OK so here it is, I have my car a 2001 c5 coupe, cam, longtubes, high flow cats, h pipe, ghls, underdrive pulleys, dynoing 375 at the wheels, and I am on my local "track" tonight, closed course, no other people around, and I'm running next to a 2005 Audi S4. We hit the striaght away at about 70 and pull from there. Me, I'm thinking I'm going to pull this car no problem, reality is, I beat him, but not with nearly the ease I thought it would be. Lets put it this way, I beat a 2005 c6 6 speed way worse than I beat this S4!! That car was down right impressive!! But I have two questions, one being I was running without my top and we hit speeds of up to 140, what kind of acceleration am I losing from that, and two, when my car was tuned it was tuned with everything listed above except the GHL's, at the time it had the stock mufflers, can that screw up the tune? I was very disapointed in having this sport sedan running so well next to me, this will probably be the thing that tips the scales and makes me go blown!! Does anyone have any imput?? My only thought is that he had some work done to his car, if not, I'm ordering the supercharger!! Thanks for any help with my dilema!! Have a good night!! Thanks, Dan

 

Well just order a ATI supercharger or the new rear mounted turbo setups and you will spank his a$$ bad.... And u will keep the same drivablity as stock

 

Yeah I know I will spank him then, but I was real disapointed that I didn't smoosh him then!! I guess i win is a win, but I like to really win!! But I guess that's what the supercharger will be for!! Thanks for the input!! Dan

 

Well aparently he is not stock at all the specs on those are 0-60 in 5.2 sec so somthin is wrong here. Either your car is not running right or he is modded too? U sure he dont have a supercharger?

 

I agree, sure doesnt seem he was stock!

 

They do make a supercharger for the new S4 along with LTs, exhaust, cam etc etc. Theres a very good chance he has work done. With the power you have, you should have pummeled him bad.

 

I was thinking the same thing until it happened. I thought I would have pulled on that guy like he was sitting on jackstands. So that is what i was thinking, that he had work done. I know those cars are running 343 horses but it's heavier, it's all wheel drive so it's turning over more mechanicals, and it's almost a 100 hp less!! So, my conclusion is he must have had something done. I'll have to ask around and find out. I was really bummed about this last night but he must have soemthing done. Regardless, I'll be making phone calss about superchargers today, just for a little insurance!! Thanks for all the help, Dan

 

Get the supercharger, you won't be disapointed!!! However you'll always want more, 550 HP at the flywheel gets boring very quickly
That's why I'll be going with a 408 and F1R (or FFHP Turbo kit once its out). Then nothing will keep up with me
ECS is the way to go if you arelooking for a SC kit, their Paxton kit rocks as well as thei customer service, they are great guys to deal with. Give them a call (don't bother with the stock ATI kit, its not worth it)

 

Here is the specs for a Audi S4.


DOHC all-aluminum 90-degree 4.2 liter V8 with 5 valves per cylinder, variable valve timing and 2-stage intake manifold
Displacement: 4.2 liters (254 cu. in.)
Bore: 3.33 in.
Stroke: 3.65 in.
Compression ratio: 11.0:1
Horsepower (SAE net):
manual: 340 @ 7000 rpm
Tiptronic: 340 @ 6800 rpm
Torque: 302 lb-ft @ 3500 rpm


Performance


0-60 mph in seconds:
manual: 5.3
Tiptronic: 5.6
Top track speed: 155 mph*

They are pretty quick once they are rolling. I have A6 quattro twin turbo with 2.7 motor. Your guy has no slippage (100% traction). A lot of people are folled by how quick these Audi Sedan's are. He also could have after market software installed that freed up some more ponies.

There's a guy up in CT that tunes these Audi's, I plan on taking mine their when I get some spare time. For $1,500 bucks I can some software updates and turbo changes that will give me another 60 HP and quicker turbo response.

Don't count on it! There is always someone lurking out there to smoke your a$$

 

Hello Dan,

there must be something wrong with your car. The Audi S4 V8 (8E & 8H) is not a fast car at all. In fact even a stock C5 A4 shouldn’t have a problem beating this Audi on a dry track. This is due to the enormous weight-advantage as well as additional drivetrain-loss the Audi Quattro has. However, this 4x4 helps the Audi a lot accelerating from a dead stop – but beyond 30mph, this car simply sucks.

Tested by a German magazine:

Audi S4 6-Speed - Auto, Motor & Sport - Jan 2003
0-100km/h (62mph) 5,7s
0-160km/h (100mph) 13,2s
0-200km/h (125mph) 21,0s

Chevrolet Corvette A4 Con – Auto, Test & Tuning – June 2002
0-100km/h 5,6s
0-160km/h 12,0s
0-200km/h 18,4s

Greetings from Germany,
Johannes

P.S.: The brand new RS4 on the other hand is a totally different beast:

Audi RS4 - Autobild Sport Cars - May 2006
0-100km/h 4,6s
0-160km/h 10,0s
0-200km/h 15,4s

 

[QUOTE=gorillavet]Hehehe, that would be true If I was in the USA, unfortunatly I live in France , the good thing is that once you have over 500 at the wheels you can destroy anything on the road, don't even try to find a competitor when you have 800+ RWHP like I plan to. People here don't mod cars

 

Driving with the top off is like driving with an open parachute.

Think I am exagerrating? Find a buddy with similarly performing car. Race him with and without the top off. You'll be completely surprised. And here's the kicker : It not only has an affect at top speed, but at low speed as well. As low as 30mph, the drag really starts being noticeable. Even having the windows down makes a difference.

I had the exact same experience against a 5.0 litre Mustang.

And driving at high speed with the top off is dangerous in my opinion. I just don't do it. Car starts feeling squirly.

 

I have to think something is wrong on the vette, even assuming that S4 is modified you should have wasted him on the top end. With the Quattro and weight he should be significantly slower on top end runs.

The post below is from a good friend (former C3 owner no-less), not from myself. He is watching this thread however, so don't pull any punches! Enjoy!

Why don't you write back and tell him that an Audi man read his post and would like to remind him that this corvette hot rod barely beat what was no doubt a stock 2006 S4 - there is no 2005 S4 and there is very little aftermarket for the V8 S4's yet. (If is was an earlier S4, like mine, he nearly got beat by a 2.8 liter V6!)

Also remind him that this guy could have picked his family up from church afterward and taken them out to lunch and that is pretty strong comment when you think about it. Also remind him that the Audi no doubt out weighed his car by hundreds of pounds and would saved his life in a high speed accident is excess of 140 whereas there wouldn't be an open coffin at the funeral if you wrecked a plastic sports car at those speeds. That makes the car safe, practical, brutally fast and agile, and built to higher standards than GM could ever hope to design much less actually build.

Take your chick gitter home to mama.

Well, here in Germany the Audi S4 V8 (8E) was introduced in May 2003. The 420bhp RS4 finally hit the road in October 2005.

A friend of mine has a 6-Speed 2004 Audi S4 Avant (8E, 344bhp) and my Stock 2002 A4 Coupe was significantly faster. Especially beyond the 60mph mark the C5 just walks away.

Bottom-line: The Mercedes W203 C55, the BMW E46 M3 and many other cars are a lot faster than this particular Audi S4. It is not that fast at all. In fact: Some people say it is barley faster than the old Audi S4 2.7TT (8D, 265bhp) – as long as this car is unmodified.
So I highly doubt that this Audi S4 has been a stock V8 – couldn’t it have been a RS4 or an modified S4 (some Tuners (i.e. MTM) do put the 2.7 V6 TT Engine from the 8D in the 8E here in Germany!)

 

There is one around my town and i think i am gonna go pick on him and see how fast they really are. Dont think he will have a chance against my 10 sec C5 but just too see since this forum is liek turning into the ricer forum or the viper forum. You get a ricearoni guy saying the audi ect. is better. ect. Like the post above.. The only fast sedan is the mersedes twin turbo sedan.. Its a 11 sec ride but were talking about 100K+ for it... So funny how people try to compare stuff. Oh GM makes cheap cars. Well there hot rods not luxury granny cars. Like comparing a Hemi Cuda to a ferarri...

 

I would say that there might be something wrong with my car except my buddy has a stock c6 6 speed, and at the track, we did a rolling start say 50 to 100 and I pulled him a good 3 car lengths in that short distance. I know the stats on the S4 and I know they run well, but I would have thought I would have burried him, I was just very surprised and was wondering if it was the top off that really made a huge difference as the above post states it could be. I'm going to have to do a little research and see if I can find out a little bit about his car and see if there are any mods done. Thanks for all the info and support, and the one audist above, I will respond to your post when I have a bit more time, meanwhile sit there and enjoy your inflated car payment. Thanks, Dan

 

Look forward to seeing what sugarwolf does.

I know that those AUDIs can be hyped up and can run very quickly. I am not shocked to hear that you had a close run with one.

 

That is true for the old model with 2.7 V6 TT. This car was even sold by Audi with 380bhp here in Germany (with different turbo). They called this model RS4. This engine can easily modified by raising the boost.

However, please keep in mind that we are talking about the new S4 V8 - modifying this car is not easy at all!
