New personal best time
12.343 @ 114.14

Car was a very fast today, had to chanage the fuel map twice before i got it right.
Next week same car with a fully built GTM tranny/
Going for J nauts record of 12.2's
1.801 60 ft times
1/8 th in 7.935 @ 88.40

^^^ THAT'S impressive. Well played. :)

Nice :tup:

New Personal Best: 13.37 @104.76

Running on Bridgestone RE-11 305/30/19

My first three runs where 3.38, 3.37 and 3.38. Running 25psi Those where the best, after that I tried adjusting by lowering tire pressure to see if I could get sub .2 60' times, but they just got worse and I forgot to bring the air pump. Went a couple of times at 22psi, and my 60' where 2.3/2.4 had horrible wheel hop and worst times (13.6/13.8), seems these tires like more air.

Track temperature was around 75F, I'm still not pleased with my trapping speed, fully bolted and tuned, removed (Spare tire, jack, etc..)

There was one run where i trapped higher 13.38@ 105.31, 60' 2.16.
what you guys think??

I'm running 13 flat on Michelin piolt SS tires at stock 35 psi and only have an exhaust. I'm mad I couldn't Breakin to the 12s when I went last time too had all the tracks around me are closed for the year. Oh well intakes will be here soon then a tune for spring. Maybe ill take out my spare and stuff too next time lol

Also I ran a 13.3 in 95 degree weather before too

Can anyone with...
 

12.99 timeslips help me out here.
Due to poor timing, I haven't been able to get to the 1/4 mile since I had my uprev done. Well, tonight Lakeland dragway was running 1/8th races. Was experimenting with different shift methods (paddle shifter...auto trans...produced the hardest shifts breaking the tires loose on both the 1-2 AND 2-3 shifts). I'd like to speculate what my 1/4 time/mph may have been.
1/4...039 rt, 2.077 60ft, 8.71 660ft, 83.3mph, 13.42@104.6 78*
1/8...194 rt, 2.035 60ft, 8.43 660ft, 85.4mph...????? 58*
these are the best runs of both days.
I know, it doesn't count until I submit the slips AND the 1/4 mile time is just speculation until I actually run it but I'm curious.
Next time I'll experiment with tire pressure to reduce spinning.
Thanks to anyone who replies (in kind...I know the haymakers are coming too...lol)

Has anyone run with bolts on only at least 320 whp?

For reference, just about all my 12.9 and 12.8 runs were 8.3x @ 86.x mph 1/8 mile times.

I'd sure like to know how some of you are hitting low 13s and high 12s stock. I cannot break 13.6, even with lowering my rear tire pressure.

Are you guys dropping in some racing fuel for added boost?

thanks...will try lower tire pressures next time. raised my shift light to 7700 rpm which resulted in tire spin on the 2-3 shift as well as 1-2 (long chirp) so I know there's more to be had.

first off, i have a natural advantage..I'm just about at sea level. (although my disadavntage is I weigh about 235)
I have the FI exhaust and stillen G3s...passes with those MADE NO DIFFERENCE in my times. The uprev netted me 3/10ths (best run vs best run) in the 1/8th and 2+ mph but the shifts are MUCH harder and I now break loose on the upshifts. will keep trying.
all in all, this car is impressing me more and more. N/A 3.7 6 cyl capable of 12 second runs. BMW uses turbos, GM and Dodge 6.2 liters and the new 5.0 is just a beast.

Temperature and elevation have a lot to do with it. I'm close to sea level and usually go with temps below 60-70*F.

They might not have made a difference in the 1/8th mile, but they probably would have in the 1/4 mile. Each of my bolt on mods made me a little bit faster in the 1/4 mile but more noticeably improved my trap speed. I've trapped as high as 109.5 mph and that's without Uprev.

I figured my 650 el played a part here in central tx, along with temps and humidity.. but still! I just cannot see how a full stock 370 without bolt on mods can achieve these times!

Where were you? I didn't see you at the track this weekend:icon17:

Well I did it. Yesterday I broke 12.5. I did a 12.487 @ 109.15 w a 1.696 60'.
Next run I did a 1.681 60' (my lowest 60' ever) but couldn't get it into 2nd. :( That would have been a 12.47 for sure. Ended the day with 3 12.5 runs.

I have no idea what mods to add to go lower. LOWER not slower:).

More details on my350z.com drag section.

Race fuel would slow the car down further, unless it was detonating madly.

Race fuel = slower ignition. (Allows more timing advance or compression or boost. None of which you have.)

Best times = Good air (High barometric pressure), good traction, little incremental changes, and practice, practice, practice.

In any endeavor which I begin at (and suck at!), I always simply watch and ask and chip away at things. In time, all of a sudden you 'get it'.

Good luck!
