Went to lacal track here in NY.Temp was like 60' and Humidity was normal if any at all.
Car is 04 vert auto, 3:15's Z-51 and mods are-Borla stingers,granetelli intake,and we did the TB bypass and removed the screen in the MAF.The best I could get the car to run was 8.58 .best MPH was 86 and that was on a 8.68 run. 8.58 = approx 13.38 in the 1/4.Had it in 3rd w/ traction off and in comp mode left at about 1,600 rpm's.60ft times were consistant 2.0XX.no spinning either. I thought these cars were right around 13 from the plant?What would my car have run stock?13.70's?Just ranting a bit and wondering if this was normal.

Depending on conditions, 13.5-13.7 bone stock is about right. There are some who do better however. I have seen 2.73 geared C5s struggle to break 14.0 in warm weather.

BTW that 8.58 = approx 13.38 in the 1/4 is pretty good. I have seen in another table that 8.58= approx13.47 in the 1/4. However who knows unless you actually run the entire quarter.

A good friend of mine with a car exactly like yours, Commem edition A4 3.15 vert, '04, but stock except for a set of Eagle F1 Supercars on the rear, did 13.55, 13.8x and 13.75 just recently. Had it been on rear runflats, I doubt it would have hit the 13.55.

Its amazing how many people think that bone stock C5s routinely get into the 12s or even very low 13s with ease. If you are in Houston maybe, but rarely in the northeast. 13.5s bone stock are about average with some above and some below. 12s are a fluke.

13.3 is in 1/4 on a stock Vette is doing fine. Add some long tube headers with a decent tune and you'll be in the 12's.

Sounds about right.

Better weather will get you closer to low 13s

Ran 13.1 with 3:73 and Yank 2800

Ran 12.6@113 with headers, intake, ls1 edit and stingers added

90 degrees 83% humidity

Don't be knocking my 2.73's. I put a 13.4@106 down in 100 degree weather with 95+% humidity in July in Louisiana:P In cooler weather I ran a 13.1@107. Only mods are Borla Stingers(+what maybe 2hp?), Stinger Intake, and shift point only tuning with my predator. My fastest bone stock run was a 13.28@106. I dyno'd it last week at ThunderRacing and it only put down ~300ish hp and 307 torque.
I had a Yank TT2800 installed last week. Suprisingly even with 3.0 STR I can't spin the tires(on the street even!) with traction control off and dunlop sport 9000's. It definately gets my car out the hole much quicker.

It all just really depends....

I wouldnt say the car is slow.....

In my case my bone stock 2.73 has went 13.5 at 103 mph several times in 78-85 dgree weather....

Actualy I just did it again last night bone stock at 78 degree's.

If my car had your 3.15's I would hav ran a 13.4 last night bone stock...

If I had your 60 degree wather vrs my 80 degrees my car would pull a 13.3 (or possibly better) bone stock...

If I had your Gears + weather + mods I would surely be in the 12's....I beleave our car can be to but it takes some practice.....Even if your an experienced racer you still haveto learn what works for your specific car.

All the times you see of people claiming low 13's or 12's bone stock PROBALY didnt happen there first time out....

It may have taken them 100 trips down the quarter to get that best slip of 13.3 bone stock...

My first time out my best was a 13.9......Nonthing changed on the car or the weather and I now run 13.5 due to practice.
So dont think that your car is slow.....

CaR and driver got a 13.0 out of a bone stock MN6 Convertable...

You think they couldnt gt a similar time out of the a4 w 3.15..

At a minimum of 13.2 Id guess is what they can get ( many people beleave the 3.15 a4 is quicker than the MN6)....

So what im tring to say is that yea it's possible that you got a slow one from the factory BUT it's more than likely that you just need some more practice...

There are two many people on this board that have ran 13.3 or better BONE STOCK for you too say these cas are slow.

laron

just took a lok at you mods.....

The exhaust is only good for a tenth tops.....

The intake is also only good for a tenth.....

Removing the screenis very contraversal on any vehicle...

Sure you allow more airflow.....But ten the air isnt as smooth and even apon entry ( the vanes in the screen straighten the airflow...) so well just say this netted you nonthing in et....( But it those help throtte response)

So your only looking at about being two tenths better thn stock...

So you would have crept a 13.5 bone stock...

Not great fora 3.15 auto in good conditions...But not bad eighter...

I promise that if you go try a few more times you'll atleast drop another tenth....

Then that would put your stock time at 13.4 (about right) and your lightly modded time at 13.2....Also about right....

GOOD LUCK!!!!!!!

LSK

My car did 13.68 bone stock so you are right on track.

shurite44

I owned two 03 A4 vettes with 3.15s. Stock 13.7 is about right. Install a Vararam and tune with a hypertech III and you will be in the high 12s, I know I did it. Nothing to do with skill all I do is hit the gas no powerbraking, I run faster that way.

laron

STOCK FOR A 3.15 IS AROUND 13.7!!!!!!!!!!!!!!!!

NO NO NO NO...........I cant beleave that....The times for the norm just keep getting worse and worse...

SO I GUESS 2.73'S SHOULD RUN 13.8 STOCK???????

Seriously...... How many times did you take your cars to the track before you modded???

