what times are you guys getting... let me know what mods you've done too cause i want to compare the stock ones to slightly modded ones. I would ask what estimated 1/4 time i would get with my future mods but lets see some hard earned proof!

give you rear axle ratio too please!

my best(of 3 runs) was 16.06

thats with starting out in first and shifting into drive!

 

Last fall with headers and full exhaust, open air element air cleaner, advancing the ignition 6 degrees and 3.42 rear gears I turned a 15.006.

 

Open element, Ultimate TBI, Flowmaster catback, 1/2 TB Spacer, 3.08 open rear, 5speed, GMPP Lightweight flywheel, LS1 drivshaft. timing at 4*, with a custom chip.

16.16 @ 88.8 MPH (yes that is not a typo) with a 2.67 60' time (the track was like glass)

 

Well I don't have any ET's, but I got 10 HP and 8 ft/lbs by increasing timing 8* and an open element. Those are at the fly wheel by the way.

 

In the sig. This is with a custom chip, although the I'm not done tuning it. Oh, and 2.73 gears.

 

3.73 posi, T-56, LS1 driveshaft, open element, msd 6A, blater coil, full exhaust, and a completely stock L03: 15.7@91.44mph.......horrible '60 times 2.6X seconds.

 

Doesn't somebody have the TBI Registry still? That was a pretty useful thing. Whatever happen to that?

 

this is helping me alot thanx for the rpelys guys and eep them coming!

 

on the motor my best was a 15.44 at 87mph then with a friend in the trunk i cranked a 13.78 at 103mph

 

What were you you guys shifting at and in what gear were you crossing the traps at with the gears you have?

 

sig

 

Check out the link in my sig for the TBI time registry, that should give you some ideas. The things I do for TBI...

 

I run a 16 flat because I cant get traction.

 

I'm shooting for 13s once I throw on a set of slicks and skinnies.
Mods are in the sig.

 

88 IROC TBI/auto/2.73 open

stock I ran a 17.0 @80 mph. Thats at Calgary, Alberta, where the elevation is 3500ft but often worse due to the air.
60ft times were 2.4

NHRA corrects that to a 16.2 or damn close.

After getting my trans rebuilt with a 4.3 V6 stall, Corvette servo
and Trans-Go shift kit it ran 16.8 @ 80mph
60 ft times dropped to 2.3

For my last run of the night I switched to an open element air cleaner and did a 16.7 @ 82 mph

I am a beiliver in open element air cleaners now:hail:

So now at sea-level I would be a 16.0----maybe 15.9

 

Hey I got a 91 Firebird with all these special edition fully loaded features that were all ordered and installed by the manufacturer, and well it has a 305 TBI. Nothings been changed and I think I got roughly 60 MPH in 4 seconds with my wheels spinning and about 6 seconds acc. normally. I think thats good. But I don't know.

 

umm.....err....too many drugs for you

 

ummm, are you sure that wasn't the ferrari you were timing?

 

I know that sounds radicaly off and it might possibly be by maybe 2 seconds but not much more. I was at a complete stop I smashed the accerator and I had a friend time me until I got to 60. Thats what he told me. It does sound a little off though I'll try to run it again.

 

are you sure you speedo isn't off?

my car gets to 60 really fast now, after my gear chage

there is no way that a L03 car will do a 0-60 in 4seconds withouth alot of serious modifications, heck they only trap at 84 MPH (typically) in the 1/4 and it takes them almost 16sec to get there.

 

It won't let me see the TBI registry, says my computer doesn't support the file type

 

theres a reason why Car magazines use high tech equoment to get 0-60 times---they are acruate--stop wathc is a rough, rough estimate.

 

I know I wish I had some kind of access to some of that high tech equiptment. Down here in Illinios I don't have any access to anything like that. It sucks. Thats why I say that it might be off by a 2 or 3 seconds. Any ways the only reason I got to 0-60 in close to 4 seconds was because my wheels were spinning and I wasn't getting any traction. I know that really doesn't count but that was what I ment by that. Without spinning my tires your looking at 6, 7, or 8 seconds roughly. Inless the origional owner, or the mechanic, did some modifications that I don't know about or can't see, then I believe that everything is straight up factory. It's deffinitly no where near a base model firebird and thats all I know.

