dragstrip asked me to work for them this sunday so at the end of the night i asked to run my camaro.
times were done with stock aircleaner 2.73's wit a posi full interior plus an amp and half a tank of gas. takeoff was really crappy as it was my first time going down the track ever but im pretty satisfied.
reaction: .569. .000 light is perfect at 42, yes terrible i know.
60 ft .2.260
330ft 6.576
1/8 et 10.197
1/8 mph 66.45
1000 et 13.27
1/4 et 15.964
1/4 mph 84.93

assuming a perfect light i have a baseline of 15.395.
dont these cars usually start out iun like the 16's?
had almost no spin off the line due to my takeoff style which sucked, dude rushed me and i didnt figure out the optimal launching rpm.
going back to race this wensday or tuesday to perform more time trials and to try out an open element.
what doesnt really make sense is that the motor can do that well with the stock induction setup on top when these motors arent supposed to do that well anyways. cant wait to put the new airfilter on,, think ill see much of a difference?

 

Reaction time has nothing to do with your total ET. You can sit there for 4 minutes before you go and still run a 15.9 like you did. Your times seem on par with every car. Where in ohio did you run? Are you sure you have a posi? I doubt you do since I didn't think you could get it but I have been proven wrong before.

 

that time seems about normal for a healthy L03.

 

for bracket racing? are you sure?
yes i have a posi i had it put in myself.
dragway 42 in west salem.
i've worked at that track for two years and half the time people there complain about their et's its because they didnt cut a good light and it screwed up their et.

 

this here is what we call a blow to the ego.15.9 vs 15.3, grrr.
think i could get a 10th out of an open element air cleaner?

that's allright this car doesnt have to be that fast. however when i get my lt4 powered nitrous enhanced 92 rs h.o. done,, it better move a tad quicker.

shifty what was this i heard u say about wanting to get rid of your car?

 

All that work and no gear swap too?

EDIT: Who said I wanted to get rid of my car? Which car?

 

the gear swap is the hard part, putting in a posi is easy, slap her in, and set backlash.

when you do gears, you have to set the pinion depth, with is no fun, and can require you to press the pinon bearing on and off several times, to set the shims up properly.

 

Yea I am aware, I was trying to nudge him a little., I should have put a in there.

 

Do you two know each other?

and with a name like ann.racer, i figured it was a female posting

 

I have no idea who he/she is. I always raz the local ohio folk. I wonder who told them my car was forsale The 95, maybe....the RS....NEVER!

 

hah, ann. is for anniversary. thank you very much.
im glad i have 2.73's i drive this car every day.
chris i was reffering to what you said in the last post about turboing a tbi, that you couldnt wait to get rid of it perhaps i was mistaken.
dude your other camaro is a 95? i have a 95 3.8 out here, you need any parts? its pretty screwed externaly ecpet the doors and hatch are fine, whats your car run in the quarter? the rs i mean

 

i didnt clarify i am a dude. thpugh there is a chick wioth a 91 in my town that has a red leather outfit to match the red on the camaro,, ehhhhhhh....

 

ok, as long as you reconize that i am THE dude.

 

Ah I gottcha now. YEs I did say that but what I meant was getting rid of the 305 TBI, not the car. Yea, the car is one of those things I think I will always have no matter what other fancy car I may have at the time. The 95 is good as new so I don't really need any parts. Thanks though

 

Ha, that's good stuff.

 

About the same times i run and i've got full exhaust, yet no posi.

Your time is pretty average for most LO3s. My times are in the sig and I'm going back to the track this wednesday hopefully bustin into the 14s.

 

15.9 is definely good. Not GREAT, but good. Yeah, lots of em' start out in the 16's (and 17's, but most of them don't admit to it) so you got a good car. Don't know how well you take car of that car or when the last time you had a tune-up was but that could get you a few tenths right there! Anywho, keep us posted with whatever you do to break that 14 second mark...

92 RS:

1st run: 18.34 (had the defroster on, forgot to turn it off)
2nd run: 17.9 (car was hot)
3rd run: 17.6 (car still hot)
4th run: 17.1 (car not as hot, but still finding best launch)
5th run: 16.9 (car cooled)
6th run: 16.7 (car was cool, but sat at the line after burnout
cause track was being cleaned)
7th run: 16.47 (car cool, took off stock airlid)


Best so far: 16.05 with a dynomax cat and catback, custom CAI, and free mods.

 

on my first 3 runs with my L03, they were in the 17s...

then i remembered how the tach gets off on these cars... so i "overreved" it (manualy shifting the auto) and got low 16s.

lowest i got it stock was 16.00.. and with a at track weight of 3615lbs, thats not too bad.

 

so im really not doing bad at all for it being my very first run considering. though my car was actually cooler then i would have liked, it ran for 3 minutes before the run. im thinking of putting an open element on it and possibly a shift kit, 700 r4 shifts too loose for me.
perhaps not a freak then, but a good day at the factory?
shifty you never said what your car runs dude.

