Smoke coming from gearbox when on Dyno

Was on a dyno the other day and the wierdest thing happened.

I dont usually dyno the car in rear drive as its usually always tuned on SAS four wheel drive dyno. This time was an exception.

The car has previously made 440HP at all four wheels, so i would have expected over 500 RWHP. The car ramped up to 1.3 bar and at about 6000 rpm smoke started floating from the gear shif boot. I thought this was strange so cancelled the run at 455 rwhp. Went again for the second time and the power went up to 471 and then dropped off with more slight smoke again.

The smoke smelt like gearbox oil, but there was absolutely no gearbox oil to be seen on the ground or anywhere. Checked all fluids and everything rosy. Only just recently i thought that it might have been something to do with the wet clutch pakcs in the tranfer case, any thoughts?

Has anyone had similar problems running BNR32 gtr in rear wheel drive on a dyno?

By the way, i wont be putting the car on another rear drive dyno, its not worth the headache or the stench of burning oil!

      Duncan's V37.......race car?

      OK, solid mount Z1 diff brace is in, pretty straightforward, it picks up 3 diff hat bolts and ties them to 2 support bolts on the subframe. Pretty sure someone else on here said they had reduced axle tramp with this but mine was already pretty good for smooth wheelspin, and still is....will see you this goes over time and whether I end up with a broken rear diff hat

      Ah yes, but the part in my hand was actually painted and fitted by me! I knew any front lip was likely to be sacrificial but I've had to fix it twice already... by the time I buy a fibreglass fixing kit, sort out sandpaper blocks, buy some fibreglass filler, body bog, spend the time and effort for a 'Greg' result... a new one being $290 seems like it's the better way to go and spray that with bedliner/raptor coat and we're all pretty again.. Would have preferred it last more than a month though. Them's the breaks I suppose.

      I find it funny that the USA is finding out all this really really weird stuff, and people from the USA are coming here treating it like gospel, yet, all the info on solving those issues is here on these forums for the last 15 odd years... Also, I know how much heat it takes to ignite the hood lining of an R33 skyline. I worked it out myself... It also took a LOT of time, and heat for it to do it... Big single, and I needed to drive the car, so retarded the timing off to "protect it". Yeah, that was a bad move for cruising on a freeway with only 15 degrees of timing on it. That was a lesson I learned around 2009. So that's over 15 odd years ago. Aligning water and oil, that's identical for any turbo engine, it's not Japanese specific. If a shop doesn't know how to make sure the core is rotated the right way, then they shouldn't be touching any turbo engine. That's not a matter of "We haven't had Skylines for that long here"...

      Sounds like it is rotational in the driveline. CV? Tailshaft CB? Also.....didn't you just pay to have that bit painted and put on the car?

      R34 GTT idle problem

      By GTSBoy · Posted

      Yeah, when I dialled my idle down, given how much time I spent idling at the lights in traffic on my daily commute, the effect on overall fuel consumption was absolutely noticeable.
