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.

      Shoota's R33 GT-R RB30/26

      By Shoota_77 · Posted

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      Cleaning my wheels 😍

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!

      Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.

      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.
