DRAG WHEEL/Tire setups

What's your 60'?

Slicks helped me a bunch over same tire as yours. Also your wheels are too big & you have very thin/little rubber to work with.

I also want to go to Atco, bracket racing...if it doesn't rain.

Z&I

Thanks for the post ...
Am looking to do the same ...
Trying to find out more re the 19" M/T's
Currently have 20mm spacers as well ... possible fitment problems ???

What wheels and slicks are you using ?

Thanks,
Bob

Still Learning How to Drive

Like if you're willing to change front & rear wheels/tires at the track or you would rather get a set of drag/street radials (rear only) & just drive to the track then just drive back home.

Now I believe you're super charged with apx. 500 h.p. What trans? gears? suspension?

It would have been better/easier if you learned before the mods. Anyway need more info.

Friday night or Sunday at Atco, I might go for the last time. My concern is rain on Sunday & both days will have very high humidity.

Z&I

I've been building the car for about 3 years now...just get that need for speed every now and then if'n you know what I mean.
Love to do quick little pick ups here and there when it's safe.
Mostly rolling spurts from 2nd, 3rd, and into 4th...backing off at about 110 or so.
It was my dd up until this past year.

Used to race when I was a kid ... when a 15 second 1/4 was a really really fast time...Corvettes, GTO's, Hemis, and Super Sports were running in the 15's and 16's.

Got the urge to track it a few weeks ago and am now on a mission to eventually get in to the 11's

Best run at Island Dragway (NJ) was 13.02 @116 mph with a 2.0 60'
The other runs were 13.1 @ 115 ... never got under 2.0 60' times

No traction and had to nurse it until I was able to shift into 3rd because of the wheel spin and hop...not fun

Track temp was in the 40's...(summer tires ... ugh)

Did as much research as possible ... and a lot from this site ... not too many Z's around here.

Came up with the need to further research the ABLS and yaw sensor and the effects it has on 1/4 mile.
(?) It is my understanding thus far, that the ABLS is not disabled by turning off the VDC and will pulse the brakes during wheel spin.
Verified this at Broadway Performance Speed Shop - by attempting a controlled burn out and hitting the brakes after releasing the clutch and creating the spin.
The rear wheels went in to a stutter mode when the brakes pulsed.
The ABLS seriously inhibited the ability to do a burn out.
I guess this is why the drifters don't like the ABLS



The Z is a Base/Sport and has:

6MT trans / ACT clutch

Stillen SC'r with a little over 8 lbs. of boost

PPI Long Tube Headers

Quaife LSD - 4.08 final drive I believe (I should know but I don't) ... will have to double check on that one though - installed within a few months of the SC'r because of the traction problems even back then.

HKS exhaust/cat delete

Custom Tune by John Nouri - Broadway Performance in Passaic NJ

Stock Suspension - not lowered - Almost 57k miles on the car now
Don't know if it's time to replace it...has seemed to be OK

Stock 19" Rays with 285/35/19 Michelin PS II's
I do have 20mm spacers all around though

Am considering the GTM Race Logic TC with launch control as a means of stabilizing and standardizing the launch...
Not intending to rev it till it sputters and pops tho' but rather give that extra bit of buffer during hard acceleration.

Any and all input on that would also be appreciated as well ...

I do have an extra set of 19" OEM rear wheels and the next logical step would be to Slap on the M/T's ...
The M/T's are a bit taller by about a 1/2" and have about 3/4" wider sector width than the PSII's.
The 20mm spacers were a good idea at the time ... :-) ... made the PSII's look good ... hence the fitment question.
Would like to avoid having to change the wheels at the track tho'

Thanks,

Bob

Wait till early next spring(new radials may come out) go to a site like JEGS. Check out street/drag radials from M/T, Nitto, & Hoosier & anyone else that may offer something by spring.
Also find 2 wheels, only two in the 17"-18" size by apx. 10" wide. You can race with spacers in the front. As far as the rear, Jegs can help you get the right offset/size to fit your car, w spacers or without. Weld wheels was my choice for the slicks, but they Jegs can help you.

Get a good rear set up that can be put on your car hours/days before you go to the track. On that day JUST drive to the track with those tires/wheels on, & the stock setup in the front. If you can get a front brake lock-up system or I think you can just remove the rear brake fuse??/ then all you'll do is drive to the track, have a cup of coffee, pull into the water box first, lock front brakes & smoke the rear tires till a bunch white smoke appears in your side & back mirrors. The starter will also wave you to go forward to the starting line. Part of their job is to tell you when your ready. Lift the clutch & floor the gas at apx. 4,500 to 5,000 something rpm. Experiment. You should be able to do 1.5 to 1.7's 60' times & very good 1/4 ET's.

Not much to do at the track & do great times & have fun. Good luck. Also it sounds like you have a very nice setup....

I did that when I stated with my 08 z. If you go to dragtimes.com, browse, hit Nissan 350z. I'm on the first page(bottom) Someone made a video of my run with the exact set up I just mentioned. I didn't even hear of forums then. Soon I was told that the run 12.9 put me in the # one spot of 350z.com. I didn't know or care at that time. Had stock wheels/tires in the front....

Awesome Reply !!!
Will check out your video fer sure.

Will check out the rear brake fuse ... does that disable the ABLS only ?
Will look in to the Line Lock.

Also need an education on the IRS and perhaps do something with the suspension while I'm at it.
Can you point me in the right direction here too?

I'm still stuck in the days of purely mechanical race cars and Traction Bars...a lot has changed since then!

All this new fangled electronics stuff has changed the playing field !

Again thanks for taking the time to reply - it already has helped me out a lot.

Bob

Still learning after all these years

Z eliminator

I have line lock on the 370z. Its a pain to install, you need 2 soliniods.
I installed them into brake compartment under the hood<
Getting the proper fitting is very difficult.
I had custom hoses made up.

Hey Andre ...
yep ... I'm a older guy ... LOL ... might have a year on you !
Thanks for your posts...
Did try to view your video on Dragtimes but couldn't find it ... is it still there?

In the meantime, I have been busy:

Already had the M/T DR II's on order (before reading your post) - they are now on the car and they do make a difference.

Fitted OK even with the 20mm spacers ... enough clearance but they do stick out beyond the fender...looks kinda mean.

Did go with the GTM Race Logic traction control - that's also installed but GTM didn't send the instructional CD with the package so I don't have the Launch Control set up.
Was able to figure out the basic settings and did a few preliminary tests.
Race Logic does work well and is a whole bunch better than the VDC.

Need to read the instructions once the CD gets here - and a little more time to get it dialed in tho' before taking it to the track.

Weather was not good this weekend so hopefully it will be better next weekend.

Will let you know how things go - it definitely hooks up better - but you still need skills to get it right.
