What's the reasoning behind the diff and box breather tanks?

What's the reasoning behind the diff and box breather tanks?

Both blow fluid out of them at high speed.

I think it's a g-force / high revs / left hand or right hand corner thing.

[No Crust Racing]

I'm interested because my box seems to be pissing oil out of it but it has a new extension housing seal and only seems to weep from there (Silvia boxes seem to always leak from the extension housing).

I thought maybe I'd over filled it.

I assume it's coming out from underneath the boot around the shifter, the rubber one, not the interior one, and running down the box.

My Diff is fine though and is sealed, I don't recall my 33 having any way to leak from the diff?

[ssxRicho]

Both have a breather port.

Standard Nissan:

The diff has a hose that runs up into the chassis rail near the rear right wheel.

The gearbox has a hose that runs to a hard line high up near the bell housing.

Both just vent out to atmosphere.

I'll have to check, I didn't think mine did and I certainly didn't disconnect anything when I had the box out.... maybe that;s the issue? I am talking Silvia though.

Thanks for the info though.

Google says I'm wrong which will likely be my issue

I get the same from my Silvia, although mostly used on dirt the g forces aren't as bad so its not so much of a problem. From what i was told its to do with the box not having enough baffling internally and a lot of the oil rushes to the back of the box and ends up being pushed out the shifter.

Really enjoyed reading this thread too, awesome work and impressive times.

Hey mate, will you be driving at NSW Time Attack?

Hey mate, will you be driving at NSW Time Attack?

Yep, sure will be.

Just waiting for the entries to open now.

I'm working on a new rear wing setup at the moment, not sure that it will make much difference at Wakefield though, all that is for Eastern Creek later in the year anyway. I have a theory that the 265 AD08R might work better than the 285 AD08R around Winton and Wakefield though.

So before we trek to Wakefield I'll do a Friday test day at Winton to get an idea of the impact of the new rear wing setup and gauge if there is a performance different between 265 and 285 AD08R at Winton that data should translate well to Wakefield. I have a 7kg spring to try in the rear for Winton/Wakefield, currently running a 10kg which works well at Phillip Island/Eastern Creek.

I have spoken to Forced Motorworx about my gearbox woes. It's a pretty cost effective fix to replace the synchro clips, so I'll get the box out over the next couple of weeks and get it down to Forced. Much cheaper than destroying another selector and ko'ing another gearbox, should have done this last year.

I'd like to change up the front splitter for something more sophisticated than the ply I'm currently running as well. But I haven't come up with a better design to get air to the oil cooler without altering the front bar design.

Awesome. Myself and a mate will be competing as well in clubsprint - though much slower then you lol, we are doing it for the experience more so. We will be in a silver 33 and 34.

Sweet! More RB's the better

I think both the Power Tune GTR's will be there in Open Class as well. Will be a great weekend for Skylines.

[No Crust Racing]

I'll be watching your splitter progress, I'm thinking about V2 myself.

How high does your current design sit off the ground and how are you going loading it onto trailers?

Yea I've heard they will be there, will make my times look even slower! Lol.

Will be good to meet and put a face to name

The current design is removable, so we take it on and off each time.

I want to keep it that way as well, just makes it so much easier.

On the k-frame we have bolted some 25mm tube, on the splitter there is 20mm bar that slots in.

There is some 20mm tube at the front of the spliter and on the sides.

It's quite low to the ground, unsure of height.

I'm talking Tony with Little Red into coming as well. So there will be a couple of Vic 33's invading.

I might have to redesign mine.

Yours must be lower if it clears the swaybar also.

I had issues with mine attaching to the cross member after upgrading to the bigger swaybar. Bar pushed the splitter down and bent brackets (stayed attached though).

Yeh it's below that. It's as high as I can get it using the k-frame mounting method.

I have a tilt trailer, but would need a fancy hydrolic thing if any kind of splitter was to be fixed mounted.

[No Crust Racing]

I use two stage ramps I made that the splitter clears and are long enough that the wheel hits the leading edge before the next "step".

Making it easily removeable might just be easier.

Hope you get the gearbox issues sorted so you dont have to rush changing a box like last year!!! Same problem as last time?

Any idea when entries open? I thought i may have missed it

They opened last night

Same problem I've always had with them. The clips fall off and come out in the oil. Cruchy for a while then, the selector fork breaks sometime after.
