Obviously better tires = better 60' times, but the fact is that he's not even close to maxing out the tires he already has bought and paid for. Why would he go buying new wheels and tires when the ones he has right now are perfectly capable. You're seriously recommending that because his first ever pass down the drag strip was a 2.02 60' that he go and purchase a new set of wheels and tires when what he has is capable of pulling 1.6s without too much trouble? Better driving (more experience) is worth way more in this case than better tires will be. If he wants to step up to an even stickier tire then that's great - it could help in the long run if he becomes a serious drag racer, but he's far from tapped out on this current setup.

the problem here is 122 mph , he is picking up 27 in his last 1/8th which means to me a really bad first 1/8th and the car driving itself at the end to a good mph for how bad the start was. with the correct tire size plus the correct driver, traction should not be an issue. more seat time looks like the answer here. picking up 8 more mph on the whole track is where he should be and that could take months....

I disagree. I can pull virtually the same 60ft times on my 18inch Drag radials that I do on my 15 inch M/T et street bias plys. My tires aren't what is keeping me from a better 60' now, it's my manuals trans, power level and clutch.

Those M/T ET street radials are PLENTY of tire for his setup in a 6MT 350Z.

yeah but with the same power levels and REAL tires, we are pulling mid 1.5s, so that is what he is talking about. mike has a very fast car and lots of drag racing experience, he is NHRA licensed and his car runs high 8s. he drives it all around and to and from the track.


when he says better tires, i am sure he is referring to slicks and not drag radials..

Well, im sure you know the track plays a huge role on this. This trap can be perfectly fine assuming the DA's were high.

You east coast guys should try checking out our SoCal tracks; the differences is so big you might start to think somethings wrong with your cars as compared to the east coast track performance.

To the OP, what were the temps? Not sure if you already posted this info. If they were the usual temps of Summer, with your 1500 ft elevation, you can easily see 3500+ ft DA's, which won't help at all

Huh?? I have no traction issues whatsoever on my DRs. they don't spin AT ALL. The JWT clutch in my car and my power level was the only thing keeping me from coming out of the hole harder last year.

Um...ok...my ET street bias plys ARE basically slicks....so what's your point?

Thanks Jeremy. I knew you'd understand what I meant...
I believe I will bow out of this thread.
Congrats again on the 11 second run :-)

Are those what help you cut a 1.7 60'? Could you have cut better 60' times on slicks?<------ trick question!

Because w/ your old power level you could have gone 11.00 with 28"-29" slicks.

AJ cut 1.5's on 29" slicks w/ 470hp/500trq which is a far cry from 1.7 because thats almost .4 off the ET.

Hell, going from a 245/60/15 26.5" Hoosier drag radial to a 275/60/15 28" Mickey ET Street radial cut my 60' from 1.77 to 1.65 and thats w/ only 360hp/ 410trq.

We can only speculate how this guy is launching. But if the guy is launching at 5000 rpm's like he said he is, and the tires are letting loose, then its a tire or track prep issue.

I've cut a couple low 1.6s on the E.T. streets and there was ZERO spin. The limiting factor seemed to be my JWT clutch slipping a bit on the hard launch.

Pure speculation.

I disagree...traction was NOT the issue, and I don't think a taller slick would have been beneficial at my power level unless it eliminated the shift to fifth gear which has nothing to do with my 60'.

I had 430rwhp/410rwtq @ 9psi and ZERO weight reduction on my car and still pulled low 1.6s pretty consistently. Seems like his power advantage and especially torque advantage played a big role here. Not the 29 vs 26 inch tires.

One pass on two different tires is hardly evidence of an advantage from the size difference.

He's made ONE pass in the car for god's sake. Let him get some more passes under his belt before we tell him that he needs new tires. I don't even think he did a burnout.

Nealoc187

No one misunderstood what you meant about better tires meaning better launches. All I'm saying is that the dude has made a single pass in the car and you're advising him to ditch his current setup because his 60' wasn't up to par - after one single pass.

Are you the one that owns that lemans sunset turbo that I've seen driving around town?

<EDIT> Just looked at your profile...I guess so...

Yeah that is me, should be anyway. As far as my launch goes I definetly need more seat time. The 17inch radials I have, ill wait until i burn those off before i decided to change to a different size. The tires when I ran were so cold it didnt even pick up little ricks to sling everywhere like they should after i run the 1/4, so the burn out is gona make a big difference for me on my launch. Also for those who have ever ran at Bristol know it is about .3 slower than other tracks. There are alot of guys that take there cars around here to different tracks and get anywhere from .3 to .5 faster 1/4 and up to 5mph more on there times. And most the tracks they take there cars to are very close to sea level, so that helps too. As i get to take my car more down the track ill keep posting on how i run.

Not meaning to get off topic, but do you still have your carbon fiber hood on? I've seen another lemans sunset Z with it's stock hood and the front bumper missing that had a large intercooler in the front of it...looks great btw for the few seconds that I got to see it.
