If you want to burn rubber, build a street car. Why waste a 30K truck? Maybe it's just my age.....

I'm old enough to know better (57), but when I go to the dragstrip to race my motorcycle, I would like to run my truck a couple of times, and would like the best 60 ft possible, besides, I paid for it.

That is awsome rholland. I can just picture it. You pull up with your bike in tow, unhook it, and run the truck!!!

I have done that, but not with the Titan, yet.

Well if you guys are racing then you don't want your tries to spin.

Maybe some of you have low air pressure or VDC on. When I want to spin I just hope in the cobra!!!

I have lite the tire up a few times so I don't know any other reason why some of you can't do it.

sounds like a dodge HEMI commercial, lol.

With Big Tow SE 2WD (and two resonators) I can spin the tires a little from a standard stop (same VDC on or off) and have done this accidentally many times with no load. I know I can spin the tires much more with power braking because I tried it the first night I bought my truck (hard to resist trying that when I had been driving a 175 HP Passport for nine years). My truck spends little time in 1st gear even when accelerating slowly. My rear tires are at ~39 psi without any load.

I believe your theory concerning the traction control is the main reason some can roast them and some can't. Whether the truck has the lower ratio rear end gears or not shouldn't make a difference with as much horsepower and torque these engines are putting out.

My theory is that some of us have a bit "looser" tolerances in the programing of the traction control than others. On a different, but somewhat similiar topic, some owners have stated they can't powerbrake or spin the tires at all with the VDC switch in, whereas I can smoke'em up irregardless of the VDC switch positioning. As soon as my system detects front tire rotation then it shuts the fun down but if I'm not moving than it doesn't care what I do.

Back to the traction control system though I think it's probably going to act differently on each truck just by virtue of tolerances...

i have a LE with tow package and i spin my tire off the line from a complete stop and when i turn the vdc off i can spin them even more.power brake is no problem etheir.not that i care to burn tires anyways i've done plenty of that in my younger days.now all i care about is gunning it and flying off the line without burnning tire and looking in my rear view mirror and seeing the hemi, ford, tundra, what ever still spinning tire's trying to catch up to me*********ha ha

I forgot to add one more thing to my previous post and that is my overall disappointment with Nissans decision to use the brakes as a traction control aid. If we all had a limited slip rear-end, we wouldn't be having this conversation about not being able to roast them, we would be talking about where's the cheapest place to buy tires.

If you want to have some fun spinning the tires just take a right hand turn at a dead stop and mash the gass. I promise that the thing will rip loose. Just watch the slip light blink on the dash . Everyone who I let drive the Titan I have preform this move. They all comment on how well it launches but I know the electronics are hindering the mahem.

Potroast · 08-18-2004, 10:28 PM

any rwd vehicle will do that. Anyone that has driven a rwd vehicle probably won't find it too impressive.

I noticed this when I started driving trucks (after always using fwd vehicles) and I found it exciting. All my friends did too -- but showed some truck guys, and they were like "so what?". Just kinda how it is.

After realizing that it only impresses ricers, and it kills your tires REALLY fast (I got 20,000 miles on my set) I decided that I should limit myself... 1 burnout per day is sufficient, lol.

I do not have a VDC switch but I do have the "s-slip”? light that will flash on the dash when the wheels spin when the road is wet. My concern is that my truck has a lack of power by not being able to break the tires loose on dry pavement. If the traction control was preventing the tires from slipping on dry pavement then why would they spin so easily on wet pavement?

It's good to know that the VDC works well.

The winters around here are hellish. I see people spinning out and sliding all over the place(usually into each other) on the mountain passes. Guess I'm going to make sure I get a VDC equipped 4x4 truck.

The traction control can only do so much to prevent wheel spin. It has enough grab from the brakes to hinder your dry pavement burnouts, but with a wet surface, of which has a much lower coefficient of friction, it can be overcome as you've noticed.
