Here are the details: Ran at SIR in Tucson, elevation ~3,000 ft. and the temperature was 70 on my best run. 04 base model Z with Nismo LSD, JWT flywheel, ACT street clutch, spare tire removed, and a little over half a tank of gas.

60' 2.161
330 6.152
1/8 9.423
MPH 75.82
1000 12.224
1/4 14.583
MPH 96.44

I am probably an average driver at best with < 20 runs total, 14 of those with my G35C. I took my Z to the track last night for the first time to see how it compared to my previous G35. I did 4 runs and my 60' times were around 2.25 and I knew there was a lot of room for improvement. My fifth and final run I got the 2.161 60' time that resulted in my best run. For whatever reason, my best run in my G35C was 15.0, which I easily beat all 5 times last night. My G35 was the first car I had taken to the track so the first runs were really slow with terrible launches, missed shifts, hitting the rev limiter, etc.

I was never really able to get a good launch with my G35 though. Maybe I have gotten better, but its hard to explain when all 5 60' times with the Z were better than any I ever got with my G35. I had 3 different tire set ups on my G35 during various runs. Pilot Sports on stock 18's, F1 GS-D3's on stock 18's, and Toyo T1-S on 19" Volk TE37's that actually yielded my fastest time with the G at 15.0. The tires on my Z's stock 17's are Falken Azenis RT-215's.

I am sure I can squeeze out another tenth or two with an even better launch, quicker shifts, and a 1/4 tank but I doubt I will ever run really low 14's at this track on street tires. I might try to get up to Phoenix to get a couple runs in before it gets too hot to see what I can get. I might also put some drag radials on the stock wheels when I get around to getting some aftermarket wheels. That should put me really close to a 14.0.

Does the Z's lighter weight compared to the G35 give it an advantage during launching? How much of a difference did the aftermarket clutch/flywheel make? I thought the difference would be seen more in the trap speeds but it doesn't seem to be the case. At any rate, I am pretty happy with the results considering its basically a stock car. My G35 had a Stillen intake/Z tube, Kinetix resonated test pipes, and Borla exhaust.

Some observations from the staging lanes, but I have no idea what kind of run they had or any mods: C5 Vette ran a 14.2 and 13.6, GTO ran 2 15.0's, 2 SRT-4's - one ran a 14.8 and the other a 14.5.

 

Alot of factors play into the 1/4 mile. There are so many variables to lookout for and its hard to consistently nail down that one factor.

To my experience running on the 1/4 mile tracks, the Z's stock suspension isn't ideal for drag racing. You can reduce your weight of the Z, but it causes a change in weight distribution. I actually lightened up my Z and went down to a 1/4 tank of gas and it really didn't do anything for my 1/4 mile time (I picked up wheelhop going into 4th gear). Of course the track I run at isn't the best in the world, if not worst.

Given your elevation, your pretty much on par with the 1/4 mile times at sea level tracks.

 

Thats good man. I have a 5AT and my track is at 3,000 elevation also and I used to run 14.9+ until I got my 3.53 final drive. Then I ran 14.3-14.6. Just get your 60ft time down and youll be in the low 14s.

 

Well considering you have LSD, and a lighter fly along with a stronger clutch with slightly less weight (taking the spare out and half a tank)... I feel better about my 14.6 time with no LSD, full tank of gas, and keeping the spare in

Any not bad times.

 

Update: Adding a JWT pop charger and gutting the cats got me almost .2 seconds. Temperatures were around 80 degrees and my 60' time was very close to my previous run.

60' - 2.173
330 - 6.108
1/8 - 9.330
MPH - 76.71
1000 - 12.083
1/4 - 14.396
MPH - 98.7

Not bad for 3000' elevation IMO. There was a M3 and the best time I saw him run was a 13.9. A couple of new mustangs and a GTO were running low 15's.
