also has shorter gears than a 01E 6spd (1st, 2nd and 3rd, while 4th and 5th are longer.) Hence why I have a 2.8 tranny bolted to my motor and not a 1.8t.
Mind you I have a 3.89 final drive and not a 4.11 like the S4.

OK, got it on the 2.8 V6 5 gang. Not too familiar w/ that tranny as I don't think they made too many manuals in the late 90's for the a4's.
Aren't you worried you're going to grenade more than the Ko3's ? I guess if you've gone to bigger injectors you'll somewhat safe....but stockers ?
Now you've got me curious to see what your car will put down. Please keep us posted.
PS- There's sooo many guys that have killed their KO3's w/ just a GIAC X chip that's why I'm amazed a Motronic tune for Ko3's can get pushed even more, but anythings possible I guess.
PS- Here's mine.

Nice Rota P45's. I'm getting Rota Grid wheels for my car =D.
When you own your own Audi performance shop, have about a dozen pairs of k03s laying around, and another separate block for a future build you can run a aggressive file. The motor won't blow, my partners car has been running the same tune for over 35k miles with 0 issues what-so-ever. The only thing you have to worry about is keeping a light right foot. (MPG can be baad with any boost haha)
You'd be surprised how conservative off the shelf tunes are. They're made to make power safely and reliably, not to compromise the components of the motor. Theres always that head room that can be exploited with a tune tailored to your car =).
Btw, how long ago did you pick up your C4? Is this the one that sold on audizine for 7kish? I was looking to buy that very car.

The injectors wont go...your motor will. i would highly recommend not beating on it until you swap injectors or youll be posting a thread on "how my motor blew". With turbos its all about flow and minimal back pressure so you should ditch the stock exhaust, intake and intercooler. tic, tic, tic...

If it is really posting low 12's in the 1/4, I would believe it is putting out 340ish or more at the wheels. I saw a stock 417 hp M3 V8 run a 13 flat at e-town back in the spring. My C32 ran 13.1-13.2 that same day. I don't have 340 at the wheels but am running a healthy motor. Saw low 12's in a 335i that was running about 380's hp. I think A4 would need similar power to trap in the low 12's.
As for the 120% injector duty, my understanding is that once your at 100% the injectors are open and stay open. It cannot flow more than 100%. Result is lean FAM and eventual burned valves or holed pistons. Maybe Audi does this differently? You can improve flow with higher fuel pressures, etc to solve this on same injector. 100% is hard on the injector and the valves as the fuel is hosing the intake valves when they are closed.

I'm running this Saturday at Waterfest 16, hopefully it won't be too ridiculously hot. Whatever the result I will be posting the time slip here.
I actually ran with an E55k last week, was pulling on him pretty well over 100, had to let off for traffic though. I'm sure the car traps in the 114-115 region. (I have my meth hooked up now too
