official 1/4 mile track times

hjo1078

Thanks for the encouragement @sharpbycoop ! Yeah the bug got me good, all i wanna do is run my car now lol. I have some nt05rs on standby, i was practicing on an old old pair of nt555rs, I wasnt too impressed with them, took extremely long to warm them up and i just couldnt get traction on launch. I've got a private track rental in two weeks and will bust out my nt05rs. Hopefully i can improve that 60ft time to 1.6-1.7 or better lol. What is the best rpm for launching on a 6mt?

I went from mid to low elevens when my tuner told me to STOMP on the pedal to build boost on the third yellow light, and then let go of the brake. Watch my vid in my sig line.

Good luck!

That was a perfect launch.

Went out today with the same result. Tried it in auto and it actually seemed to be .1-.2 seconds slower than when I shift in manual. I talked to a few people out there and it sounds like my biggest roadblock to hitting low 13s or a flat 13 is probably the heat and humidity down here. One guy told me that running in 50 degree weather and running in 80 degree weather with humidity tends to be about a .4-.5 difference for him in a N/A car. I'm also thoroughly convinced that the K&N Typhoon is robbing me of power on my launch vs. the OEM intake system, despite the several people who have told me it's better. I think there's just way too much heat under my hood after sitting around waiting to stage, then staging in this Florida heat.

The other problem I seem to have is that, even after pulling the brake lamp fuse (confirmed by testing my brake lights), I can't get my Z to do a standing burnout, and I can't get it to rev any higher than 1800 with the brakes applied. I understand that a standing burnout isn't really necessary on street tires, but I'm more concerned with the inability to launch any higher than 1800. I've looked all over these forums and everyone else seems to be able to do it just fine with the fused pulled so I'm stumped.

This was my best run for the night. Going to give her a rest for the summer, figure out the fuse issue, put the stock intakes back on and sell these K&N Typhoons that are drinking hot air while I stage, maybe slap a couple of bolt-ons on her, then see what I can do this fall when it cools off down here.

DA for your run was equivalent to 1527 elevation.

Corrected, not precise but 13.35 at 105.4 mph.

79 dgrees at 66%humidity

I looked it all up using dragtimes android app, you can use dragtimes.com as well.

Still, 13.3, nothing to be ashamed off, faster than alot of cars

Here is a POV video from Sunday at the track. I had it aimed to high so you cant see much. I do have a better video of me launching on the street.

Good Job; yes the heat definitely affects everything....not sure if your ~Z~ is a sport or base.
My base had an open diff & a standing burnout would not evenly heat tires;;;clicking of the spider gears after letting off occurred.
Installed Quaife & haven't been to track yet/ but draws 2 even Black lines.
Made a total of 6 passes stock/ best was 13.1@just under 105 & put in modified class because of K&N drop-in's...lol

What kind of weather we're you running in? Mine is a base model, so I think it's an open diff. I'm not necessarily trying to burn out per se, I would just like to be able to launch higher than the 1800 rpm the ecu limits me to with my brakes applied. Pulling the stop lamp fuse didn't change anything. I think I'm probably just a little jelly of folks running 12.8-13.1 with a stock setup and my best has been a 13.6, but I guess I can blame it on this Florida weather. I'd still like to be able to launch higher since I get no wheel spin on the track with an 1800 launch.

Weather started good that day,but took them a couple hours to get track right,,,around 60* air temp....Ran on Goodyear all season 275/40/18's with a good burnout....could not avoid water trap,,,also they use VHT or something on track/Sticky.
Logged a best 1.95 60' without holding rpm's up....only around 8-900 & flashed it hard.
Noise after slightly powerbraking the burnouts made the clicking noise after I let off gas: sounded bad ;;; but I knew what the noise was.
Going back after I get a tune.

Bout forgot; ck your rear alignment/ eccentric bolts will allow you to dial your camber a bit more positive; allowing the tires to be more upright,,,,but will also increase rear toe (gotta have some rear toe)
Max out your camber eccentric bolts (pushing bottom of tires out) & then adjust your toe eccentric bolts to put back in spec.
I got rear camber arms now, with a more upright setup....putting new tires on tomorrow/ got the camber pulled + as much as the toe bolts will allow/// probably still around -1.0* (+ or - a tad)
uneven front yard,pics are a little off.

Whenever I post here I feel like I'm late to the party lol. Anyway I took advantage of the cool air today and got a better time. Still haven't hit the dyno with my mods.
