OP - what was the DA? Shift points? What kinda RPM were you seeing at the strip? Make any other passes, and if so, what did those slips look like?

it was shifting at around 6k and the 1st run i ran REALLY bad high 14 @ 94mph 2.2 60' 9.67 1/8 @75. 2nd run i ran the 14.0 And the last run i ran a 14.21@96 2.1 60' 9.11 1/8@77.62. Times definatly show that it was the first time ever racing.

Any idea what the DA was? I wouldn't think it would be all that high this time of year in Virgina.

I dont know what the DA was. Ill have to check what the rev limit was set at And i knew the first time would be the bad but i was atleast shooting for 13s. I felt a little better after i picked up about a second between 2 runs. Maybe it will just take some track time to run what it should as i get used to the car... But like i said stall, gears, and longtubes are next on the list. I bought a cutout when i went to the track so maybe ill pick up a little from that ive read the flowmaster doest flow good.

flowmasters suck... also stall and gears are really killing you. autos are such dogs without that stuff... hell I did 13.6 with a couple of silly mods (short throw, flowmaster). granted, that was at Etown which is like sea level haha

You should easily be doing much better than that. My pig-heavy vert ran 13.99 at 99 with A4 and 2.73 gears and a full tank of gas. Other than cai and catback, it is stock. Never even had the valve covers lifted.
I managed to get a best 60' of 2.01 with off-brand street tires. Of course, people were using the track to get ready for the gatornationals that night, so I think the track was coated in super glue. Best I have gotten since that night was 14.1 with a 2.12 60'. But yeah, you are leaving a lot of power either under the hood or in streaks on the track.

lol e.t experts !! e.t SUCKS. It's BS. look at his mph and wtf with those mods he SHOULD NOT be running 100 mph. I saw a STOCK 97 z28 along side my brothers new 97 ss run 100 mph. I ran a 15.5 @ 127.8 mph anyone care to explain that ?
My guesses are:
compression error
cam installed wrong
Needs a tune

I say forget spending money on LT's.
Get the tune done (verify it with a dyno tune - or street tune with WB). Get a nice stall (3200-3600 somewhere in that area), and get some gear... 3.73's would be nice for a driver.
You should be able to trap 110-112mph with the shorties...

ill try and make it to some other tracks to see if i can get better. And i have read that no stall/gear really kills an auto but i would think it would run alot better. I think it either i havent gotten enough exsperience racing and/or not getting the rpm's up quick enough. And i also was on 3/4 tank of fuel since i didnt plan on racing it and i already filled it up a day or two before i decided.

It wouldn't matter if you run a 12.9 at 100mph that wouldn't be impressive either. Your dam MPH is down. If you put your car on a dyno I would put money on it that you wouldn't brake 300rwhp

Agreed, 100%, as I've been saying all along, MPH that low, with that little pickup on the back half is more than a stall/gears issue. If all the basics check out with fuel pressure, knock, timing, then I'd get on a dyno and dial things in. There is no reason you should run slower than my stock 'vert with full bolt on's/cam.

first off the car is a 94 z28 a4. finally got the car out to see what it would run. The best i ran was a 14.06 at 100 mph. With a 2.28 60'. I have a stock bottom end with stock aluminum heads ported and decked .020. 55cc chambers. comp 987 springs, seats, shims. They have stainless 2.0"/1.6" valves. Comp cromemoly retainers, locks and viton seals and 1.6 rr. And the intake has been ported to match heads, Shorty headers, no cats with flowmast muffler, moroso intake, and a madz28 tune.
I wasnt to impressed with the time i was running and think it should run a little faster. What do you guys think. I plan on getting a stall,gears,longtubes,and a cutout.

Ill help you out..
First, the stock converter needs to go. For your setup Id look at anything from a 3600-4000 stall to make your good gains.
Next, swap to 3.73+ gear, this helps to get in your powerband quicker and stay there.
A set of LT's will make a big difference as well, the shorties are killing your midrange.
Finally, get a set of DRs to cut that 60".
With the new stall, gears LT's and tires, you should be in the mid-high 11's easy, barring some abnormal issue.

As its been stated before, ET doesn't mean jack, but that MPH is telling you something - your not making the power you should be.

Where do you people get off thinking that his car, trapping 99-100 mph, only picking up 19mph in the back half, as it sits now, isn't an abnormal issue. All the converter and gear in the world isn't going to matter if the car's down on power.

Your car is starting off in each gear well below where it makes any kind of power, Put it above 3500 in each gear and i guarantee that you will pick up 6 to 10 mph at the end.
That cam and 3.23 gears is like putting a trailer behind the thing that weighs a ton.

It still doesn't explain away the really low trap speed - in the back half your not in subject to the big cam/stock stall fail that you're getting off the line, and the car should be picking up more than it is. You shouldn't be making stock or less than stock power in the 4000rpm+ range that you're seeing on the back half of the track, but your numbers say you are.
