Balance of AWD's

[gsxeclipse97]

Ok i searched but i couldn't find anything that showed what i was looking for. My friend bought a 2007 350z and he was telling me that because the car was well balanced that it would out handle my car. he said that his car was 51% in front and 49% in rear with out driver. I couldn't find the weight distrubiton on our car's but from what I remember awd cars will always out handle a rear wheel. so the question is what is the weight balance on the 97+ cars?

back on topic,

I used to have several dsm's all AWD,
now I have an 03 350z, the thing is with the Z, it is WAY stiffer chassis, and weight distro islike 47/53 or something, that engine is tucked in there,
as for handling, I have non stock tires, 20" wheels with 285's and 245s,
for high speed cornering I can whip a dsm no problem, seriously,
I had sways and full suspension setulp on my 91, and it always wanted to kick the rear out or understeer. but theres always more throttle with a dsm.

it was weird at first going from a hard hitting turbo to a NA v6, but in the end I wouldsayits more reliable, but eats gas with a leadfoot,
any comments?
btw I recently got a gxsr1k and dumped it so im drugged up1

Yea small comment there. the 1g i could see you doing that to but the 2gs are a litte better in that department. I also believe that the 1g are much more narrow than the 2g is so they tend to roll more going around turns. The 2g my car is what i was comparing it to.

I have a friend with a 350z and his car handles precisely ( far from stock )
And it feels like it can definitly out manuever both my dsms.
Its a 300 plus whp all motor soon to be turboed. Honestly though I feel there is more
entry and exit vehicle control when the motor isnt turbo charged, because the power band will tend to be more linear than in a boost applied vehicle where it can tend to have a dip, or a spike in the power band, but then again with proper control and throttle input it can also be an advantage. ( Not in all setups though of course. )[/QUOTE]

With your friend that motor is large enough to spool turbos very quickly. he shouldn't have a problem with power surge.. plus is you stay in boost you don't need to worry about that as well like if hes going on a track per say. you would just have to down shift to the right gear to put you back into boost so you wont have a lag issue. But with having almost 2 liters on both sides i wouldn't be to worried.

This is a bit off topic and may be a basic question but felt I had to drop it somewhere but out of curiousity how does the torque split in the dsm awd system work when your doing donuts or trying to drift it? Like how does it deal with those situations?

It breaks.

It breaks.

Can you tell me why it breaks from doing donuts or drifts?
And are we talking about on wet ground, or dry ground or both...

You're really fighting things to break a wheel loose- it's putting more stress through the viscous couplers than they're designed to allow. Their purpose is to go solid and not let a wheel spin, and if you have only one tire, or one end spinning, you're heating the living daylights out of the coupler, which it won't endure for long- minutes will kill it. Also the axles and drivelines are not meant for that kind of stress. The system's designed to not slip, and to have each end helping the other if it does slip.

Yea thats what I figured but rather hear it from someone else.
I just see so many videos and have seen friends spinning around doing 360s in the
rain and trying to drift in the snow in some videos, thats why I was wondering how
eminent damage would be considering a lot of ppl do it, and Ive even done 360 before
didnt think i was going to brake anything but now its good to know that the vc
cant handle that. Is this true for welded diff awd cars also? My friends gsx has a welded diff
and if he corners hard the outside tires screech and the car fish tails a lot. Since the awd system
is designed to compensate for any slipping wouldnt this still apply that the vc will get overheated and damaged
from braking loose tires all the time on a welded diff car?
Thanks for the responses.

I would have to agree with you on there I have done that on my car but the tq needed is pretty high on just a regular basis.. The last time i did it I was going 40 and tooka a 90 degree turn. The back slid out and i could feel the car trying to straghten itself out but it was a weird its not like the rear wheel drives at all.

To chyme in on this... I've done something similiar before with a little wild and unexpcted twist.

I was driving, recklessly, and launched from a stoplight. I slammed the wheel to the left and I felt the back in slowly push it's way out to the side. As I was spinning tires through the turn, I slapped the car into 2nd gear very hard.. the result? All 4 wheels hooked up and I found myself coming head on into the side of a old, smiling lady in a Lincoln. Granted, I hooked right and managed to pass by without as much as skimming her, I was about 6 inches from actually making contact. That should make a testament to how capable, and reliable, the AWD System of these cars are. They're not to be abused if you're not experienced. I learned that the hard way.

Wow well I wasn't with anyone on the road but that sounds scary... What is the distrubtion on the evo 9's if we are full time 50/50 does theres just shift around a lot so there is no way to account for it. The reason i ask is because if you can shift the power wouldn't that make the car much more responsive to demands of the driver?
