C4 60-130 mph thread.
- 5.15 s: 84 big inch single turbo.
- 7.87 s: see Crispy video below (20.69 s-12.82 s time extracted from Stats for nerds). 7.76 s extracted from 0-130 video (even better).
- 8.42 s: 84 6.0 LS swap, TKO 5 speed.
- 9.85 s: 86 auto, Procharger.
- 10.33 s (estimate): 93 6-speed, Procharger (+4 frames for 128-130 mph interval, -1 frame for 58-60 mph interval = 93 frames, assume 9 hz, otherwise show me the data!).
- 13.129 s: 88 auto, Paxton, 2:59 gear.
- 13.6 s: 93 ZR1 (caranddriver May 1993).
- 18.6 s: 96 Grand Sport (caranddriver Jan. 1996).
- 19.1 s: 92 6-speed (caranddriver Jan. 1991).
- 36 years and still counting...: 84 auto.

86 auto, 4L80E, 3.73 gear, 383 w-heads, cam, blower, bolt-ons: 9.85 s.
Note: Time difference according to log = 9.85 seconds, but there were only 88 samples over the interval, so the average sample rate = 8.934 samples per second. The number of samples cannot necessarily be trusted as an accurate indicator of time since the actual frame rate can vary.

Does it make a difference?
How about from a 50 roll? Old cam, no nitrous, a little less boost.

I tried breaking the video down to sub 1-sec, but i can't. Scrubbing as slow as i can, its pretty close to 8sec from 50-130 already on the gas. Consistently traps 130+ in the 1/4mi with no prep, BUT no clue on the ET.

In the 90's Massachusetts had strict emissions visual and roller testing, I couldn't even touch the catalytic converter.
Paxton Superchargers some how managed a blanket CARB EQ, that covered all GM TPI motors.
I installed a kit from BlowerWorks and passed testing for years with paper work in hand.
Data bellow is a stock L98 with only Arizona large tube runners and a cat back exhaust.
I did hundreds of 0 to 150 tuning runs over the years, but they are very hard to sort through, I didn't label anything.
The interesting part is the first data bellow is with the stock 2.59 rear end, the second a few weeks later, same exact car with a 3.54 rear end.
Funny thing is the 3.54s are faster than the 2.59s in the quarter mile by 0.39 sec, but slower to 140 mph by 0.39 sec. and 0.73 sec slower 60 to 130 mph than the 2.59s.
Probably can blame the low fourth gear overdrive gearing.
1988 L98 Automatic:
2.59 gears:
60 foot (no rollout) = 2.257 sec
1/4 mile = 12.942 sec @ 112 mph
0 to 60 mph = 4.565 sec
0 to 140 mph = 20.955sec
60 to 130 mph = 13.129 sec
3.54 gears:
60 foot (no rollout) = 2.059 sec
1/4 mile = 12.553 sec @ 112 mph
0 to 60 mph = 4.074 sec
0 to 140 mph = 21.340 sec
60 to 130 mph = 13.856 sec

I think with my new transmission I can get my time in the high 8s. She is shifting liking butter on no lift shifts now. No more granny shifting and jamming through worn synchros.
Notably absent: times from LT1/LT4/LT5 crowd (except for the magazine times already posted).
I did find a 2018 V6 Camry test of 20.5 seconds to serve as a sort-of low bar. Also interesting to note: 93 Supra Turbo (15.3 seconds). Source for both: caranddriver.

As far as the rest... suprised Diz doesn't have data like that.. he's LT1 right?
i would like to know a good camera setup that will record this stuff !
i guess i could estimate it from a datalog from a drag run.
i usually stay on the gas past the finish for a little bit for tuning purposes

58 to 128 is the best I had data on. 9.0 seconds based of going from frame 6996 (58 mph) to 7086 (128 mph).
Note that i had 12 degrees knock retard come on in 3rd gear
90 frames elapsed , 10 Hz data capture rate = 9 seconds
this was on a 12.2 drag run. With a lousy 2.3 60 ft
due to the knock retard...
i reduced timing a degree or two up top for the next run.
i got down to a 2.0 60 ft on the next run but my lf muffler slip pipe blew off in 2nd gear at 6000 rpm. I let off bc i thought i blew the engine. should have stayed on it !
I became discouraged and drove home to lick my wounds