13.7 is what maybe a 97 a4 with 2.73's before the LS6 intake manifold might do at a best bone stock.....And even people with pre LS6 intake manifolds in bone stock 2.73's have done better than that....

Im very confident that a good driver in good conditions can get a 13.4 out of the aveage 3.15 a4......

It might not be your first pass or even your 40 th pass but it can be done......

If my car could only do a 13.7 at best in 60 degree weather I would go do a dyno and try to find the problem....

If she dyno's between 285 and 305 then you know your a4 is within the norm and the problem is the driving or not allowing enough kool down.....Too much gas........To much/little tire pressure........Crappy launch technique..........Bad track prep.......

Somthing has to be wrong........

Please dont take hat Im saying as directed to anybody in particular...

Im just flaming because Ive read a lot of these my car only run 13.9 or 13.7 post....Or my cars slow post.......


YES..... One out of every so many cars is gonna be a factory lemon and only dyno around 279 while everyone else inthere stock a4's is around 289 to 299 on average....

Some engines are for what ever reason weaker than others.....

But These cars are not high 13 second cars on average...

The average C5 weather a4 or mn6 can run a 13.5 or better.....

Te normal range is from 12.9 (outstanding) to a 13.6 ( in some a4's with 2.73's) 13.6 is usually the normal (worse ) that you read about....

I realy hope that you go back to the track a few more times....

I mean your not doing bad right now with a stock 13.5 and slightly modded 13.3 but you can defiently improve.....

LSK

I took my car to the track once and there was no traction when I ran 13.68@104 - 2.2 60 foot.

Then I did the ziptie mod and the Z06 mufflers and went to a different track and did 13.29@105 2.0 60 foot.

My next mod is an LS6 intake and that should get me into the 12.7s with practice.

So basically a few boltons will gain me a second.

LSK

My 13.68 was on a bad track - 2.2 60fts. No need to go overkill and dyno the car. Part of drag racing is the 60 foot. It is a big factor in ET.

shurite44

I would not worry about a 13.68 on a total stock C5. This is average, a 13.5 is an exceptional run at 60 degrees with a stock C5. The only good a dyno would do is if you let them tune it, then you can expect about 3 tenths but remember it is no longer stock, the PCM has been modified. Stock C5s run in the mid 13s and stock Z06s run mid 12s on a standard day. I know we see posts that contradict this but I also have seen these guys get busted for posting false time slips so I am a non believer of some of these times. Some people do little mods like the zip tie mod and still consider their car stock but they are wrong, it is moded at this point and the zip tie will get you a couple of tenths, just like you said you did a zip tie and I believe you said some cat backs and you droped 4 tenths. When I first started moding I got it the high 12s with a hypertech and vararam vr1b cold air intake, total investment about 7 hundred bucks but I was no longer stock. The first second of your stock ET comes easy and cheap, but every tenth after that you are paying big bucks for.

shurite44

I agree a stock C5 can run a 13.3-13.5 this is not in anyway out of the question. Is it the average no. The average run is 13.5 plus. I run a little slow for a reason I see very few people touch on in here. I am a fat guy. I weigh 266, sometimes my cousin runs my car which is moded he weighs 170, his best time in my car was 12.71 and on the same night my time was 12.81. So it is only a tenth but I gota tell ya I wish I had the dicipline to lose 80 lbs it would save me 5 hundred to a thousand bucks in mods. I occansionally would squeak out a little better than a 13.7 in my stock vettes but the average was around 13.7. I believe my best time was a 13.62 or somewhere around there. I know I never went below 13.62 but with a normal size guy it would have run a 13.5. But I see posts for 12.81 bone stock at 75 degrees or so and I just do not buy that. What impresses me about the vette is the consistancy of the ETs. I can run withing 3 hundreths of a second of my dial in all night long, and I have won money at the super chevy show and trophies with this very effective bracket racing supercar.

I am saving for my Yank 2800 hope to have it by mid season next year. question how much was the installation on the yank for my planning purposes

I agree, practice is all you need. I bet you can get low 13's with enough practice and under the right conditions. My bone stock 97 went 13.000 with runflats(3.15 gears), the weather was cool and there was very little humidity. I have been dragging at that track for the last 6 years so that could have helped me out some. Good luck! Hope to hear some good numbers out of you car soon.

If your running an A4 with a basically stock set up.... the times you are running are right on. What most people don't get is... Low-Mid 13's is a fast car (stock).

I'm not sure why some people think a person is going to reduce half a second with practice ?? What's that all about ?? Take your average stock (or slightly modified) A4, trans in 3rd... Turn off the A/C and traction control... Pull up to the lights and stage... One foot on the brake, one on the gas.. bring the RPM's up to about 1,200... Last yellow go to 'all throttle' and off the brakes... Then hold it to the floor till the end.

I don't see how anyone can gain half a second by practicing. There's not really anything to do. At stock power levels, you aren't going to end up with any real tire spin to try and control. Your timer doesn't start till you car moves forward... The light could turn green, you could sit there for 5 seconds, take off and you will have a 13.5 (or what ever).

The main thing is... HAVE FUN

FAST cost $$$..How fast do you want to go?rolleyes:
