:iagree: on stockers?? :tup:

Just got back from Portland International Raceway:
2009 370Z Sport Package
7 speed auto
Bald OEM Bridgestone Tires
1/2 tank of gas
Fast Intentions Catback
No other mods of any kind
13.08 @ 106.43
Backed it up with a 13.09
Temp = 64 deg.
Elevation = about 30 feet
Hard to launch without lots of wheelspin.

I was thinking the bald tires would act like slicks, but wrong-o, they spun bad into 3rd gear on two runs (not the runs mentioned above). I never could get close to full throttle in first gear. I one foot drove the car. I used my right foot on the brake and stepped over to the gas, rather than 2 foot driving, when you have your left on the brake and right on the gas. Traction control off, manual mode active and paddle shifters used. I feel totally confident that less gas in the tank/better tires (slicks, or at least some tread)/better driver (one who isn't making payments on the car!) could get one to run high 12's. I'm quite sure. I can't recommend lowering tire pressure. It didn't seem to help me, it did set off the TPMS light, and might even have interacted with the ECU to reduce power. Hope this helps.

Congrats on the Run!

Dont think the TPMS will reduce power output, I have lowered pressure before with out any side effect. I cant wait to go see my new times at the end of the month!

I went to the track tonight, made 5 passes. There was a 2 hour 'break' to clean up a mess from a bike. http://images.ibsrv.net/ibsrv/res/sr...thumbsdown.gif

The DA's were about 1700 most of the night.

My best times tonight were:

13.657@102.7mph w/ 2.11 60'

13.675@102.2mph w/ 2.03 60'

13.759@102.9mph w/ 2.12 60'

I might have had a 13.4x or 13.5x pass but missed 3rd gear (I had a similar 330' time when I ran 13.495 a few months ago). http://images.ibsrv.net/ibsrv/res/sr...milies/doh.gif

Otherwise a fairly disappointing night at the track, but I'm gonna try to go back next week!

I'm pretty disappointed. With all the mods and tune that I have, I only managed a 13.5 @ 105mph tonight. That was with a 2.0 60' time. Stock, I trapped 103mph.

Just keep at it, Ryan!

Made a few runs tonight at the local track...

best run was:

13.493@103.91mph
2.09 60ft
DA = 1435

It's finally starting to cool off here! I normally trap 102.x mph but towards the end of tonight I was trapping 103.x mph.

Wow. I'm still stock and I went to the track for the first time this past Wednesday 2.38 60' (wheelhop) 13.5 @105.5. 6spd. How do u guys deal with the wheelhop? I really dont wanna break anything.

Tell me about it...I'm not a very happy camper. My goal was to get the car in the 12s NA. Yeah, that's not happening!

And its not my driving capability...I had over 180 drag passes in my old G35. I managed a 12.2 out of only 350whp.

In regards to wheel hop, try lowering your tire pressure. My car had baddd wheel hop Thursday night at the track. You just have to play with the throttle a bit.

504 370z, what track did you go to?

You should go post on the South Louisiana thread in the southern region of the forum. There are a few of us who like to go to the track occasionally.

+1 on the tire pressure. It helps a lot with launching. I run about 25psi in the rears and 40psi up front.

WTF?!? you went to the track ... i have no missed call....grrrr

Its all about your tires and tire pressure... I ran 12.95 and average a 13.0-1 most passes.. With a 1.95 60 I got 12.95. You can get a better 60 than that too so I have room to improve.

Gears flywheel clutch headers all still left to do. These cars can def hit 12s n/a just takes practice.

Forsure i run 21psi in the rear and cut an average 1.90 to 1.94 60 fts on the re050. ime shootin for 1.8xx on the re-11's. oh here comes 12.5xx's.

Chuck have you thought about swapping back in your original springs?? you know you will get better weight transfer.:tup:
