Best BONE STOCK LT1 A4 E.T.s......

the title speaks for itself. just wondering if anybody out there faster than when i had my car stock....




jon






NOTE: "stock" reffers to absolutley NO mods. no K&N, no muffler, no removed jack/spare, nothing gutted or removed, etc.:D

My 97 WS6 3.23 auto ran 13.87 when stock.

The night i bought my car (it was used) i went to the track.
First pass was 13.94,then after experimenting i managed a 13.82 and a friend that is about 70 lbs lighter than me went 13.78.

13.98 in the middle of the summer here. I didn't wait around long before I started modding it, though. :D

Time in sig is with full interior, and no mods.

i went 13.97@99.8 w/a 2.1 60ft w/ 80K miles w/ a paper air filter. :)

OoPs.. A4's sorry...

Dead stock on factory radials my full weight TA convertible went 14.08@99 mph .

Ok, fine i have now heard of 1 LT1 a4 vert that stock to stock is quicker than mine...Today is a bad day :(

Well my 1994 vert went 14.3@95 last summer. Hoping to improve on it over the summer.

My 94 Z convertable went 13.98 @ 99mph totaly stock with 3:23 gears. I was told that was pretty impressive for it being "stock"

14.08@99.16

pretty impressive times guys! wow, there are alot of convt. on here:D

BUT....still nobody as quick, or quicker, than me yet.:)




jon

Yes, but remember elevation, weather conditions and track prep is a very missed piece of the pie...if someone ran a 14.1@98 MPH @ 3200'....

You never said what you ran in th 1/4.

best ET was a 13.62 @ 102.17 1/4 8.83 @ 81.34 1/8 with a 2.03 60ft. this was two weeks after i bought my car with 83k miles. only options it didnt have were t-tops, CD, and leather. car was equiped with 2.73s and weighed in at 3640 with me in it.

i still havent heard of a similar A4 going that fast to this day.....




jon

Not to be a *****, but the car had 83K on it so do you really know if it is "bone" stock...easy to hide things...put a hpp on it...little things that add up.

Yeah that's really fast for a stock A4... I dunno about that one :think:

thats ok. its not the first time its been questioned.

first off, i bought it from a repuatable dealer that specialized in performance cars. they had many modded cars as well as some stock cars. believe me, if it had even had a CAI, they wouldve told me.

second, i know more than a fair amount about cars, and if their had been anything on the car, there would have been some flags that would have gone up. the car was BONE stock. i also had a friend that works at a GM dealership check it out after i bought it. we looked the car over top to bottom, nothing.

just out of curiousity, what things are "easy to hide" from somone who knows at least anything at all about cars?? think about it before you shoot off an answer.....

the last thing id like to say is this- i hit that # ONE TIME. ive run several .7s-.8s since then, but i havent seen that time again. i ran my fair share of 14.0s before i figured out about how our cars dont run worth crap when their even remotely warm. with a new set of bridgestone radials, and a almost perfect day, i ran that # once. i made several runs thereafter to try and back it up and came away with two 13.7s both at 101 right after the 13.6 pass. the last pass was a 13.8 at 100. like i said, it was an almost perfect day.


only thing i can figure is....FREAK.:D

I heavily believe that there's no such thing as a factory freak.

you can believe all you want but when youre mass producing ANYTHING, theres bound to be a few that are a little different. ;)

and that can be in a good OR bad way.



freak or not, the ET is for real:)

Hehe, you never saw my car:) My car ran a best of 13.01@105mph with a 1.82 60 ft. I had the following mods: cold air, MSD 6A, Taylor wires and NGK plugs,home made boxed stock LCA's, Nitto DR's, Borla y-pipe and cat-back, Meziere waterpump and ported MAF. I had no headers, stock 3.23 gears, rusty stock driveshaft and the stock trans(which actually slipped on that run) with over 100k miles. No other mods. The car just ran faster than it should have, what can I say:)

I went 13.72@103.14 mph with 1.99 60Ft on GoodYearEagles in my 93Z back 1996. I got lucky with a good hook. Every pass after that was 13.8's-13.9's The car had 40,000 miles on it and one owner and never saw any track time...til I bought it :)

Let's see, have you completely torn the motor down? Lets try, rockers, can't tell unless you remove the valve covers, gutted cat, unless you looked through it too. There are also some things like ported heads, a stroked crank, an overbore, etc. A stall convertor is another one, but a bit less likely to miss. If the motor is a rebuild, how would you know? a 355 with good compression could run that. A stroker with stock heads could and you would never know, because all you would be getting would be a bit more torque, not a ton of hp. Heck, there is a guy on the board here that just put a cam in a car, no headers, etc. and it made 318 RWHP, and it idles like stock. When I put my junkyard motor in my car, I figured it would be a dog. It ran 13.8 @ 101 with a 3800 lb raceweight. No freemods, unless you count the gutted cat, which was done after it clogged up. I felt it might have had something done to it, but nope. I tore the motor down and it IS stock. It also had 183K miles when I put the motor in the car.

