Hi guys,

If we remove the 4wd fuse (gtr34 v-spec) to measure the rwkw on a 4wd dyno, what will affect or damage to the drive line??

In normall driving condition (without torque split), is it true that the gtrs are running permanant on 25% front and 75% rear power??

Any explains would be appriciated, CHEERS !!!

no gbox damage will occur. as for the 25/75, take the fuse out, go out on a quiet road, and drop the clutch at 7grand. if it slips and then grabs, well, you know...

COOL !! that's a costy way to test but !! hehe

Any way, while tuning my car on a 4wd dyno, the 4wd and a-lsd check light came on together but we didn't know how to fix it. So we decided to run on rwd mode. As I noticed, it ran like a 100% rwd (front wheels didn't move) and when we let go the accelerator, the front wheels started to catch up a bit. Now it smells like a clutch burn (in the transfer case possibly). I wasn't sure where the smell is from, because i dripped some oil while doing an oil change before the dyno day.

So, what do you reckon?? the smell is from the oil that I dripped or from a burned clutch?? it's been a week already but the smell is still there.

cheers!!

You can't pull the fuse on the R34 GTR, that trick only works on the R32. You'll need to drop the front drive shaft to run it on a rwd dyno, doesn't take long, 10mins....

ya smokin ya clutch packs mate, and it will smell like a wood fire burning pretty much as i had a local workshop think they knew what they were doin and did exactly the same thing. smoke come billowing out the shifter hole into the car as a result of about a 5 sec run up on the dyno.

take the front drive shaft out that connects to the front diff and u will have no problem. its about a 5 min job and 4 bolts to remove is all it takes.

i smelt my clutch packs burning for about 500km after that as they must have got really cooked

if ya in perth i can recommend a shop to never ever let touch it

ouch!! that hurts !!! I shouldn't bring my car there in the first place...dame!!!

Mate why are you taking risks with your car like this. Take it to someone who knows what they're doing. Leave that workshop and never return.

but hang on. The 4wd check light was on, that means the torque didn't split at all. Doesn't it mean that the car was performed on rwd only??? and we ran it on a 4wd dyno (not 2wd dyno) in the rwd mode(no torque split). This way , do we still have to remove the front drive shaft?? and it was strange that it ran like a 100% rwd car when we rev up...
