y does the car pull off to the side when the tires are spinning? on 2k2 auto se at least

 

It's called torque steer, and it's because the drive shafts are not even in length (and the fact that your car has exceptional torque for a FWD sedan).

 

Maybe because of the torque I'm guessing, but not sure if it's enought to notice. Torque does tilt a car. Ever wonder why nascar is always "go fast and turn left" and not "go fast and turn right"? It's because of the torque. The cars would fly off the road it they turned right due to such a high amount of torque.

 

what???

 

I hope this was sarcasm....

#1) NASCAR cars are RWD (RWD=NO torque steer)
#2) The "go left' refers to the direction in which they drive on the track (counter-clockwise on an oval)

 

The reason why fwd's vehicle pulls to the right is because too much power is applied to one wheel, at the driver side creating wheel-spins due to lack of traction. Unless your car come equipped or optioned w/the HLSD (which split the power to both front wheel and minimize the effects), high torque engine power will make itself known on all fwd's vehicles, period.

 

There is still a lot of torque steer with HLSD

 

yup, but still better than not having it at all. Rear-wheel-drive and all-wheel-drive are the two solutions to tame the beast!

 

No I wasn't kidding about the Nascar thing. I saw it on some video in tech. class talking about the way the engines work. I think it was when we had an ITT rep come to our school. I mean why no go clockwise on the track......they can't....not at those high speeds with that much power. You guys probably think I'm bull ****ing but I'm serious.

 

Perhaps because of the left side driver seat?

 

So why do INDY cars turn right as well as other race cars? They are all rear wheel drive. I would have to imagine that it is the way the suspension is set up. If you look NASCAR vehicles lean to the left. I think your statement is inaccurate. Provide facts and I will change my opinion.

 

Wow, you scared me for a second. I thought you were serious

 

Well I can't provide hard facts, because it was by word of mouth by a represenative from ITT. I thought the same thing about the indy cars, but indy cars don't go as fast around the turns. I know it seems a little far fetched, but the guy sure did make it sound truth full. Try to research why Nascar goes counter clockwise. That may help. Who knows, I'm tired of argueing my point because I don't have much to back it up.

 

just some torque steer...

you can buy a LSD to reduce the torque steer but won't be able to get rid of it...try Phantom grip or Quaife. even Stillen is selling Vitek LSD for 95 and up Maximas, which is essentially the same concept as the Phantom grip.

 

You got a lot of torque under your hood.. You car will pull if you floor it no matter what. I know how you feel.. I'm SC and if I downshift to 2nd forget about it. If I don't hold the wheel with two hands I'll fly over to the next lane. I'm hoping the pr mounts and quaife that I'll be getting next week will help out.

 

What about Watkins Glen?

 

My guess about the Nascar thing is this: Think about when you see a bracket car on a dragstrip and notice that one front wheel will come up higher when they floor it. The engine torque is basically twisting the whole frame. Perhaps with all the power of the Nascar vehicles, the torque helps keep the right side front tires on the ground more.

Just my guess,

What everyone told you above about torque steer is correct - Maximas (esp. 2k2 / 2k3) are applying a lot of torque to the front wheels.

But, the torque steer on my 2k3 was exceptionally bad (car would pull when ANY throttle was applied), and I found out one of the tires had radial pull. Swapped the tires from side-to-side which fixed the problem - now the car will pull a little when flooring it, but drives straight otherwise. Note that if this is your problem you can fight Bridgestone on their warranty - I didn't bother since the problem appears to be solved. To have this checked, you can go to a Bridgestone dealer (have to find an actual Bridgestone joint, or presumably Firestone) - they are the ones that have to check it for warranty anyway.

P.S. NASCAR goes faster than Indy cars do on an oval like Indy? Do the banks at somewhere like Daytona allow faster speeds for a full-body car than the freakin' javelin-with-an-engine Indy cars?

 

You get torque steer because the passenger side half-shaft is longer than the driver side half shaft. When torque is applied to the shafts, they wind up like springs. The amount of wind-up is proportional to the length of the shaft. Therefore during hard acceleration, for every degree of rotation of the differential ring gear, the driver side wheel will rotate a little further forward than the passenger side. This pulls the car to the right. This all snaps back into proportion after the excessive torque is removed.

 

Bottomline: The VQ35DE motor is NOT a good setup for FWD applications.

 

haha.. That nascar thing was funny... In Australia stock cars go clockwise around the track. It has nothing to do with being on the other side of the world either! It has to do with which side the steering wheel is on.. Nothing so do with forces at the diff...

Why do you think we drive on the right side with the steeringwheel on the left... Imagine all the accidents if everyone drove on the opposite sides!

Get the VTEC option. That should fix that pesky torque steer right quick

 

Jeff's right, VTEC will fix it. I had a cup of coffee that was made via VTEC this morning.

 

lol ever seen that video with that honda with the custom cow paint job and the V-TAK motor?

 

I may be wrong but I think understeer and not torque steer is the reason NASCAR vehicles go counterclockwise in the USA. The driver is seated on the left side of the vehicle which throws off the balance of the vehicle by approx 150-200lbs to the left side. Indy cars on the otherhand have the driver centered in the vehicle and the overall balance of the vehicle is more centered. There is an article in this months road and track about the 350Z that mentions this during testing of the vehicle in the skidpad, it ran pretty good counterclockwise but displayed more understeer going clockwise.

LOL yes! That is the best video ever! The camaro guys are yelling at him and ****! lol its a classic!

 

I guess you've never watched CART at Michigan, IRL at Atlanta or you're just BS'n

 

Exactly!

 

I wonder if anybody here goes to the drag races. Doesn't anyone notice how when a RWD car launches that the left wheel comes up first ?? Or that the car wants to roll over on it's right side ?? WILDMANAL has the correct points. BUT -- I don't think (or remember when I road raced} that torqueing motion makes that much of a difference. Some racers have made their engines rotate opposite to take advantage of the torque while turning left on round tracks.---- Didn't help much. + kind of expensive. Indy cars can be suspention tuned to go fast left or right. And for those few times they do road race, the suspension is changed to accomplish that. e.g. spring rates would be even left and right. So why do they race on ovals turning left ?? Probably because it started out with cars that the driver sat on the left side. -- I think --

 

I'm not much of a Nascar fan but I have seen them run on road courses numerous times (someone mentioned Watkins Glen - they have also raced at Sears Point in the past). The reason Nascar races run around an oval (along with IRL) is so that their fans can sit in the stands with a beer in hand and watch the cars go round and round.

If you want to watch some real racecars, watch F1. Hopefully McLaren and Williams will pose more of a challenge to Ferrari this year. There is nothing like the sound of a 3.0 liter normally-aspirated V-10 producing 900 horsepower at 20,000 rpm. And they turn both left and right!

 

u got it dude i still think ferrari is going to win tho
schumacher is still a good driver and didnt depend completetly on electronic aids to win last leason

nascar is real boring, tho all the cars do is go around in oval... not exciting

 

OMG!

Quicksilver said it right, its the unequal length driveshafts and non-central placement of the transmission. Hondas and VW's have centrally monted trannys and equal length driveshafts, this is why they dont torque steer. But, there isnt a FWD honda or VW that can even touch the maxima in handling and accel (yes even the W8, i tested one and was thoroughly disappointed). As for wildmanal's torque theory, thats about as correct as a hamster is smart. The maxima's engine is mounted transversely, therefore, the torque of the engine makes the car rock forwards and backwards and really has no bearing on the handling.

PS: Stock cars turn left because when they invented the sport, they just decided to run the cars around the tracks that way. Had you done your homework, you'd know that the rotation of the engines in those cars actually unbalances them in lefthand corners.....this is why some teams run cheater engines that spin the opposite direction to balance cornering force.

Sorry for being so longwinded, but damn......

 

Heh heh...this thread is still going strong, I see...