ok, rocker arms you say? yes, i have taken the VCs off and im getting ready to put 1.6s on now. gutted cat? i just gutted them myself not more than 3 weeks ago. ported heads? a friend of mine that has been working at GM for 4yrs+ helped me put an intake gasket on about a month ago. he said it looked like the first time it had been done. so, that eliminates head work, bore, rebuild, 355, stroker, etc. stall? give me a break. cam?? ive heard many a cammed cars, there IS going to be a difference in sound even with the smallest cam over stock.

also, as i said before, look at where i bought it. if it had had anything like the aforementioned, (355, stroker, cam, etc) they would have used it as a selling point and deffinatly told me about it. people who go there to buy are either looking for a stock sports car, or a modded one. its that simple.

you dont need to tear the motor down completely if you know what your looking for.;)



jon

So, you are saying your GM mechanic took the heads off to do the intake gasket? Not too sure why. Anywho, maybe the previous owner bent a valve and had new valves and a valve job done. The consensus here is that a decent valve job will net similar to LT4 head flow numbers. That could give you a bit more power and the numbers you got. I am still wondering though, why would he take the heads off and measure the bore to do an intake leak. I'm not saying you are lying, just pointing out he went to extreme measures for no reason apparently. As for "knowing what a cammed car sounds like", I hope you never race this "stock" car then.

re-read what i said. we did an intake gasket. he said it looked like the first time it had been done. ok, some common sense here. IF IT indeed was the first time the gasket had been changed, then how would one go about porting the heads, boring the block, putting a bigger crank in, etc. without ever taking the intake off?

albiet, you COULD do a cam w/o taking the intake off, BUT of the cammed LT1s AND LS1s ive seen, there was no question to whether or not the car had a aftermaket cam.




jon

I dont know how everyone is getting all these low 14's, Heres what mine did

1995 Z28 A4 73,000 miles on the clock

14.617 @ 95.23 mph w/ 2.321 60'
and i have a flowmaster muffler w/ tips on it so not completely stock :(

I just wanna go faster...haha

Any chance i'm just not launching right, its an automatic, so when i'm goin, i'm basically just holdin down on the juice right through 6,000 rpm's till she shifts. I've also pulled of 97 mph but still not better times than the 14.617

I believe what you say with your car running those times. Anything can happen at the track with the right conditions. A few other things to consider though. Tuning for example could be done and regardless of your vehicle knowledge you could be none the wiser. Like someone else mentioned someone could have hooked up a hppIII to it long before you came along. Now we all know it's debated left and right wether they actually help you or not. But the subtle changes it possibly made could prove the .2 tenths of a difference. Heck Madwolf guarantee's 13rwhp with his tune on a bone stock car. Something like that could have been done and nothing would seem different. 13rwhp should easily be able to net that et. Again I'm not saying your lying at all, I believe you. Just consider the possibilities something like that is in the mix.

Took the 95Z28 to the track this past friday night. Ran a best of 14.21 @98mph. Had a best 60' of 1.97 and reaction time of .494 with .500 being perfect for the track specs. The track is at 1300ft above sea lvl. so the corrected et is 14.01. The car is bone stock except for a 10 bolt 4.10 posi rear, poly bushings, KYB adjustable struts and K&N CAI. It has a T56 6 speed with pro 5.0 shifter and borg warner centerforce clutch. Couldnt get tires to hook too often and burnouts were hard with the manual tranny. This was my kids first time racing (he's 18). It was very hot, humid and somewhat windy. Tried as we might to break into the 13's but just couldnt do it. His reaction time on the 14.21 was 1.112. If the tires had hooked better we could have made it. I thought the low 14 time was great considering he has no experience racing or much experience with a 6 speed either. It was a fun night and we plan on adding headers soon and going back for more.

i am not trying ot be a smartass, but have u looked to se if it has an lt4km? that would be an easy one to look over and not notice :cool:

Man, someone brought this thread back from the DEAD. Over a year and half ago I posted this, wow.

Well the car is long gone now but I still stand by what I ran. I learned a lot while owning that car added to what knowledge I already had. I've since worked at a GM dealership as a mechanic and also at a machine shop rebuilding motors. The motor on that car had never been touched. There were numerous tell tale signs which lead me to that conclusion. As for the computor programming, that was a possibilty, but highly unlikely. Reason- The car was sprayed for ayear and a half with the stock plugs/tuning/etc. As you know, a HPP or the like increases timing/spark, which would have definately shown through with the nitrous.


