s4 (bi-turbo) vs. c43
 

stock on stock, who will win stoplight to stoplight? also in the freeway..just wondering coz i saw one a while ago cruising 680

You on the fwy, the S4 from the dig.

what are they rated at? 2.7 twin turbo... 280hp? is that right? well in any case im not sure i think that s4 was rated 6.0s 0-60 and im assuming with the difference in hp the c43 MAY stay ahead at higher speeds. someone plz correct me if ive got my numbers mixed up.

265bhp iirc. AWD and hit 0-60 in 5.7 again iirc. As for tuning, that 2.7t is ridic.

The S4 will dominate the C43 off the line. It was quicker to 60 by at least half a second. By the quarter mile, the C43 is getting pretty close. At highway speeds, the C43 is quicker.

250 bhp from a 2.7 L twin turbo V-6

well, no one really races 0-60 but for for sure most of us will race 1/4 mi most especially the freeway

1/4 Mile Times:

C43 14.6 @ 99 mph
E36 M3 14.6 @ 95 mph
B5 S4 14.2 @ 98 mph
Viggen 15.0 @ 95 mph

0-130 mph:

C43 29.2 sec
E36 M3 33.2 sec
B5 S4 29.9 sec
Viggen 36.8 sec

S4 is a beast. I've owned a C43 as you guys know, and my friend just got a B5 S4. S4 is quicker in my opinion and much smoother. Better watch out though Rico because if that S4 even has a chip you're done. Of course I'm talking about a 6 speed S4. Tip is a whole different story.

i never really race my car, i was just wondering. also, i if they're modded and i lost, i don't consider that a loss coz mine is stock.
how's it goin jared? have you seen the exhaust vid i made?

why do people toss in that clause all the time "well take a modded xx and its a diff story" well what about those same mods to the c43... what is wrong with you people.

however, chipping a turbo car gets you in the ranks of 40hp sometimes. i know large gains like 50 are bestowed to big turbo motors, like the 65 amg line.

i digress, were talking stock. i know c43's can be tuned pretty well, not cheaply but well none the less...

Well, simply because a chip on an S4 is close to $500 and gives you 70-80hp and 80-90ft/lbs of torque. To get that on a C43 you'll need to spend a few grand. In other words its very common for most S4's to be chipped right off the bat and not stock.

Rico, I've been doing good man. How's everything on your end? I haven't seen the video, link me, I'd love to see it.

Well, I have driven a C43 for an extended period of time and I personally own a B5 S4 I can give an honest opinion. The C43 Feels like a monster through out the revband and does have quite good acceleration its major downfall is its auto 5speed trany. The Audi on the other hand ::6speed:: gives the driver way more control to where the power is being put. Now lets get in to detail about this.

C43 = 300 hp at the crank.
S4 = 250 hp at the crank.
C43 puts down 240rwhp.
S4 puts down 190awhp

So with 50 less wheel hp the audi is still quicker.

Tuning on the S4 is insane.
Giac Chip yields 60-70 Hp
Down pipes are 40hp
People have dyno'd in as much as 350 AWHP with just a chip, intake, and exhaust.

Now to get 150~160 wheel hp on a C43 you would need a blower.

Also the C43 is LIGHTER then the S4.
I believe the C43 weights in at 3300~3400
S4 weighs 3600~3700

well im pretty sure you can get the c43 up to ~370hp with intake, chip, headers, deleted resonators, x pipe, racing cats, and underdrive pulley. im especially fond of exhaust work on this motor because this 3 valve design implements the removal of one exhaust valve, hence some restriction, let it breathe and it brings the intended horsepower of that motor out. i have read that the installation of a ram-air setup changes the cars high-end behavior making it more agressive.

i test drove a s4 once (6spd) i really liked it. the dealer kept insisting that i attempt full acceleration with any two tires on grass. so i pulled over and put the passenger side tires on the grassy shoulder with the other two on pavement. i performed a drop at a minor 2k rpm (as to not offend the dealer) and the car took off without complaint. i was really impressed with the meticulous management of all that hp through the quattro drive system. if i had one of those i wouldnt have to borrow my gf's xterra every time i drove up to the mtns to go skiing.

I just cannot comprehend this. C43 has stronger engine, lighter body, and slower? What is this? "Miracle of Turbochargers"?

What is the model year range of S4?

jared, dunno how to post a link but you can find it in the first page of the performance section.
good to hear everythings fine with you..i just started to look for work coz my papers just came in. you done at school?

2000 was their first model year i think, speaking of audi's, are they reliable?

Being an S4 owner too....its that the Quattro system just puts down the power more efficiently...IOW, no traction loss.

There aren't too many C4,B5 S4's out there that aren't even lightly modded.

I take my S4 when I'm looking for trouble.

FWIW, my S4 put down 298 whp/335 wtq on a Mustang dyno before my FMIC was installed.

dont go out looking for trouble. i was on i-20 here in atlanta today and got popped 112/55. i didnt get arrested but my lawyer said i should have been. he also said that some judges treat this more seriously than dui and could throw me in jail after my court hearing.... damn v8 got me in trouble!

Well, you also have to remember that the C43 is an N/A car. It requires some back pressure in the exhaust. If their is no back pressure HP is lost where as with a turbo car the opposite is true. the lest amount of back pressure is KEY.

So lets go over the list.
Intake maaaaaaybe 10hp
Exhaust ::headers, deleted res, xpipe, race cats:: AT BEST 20-25hp
Chip gives you 5hp but advances timing
pulleys give you no hp but they allow the motor to rev more freely.

Trust me I'm a Mercedes guy at heart, I did all those mods to my M104 Eclass to only gain 40 rwhp.
I did a
GruppeM C/F ram air intake
Fully custom exhaust.
Anti RASP resonator
Magnaflow Muffler
Custom hand written Stage2 ecu. ::7,000RPM redline, and a RACE file::
NGK plugs
Along with AMG high flow CATS.

My best Dyno was 220 RWHP and my other Dyno was 206 with a guy who didnt know about kickdown letting off at 6200RPMS.

Stock was around 180rwhp

I see the s4 has great hp potential. I really want the 04 e55 or the new c63 which I could afford. But having all that hp will get me into alot of trouble. Where these cars start opening up in the triple digits:eek:

I though you don't speed...... :rolleyes:

the Tips are actually really good. my brother has an 2000 S4 (tip) and he was able to beat a 335 conv - the only mod he has is a GIAC chip.

stock vs stock - it would probably be the S4 up to 60 and C43 would take over :X

The 2.7T is an awesome motor. I had an A6 before the benzo with the S4 motor in it and it was fun. I had GIAC ecu and it was a blast to drive. I know a couple people over at Wicked Motorsports in the valley that have made some VERY good numbers on that motor...
