It's about tires for the drag strip. Three tires were tested: performance street tires, drag radials, and slicks.

What interested me was the performance street tires, the SCC testers got better 60ft time and 1/4 time(not sure of this, can't remember)when they have the street tires at 30psi and didn't do a burnout.

I haven't posted a thread about how I'm getting such bad times when I went to the track. I couldn't figure out why my first initial run was usually my best. Maybe for street tires, it's best not to get them heated up too much. Even though I did do a small burnout in my first run, since it was the first run, the tires weren't really that heated up. After that, each time I made a run, I would do a burnout. I usually do the burnout for a few seconds, maybe a bit too long. I didn't go through the water box by the way. Anyway, any of this make sense?

I'm running on stock 15" wheels with 215/60/15 Bridgestone RE950 tires.

Anyway, it was a very good writeup IMO. I didn't read the whole thing, so I forgot what brand of tires were used. The car was a turbocharged Sentra I think.

 

Mickey Thompson ET Drag bias-ply tubeless slick, BFGoogrich g-Force T/A Drag Radial, and Falken Azenis Sport all-around performance tire. that sentra was friggin' sweet btw....

 

Street tires get slick when you do a burnout in the water box/burnout box..

 

i didn't do a burnout when i got my 2.16 and 2.17 in my 2k2 but i did have like 18 psi of tire pressure. when i did a burnout i got a 2.29 but i think that was more due to bogging off the line.

Hm...you're right. I had a hard time getting traction after doing the burnout. So even if I don't go through the water box, if I do a burnout, the tires would get slick? That make sense. Something to think about the next time I go to the track. My best 60ft. was a 2.2x, IIRC I didn't do a burnout out then. I guess I didn't figure that by doing burnout it would hurt my time.

 

There is a difference between a burn out and a quick scratch to get the rocks off. I do just the quick scratch on my street tires and it seems to work best. The first few runs are allways awefull. After a few runs the tires get heated up from the runs any way so no need to burn them up.

But the biggest factor to me is learning the launch. No matter if you go to same track or not the launching pad will allways be different. Thats why I will do a bunch of initial back to back hot laping runs, so I get a feel for how the car is hooking up. My launches usually get much better after about 5-10 trys. You cant expect to go out to a track and blast off a super launch the first or second run, it takes car abusing practice to get it right.

 

run 1 2.17
run 2 2.16

i got lucky though and i know it.

Let me the next time you head to the track again. I want to give it one more try. If I still don't do good, I'm done with racing.

 

hehe..it's gonna take more then just a couple trips down to the drag...you just have to continue to do it until you get it right..
there's no short-cut...

 

I'm just kind of torn between whether I should even continue racing or just give up and go show. After all, I have a freaking automatic. I'm thinking of getting NOS, but not should if it's worth it. I haven't heard of any automagic Maxima hitting 13s with NOS other than Don. Opinions?

 

i KNOW i would have had i had a little traction but nOS get expensive. 40 bucks a week to fill that tank the way i was using it. 14.2 at 102mph HAS 13's written all over it esp with a 2.5 60foot time. i just needed some drag radials bad. i was i kept that car for another couple months and ran it once more. oh well i'll be in 13's soon enought.

 

I have yet to make it to the track. Maybe next week? I have never raced at a track(I have raced though a few times). I have had 3 5spds, 240sx, 3rd gen max, now 4th gen. So I am pretty good at launching. What should I expect to pull 1/4mi? With my mods minus the amp, subs, and spare?

 

if your good and it's about 50-60, high 14's ish.

 

True. After getting the kit and all the accessories, it will add up for sure. I'll still think about it though. Mainly, I want to get it and use it on the track, I don't race on the streets anyway.

 

you say that now but wait till you feel that rush of 100ft and over 100ft lbs of tq at teh flip of a switch. i used it coming home from the mall.

Street tires perform best when they are cold. Drag tires on the other hand only perform well when they are warmed up. Doing burnouts on a street tire releases oil from the tire therefore making the tire slick. All street tires need is a "scratch" to clean them off. If you can't go thru the water box, then you'll have to spin them a little longer to get the water off.

Too bad I don't know this until now.

So, if I'm on my first run, I just do a short burnout/scratch to get the rocks off, do I need to do it again each time I go up there? Or could I just simply go straight up to the staging line? Thanks.

 

I'm not sure if it applies to drag racing, but for road racing I know street tires don't need warming up...in fact, you don't want street tires to build up heat like you would with a competition compound tire since street tires begin breaking down very quickly. I'd imagine this would relate with drag racing also so I'd assume a burnout with street tires is unneeded if not harmful towards your times. But like I said, I'm talking about lateral traction and not straight line traction so please correct me if I'm wrong.

 

I didn't bother to read this whole thread but I'll say this, my best 60' times have been without adjusthing the pressure at all from where I have it on the street, and of course no burnout, I never do burnouts. Only if I am getting unbearable wheelhop do I start fiddling with the tire pressures.

 

Maybe luck, maybe torque. 2k2s have the torque needed to pull this off. I bet 2.0's are attainable with practice.

 

ya i'm sure they will on a good track once i get to one again esp with my tires now. i got a 2.29 on my 3rd run and that was with a bog i thought the run was over but i pulled back hard i couldn't believe it.

On the vid, "island07"( http://www.maximaproducts.com/movies/ ), I did what Mardigras described. I don't do 10 second burnouts but spin the tires enough to get the sand or gravel off of the surface of the tires. I was able to get 2.28 in my 60'.

 

Its seems everyone except me and Don downs themselves for owning autos. Please!!!! I was still able to hang with modded Maximas in the Pike vid and I gave a lot of 5 speeds a good run at Island Raceway. I have an auto and don't even have a VB adjustment either.
