Every second...

 

Correct, no major issues. I have had a few nuisance items fixed and a couple of minor engine related items fixed under warranty.

Overall the car is great to drive and has that typical German feel. I do love having traction no matter the conditions and the mid-range torque is incredible, making this car feel quicker than it really is.

 

nope, the cl-s went back to stock and she's long gone.

you wanna buy his kids??? fucking sicko...

 

wow your girls have gotten SO big!

welcome back Steve

thx for pointing out the Administrative oversight

 

Welcome back.. love the car.

 

Heya Stevo!

 

Cool and excellent choice. I see you made the move to 4-Door AWD turbo power as well.

 

Thanks and yes they have grown up. It is hard to believe what things were like just two short years ago.

And no big deal, as mentioned, I kinda expected it in my long absence.

 

Thanks, as always it is great to see familiar names.

great pics and great to see you around again. I may be jumping into another J Series vehicle as my main car, so i am anxious to see what kinda mods you come up with.

 

Doubtful... because 3.5 is a monster 0-60 time, he must be running out of juice up high. Like BIGTIME out of juice. Even with AWD, that seems like a really weird launch where you would pass everyone up front and then get caught at the end...

 

Actually 3.5 is optimistic but certainly possible. A well tuned K04 S4 on 100 octane should pull mid - high 3's. Keep in mind, this is AWD with 450 - 500 lb/ft coming in at about 3000 - 4000 RPM and nearly the same in HP at about 6k revs. Certainly enough to get those times. At the end most will run high 11's to low 12's with a trap between 115 - 120 MPH. Obviously other cars running those times may trap a bit higher but I wouldn't say this is running out of steam.

 

Hello scalbert, nice to hear from you again

A guy I know in Toms River (not too far from me, known by Mike2KS4 on the audiworld forums) was very able to pull high 3sec 0-60 times on Stage 2+ (chip, downpipes, exhaust) with an RS4 clutch, stock K03 turbos, pump gas. With this setup, numbaonestunna, your absolutely right. The car runs out of steam ALOT on stock turbos. it has great low end, but with the K03's being smaller than even a stock DSM 14b turbo, they just cant flow enough at chipped boost levels to feed the 5 valve 2.7L V6 high end. On GIAC K03 software I was spiking 18lbs but tapering to 14lbs at redline.

However, with times like 12.1 at 117, this most certainly suggests the car was on the upgraded K04 turbos. In which case, they flow plenty to feed top end. The car will make massive power straight to redline with good software. K04 cars will hold about 20lbs straight to redline, not to mention with cooler, more efficient flow to the cylinders. 12.1 on pump with K04's is very common. Running out of "steam" is not a problem

 

I guess what I'm saying is that normally with something like a 3.5s 0-60, you would have a much faster quarter mile if you'r not running out of juice. I'm not disputing the Audi's power or ability to make 3.5s 0-60 (although it seems a *bit* optimistic, upper 3's is a HELL OF A LOT DIFFERENT than 3.5)... more like if you had a 3.5 second 0-60 I would think that you were running out of juice up top, only your mph doesn't really show that.

1/4 mph 118.43

I put new Nitto drags ons and still got wheel hop in first and a lil in 2nd lowred to 17psi. Guess Ill get some ET streets for the track!

Best 1/8 et 7.99
best 1/8 mph 93 mph
best 1/4 mph 118
best 1/4 et 12.1

-------------------------------------------------------------------------------------

That cobra is running a rather pathetic 2.0s 60 ft, which the Audi should decimate. However, look at the final run... 12.1@118, which is just about what the Audi had. That means that if you ran the Audi against this Cobra, the Audi would BIGTIME jump off the line, but then what happens? The audi ends up running the same final MPH, so does that mean the Cobra caught up in the middle?

My point is, that seems like a weird mph (too high for 12.1 with a monstrous low end launch like that, or the ET is too high... something doesn't add up.) Does this make sense?

Any comments? I'm curious to hear what's going on.

p.s. -- edited to try to make this stuff more clear.

