Mine is faster and more economical in RWD.

Think about it.. instead of engaging the clutchpacks to drive the front wheels, the front wheels just become parasitic losses. It's not going to be as efficient as a pure RWD though.

You would also have less wear on clutch components as there is less traction which means less load and less stress. I don't know about the M35's, but I regularly bounce the limiter in 1st in RWD and 4WD and the wagoon is still going strong. It constantly surprises me with the abuse she takes, just laps it up and asks for more!

Our 4WD systems are quite intuitive, while there may be only a 5% split normally, under heavy acceleration and heavy breaking the system will feed more torque to the front. So really, any form of spirited driving is stressing the system.

That said, there is a surprising amount of traction still available in RWD (I do have a fair bit of suspension work though).

Just for the record, if you are putting a car on a two wheel dyno I would strongly suggest removing the front drive shaft. If there is any electronic glitch while the drive shaft is still connected t

Thanks for that. As soon as the snow has gone and the weather improved a little, I'll be trying it out some more.

Can someone put up what it says in the manual word for word on this please? I'm interested in the particulars. I see the basics. Unplug the wire, turn ignition to on (not started), pump the brake 5 times in 10 seconds. But do you have to plug the wire in again before driving or leave it unplugged? Does it need to be done again every time you start the car after turning it off? I'm curious to try this on my series 2 rs4s but want to know the exact details first. Thanks.

Don't have my car here ATM - is there any reason to suppose this won't work on a S1 C34? Or to put it another way can anyone with a S1 confirm that they have done this successfully?

i reckon it should work cos i think the way the transfer case works the same way (shoves fluid in till the wheels spin the same speed)

only 1 way to find out tho

Sorry the exact title was "tuning in RWD" and it was a few threads down - its now top of the next page.

Yeah I looked at that too. The link in there brings you here. It's like this thread is the centre of the universe and all links lead here. Haha. Thanks anyway mate. Going to give this a shot today.

I feel I must just note to you guys that if you want to drive around in 2WD, you have to START the car and then hit the brake pedal 5 times. If you turn to the key to on and do it, it resets when you then start the car.

unplug, start the car, pump the pedal till it flashes, then drive sensibly with no wheel spin at all ph34r.gif

It only require 5 pumps but because it's working off the brake light switch (I assume), if you don't take your foor all the way off the pedal it won't register the next pump.

I don't push the pedal all the way either, enough to make the brake lights flick on is all the pump you need.

OK just ripped out the kick panel but couldn't find any such switch/plug. Pulled out a few random plugs (all with more than 1 wire) but no good.

Has anyone managed to do this on a Series 1 C34 and if so where did you find the plug and what were the colours?

In my 260rs it is a 2 wire plug, i think one wire is green and the other is black, just guessing as im 4500km's away from my car

OK and you have a series 1 and it was behind the kick panel and it worked?

Thanks

Bob

Found it !!! small black plug fastened to a bigger loom - plug has single yellow wire with green trace socket has black wire!!!:cheers:

Yep series one, yer wasn't exactly shure of the wire colors but that sounds right, did u test it out?

Yes as above. Can spin the rears now but all I really want it for is when I go to the drags (for the first time) so that I can at least warm up the rears - I am not sure I have enough power to light up all four with 255 wide tyres!

      Nismo GT Pro LSD configurations

      By GTSBoy · Posted

      Well, the trouble with that ^^ is: The configuration shown is absolutely a 1-way, not a 1.5-way. There is no way that a 1.5-way can be said to offer LSD action only on acceleration. If Nismo cannot get that right, then it is impossible to believe their documentation. That ^ is not a 1.5 way setup. That is a 1-way.   And so now I have allowed all doubts to flourish and have gone back to look at the MotoIQ video. I originally made the mistake of believing him when he said "this is a 1.5-way" at the ~6:10 mark. Because what he did was take the gear assembly out of the 2-way opening and just rotate it one place to the left to drop it into the 1-way opening. When he dropped it in there, the cam was "backwards" compared to the correct orientation shown in all other photos of that config. The flat shold have been facing the 1° ramp side of the opening, not the 55° ramp side. And I thought, "gee that's cute", but I was concerned at the time, when he put the other ring back on, that the gap between the rings looked like it was wider then in the 2-way config. And then I said a lot of things in my long post on Tuesday that could only make sense if the guy from MotoIQ was correct about what he'd done. BUT... I have now done my homework. I grabbed a frame of the video with the 2-way config, and then grabbed another with the "1.5-way" config, snipped out the cam and opening of that frame and just pasted it direct on top of the 2-way config. I scaled it so that the triangular opening was almost exactly the same height in both. AND.... the gap between the plates is wider with the cam installed in the triangualr opening backwards. That is.... it cannot go together that way. There would be massive force on the plates all the time, if you could even reassemble it.  So, My statement on the matter? The Nismo diff is actually only a 2-way and 1-way. There is no 1.5-way option in it, regardless of what they say. Here's a photo of a real 1.5-way ramp opening from Cusco (along with the 1 way option). And the full set of 1 through 2 way options from their racing diff, which is not same-same as what we'd typically be using, but...the cams work the same. A little blurry, but it comes from this Cusco doc, which is quite helpful. AND.... Cusco do in fact do what I suggested would be sensible, which is to have rings that do 1 and 1.5, and 1.5 and 2. Separately.

      Well it wasn't as easy as I thought.... and it also wasn't in my original manual which I did end up finding. They discuss the process in the Nismo catalogue though and it requires slight machining. Page 145.  NISMO PARTS CATALOGUE 2020

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I'm an idiot, my intercooler is rated for 1000hp. I had clicked on the wrong product. Knowing the delta P would be nice, but I'm doubtful I'll do it. Now as for an EMAP, that would be great and I'll get around to it eventually but from my findings in my last post, I'm considering a turbo swap now.
