What did you do with your Z today V (ON TOPIC DISCUSSION ONLY)

That's what I'm worried about - the installation really is simple....but are you sure it's done correctly? Because that part is anything but simple.
There shouldn't be any whine from the diff. When you think about it, while normally rolling forward, there is virtually NO change anywhere - the pinion contacts the final drive, which rolls the whole unit, thereby turning both axles equally fast forward. The LSD is not working here at all - there's no need for it to work.
So if there's noise....well then there's either incomplete tooth engagement, or incorrect backlash or preload.

Anyhow, if you're happy with it, all good. I don't mean anything bad by the above.

Is the LSD 1.5-way or 2-way? Does it come with the break in period? It might be a good idea to swap the oil after a thousand miles or so, just for peace of mind.

I greatly appreciate your input. Im no expert in this stuff. I will drive it around more and if I notice more whining I can bring it back to them. He told me he checked preload and backlash. He said he made a vid on his phone of the process. So I can show you guys and get your input.

Not gonna lie. You are making me nervous. Taking away my excitement. But, its all good.

The shop I took it to is Full Throttle Performance in Rancho Cordova. Looks like they are specialist in Nissan and Infiniti. He is the same guy that installed my Z1 anti starve kit.

I think Wavetrac is 1.1 way. I dont know exactly. Maybe someone can chime in with the info. I would guess its similar to Quaife. As for break in, there shouldnt be any. But im taking it easy for the first 300 miles.

Wavetrac is a mechanical gear type, not a clutch. This type of diff is also called a Torsen (Torque sensing) with Quaife being one of the bigger makers.

in general a torsen will send power from inside to the outside in a corner through the gear mechanism, but it relies on both sides having grip. If one tire does not have griff it will not lock at all and is an open diff

Wavetrac has an added design that counters this (Google, there are diagrams) so that even when one wheel slips, there is still some lock and power will be transmitted to the wheels.

It does not lock as hard as a clutch type, but requires much less maintenance and doesn’t need a diff cooler. This makes it above open diffs, OEM VLSD, or a quaife, but below a clutch type in raw power. It will also be quiet
