12.942 @ 106.80 Pass Tonight with room to improve in my 6M
 

I Went to the Englishtown RaceWay Park tonight. like I have said in other threads I was shooting for a 12 second pass with my manual 370z Base No Sport package so no VLSD 370z and got it.

I used 26x10.5 M/T ET Streets and I must say these are NOT the tires I will use again. I am not familiar with slicks or the "sway" they produce without skinnes. These tires are something to get used to. I did, to an extent, but with no doubt about it I was concentrating more on the "sway" than driving so I definatly did not drive as well as I could of. I ran the psi at 18 the first pass and Let off 3 different times and still pulled a 13.2 @ 101 ... Was easily my best launch too, which was weird because it was the first pass I ever did with the slicks. I let off a few times because I felt the " sway " ( strange side to side feeling the first run but got used to it when I realized its not all that intrusive, just noticable. Def something most have never felt going 70+ mph ) ...

I upped the psi to 21 and the sway was def tamed a good bit, and I was able to push the car pretty good. When I spoke to others they said the sway is a known thing and you get skinnies for that, etc. Most just advised me to get the M/T ET street radials a drag radial instead of the taller side walled ET Steet slick I have. A ET street radial a nice and light 17/18 x 10 would be perfect to keep the cars feel the most OEM while still getting traction.

But with that aside my first run was 13.2 @ 101 ... second 13.0x @ 106 ....

and third 12.954@106.80

The 60 foot is decent, and keep in mind this is on an open diff , and I did not pull the ABS fuse so I was not able to do stand stills. I simply went around the water with my M/T ET Streets and did a rolling burnout or 2. Def not ideal to heat the rubber, I need to look into getting the ABS disabled so I can at least light them up without abs or whatever it is that cuts the fuel and dis-allows a stand still burnout.

But even with being a bit nervous about the tire situation they certainly hooked way better than my stock rubber did. A few weeks back, my first 1/4 track visit I couldn't do better than a 13.5. With 60's of 2.2 + .

The ET Streets without heating them up got me a 1.945, But a 60 of 1.94 is nothing to be proud of with these tires. I could of done better. I'm hoping I can get a nice setup of Drag Radials for next time and sell these wheels off to someone who will use them properly, because I wouldnt advise to use them with stock rubber up front unless you are used to the experience. A turbo 350z was there with the same tires with stock rubber up front too and he knew what he was doing , so its not like its soooo scary, but a wierd feeling with the slicks causing the car feel as if its floating almost.

I will see better numbers with this car the way it is with just a new tire setup. I was always driving nervous and I think shifting too early and slower than desired because of this sway feeling. That is my guess why my trap is , almost, much lower than I expected.

But all together My 370z certainly did not disappoint tonight, it ran better times a bunch of srt 8's , I lined up and beat a Z4M that was Dinan'ed out. The guy was really cool, we bs'ed a little bit, he couldn't hook at all, but I have our race and slip I will post and you will see, his car never starts to catch up. But he needed new rubber. I drooled over this car, ill post the pics.

I raced and beat a New SS Camaro ( 13.9 - 12.9 ), BMW z4m very tastefully modded (13.7-13.2), a near stock 09 evo mr by less than one tenth ( 13.155 - 13.187 ! great race )

and got whooped by a c5 with bolt ons + 100 shot... that was my first run and at 1/8 of mile i was one tenth behind him but this is the run where I let off a few times because I felt the tires acting up. ( 12.135 - 13.206 )

Im not sure as to what the DA really means but I Used a DA Calculator from dragtimes.com that uses the weather from the time of your run in a formula with the tracks elevation, etc. for DA and it was Density Altitude: 1046 feet
Relative Density: 96.97 %


I played around with launching RPMS and my best launch was produced when i was steady on 3500 RPMS after one of my better little burnouts, It hooked pretty good with just a little spin. After the 12.9 I did one pass and dumped higher and I rode the clutch wrong or whatever but it was a 2.05 60 and netted a 13.2, I was hoping for a 12.8x that last passed but was still thrilled about the 12.94 in the Manual which needed this to shed some light on the 6M doing the job of moving this car down the track just fine.


here is a picture of my car waiting and the z4m. It had wheels, monster brembos, exhaust, suspension work, dinan badges. it was nice in person for sure. He was frustrated with him times though, his best was a 13.3 with a 2.2 60 foot.

great times. noticed you posted in the 350 forum.....waiting to see how all the 350 nut-huggers take it :stirthepot:

congrats on the 12.9 and it be nice to see similar, if not better times on a drag radial setup, assuming ur keeping the radials up front.

and that z4m...wow

Yes I want to keep oem rubber up front and go with 275/40/17 M/T Street Drag Radials... Should keep the car much more stable and will allow me to rev higher in the gears up top, I think I shifted early out of fear most the time. It was def wierd with the street radial (slicks)


the z4m was much nicer in person than the pictures too

I resemble that comment ;).....but seriously....glad to see you got your 12!!! Need to find out where that mph is though......should be in the 111 area without issue.