The car ran good and since I posted this over a year ago, I have seen other LT1s locally go as fast/faster than mine. Seen 1-2 A4s run 13.5s stone stock and a few M6 cars run 13-3.-.4 without anything done.




Jon

damn i ran 14.5 at 95 stock as can be! but i am finding out slowly that i had clogged fuel filter bad air filter and plugs and wire needs replaced! i am halfway through fixing all this and i am at 14.1 at 99 now! and i nthe middle of summer heat

Man, this is an old thread.

Anywho - Sounds like the conditions at your track are pretty damn good. I assure you, you wouldn't run those numbers out here in the AZ heat. You would have been doing good to see a 13.xx in the best conditions here )3000' DA or so). Either way, you ran the numbers...just don't think you have a freak because conditions will make or break your times. :)

I would like to see some updated times in this thread especially for verts with 2.73 gears like mine.Also times are fairly meaningless without knowing the 60fts,altitude of track is useful as are things like temp,bar..all the things called density air.And tire type is very important too.Stock car on nittos is different from stock car on street tires.

I ran bests of 14.96 at 95 mph this year with my vert.And it had g2 air induction,holley powershot,airfoil,1le bellows,tb bypass,160 stat,hpp for fans tuning out,gms maf.I was only able to get 2.38 and higher 60fts though on the crappy track on street tires.Track is at 1700 feet.It was very humid that day around 80 degrees.Buddies 94z with cold air,airfoil,1le bellows and flowmaster catback and ypipe and 3.23 best was a 14.5 something at like 98 to 99.On street tires with also around 2.40 60ft.He has hit 13s at same track on drag tires.Even the ls1 cars are hard pressed to get 13s at our track.No track prep..without drag type tires its very hard to get good times.

Just for clarification, in case you didn't read the whole thread, here was the down low- '96 Z28 A4 2.73s HT (Hard Top) 81k miles, no leather, power everything, bone stock from the muffler down to the air filter, didn't remove spare tire/jack, eng temp was 160* on the run, outside temp was about 70*, humidity was prolly 10-20% (not much), left off idle, ran on 245/50-16 Bridgstone Potenzas (Radial street tires) =

2.0 60ft, 8.8 @ 81 1/8th, 13.62 @ 102 1/4.




Jon

I for one am glad that this topic showed back up. I took my stock 95 Z28 to the track on Friday night. I'll have to wait til I go to lunch to get my timeslips, but I know that the car is very sensitive to engine temp. The cooler the better. On the best pass of the night I was showing about 140-150 on the temp gauge and it had sat with the hood up for probably 45 minutes or so.

Here was my best pass.

R/T .051
60' 2.213
330' 6.106
1/8 9.273
MPH 77.890
1000' 12.004
E.T 14.329
MPH 96.55

I don't think it is too bad for a stock 170,000 95 Z28.

Best time when my car was stock, or what i believe was internally stock, was a 13.68. Never saw the time again stock, but also have not run since any mods. This was done on DR's with 158,000 miles.

About the best i got with mine was mid 14's. Haha way slower than 13.6. Oh well. I wish i could crack a 2.0 '60 time though i think i could get about a 13.7x then. Or i could just get some DR's.

TONY

Some of those stock LT1 times are crazy! 13.3 13.4 :eek: Lot's of M6's around here get high 13's and low 14's

jees,from the responces one would think this was the BS section

Although some of the times may seem unbelieveable, they are entirely possible. There are a wide range of times that a stock LT1 can run, depending on track conditions, reaction times, and launch traction.

I agree totally. The elevation of our track is about 2100 feet. There was very little wind the night I ran. I felt like the humidity was a bit high too, but it wasn't that bad. I am not sure how much better my car can run. I think it might be possible to get it to run in the 14.10's, but I am not positive.

my buddies 95 z vert went 13.6 @ 100 bone stock with a 1.82 60 ft. he works at a dealership and the lady that bought the car new traded it in and he picked it up.

my ss went 13.9 @101 bone stock with sheety 60 ft times.

My 94 ran a 13.64 @ 100.4 with a 1.95 60'. It backed that up with a 13.67.

Piloted a friends 1994 Z28 A4 3.23 to a 13.99 @ 99 :D

Leather, t-tops, power everything, lots of gas, big bag of college books and clothes in the car. Video's on my website.

It isn't bone stock, but I'll be able to give you an idea of what an optimum-running A4 can do w/headers/catback, CAI and a 2400 stall within a couple weeks. On street tires at that. :)

...this is an old, old thread. :eek:
