What did everyone run in there 3rd gens when they were stock.
I never got to run mine 100% stock. But with only a hypertech chip, K&N's, eibach springs, and poly bushings I managed a 14.61@94.55 with a 2.03 60' and a 9.35@72.?? in the 1/8.

My only stock runs were my first two ever:

15.314 @ 90.23MPH w/2.430 60ft &

15.186 @ 90.04MPH w/2.328 60ft

Obviously I sucked and couldn't launch the car

 

I managed a 14.986 @ 91.5 with my 350TPI.
The fuel pump at them time was halfway rotten too, so I imagine the car shoudve run something like 14.6

 

My car went 9.50 at 74 in the 1/8th stock at 73,000 miles and then the next time I raced it 4 years (144,000+miles) later it went 9.50 at 73 in the 1/8 & 14.72 @94 in the 1/4.
It spun really bad & I had to feather it off the line on that first trip to the track, but when I ran it at after all those miles it really hooked up even on the stock tires. Still ran the same time, but a hair less MPH. I think it would've ran a tenth or two quicker back at 73,000 miles.

 

My first time i ran it i got:

60ft: 2.097
1/4 MPH: 91.80
1/4 ET: 14.97

My goal was to hit 14s bone stock, i mean, not even a tune-up was done. I started 15.5 on that day, but as i got more comfortable, i got better at launching and all, so very happy with time.

 

14.1 @ 99mph with a 2.3 60' time.
86 Trans Am WS6 Speed Density 305TPI 5 speed.

 

bone stock with 150,000 the iroc ran 15.2 @ 92

 

14.71 at 91+ MPH.

Bone stock...not even a tune up. I have since removed the CAT, installed frame connectors, aquired a 2002 Camaro SS take off exhaust and will be purchasing headers. I would like to see solid 13s before putting on my Vortec heads and swapping cams.

Basically I think full exhaust -cat, suspension work(boxes LCA, Relocation brackets,...), shift kit, corvette TC, free mods, and custom chip tuning should be able to put the car solid into 13s, no? After that Vortev heads and an LT1 cam I think I'll hit 12s....all this will require custom chip tuning, which I am currently learning and acquiring the equipement necessary to do so.

 

14.20 @ 97mph with slp catback...

 

Damn nice car you got there, and quick! is it 305TPI or 350?

 

My sig. below is with the little bit of mods I have. I think bone stock with 160,000 miles I ran somewhere around 14.80. I cant really remember because the time slips are long gone. I have made it a practice to save my time slips now by the way.

 

14.8 with 2.77's man that must be nice. I only got a 14.6 out of a 350TPI car with 3.27's

 

15.9 (only sub 16 sec run), @ ~85mph.

You think something might be wrong with my car?

I'm hoping that some new injectors will fix this "little" performance gap.

 

I had a TPI 305, K&N filters,adj. fuel regulator, headers, 3" cat back , 5 speed and 2:73 open rear, nothing more in the way of mods and I ran 15.4 @ 96 the first time I ever went to the track. I think it would have ran 14s then if I had traction and more experiance. I did not have the 305 in for long, so I never was able to find out.

 

Not bone stock but I went 14.1 on street tires with K&N, Flowmaster, pulley and not much else. That was my very 1st run ever and it was in the 97 MPH range, somewhere I should still have the slip...

 

i can do better, still have room for some improvment.

Best Quarter Mile: 14.50 @ 92
Best Sixty Foot: 2.05 seconds

 

I never realized your car was turning those kind of times at that MPH stock/close to stock. What mods if any at the time of that pass?? Id have to say by that MPH and that ET coupled with that 60ft you have a few, either way those are some nice numbers if they are stock or even close to stock...

 

I've got a small confession, the only things that were stock were the intake, plenum and runners.
I had a cam, 52mm TB, dual cai, headers, 3" catback, msd 6a, 87 tpi heads, centerforce DF clutch, no a/c or smog, and suspension work.
It was stock to me since I installed all the mods at the same time I did the TPI swap.
The funny thing was, the car was running in Limp Home mode the entire 6 weeks that my 305 lasted. Bad prom due to PP2 and Win XP Pro not working together. Looked like it was burning successfully, but wasn't doing a damn thing.


Here is my slip,

 

1988 GTA 350 TPI w/ Dynomax Exhasust and MSD ignition
13.7 sec/ 100 mph

 

FactoryFreak, DAYUUM I thought my engine was doing pretty good. You take the cake for the best times for the fewest mods for sure!

 

I believe the time...but not for those mods.

 

Thats why I scan my new best ETs just in case someone doubts my times or claims and if thats not enough I usually have video if at all possible...

 

Not a bad idea. It doesn't show what mods were done to the car though. Oh well, there will always be people telling 'stories' about their cars

 

All of my friends couldn't believe but they witnessed me do it. It was also on DR's and they aren't the orginal heads in the car they are stock replacements that got put in about 4000 miles back.

 

Might as well throw mine out. 14.5@93 on a 2.1 60 with k&n filters, gutted air box and 2.77. Present best in sig.

I wish I could run what FactoryFreak does and I have like three times the amount of bolt-ons...

 

i know mine can't be the fastest

13.8 @ 104 with a custom CAI and a full exhaust on michelin pilots with a 2.1 60'

it was 45 degrees out though.

 

I believe 104 MPH with those few mods IS the fastest L98 3rdgen Ive ever seen, nice numbers if in fact thats all you have on that run...

 

Well my '92 is pretty close to bone stock. Check the sig for mods and time.

I don't by the 104 trap above with just CAI and exhaust. Unless the hand of the almighty was pushing you along i don't see it happening. Just IMHO though.

 

LOL

 

"slp iroc" from iroczone.com ran a 13.9 on stock 305 with headers exhaust and ported plenum and all them "free mods"

 

The 13.8@104 was surely not done at a track but with a gtech which I have seen to be completely over-optimistic. While I can see a realtively stock L98 run high 13s with CAI and good traction (the lighter ones, formula, iroc not T/A) but 104 mph is completely unrealistic. That's a good 6 mph more than the best running stock Irocs I have seen. 6 mph translates roughly to 60 - 70 hp more. The stock LS1s I see running run between 103 - 106 mph and they are completely underrated at @310-315 hp.

Please just clarify if this was at a track or on a gtech and if it was a track a timeslip, although possibly from another car, would go a long way to convincing us you have a 1 of a kind fbody!

 

no, your probably right...........

can't please everyone can you, i wasn't the fastest L98 there at the track as those that were modified were in the 12's and some stock ones with radials were hitting mid to low 13's.

while i know that everyone believes the average L98 to run no faster than mid to absolute low 14's with less than 100 MPH it's not always true.

believe what you guys want as it's your own deal, just understand that there is always someone faster and stranger things can happen.

i knew if i had posted any slip at all it would be demed the wrong one. go figure....to each his own.:lala:

 

Not to say anything bad about it, but that slip looks just like an LT1. This is my brothers 96 TA, 287rwhp

 

I was in no way trying to be a jerk, it was just to show my absolute disbelief that a stock L98 with CAI, exhaust, and now a K&N and air foil can hit 104 in the quarter.
Like mentioned above, you are running what an average LS1 runs and they tend to put 300 hp to the wheels.
It just doesn't add up, you must be making at least 330 hp on a bad day to run that mph with I'd imagin an automatic? Is your car gutted?
If indeed this is all true, you shouldn't sell that engine because it is truly touched.
And 104 with such few mods is that rare. Just look around here, this is one of the largest gathering places of thirdgeners around. If it were so common, I'm sure you'd see more of them here, myself not included.
BTW, you trap better than my '88 in the 1/8 mile and nearly as well in the quarter. I have all the mods in my sig (granted its not tuned) but that car is making some decent power. You are lucky to be down only 1 mph or 10 hp with such a stock car.
I still don't buy it, but oh well.

 

Hey, where'd the slip go? I wanted to look at it again.

 

i have had done work on the computer.......but nothing extreme; it was running quite rich at the end. i'm sure it could have done better but i'd like more power so that's why i pulled it. for having 100,000 miles it sure ran well for me.

 

told you i pulled it..........i put it there thinking most would respect the fact that i bothered to post it. guess not so it's gone. think what you will.

 

Well, I know this doesn't really fit in but totally stock....

13.89 @ 98.17 : 1987 Corvette, 3335lb raceweight.

It made 211hp & 315ft/lb at the wheels in that condition.

 

raceweight...what was removed?

 

Eh nothing really.... just the spare tire. Its 3365lbs with the spare tire in it. Those weights are with me in the car.

 

my 92 z28, 350 tpi, 43000 miles pulled a best of 14.5 @94.35 stock with only ad of flowmaster, and a very in experienced drag racer, ME!only tried twice, if i had enough guts would try again, but hate to tear it up dragging.

 

1991 Formula 350 TPI, all stock, bald tires... 14.3 @ 98mph.
With a fresh set of tires or drag radials I'd like to think it'd have run 14 flat or better. Now its no longer stock, so its hard to tell.

 

See sig.
The first time to the track when it was all stock and on street tires I ran 14.202 @ 96.20.
With the suspension and drag radials it went the time in the sig, the day after I did that run the intake started leaking coolant at the back, so I pulled it off and ported the plenum and intake.
Have lots of time slips in the 13.8 to 13.9 at 98 mph.
