went to atlanta dragway for the test and tune friday night. here's the times:


08.15.03 Run 1 Run 2 Run 3
Time 7:28 pm 8:43 pm 9:43 pm
R/T .835 1.403 .869
60’ 2.541 2.534 2.510
330’ 7.084 7.096 6.979
1/8 10.889 10.846 10.667
1/8 MPH 64.46 65.90 66.38
1000’ 14.192 14.056 13.876
1/4 16.968 16.771 16.586
1/4 MPH 81.12 82.87 83.02

1. don't give me any grief over the reaction times. ha ha ha. it's been 15 years and i've never been on a 3 light tree before. at least it's a .500 tree.

2. there's a problem with my msd6a box, tach goes to zero after 3,500, so i was shifting blind. i short shifted on the last run (especially into 4th gear) and did much better.

3. launching is tricky with the 3.08 single traction rear. bogged on second run (hence the slower 330' time). launched the hardest on the third run. despite the wheelspin got the best time of the night and best 60'.

have a 3:42 posi ready to be installed. i'll be curious to see how the gears and posi improve the times.

went to year one's braselton bash on saturday. bought a g-tech pro. the damn cigarette lighter has no power, so i can't use it yet.

 

ahhhh crap. the table didn't take.

ha ha ha .... ok, let's try it this way

The 3.42 posi will definetely help, especially the '60 times. Also, make sure your msd is working properly and is producing the spark you need.
Try playing with your timing as well. Advancing it 4 to 8 degrees can really make a difference. Making your fuel regualtor adjustable is also another helpful mod.
What kind of air cleaner are you running?
BTW, you reaction times aren't that bad, especially considering the length of time its been, well other than the second run

 

pretty sure the msd is working ok. apparently, there's a filter i need to fix the tach. going to call them tomorrow.

i have a vafpr, just need to install it. i wanted to run the car once "as is" to establish baseline times. i don't think 16.5 is bad for what i have. it's a shame though, that gm would market a 5 litre so much slower than a 5 litre musiang of the same year. there were a ton of mustangs at the track, and so few camaros and firebirds. they were all pretty quick, too. i'm definitely an f-body fan, but it's abvious that ford won the ponycar war both by making the mustang a cool "chick" car, and by making it cheaper and faster than camaros and firebirds. it's sad. in my opinion, the 4th gen camaros and firebirds, while fast, completely got away from the concept of ligh, simple and clean ponycars.

anyway, back to the car. i have a k&n filter in a factory air cleaner base. i also have a factory 84 trans am cowl induction setup, but the flap is controlled by an electrical switch that isn't working. my power door locks, dome light, cigarette lighter and that switch have all quit working. i'm guessing it's a fuse. have to take a look.

 

That 3.42 posi should definitely help. You could stand to knock off close to a second if you could get that 60 down in the 2.1 range.

 

With posi and flowmaster mufffler I was able to run a 15.7 on a cold night a few years back there. I wish they would prep that track better. I can never get it to hook up there.

 

91 --

i feel for you, the local track here sucks too, i can never muster better than a 2.5 60' and can't even break into the 15's , although i trap between 86-88 mph. it sucks cause i know there is a mid 15 sec run in this car, with some traction.

 

actually, i was surprised at how well it hooks up. when i was racing regularly years ago back home at the orangeburg (sc) dragstrip, they put in a concrete launching pad and none of the cars with street tires could hook up. the concrete was "green" and had no rubber embedded in it.

my firebird actually hooks up better at the strip than it does on the street. i had to add another 500 rpm to my launch to keep from bogging. i guess it's because the concrete pad's been there for years and is "seasoned" with lots of rubber.

you may already know this, but a few tips for getting a street car to launch at the track on street tires:

1. stay out of the water in the burnout box. on street tires, water can hang in the treads, then drop on the starting line while you stage.

2. don't do long burnouts. when you do a burnout on slicks, the heat causes oils in the compound to come to the surface, giving traction. street tires don't have these oils (don't know whether that's correct for drag/street tires like mickey thompsons or nittos).

3. lower your air pressure, but not too much. if you go too low, it can make handling on the other end of the track "interesting". i dropped mine to 24lbs and didn't have any problems.

drive around the water, do a couple of real short "churps" to clean the road debris off the tires and go to town!

 

here are my times from 2 years ago. first time i had ever run a car at the track. 305 TBI 2.73 gears.

R/T .961
60' 2.282
330 6.676
1/8 10.391
MPH 66.45
1000 13.565
1/4 16.262
MPH 83.83

have only run the car once since, it was after the 350 swap. pulled a 16. stock heads, cammed some, stock manifolds, and no Ultimate TBI mods. knock sensor and ignition module were still 305 then too, pissed me off and i threw the time slips away.

 

I had about the same results my first time to the track. I just had an open air element and a Hooker cat back and I ran around a 16.5.. After learning to launch and increasing the fuel pressure some I got it down to 16.1.