 

hey shifty i'll give you 20 grand for the RS as it sits you dont even have to put it back together... bet its for sale now jk man

and nice numbers i really want to go to the track in the near future but dont know when i will get a chance... i want to see how the ol L03 scoots down the track...

 

It doesn't run. A slight run in with a concrete wall has made her my new "project." I wrecked it the day before I went to the track over 1.5 years ago

EDIT: Sounds like a test and tune night at national trials patrick

 

body panels are overrated.

 

i donno man.

i drove my car for 2 days without a hood...


i got ALOT of wierd looks...................................................

 

Haha, when I drove my with my hood off for a few months I felt like the biggest *******...I loved it!! So many people would look over and give me the look like "Ummm, you're missing something", made my day every time

 

wow. didnt know you wrecked it dude. you're at itt tech right? im thinking of going there after highschool. im taking autobody at the jvs right now maybe i could lend a hand, i did all my own body work for my black 92 and the red 92 is going in this year to get straightened out. ill sell you the black one it looks sweet and you could just transfer your stuff over to a straight car but i want your wrecked car after the performance stuff is off it and i need the interior, the red one is planned to have an lt4 (425 hp) dropped between the fenders and is my new project! whaddya say bro?

 

thats right .. all you need is the frame and wheels , drive train and a seat and stering wheel, the rest in jsut dear weight.

 

15.9 is about what a stock camaro ran, new. it's pretty good that yours still runs that all these years later.

your e.t. and your reaction time are two seperate issues.

the clock starts running when your car moves forward and un-breaks the two light beams at the starting line (to be precise, it starts when you un-break the second beam) and stops when you break the light beam at the finish line.

your reaction time is how much time elapses between your getting the green light and your un-breaking that second beam. the quicker your reaction time, the better your performance against the car in the other lane, but it has absolutely no effect on how long it takes you to get down the track. for example, if you were running against a car that ran the exact same time as yours and you both had the exact same reaction time, the race would end in a tie. rewind that, though, with both cars running the exact same time, but your cutting a better light (having a better reaction time) and you'd win because you essentially gave yourself a head start by leaving sooner (leave too soon, though, and you get the red light).

if you've been at the track that long, i'm sure you've seen the argument among bracket racers when a car loses AND breaks out. that means the other driver simply cut a much better light.

another thing that's terribly misunderstood is "deep staging". as you roll into the lights, your front tire breaks the first light beam, and the first yellow light comes on. as you continue to roll forward, your tire breaks the second beam, the second yellow light goes on and you're "staged". that second yellow light will stay on until the wheel rolls all the way through it and goes beyond. depending on your wheel size, the distance between when you first break the second light and when you've rolled all the way through it is around 12 inches. this is called rollout.

when a driver has a car that doesn't hook up very well and they want to improve their reaction times, some will roll further into the lights, sometimes rolling all the way through till the first light goes off. that's deep staging. this way, their car doesn't have to roll 12 inches or so before the second light goes off and the clock starts. this can improve reaction times, but it actually slows the car down a bit. when you stage shallowly, you get 12 inches of free rolling room before the clock starts. you essentially get a rolling start. even this little bit of rolling can add up to a couple of hundredths of a second in e.t.

as a rule of thumb, you deep stage for reaction time and shallow stage for e.t.

i am now through pontificating (for the moment, anyway)

 

okay, so considering it runs this well for what it is and that its almost completely bone stock since we've been looking at it more carefully, is it worth it to throw an open element on it and a full exhaust? i know that these cars in particular are unpredictable but,,,.

does anyone know the ,,, whats the name for it,, volumetric efficiancy is for these vs volumetric capability? i'de like to do the math before i take out the cash you know? like make a map of the airflow and figure out the weak points because all i really want out of this car is like a 15.2 without losing my gas mileage. once i can start chip tuning ill tinker with it and im going to switch to high test once its justifiable with mileage.

 

Freeing up the breathing and exhaust on this car will only help in the gas mileage department. More work is done by the same amount of gas since it doesn't have to fight to get in and out. But the gas mileage is adversably affected by your right foot and how your drive. With added performance your gonna want to use it more often.:lala:

 

usualy just put it on cruise on the highway but otherwise yea i see your point.
actually i i have a disagreement, i dont see how freeing up the breathing will help fuel mileage because since we're not doing a "major" mod it will still take the same amount of air and fuel to make the same power just at a lower rpm, see what im saying?

 

You are missing a few things to take into account. 1 is how the computer deals with fueling at diffrent TPS values, and diffrent MAP values. You see, the computer adds more fuel, as load goes up. the more power available, the less load on the less fuel used.

You also have to take pumping loss into consideration, with a free flowing exaust, it lowers the pumping losses during an engine revolution. which = more power availble to the wheels = less load = less fuel = better milage.

wow, k yea.
i have much to learn,, which is good, keeps me humble