 

You have to remember what contributes to such a fast 0-60 in the audi though. Number one, all wheel drive. Grips like a bastard. Impossible to spin unless you have the shittiest tires in the world. Number two, the 2.7L twin turbo was designed for massive low end torque. Stock, the motor makes 258 ft\lbs of torque at 1850 rpm. Extremely early. The K03's are so small, they are at full spool almost off idle (stock boost is 8psi). Chipped, it doesnt take all that much longer. Especially after downpipes and exhaust, spool is nearly instantaneous. With chip, downpipes, exhaust, your talking roughly 330 WHEEL torque before 3K rpm. Thats alot of off the line power.

Like I said, the K03 turbos were designed small and built for strong low end and midrange. They run out of steam for the 2.7L on its high end, but again, they were designed for 8psi. Which is why so many go Stage 3 with the car for the bigger, better breathing K04's. You will notice a big jump in low and midrange power with the K04's but not as much as you'll notice in the top end. it makes lots of power straight to 7K redline instead of dropping off around 5500-6K. With these, you will notice a faster 0-60 time but not that much faster. The quick gearing of 1st in the 6spd only lets you see about 14psi in first, no matter what turbos your on. Then by the time you hit 2nd, your very close to 60. So 3.5sec is fast, but doable in the S4, especially with things like weight reduction. The 0-60 doesnt change a whole lot though with the bigger turbos just because of how short the gearing is. 3rd and 4th gear pulls however .. you will haul ass.

I'll try to decipher this, but its very difficult. Your comparing two very different cars. A RWD, supercharged V8, lighter mustang to an AWD, heavy, 5 valve twin turbo 2.7L V6. Not to mention the coefficient of drag of the two cars. I'm not sure about the Mustang but I know the S4 has a .29 .. which is very low. Its actually the same as a C5 corvette.

Almost certainly, the mustang should be running a MUCH faster 60ft time especially with slicks. All S4's, stock or modded, really wont see much faster than a 1.70 60ft. Right off the lot they are capable of that, and modded thats still about the best they are capable of. Mainly because of the weight. They weigh in at about 3700lbs. Correct me if I'm wrong (my mustang knowledge is limited) but I'm pretty sure the Cobra weighs less. Not to mention it has much less drivetrain loss. AWD is great for launches, but after the launch, its almost a nuisance. Your using the motor to power four axles instead of two. The torque has to be transmitted through the trans, front differential, Torsen center differential, and rear differential. Not to mention all the added weight of the AWD after your ripping down the track.

If you look at trap speeds of Evo's, WRX's, STI's and such, you'll notice even with fast times they will trap slightly lower. My friends WRX runs a 13.5 at 99mph. I went 13.4@103.5. One of the reasons the S4 will trap more like a RWD car is the 5valve technology, DOHC and variable valve timing. It moves air quickly and makes the cylinders work very efficiently.

ET is more a show of driver skill than power. Trap speed is really a show of horsepower, but isnt good for comparing different cars together because of differences like weight, gearing, drivetrain config, etc. It doesnt seem to me like the guy in the mustang could drive. It also seems to me something is wrong with his car. The site says 490RWHP and 490 RWTQ. I could be way off but I think a RWD car with that much power should be trapping higher than 118. and definately faster than 2.0 60ft, and 12.1 trap. Mike's 2000 S4 with hybrid K04\K16's went 12.2 at 120 with less than 400 wheel horsepower, and a 4 wheel burnout off the line.

Also, I dont know if this is true for all cars, but it is true for the S4. The faster your 60ft time, the lower your trap speed. Slower launch, faster trap.

As to your question about the cobra catching up in the middle, your forgetting to take into account the differences of the two cars. AWD vs RWD, 6spd gearing, drag coefficient, weight. Off the line, the audi will take the Mustang (especially with that guy driving-lol). But once they get going, the AWD and extra weight becomes a disadvantage. The RWD mustang then has the weight and drivetrain advantage which is why it seems it catches up. I would assume if he could drive better the gap would've been closed even more. Theres no reason a 490RWHP mustang couldnt catch a plane jane K04 upgraded S4. most mildly modded K04 S4's will go 12.0-12.3, with more heavily modded ones going 11.7's even. Heavy weight reductions will show mid to low 11's and massively modified S4's have seen 10's. The Garrett turbo kits have just come out for the S4 (offering twin GT25's, GT28's and GT28RS's) so the rules may have to be rewritten on those times. The garretts are much more efficient than the K series turbos and I have a feeling we're going to see ALOT faster daily driven S4's. Watch out for these cars, they will be absolute monsters.

Hope I helped, let me know what you think.
