12.721 @ 110.05
 

Ran my personal best time today. It was the first pass on the year on the track.
Same set up as last year except i had the GTM torque converter on the car.
The quickist 7 AT with bolt ons.

60 ft..... 1.869
330...... 5.351
1/8 ...... 8.185
MPH...... 89.24
1000...... 10.634
1/4...... 12.721
MPH...... 110.05


Temp was 52 degress and the tracton was good. Launched at 1900 to 2000 rpm.
I will have the skinney front tires on next time i go did not have time to pick up the rim today.

will post time slip soon.
I ran the stock fuel curve and stock nissan ecu settings as i have not put new map in with the uprev/
It would hvae gone in the 12.5's but for some reason when i shifted into 5th the rev matching did not work and the rpm dropped to 4000 rpm from my shift piont which was 7200 today. It usally only drop's 1100 rpm. the car lost power during that shift every time.It felt like the motor stalled and then came back to life.
This only started happening after I hooked up the uprev to my car.
Need to know why this is happeniing. It's just like missing a gear. The motor takes time to aclerate after this gear change.
Other than that the car was very quick.
Next time i go i will be putting on the stock manifold taking off the Motordyne and using my cobb for tuning. The shift piont will be 7800 rpm.
The GTM converter worked well.

One happy Z.

congrats that's a good time and mph!!

thank you,
I can not wait till I put the GTM Stage 2 Sc on the car.

Hmmm. You sure the new torque converter isn't slipping...?

What is your stall speed set at? If you are launching < 2K, I'm not sure the new TC is making much of a difference one way or the other :confused:

Either way -- awesome time! Great job :tup:

You'll probably trap higher with the factory IM.

Congrats man, that's an awesome time! Makes me want to hit the drag strip again. :tup:

The reason i launch at 2000 rpm is that my tire's start to spin on the line. I have to put new back brake pad's on the car as they are taking a beating when i do my burn outs at 6500 rpm in 3 rd gear with the brakes on.
I usually launch at 1200.

It supossed to be set at 2500 to 2700 rpm.

Congrats awesome time

I found the best RPM to launch at was 1500 in the few runs I did.

Do you think the transmission PCM needs to be calibrated to match the new converter a bit better? Nice run, this makes me want to try out drag racing now.

Great time! What are you mods

Is this with full interior?

You're not selling the motor dyne manifold are you? Lmk! :)

Just when I was starting to catch up you set the bar a little higher. Competition makes us all better. Great run! :tup:

Nice Run.

Considering that there are 100 350s, for every one 370z, I find it interesting, that when I log on the 370z site, I'm never dissapointed, there's always someone posting about racing their car. Sometimes on the 350z site, it can take weeks to see a new post on their dragracing/times thread.
btw. congrat. on a great run.

Ray, tires & gears = 12.7:)

Im on 350 z site as well.
