Does your car weigh 2500lbs?

Dave B knows what's up. He mentioned Cecil-thats where I ran my 13.1 @ 107mph with bolt-ons, its true, some track, especially in certain conditions are flat out faster...that takes nothing away from the driver IMO though, still a damn good job.

How is this for a stock Z, first ever time drag racing? Where can I improve?
Thanks!
Good run! Its nice to see you pick up 23.34 mph in the last 1/8. This proves it is possible for a Z to pick up 23 to 24 mph in the last 1/8 without FI. When I posted that my car picked put 23 to 24 mph in the last 1/8 I got flamed because people couldn't believe a NA Z could accelerate that hard. They basically said it had to be a malfunction on the timing equipment or a strong tail wind.

well in sacramento and napa<infineon> the difference in times i have had was .2 on the quarter on my old car. and 1.5 mph difference. the reason also being that tail winds head winds and also the slope at the end of the infineon track.

I totally agree. You run what you run.

Not saying Fluid1 is guilty of this, but it just bugs me when people claim their car is some sort of "freak" or that they're some sort of world class driver when their car pulls above average times. Almost everytime, it can linked to the track and the conditions. It also bugs me when people improve their times significantly (.3+) and say it was because of their new intake or exhaust and then you do the DA calculation and figure out the DA and an improved 60' was responsible for the improvement, not the mods Just a change in 1800' of DA was good enough to take my G35 from upper 14.4s to lower 14.3s with absolutely no changes to the car or 60'. People just don't understand this stuff and they really should.

Think 23mph in the last 1/8 is realistic with a 6MT. 24mph is a slight stretch, but I'm sure it's possible under the right conditions. I know my 5AT G35 consistently pulls upper 21s/lower 22s and my old 5MT 96 Maxima would see 22mph. I don't see why a 6MT Z couldn't do a little better.

Just curious, how did you break in your car? Hard/aggressive or soft, like it says in the owner's manual...?

On the run I posted (https://my350z.com/forum/texas/115060-san-antonio-raceway-fri-3-25-a-2.html) I was able to run the last 1/8 is 23.98 mph but the weather was nearly perfect. I looked at the weather almanac and calculated the DA for that run at around -969 feet. The temp was 37.9, pressure 30.35, 30.9 dew point, cross wind of about 6 mph, and the track altitude is around 700 feet.

Damn, I saw the 2.2 60ft and was expecting to see a 14.1-14.3. Nice job.

I forgot to mention in my original post that there was also a slight headwind that night at Rockingham, so his 104mph trap is even more impressive.

Given the humidity, I didn't expect to ET very well but I was hoping I would trap better than 100. I hit 103mph on one run, 102.97 on another and the rest were pretty much 101 although the only run that my rad/clutch fan were not on was the 103mph run. I ran the damn heater nonstop trying to get those fans to turn off, but they just wouldn't. I was down about 15-20HP as a result of the fans running. I also had to really baby the thing out of the whole, or it would one wheel peel (no lsd). Here's my goof off video from the Rock that night:

Either way shoot me a PM next time you head to the track and if I can make it out, i'll bring my camcorder and get you on tape.
Cool, I didn't even know it was you! I'll defintiely let you know. I also didn't know you lived in Charlotte.... if we are doing any kind of motorsport I'll let you know...

Yeah, some cars are different than others, as are drivers. I'm not saying that me or my car is superior to anyone, unless you're talking about autox...

Thanks. This is the tough part for me, I have NO idea how I'll get my 60' down.

Go to a different track. In all honesty, Rockingham isn't the best quartermile to go to and is often referred to as "Slickingham". Maybe try Fayetteville or another quarter mile track. I also have an open diff on my car, but I know you should be able to atleast score a 2.1 short time. I've run a 9.00@80mph at Mooresville and on that run I ran a 2.1 60', so I'm confident that if you get your 60' down to a 2.1, you'll likely see low 13.7s, possibly a 13.6! Good luck.

I'm right at the 485/85 intersection. A stone's throw from Starlight movie theater and Verizon Amphitheater.