 

You might be a mid 6 for your 0-60, but you'ld have to be a strong running car for that. I was at 6.7 when I timed my car, and that's real good for a RS.

 

thats impossible for a stock RS TBI--if thats the case you could race 350TPIs and give them a run.
They'd (a TBi) run in the 14's in the 1/4.

It's called an acceleration curve--and the one you guys are purposing is impossible.

And to think--all those fools paid 18K USD (to buy a 350TPI IROC) when new.....suckers shoulda bought an RS.

Know what RS stands for? Really slow.

If your car can some squeeze of a 6 second run---it's not stock. 18-20lbs per hp ain't exactly a rocketship. It's physics--plain and simple.

At least try to G-tech it--be more accurate then a stop watch

 

Umm what? The reason you got to 60 in 4 seconds was because your tires were spinning and if you didn't spin it would have been more like 6,7, or 8? Umm so spinng tires makes you faster? Guys don't get all on this guys back for saying his car got to 60 in 4 seconds. No offense, but it sounds like he doesn't know jack about cars and is probably being honest because he doesn't know any better. A little bit of advice: Spinning makes you slower and never use a stopwatch to time yourself. It is flawwed!!!!!

 

anyway... back on topic:


i was running a steady 10.7x in the 1/8th mile.

only "mod" was a open element...

afterward the car got a cap, rotor, new plugs... i donno what it does now..

best 60' times were achived by holding the brake and loading the TQ converter.

near the end of the session, around 3am, i could do 6 runs in a row, back to back. it ran consistantly the same times within .04 secs.


i am seriously thinking of bracket racing this thing before i do any serious mods.. LMAO.

 

MrDude_1....what were your 60ft times? How about elevation--I am at 3500ft and got a 10.7 (2.3 60ft) in the 1/8--mine runs pretty good I think.

 

there are some good stories here...after my hedman hedders went in i'm sure to get my goal of 15.99! i really like the idea of my car being... a " 15 second car" call me a low dreamer but i'm happy with the little thing! especially since i'm broke as hell lol

 

Hey, I don't feel that bad now...LOL

My TBI'd L6-250cid '63 C10 (3600lbs) non-posi ran 10.935 @65.24 60'=2.578...my very first time out...I did a couple of mistakes during the run, but not bad my 1st time out...can't wait to try it again...BTW, I didn't load the converter and should have only gave it part throttle instead of WOT of the line...it takes off better.

CT

 

I wanna be in the 12's with like a 150 shot. I say my car how it is + headers, custom chip work and a few things here and there could do it hehe "12 second nitrous fed small block" just rolls off the tongue so nicely

 

i'll be happy when i have a N/A 12 sec smallblock..
i'll be sastified when it runs 11s and is still a daily driver.

 

amen, i am not stopping until i get kicked off a drag strip

btw, i want to go 10's on a small block TBI... that is my goal.

 

Wow, still to this day I have NO clue what happened to my car when I ran it that one faithful day. The ONLY performance mod I had was a flomaster 40 series muffler (still had 'H' rated tires), and my car ran a
15.3@87.00mph!!
Now I have an open element air cleaner on her, but living here in the state of Arizona its actually slowing my car down. Untill I get my ram-air hood I'm sucking in too much hot air. That and I just fried my electrical system, so she won't be going anywhere anytime soon....

 

The only thing that I ment by that was that I could accellorate to 60 faster but your right, that doesn't mean that I 'm going anywhere. I understand this. I just am not the best at explaining it. Since I'm not going anywhere, thats why I said that it didn't matter.