For those of you that launch off the line out of the box...What do you rev to? I'm kinda a newbie and will be taking my Z up to the strip once the break in period is over...Just don't know what an ideal rpm would be to launch off from...Everything thus far on the car is stock to include the 19" Rays wheels and the clutch

Start at 2500 feathering off the clutch and work your way up until you find the happy median b/w bogging off the line and spin....it is a narrow window typically. It is also highly variable as different tracks and weather will lead to differing levels of traction.

what he said above is spot on for stock rubber....

I'm telling ya its low because I was not bringing it to red line up 2nd and 3rd and also was taking extra time to shift than I would all because of nerves created by these demon tires I have. Just let some time go by and I will be back with a better time and mph.

this was also only my 2nd time to the track in about 6 years time so I am still getting used to the car and deciding on the best techniques.

great time! Way to stick it to the 350 owners haha.

Thanks...Great info

Did you change your front tires ? you can not run radial and non radial tire's on your car.
I have the same slicks and skinneys on my 350, it drives straight as an arrow.
If you mix them you are begging for trouble.
Nice times.

Yea I mixed them and was begging for trouble, but never again. LOL

Im contemplating just ordering the MT Street Drag Radial in the same size as these et streets or getting a set of 18x10 like you did and go with the 18s...

Are you planning on doing a burnout Z ? If so, by pulling abs fuse or line lock or something else ?

12.9@106 is really good at DA-1046ft. its probably why your trap was only 106mph instead of 109-110ish. if you was further south down in my area you would be a 12.7 to 12.8 second car. really good times.

Perhaps I am reading you post incorrectly, but you have it backwards....higher temps +higher humidity (the south)=slower (higher DA). It's (+)1050'.....which isn't terrible. 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.

thats when you bust out this :P

YouTube - Drag Race: 08' 350Z w/ full bolt-ons vs. 09' 370Z w/ Berk HFC's

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

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

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!

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

..and that is the video that started the biggest 350 v 370 debate over at the other site.

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.
Z Eliminator

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.

:icon18:thats my video, im a f'in regular celebrity over there :roflpuke2:

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 offense either way but you're kinda the guy all up in the 370 board with the Blah Blah 13.XX ur cars arent that much beter Blah guy here ya know...

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.

if you're talking about coastal plains the best pass I've had there was a 13.25 @ 102. Thinking about trying Rockingham or Z Max.

i saw you run nice passes. i was also in the wrx on the way home my titan was pulling the blue car.

hahaha small world... vinny had said you had a 370 too... I think u missed the 12.9 though. I was trying to launch from higher and higher towards the end of the night and the outcome was 13.0 - 13.2

2700 seemed to be the sweet spot that night... I should of kept with that..

Were you driving the TT 350 ? You or who ever was driving looked to have a little trouble getting traction even with those MTs ...

What kind of power is your beast pushing ? I was expecting to see you go atleast low 12s.

Seemed like the WRX wanted to run but after a fun night racing I was trying to get locked up in NJ , lmao. He ran his car too right ?

thats Rocky's 350 i just provided the truck for the tow. i know the 350 is pushing some serious numbers with the JWT 800 series kit. we might go back out on WED night. the wrx ran a 13.6

Yeah I am talking about coastal plains. I want to try Z Max or Rockingham as well problem with Z Max is they don't do a whole lot of test and tune nights. Are you 7at or 6mt? and what all do you have done to yours?

7AT
Stillen- CBE, Intakes, oil cooler
Berk- HFC
Cobb- Accessport
NST- Pulleys

Put down 301 horsepower and 249 Torque on dynojet

What about you? What do you have done?

6mt
JWT pop chargers
Berk Test Pipes
really heavy monoblock 20s w/ 315/35r20 nitto invos on the back lol

have the stock sport wheels on the car but the 2 subs and box adding about 100 pounds. could try taking it out for one run.

If you ever go aftermarket for the rims and want to get rid of yours let me know.

301whp with those mods? wow that dyno is either reading hella low, or the Auto suffers from alot of power loss compared to the 6mt.
