Besides just raw times I think it's interesting to see how the times were accomplished. Two cars can have identical times but very different runs. So let's post up our slips.
Here are the guidelines:
1. Post a pic of the car
2. Post a pic of your best time slip
3. Sentence or two about the engine and mods.
Ready... Go!
SR20DET, stock T25 turbo @ 10psi
My first time ever on a drag strip, but I had watched a YouTube of how to do it. First run on the right. I only did two runs and wasn't ready for the lights on the first run. ...I'm learnin'
Jury rigged 2.5L engine where a 2.7L should be. Head is probably cracked. Tiptronic (auto) transmission. Clean on the first run. 50 shot of nitrous on the second.
Stock VQ35 in a 2400lb car with a 75hp, and then 150hp shot of nitrous. Nitrous shot size made no difference because of autocross tires out back.

dude, you really need sticky tires! with similar MPH at 1/8 and 1/4, my previous V8 Corvair ran 13.78 and my V8 944 ran 13.96. both hit 2.0x 60-foot times.
In reply to AngryCorvair :
He babied it off the launch after launching the driveshaft on the first run.
Red Mustang I obviously need something better than 340 tw Indy 500s.
stock Mitsubishi 15g, 3"dp, intake, manual boost controller, race gas, slicks and driver mod, photo shows headlight delete for our 3 final passes!
In reply to AngryCorvair :
Yep. Andy is correct. The Hoosier road race slicks stuck well when warmed up, but apparently I don't know how to launch with traction.
After I patched the driveshaft up, I came off the line real easy with cold tires which spun clear through the top of 2nd gear.
Knew I should have kept those little receipt thingies.
I'm trying to figure out the significance of the different distance measurements-here is a decent starting place.

In reply to AAZCD :
I don't think you're reading those the right way-your R/T shouldn't impact your ET...the ET doesn't start until you trip the sensors at the starting line. In your second run you gained .3 sec in the first 60', and an additional .6 in the first 330', and another .1 or so by the 1/8th.
Going by the above link, you definitely had a better launch (the .3 gained in the first 60') but your shifts and/or shift points netted you the additional .7 according to the 330' and 1/8th time. No idea how you gained an additional .5 in the last half of the second run.
If anybody has a better interpretation, speak up...I'm looking at this stuff for the first time.
In reply to CrustyRedXpress :
Mostly nailed it.
Remember time speed distance and their mathematical relationship. S=d/t
If you cut time from the first 60 ft it stands to reason that you are going faster at the 60ft mark and the next distance will automatically be covered in less time.
Cutting .3 from a 60ft (huge improvement) could translate to 1 or more seconds off of a 1/4 mile et.

Holy crap, a 1.700 60’?!?!?!
I will edit with a pic of the time slip when i get to it later today. 92 mustang lx 5 speed. trickflow heads and intake, f cam, 3.08 gears. 100 shot. best time was 12.7 @ 113mph

Stock 15g and 106mph didn't add up for me at first, but i looked up the compressor specs and considered vehicle weight and now i believe it but damn.... you really maxed that thing out!! Well done!!
Very little Studebaker left on this car. Vortec 4200. Only modification to the engine was valve springs. Precision 5976E turbo. Homemade intake and exhaust manifold. This thing is a torque monster. All 1/8th mile, no 1/4.
4.8L. 7875. Timing system clearly screwed up. Should be 138mph. Was hazing the tires the entire length of the track on last pass. Had a lot more potential. Just ran out of time.
In reply to Vigo :
Thanks! Gonna dyno and weigh it soon hopefully
In reply to TheV8Kid :
I thought it was great that you drove both cars. Your dad talked a bit about that Saturday night at my bar. You can tell that he's humble proud of you.
In reply to TheV8Kid :
Those 60’ are close!
In reply to Stampie :
Thanks. It was fun
In reply to Pete Gossett :
Yeah. Sunbird should be way quicker.
1980 AMC, Ford 302, 3spd manual trans (grrr). Had 100 shot of nitrous ready to go but never got to use it. We were using 28 inch drag slicks at about 15 psi (also didn't get to play around with pressure because of trans).
1st run was basically an idle launch, goal was to get a time. I also shifted from 1-2 too late and hit the limiter. I was thrilled with 14.5. does anyone have a clue why mph is so low on this run?
Second run i launched much harder and improved the 60ft a lot, also nailed the 1-2 shift. But then the trans got stuck in 2nd for basically the rest of the night.
the car probably has a 13 in it NA if the trans could cooperate. Maybe low 13s on nitrous. (Ifs and buts)
In reply to Robbie :
I've gone 14.4@93.5 before, it's not out of line

Yep. Aerodynamic drag increases exponentially with speed.
