On a cold late fall/early winter day the DA can be 1500 to even 2000' lower than that, but at the same time in the dead of summer it can get to over 2500' on bad days.


would you like for me to post the DA of the track near me? 3 weeks ago DA of.. drumroll please...... DA -300. lower elevation trumps humidity(always) if you think 1050 is a good da i feel sorry for you. heck even atco which is in NJ has negative DA's all the time because of the low elevation.

Sorry, but that's incorrect.....-DA's are rare even on the east coast. I've been in the game for a long time. Thus far in 2010 here we have had........0 days/nights with DA's under 0 when the track has been open (Cecil/Capital/Mason-Dixon/MIR). These are tracks around 100' in elevation (except Mason-Dixon which is 600'). Temperature isn't much difference b/w Cecil/Capital and ATCO/Englishtown. Only time you get - DA's is perhaps in March (not this year) and early Nov-Dec (maybe late Oct farther N) if the track stays open that late in the year. Can you have an oddity day under 0 in April/early Oct.....sure, but it only happens once or so every other year. I don't doubt you had a stray day in Ark under 0, but to say "all the time" is totally false for our area.

I was out testing my tires last night and i can spin then at 2000 with the brakes on. Now the tire preasure was 32 psig. not sure what will happen at 22 to 25 lbs tire. It was very odd because the ecu did not kill the moter, when i tried this. It usually does.
I have line lock on the 350z but not the 370z. They say that the mickey thompsons drag radial do require a burn out. Im going to go around the water box, back up to it and do a brake stand burn out and go to the line. I have a 7 AT, so this will not be easy to do.
Im, not sure what to do as im lucky if im going to get 3 pass at the track tonight.
You ran some nice time's

Solus 05-07-2010 09:34 AM

The track here sucks... no glue etc. I usually launch between 2k and 2.5k. Best run here so far for me was a 13.35 with a 1.91 sixty foot on Nitto NT555 (not 555R) 285/35r20s. I got my Invo 315/35r20s on and am going to the track tonight hoping for a 13.2 or better :D

chuckd05 05-07-2010 12:00 PM

Solus are you Auto or 6 M ?

and good luck tonight Eliminator!!! Looking foward to atleast a 12.7 .... but with new tires maybe some trial and error needs to be done before you get your launch how you want it, but good luck!

Solus 05-07-2010 12:19 PM

I am 6 mt... cant wait to see z eliminators results tonight.

The Z goes up in smoke tonight!!!!!
The weather here was terrible it rained all day .
There was a 2 hour window at the track and i desided to go for it.
They tried to dry out the track and they let us race on it.
It was 42 degree's and the wind was againts you at least 25 miles an hour into the nose of the car.
There was only 7 cars there and one of then was a white GTR.
My dream come true. to finally line up with a GTR and see how fast they are.
This is my first time at a big name track and its the first time racing at night.
Everything went wrong. Too much gas in the car.2/3 of a trank
My ecu would not let me heat up the tire's. it kept stalling out the engine.
The best i could do was floor it out of water box and spin then close to the start line.
The weather conditions got worse every run as there was no prep on the track at all.
My first pass was an earth shattering 16.613 @98.11 with a 2.6 60 ft time. I did the 1/8 in 11.38. It spun the tires through 1st, 2nd and half way through third. I hit the rev limiter at 8100 in 1st and 2nd. It also fish taled on me at the gear changes. ( not a good feeling) There was no traction any where on the track.
I thanked God that i survied that run with me and the car in one piece.
I foolishly decided that i should make another run, ( the storm was coming and the wind got worse.
I took the tire down to 20 psig had my best run of the night, 13.099 @ 110.02 with a 2.121 go ft time. it did the 1/8th in 8.502 @ 87.16.
I can not belive how the 305 35 18 drag radials just spun in 1st gear. I tried every thing for rolloing the car at 750 rpm and them feathering it but my times got worse and worse,
And now for the main event The 370 vs the GTR. we got into the staging lanes and they shut down the track as it was too dangerous to race because the rain had started to sprinkle down. his best pass was a 12.3. he never showed me the time slip but i do not think that he went that fast. The car would not hook and i learned a good lesson tonight that a non preped track in 42 degree outside air temp is a bad thing to race on.
I feel bad as i have let the 370z guys down tonight. I could not imangne have a GTM Sc on the car tonight as im sure i would have hit the side retaining walls with the loss of traction. The only good thing about tonight is that the motor sounded wicked in side the car the intake temp's were 46 degress acording to the cobb.

Im so disappionted at my times.
But warmer weather is coming and i will try again. It was not the night to drag race, i learned the hard way. For all you guys racing in cold conditions be carefull as its not worth it for you could lose control of your car and have a bad acciddent. I had one scarey moment when it spun the tire's at 8000 rpm in 2nd gear, and it spun when i shiffed into 3rd. i will never race in these conditions again.

chuckd05 05-07-2010 10:31 PM

Ahhh, its no big deal... 46 degrees your engine would love but def not the tires... That stinks though. Def happens. 16.6 lol

I am going with the 16 inch radial with the taller sidewall yet skinnier tire to attempt to get traction.

Z Elim, I looked at our ABS fuse under the hood and it is part of a series of 3 fuses in one plastic holster. And with one being the vvel I was not about to mess with it, Is that the same way the ABS fuse is in the 350 ???? I'm going to buy another fuse before I mess with it, and possible try to disable the one ABS fuse by cutting the current fuse, Than if that allows me to do burnouts I than will some how solder a wire with its own inline fuse with a switch to turn ABS off for burnouts at the strip.

Zeliminator....with any drag oriented tire....sidewall height is more important than width. There are an absolute ton of cars that go 9's or better now on 275/60/15's. Going to have to drop the pressure down to 15-16 and really heat 'em up with temps in the 40-50 degree range with that short of a sidewall. I am sure you will get it dialed in.....

Red370....my only issue is your attitude in posting...I have no qualm with posting of your vid, etc.....I think this HR vs VHR thing is pretty silly. All that being said.....you only ran like a 13.3X in that vid correct? What would people have thought I had I beat you by the same amount and posted it up? Just sayin'......the results are arbitrary and highly dependent on driver skill/experience.

I didnt post that video, someone else from here did, I didnt post it because i knew it would turn into a flame war as it did. I dont post there anymore because the maturity level there is laughable. But congrats on being the first 12 second 6MT Chuck!:tup:

No, I'm really not. I posted in here because Chuck and I had a running dialogue through PM, etc on my350 and I wanted to give him props for his runs. I just don't like the way red370 handled himself in the my350z thread. In fact...I was the one that initially posted that I expect to see some 12.4-12.6's out of bolt-on VHR's. The other 350 users didn't like that too much. I'm past it now.
