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! DAN

I went to the track tonight, made 5 passes. There was a 2 hour 'break' to clean up a mess from a bike.
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). 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.

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.

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.

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.
