Any Gains Of Awd --> Rwd?

[TP_]

Hello!

I dad a discussion with a few friends about turning my Stagea 260RS into RWD, and if there's any gains in doing so. The idea was to remove the forward drive shaft and the fuse, there would be no harm to the central locking clutch, so I don't want a debate whether it will damage anything or not.

Performance wise, it wouldn't become a clean RWD because of the front differential etc. But still, do I gain any performance just running it RWD? it only needs to run 2 wheels, so in my world it definately makes more power to the ground, power that the fwd normally consumes?

Let say a 100-200km/h (60-120mp/h) where the 4WD start don't matter, would I see a difference in performance here?

Please, enlighten and discuss!

100hp.....

Better still sell the 260 to someone worthy and buy a commodore...

[BigBoyDan]

I'm only joking btw

[Hadouken]

It's not a constant 50/50 60/40 whatever split. Its not a evo!

Atessa works different. It's rwd most of the time, when the back slips then have torque transferred to the front.

Power loss, minimal.

Why do people like you exist on forums? is it so damn hard to stay on the topic? I had thoughts of writing something like this but thought that wasn't neccesary on SAU..: It's my f*cking vehicle, i do whatever the f*ck i want with it so please, dont tell me why I am an idiot for wanting a 260RS, but RWD.

Joking or not, it's irritating.

JoshM35; 100hp? you think I am one of those stupid persons who thinks that airfilters give's 5% more power? like "aah yeah i have this BMW M5 with 510HP, I added a sports air filter, it says it gives 10% power so now i have 561HP!!!!!! then i bought iridium spark plugs and they add another 5% overall power, so now it has 588HP. I also ordered a Supersprint exhaust-system, it adds 10% power to, so it will be doing 646HP! YEAH! not to mention Shell V-power which will add 5-10%! omfg! that's easily 700HP+++!!!!!!!???!!

Sigh..

Someone is an idiot. 260RS is RWD.

It just has a better system in place when shit gets hairy. How bout you buy a RWD stagea and sell your 260 to someone that appreciates it for what it is.

[TP_]

Josh; they probably stretch further than yours.

If you can find something that answers my question, i'm thankfull, I think I'm the first to ask this.

045HOW; Seriously, did you even read my post?

[KiwiRS4T]

Yes the awd soaks up a few kw. In normal driving its not much as 95% of the effort goes to the rear wheels and 5% to the front.

For most people the small loss of kw is a small price to pay for the additional grip which offers better acceleration. Even a bog standard RB26 can spin the rears if in 2wd.

If you want to improve your 100 to 200 km/hr time you would be better to wind up the boost a little and get a good tune with an aftermarket ecu.

The answer to your question is... there is nothing to be gained.

[joshm35]

Hence ask a supid question get a stupid answer..... Go back and buy an s13...... As previously stated sell it to someones who will appreciate it.

[TP_]

Why is it a stupid question? why would I buy an S13? I appreciate the car and intend keeping it. What is your problem?

KiwiRS4T: Thanks, that's one answer I've waited for!

My car has N1 BB turbos, HKS Hardpipe kit, Mine's front pipe, Apexi PFC, larger intercooler/injectirs etcetc. It makes 420whp/492wnm at 1.4 bars, so it's far from stock. Next upgrades would be 2530 or 2860-7 turbos and Poncams, the rest supports at least 600 engine horsepowers.

Ok well since the loss attributed to the awd is a fixed number ( say15kw ) and not a percentage then the more power you have the less of a factor it becomes.

[BigBoyDan]

Sorry if I was irritating, but yeah it's been covered before.

I'm not an expert but in my opinion you'd have a different power delivery but no real power gains. Your still carrying the weight and as you stated the front wheels are still driving the front.

Others have seen improved fuel economy but with different awd systems.

[TP_]

Ok, thank you Dan. I'll just keep it as it is then.

Sorry for me being so "bitter" earlier, had à bad morning at work .

A search turned up this guy http://www.skylinesaustralia.com/forums/topic/69626-proof-of-difference-in-power-with-gtr-on-a-2wd-vs-4wd-dyno/page__p__1288143__hl__2wd+or+4wd+on+dyno__fromsearch__1#entry1288143 who says his car (GTR) gets 50kw more on a dyno in RWD. That sounds a bit high but thought I'd mention it.

There wouldn't be too many Stags in Sweden, would there?

[BigBoyDan]

All good.

'about' 50kw? The dyno wont show the front wheel resistance

[iamhe77]

If you are that worried about weight, maybe look at a CF drive shaft?

[zei20l]

far out there are a lot of bitches on here!!

i ran my M35 (yes different car, but same principal) without a front drive shaft for about 3 months.

it 'felt' lighter, and was a little more deliberate coming into corners, less understeer. and best of all, it was a little better on fuel!

there is always drivetrain power cost, so removing the front drive would probably make your car a little faster, but without the AWD grip - as already mentioned.

its a 10 min job to remove the front shaft, just do it. if you dont like it, put it back. simple

[KiwiRS4T]

Or if you want to try it out you can just do this (I can confirm that it works on S1 as well as S2):

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

In my S1 Stagea its a very small black plug taped to a loom with a single yellow wire with a green trace going to the plug and a single black wire going to the socket.

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.

You need to do this every time you start the car.

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

Andif you plan to do this a lot you can put a switch in somewhere.

In the 260 it's a big green plug with two wires, near the bonnet release. Make sure it's a constant flash and not a solid as that's an error
