GTR on a Dyno, only rear wheels turn ?

[ix9]

Mkay, someone explain this to me.

I was watching Mario's GTR on the dyno video clip, and noticed only the rear-wheels spinning... I would have thought ATESSA would have detected no traction under the rear wheels and engaged the fronts ?

Can someone explain this ?

[Morgs]

He has just about everything on that thing.. it'd be something like a Electronic Torque-Split Controller with which he can control distribution power power between front and rears.

[gtrken]

Yea, that or he pulled the fuse.

you can't just pull the fuse on 33's but 32's on the other hand.

[gtrken]

oops, haven't seen the vid. Assumed it was a 32.

You're correct, it is a little harder.

He probably has one of these:

You too can have rear wheel drive on your 33 GTR. Just speak to Merli:cool:

That said, the car is now being re-stripped and having the entire electrical system re-wired.  We can now remove all items that are required to be road legal, such as intrusion bars, doors, glass, air bags, seat belts and the various computer assisted controls that are no longer required (such as ABS, ATTESA and HICAS).

Maybe I'm being naive, but the idea of a GTR drag car is to use all FOUR wheels to deliver power ?

How would removing attesa be good ? It's just a 2wd GTS then!!

[CamGTS]

I'm pretty sure (although my knowledge of this is limited) that with it is in permanant 4WD with probably a bias towards the rear.

[DriftR]

hmmm well im pretty sure he would have a diff system controlling it, as morgs said.

why would he use the stock one when he has the cash to get better

Just look at VL's.If you have sticky enough boot's and good sup setup I guess you don't need ATTESA,it's more weight to move.Also those 1000hp GTR's in japan only in 9's and the VL's are up with them.My 2cents.

What fuse on the GTR R32's?!

I would love to be able to put it into full RWD for a bit... just to see how it handles... <_< :lol:

they handle terrible, but spin the wheels ok!!

there really meant to be 4wd and obviously designed like that..

and with regards to the dyno run, they probably pull out the front drive shaft, only 4 bolts underneath the car, to dyno it it. (if its a 33) 32s, just pull the 4wd fuse link.

If this is GTR700, i'm fairly sure that it has some trick arrangement that allows it to split up to 100% of the drive to the rear wheels. I think it also runs an air shifted liberty gearbox.

<{POST_SNAPBACK}>

But would there be a lack of traction under the rears? The wheels are still turning the rollers?

The would not be lack of traction at the rear, but the large speed differential between the rotating rear wheels and stationary front wheels would make the ATTESSA system think there is a lack of traction and redistribute the power accordingly. Does that make any sense?

too hard obviously, not difficult to get those transfer cases smoking the clutch packs now is it. just visit gtr specialist workshops B)

woah!! welcome to the past... today!

Im far from an expert but there should be a cam shaft or something you can unbolt to make it RWD.

[fresh]

yeah u must be far from an expert, the cam shaft control the opening and closing of valves to allow air into and out of the engine, then have nothing to do with ATTESSA

the shaft your are tihnk of may be the front drive shaft which goes from the transfer case to the front diff, yes as is mentioned above can be unbolted.
