hey all, just trying to wonder what the awd system of the stage is based on? (s2) so r33 setup

is it a mechanical diff or electrical diff?

torsen, viscose etc setup???

from what i know and have been told, it stays in rwd until it feels that the rear is exceeding its torque output and to stop it from slipping it will engage the front.

or is it just clutch driven??? clutch is disengaged until it feels slippage etc and then presses clutch together to connect the front wheels??

at the rear of the gearbox is a 4 or 5 row chain that wraps around the exit shaft

the chain runs into the transfer box where it meets the front drive shaft

between the shaft and the chain is a series of clutch packs which are designed to slip al little (a bit like an auto box) when some power is needed up front, the pump adds pressure to the clutch packs and some of the torque/power is transfered to the front wheels

the max power to the rear is 100% and when the clutch packs are fully engaged the torque split is 50:50

Thanks for posting this info up. I was also wondering how the drive system works.

Dunno what you'd have to be doing to get 100% driveto the front wheels or 50:50 as you also called it. Even "popping" the clutch at 4000rpm while rolling in 1st gear with my brass button exeedy clutch makes the gauge for the front drive move a lil bit.

aaaah, this is pretty cool. sounds interesting, may google more

I ran it through Google as well (on between load 200ton trucks at work) and found some great info on it on Wikipedia. There was even a video on it! I will be having an indepth look as soon as I get home.

Its a bloody awesome drivetrain. The Japanese are bloody Clever!

Max power while the system is operating normally is 95% to the rear. This is why you can't just pull the fuse to go in to 2WD mode, there is a procedure and it works, 100% RWD.

The system is pretty much based on the R33 GTS4 system, runs 5% preload to the front and splits more torque as it feels it's needed.

Another truck driver or a loader driver at a mine? I drive container trucks - mere 45 tonne max!

Yup. I work in a coal mine. I operate the smallest Digger there which weighs 300ton. Most of the others are 600tonners and the largest 2 are 1200tonners... Those babys can dump 100tons of dirt on a truck in one scoop! :D

anyone got the link to that rwd procedure (the one that you can leave the front driveshaft in)

I have posted it up a number of times...

But here goes again..

Locate the "air bleed" wire behind the drivers kick panel, it's a plug with a single wire either side (usually green socket, white plug).

Disconnect it.

Start car. As key comes back to the ON position, within 10 seconds, depress brake pedal 5 times, 4WD light will start flashing to indicate you are in 2WD mode.

To go back to 4WD mode, turn car off, reconnect plug and off you go.

I have hooked mine to a switch in the centre console.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.

      Strangely I noticed it either disappear later in the day, or not be present. I definitely noticed when I was crawling around that open wheel thingy entering the pits (that part was audible in car). Driving home and commuting around town for example, I didn't hear it. It's plausible that it was a brake disc or something still slightly in contact. The brakes absolutely felt BAD for the first couple of sessions, huge amounts of shudder and grinding as they got up to temp - And then I actually just forgot about it as the day went on/didn't notice it. The videos were from the morning when this was more present than the afternoon/drive home when it wasn't. I've asked around and got a variety of responses including handbrake shoe contacting hub, CV joints, CB tailshaft bearing as above, and clutch input bearing. I didn't test if it disappeared when clutch was in. I haven't noticed it in any of the other videos nor did I notice it when driving to that extent. More or less hoping the microphone at the rear license plate giving some kind of clue of 'something' but it looks like "spin stuff and see if you can notice it" is the way forward here. I could be smart and use the gopro mic and re-mount it to that location to see if the sound is still present at low speed actually. Sounds like a decent test whenver I have the CBF'ness to drive the car again. Given it's almost 40C for the day of the track day and the next 3 days after, the CBF is high. All I've done since getting home is unpack the car, remove the remnants of the lip and undertray and left it there. I was surprised how well the PMU Club Racers actually worked. The brake performance on the track was absolutely fantastic, best I've ever personally used, no fade whatsoever and the bitiness was almost too good, I was scrubbing more speed off than I needed to, but I also ended up infield when I started trying to scrape off ... less speed.... so...

      R34 GTT idle problem

      Not really, no. Anything you would do is easily reversible.

      I would like more noise related info for my truly uneducated guess  Does it do it at idle or when revving, clutch engaged, and disengaged? Does it only do it when the car is moving? I've heard "similar" noises from a clutch pack that left the chat room, and CV joints that have chewed themselves out But as Matt said, how's the yokes, tailshaft and centre bearing going after their last little issue Fingers crossed it is something simple  Weird noises make me cringe

      By silviaz · Posted

      One other question, is there a chance that changing the idle speed can lead you down a rabbit hole and is the reason the tuner didn't touch it? Reason I ask is because if that's the reason the tuner avoided it then I probably shouldn't be touching it lol.