 

I just noticed something strange about my car... I know i had problems with the car the day i ran at the track... (and i still have them)

i ran a 16.401 @ 80mph (133km/h) with a '60 of 2.473

damn auto shifted a very slugish shift from 2-3...
I know i have some problems (can't find them though) but the strangest thing is that i'm running a 10.511 in the 1/8 mile...
I think i have atleast 1 leaky injector. I launched the car by just slaming it in 1st. Shifting manualy. I didn't try and raise the revs to the stall point when launching (big mistake)

One more thing... i've clocked the car meny times 7.6s 0-100km/h (0-62mph)... Think about it for a while.. 7.6s to 62mph.. 16.4s to 80mph. somethings wrong.. and bad. I did feel loss of power at about 1000' feet mark...wierd

 

The 700R4 doesn't do a great 2-3 shift under full throttle at all--in fact you have to let off the gas a wee bit. My trans was rebuilt witha Trans-go shift kit and Corvette servo so it does a great job of shifting.

My car too starts to really die at the 1000ft mark.

I doubt it you made any mistakes but not launching at stall point. I run 2.3 sec 60ft times but just puching it off idle--a tiny whees spin and I am gone.

I'd try just leaving it in D---manually shifting this car has always slowed me down.

How excatly did you "clock" your car 0-100km/h?
Stopwatch? See you are comparing two differnt types of measurements. The timing equpiment at a track is very acurate where as a stop watch is a
ball park figure.

And it's just the nature of the TBI to be strong down low and roll over and die at high speeds.

 

Yeah it was timmed with a stopwatch... about a million times same result +/- ~0.1

but lets say it is off 1 or even 2 seconds... that would still 7 to 8 sec to accelarate 20mph I know that the air is restricting at higher speeds but still...

And looking at my few mods i would say i was waiting more for like 15.5-15.9 times... The car did have a very bad day. don't know why, usualy it just pulls alot harder..

What would you say i sould be driving with the mod i have??? given that the car is healthy???

BTW heres the link to my run (divx 5.0.5):

http://barbara.macoline.com/~mpoukka...0ja%20Timo.avi

I'm in the red one...

 

Whats your time and speed and the 1/8 (1000ft)?

The only thing I can say is that acceleration curves are not linear. The acceleration rate will not stay constant. Especailly at higher speeds. Drag multiplies too. TBI is all low end with not much for top end (stock cam)

I ran a 16.7 at 82mph at 3500ft. The density altitude at Calgary is quite often at 4500ft or greater. That time I ran is the same as I did with my bone stock 87 Monte SS and that car ran fine.

 

reaction 1.082 (my first lauch )

'60 2,473
'330 6,827
'660 10.511
'1000 13,695
'1222 15,594
1/4ml 16.401

@ 133km/h (finnish drag strip)

help any... btw.. i found out today i have a leaky injector
gonna fix that tomorrow... i also had too much fp.. @ 13.5psi
now it @ 10.5psi... much better...

 

It seems that a bunch of you are getting really crappy 60 times and you stand to knock off over a half second by just getting a descent 60. Are you guys spinng real bad or are you just real slow out of the hole? 2.4+ 60's are really bad, lol. Get that down into the 2.1 range and you will be into the 15's easily. Some gears, converter, drag radials and and maybe a little suspension work, and you might actually be looking at possible 14's.

damnit, i can't open it

 

think about it.

most guys have a peg leg and hwy gears....


i have a 2.73 open rear....



btw, found a old slip 60ft was 2.3..


dynoed my car last weekend... numbers in sig:

 

I've got a pegleg and 2.73's as well, and I have trouble spinning the tires at all from a stop. I guess the crappy gears just don't get out of the hole very quickly. Some say they spin, but I have to try to make it spin to lose traction. Either way, 2.4 and above 60's can be improved upon greatly!

 

You're telling me.

 

perhaps your engines making **** for TQ?

 

Probably making about the same amount of torque you are, so if you are making **** for torque then I guess I am too.

 

239... spins the tires if i blip the throttle......

atleast... the pass tire spins....

in anycase, you should be able to spin them no prob... even the L03 makes a decient amount of TQ just off throttle..... and without a posi, even a proper suspension setup would allow them to break loose on a regular basis...

 

From a dead stop if i romp it i can get a tiny amount of wheel spin, but nothing major. I wouldn't exactly say blipping the throttle creates a lot of wheel spin. If you know how to drive at all it's pretty easy to control the power of the stock L03. Launching isn't exactly a science with a stock auto L03.
