well i have a 94z28 and got talked into going to a nearby track last night on a run what ya brung night. i was impressed. i got in about 6 runs with my best time of 14.011 @ 97.93. there was only about 4 lt1/ls1 camaros there and i only had a chance to reace one and beat him with my best time. it was awesome my very first race was against a 67 camaro ss. yup he won he had a time of 13.35 and mine was 14.22. my last race was against a built 73 camaro. he ran a 10.35 and me 14.078. anyhow i wanted to put this in here because i am still throbbing from adrenaline, awesome. although my car isnt comletely stock it is very close, catback and cai. i wanted to know what it would take to get into the 13's? could i just change my gears to lets say 3:73?
also when i got done and was driving home i noticed that my speedo was sticking. lets say i was stopped it would stick on 20, and when i accellerate it would jump let say from 20 to like 40. the only way i had a good odea of my speed was my tach. i am going to post this in another forum but thought i would mention it.

thanks

 

Hide your credit card. You're hooked and will be constantly spending money to go faster.

 

do you have any mods.? What trans. do you have? If you ran a 14 flat on a stock car, that is a very good time.

 

well i have a stock z with slp lmII catback and slp cai. i am pretty sure the rearend is 3.42, and a4. the car only has 16,000mi on it, so i do not want to touch the motor, but i would like to get the time well below 13, like around 13.2 or better. i do not know if it is possible. your right steve, all i have been looking at for the past couple days is headers, suspension, gears and a tune or programmer. i talked to a friend who works for mopar and he said i should be able to change the gears in the rear witout replacing the posi. i am going to look that up with him tomorrow. i am not sure about the dyno tune because the closest place around only does trucks, you know semis.

 

Gears are definitely a good choice as well as the headers. As for the suspension, do a search of previous threads as there are alot of components you can upgrade and several different directions you can go. But the best bang for the buck traction mod. which most will agree on is tires. As for the dynotune, I would say save that idea until you redo your motor w/ a heads/cam swap. Check out PCMS4Less or www.Madz28.com, both are mail-order tuners, they do awesome work and for great prices.

 

that was one thought that came to mind was to get some 15'' or 14'' rims with some drag radials and just have them one when at the strip. i guess i was looking at bolt on changes.

 

You have a 94 Z with only 16k miles on it?

 

Is it a standard? My 94 used to be a standard and the best combination of mods that I had for street/strip use that required no additional work or thought on my part were as follows:

Cold Air
Carb compliant headers
Cat back
Short throw shifter
Gears and LPE driveshaft (and loop)
Tune
Drag Radials

Daily driving still had good gas mileage (as good or better than stock), no idle problems, nothing internal to the engine, sound was great but not too loud, no problems with state inspections or emissions.

Once you go beyond that point you probably should start thinking about your goals for the car, but the above mods are easy to do and really enhance the vehicle. You should be in the low 13's at 101-102 at a sea level track or maybe a wee bit better depending on the driving...

 

Hey Ted how's it goin? My buddy has a '94 Z28 A4 3:42 gears and a 2600 stall. He's at least 100k on the stock block w/a p1sc supercharger and intercooler. He claims he's runnin 12.60@NED. I dont have the mph for you to compute but he claims he's runnin the 60ft time in 1.60 flat. But won't hand over the time slip. And i left somthing out on he's doing it on street tires; no slicks, or ET's or nitto's or BFG's nothing with the word MT. What is this kid in la la land or what! So my question here is my buddy wacked or what. You probably need more info? I don't believe him but, can you make sense of this?

 

Look at your shift area and if you have a 1 you have 3.23 and if you have a 2 only no 1st gear shown you have 2.73 gears. You said you have an auto. You might have 3.42 if someone installed them. You can mark the tires and do some math to figure out what you got.Or mabye go from what rpm you are turning at what speed.
Gears don't do all that much sometimes although my vert they seemed to be a reason that went from 15.0 to 14.3 with similar 60fts .I had 2.73 and went to 3.42 and added a catback and thats about it. Bam..lost 7 tenths .Not bad but our track is 1700 feet above sea level and my vert is like 3880 raceweight.Lighter buddy with 3.23 and flowmaster catback, iinduction and minor mods no headers or stall hits 13.8 with 2.02 or so 60fts.. not enough power to get under 2.0 60fts yet. Car dead hooks on his et street radials.

Anyway stall is great mod for a4 cars usually cutting 4 to 5 tenths off if you have the right tires. Tires are critical .nittos are not bad but et street radials or bfg drags or something like that are best if you are serious about times.

Headers for sure are good mod and necessary to get the low 13s I would think unless you are like near sea level. I would think stall and headers and tires will do the low 13s maybe high 12s depending on your location. I think buddy with 94z can hit around there even at our altitude with headers and stall.

 

Well I am going again tonight. I havent done anything to my car, other than removing the maf screen. A friend from work is going with his 2001 vette and he said he is going to let me take it down a couple times. I am almost sure I have 3.42 gears though. I usually run at about 2300rpm at 70 with stock rims and tires. I will let you know how it goes...

 

Well went to the track last night and had a good night. there was a 1991 b4c there, the owner claims it was stock and he was running 13.8's. any how i started by running where i left off around 14.011, with horrible reactions times. but as the night went on i was in the 13.8's and ended up beating him 4 of 5 times or so. i dont have the time slips in front of me, but i think my best time was 13.82 at 99.8 mph. i was pumped. i took a 2001 vette of my friends off the line a couple times but he always came back and beat me. anyhow i am where i want to be right now with this car, well alomst, i wanted to break 100. i think a tune would help this, but dont have the resources close enough to do. the track i went to is nebraska motor plex. they have one more open day and i may go i am not sure. i do not think i can improve this time without some other mods. i really like to beat mushtangs...

 

1.6 sixty foot times at NED on street tires and he only runs 12.6's? Sounds like he needs his vision checked because he must be reading the guy in the other lane... I'm not doubting the 12.6, but I am calling bs on the 1.6 sicty foot time on street tires. Even my buddy with the 2002 stock Z06 that has run 11.5's at 119 is only cutting 1.7 sixty foot times.

My sixty foot times are in the high 1.5 range with 26" tires and the mid 1.6 range with 28" tires.

 

Your car is running good there guy but its unlikely you have 3.42 gears in your auto without some way to program for them hypertech or programming your speedo is way the heck off base.
As I said does your shifter base have a 1 or only a 2 showing.If it shows a 1 you have 3.23 stock and if it shows 2 only you have 2.73 gears stock.3.42 only came in m6 cars.I swapped them in with the 3 series carrier in my
96 z but had to use hypertech programmer to fix the speedo error.

 

i could have swore that i read that some where that my car has 3.42 gears. anyhow, even with the 3.23 or 2.73 it is a good 1/4 mi time. my car says 1,2,d,od,n,r,p. so that means that i have 3.23s?
