Anyone too?
yes the gear mesh seems a little bit on the tight side and you can even feel the gear grinding each others. However, the diff is not tight at all. I have checked with other V1R with the LSD and they are the same.

You need to match the gears with floating blocks. My LSD is not tight at all.

By the way White Cat...you have the 1/5th site for reference?
I found the link from here: http://www.rev-up.co.uk/index1.html

What is inconel?

The tolorance of the gears and floating blocks is not 100% perfect. Some gears are tight in a particular floating block, but some are loose. If the gears and blocks are matched before installation, you will get a perfect LSD.

so you need to buy extra unit for your master matching???

No, it is just 4 gears matching with 4 floating blocks. If they can't be matched perfectly, you may need to get an extra unit. Sorry!

Inconel is an nickel based alloy, much harder than that of titanium...and of course much more expensive too... It is normally used in aerospeace industry or the higher end of automobiles we have on our roads... I was working in the aerospace industry once as an engineer and this material is way too familiar! Maybe I'm wrong!

Yeah...mine is loose too...as if I had no oil at all in the diff... but my question is whether the floating blocks are supposed to "float" up and down the bevels? If not, why are they not "fixed" blocks? Still doing my little experiments at home to understand the working... very very different from the Kawahara negative diff!

I also don't know why the blocks are called floating blocks. Kyosho should have call them friction blocks or something similar. Those blocks never float!

This is how the Kyosho LSD works. LSD is to control the different rev of both left and right wheels. It doesn't lock up when both wheels have similar rev. When both wheel have different rev and the difference is up to a certain point, the bevel gears move at high rpm and generate heat. The bevel gears expand and lock up with the floating blocks. In the mean time, the diff feels like having some heavy diff oil. When the bevel gears slow down, they become cool and the friction is gone. The black oil is used to control the temperate of the bevel gears from being too hot.

WC, dont make thing so complicated, think about it when you have a steel metal expend to a visible size, you probably melt down the diff case. the floating block's function is to lock with the small bevel gear when the bevel gears inside the diff has spin to a certain speed. i.e. it called floating block. the theory is the same as the oneway bearing.

Hey, just tried out the LSD up front! I'm telling you guys out there to get this! Acts like a one way in corners and provides a powerful punch out of corners! Moreover it doesn't spin off like the one way! This baby is more than sweet!
But it rather pricey though....

The name "floating blocks" is kind of misleading since those blocks only provide a locking action for the expanded bevel gears. The blocks are fixed inside the diff case.

Shoot! You mean I put a oneway in the rear??? Should I put it in the front or rear?

You mean the LSD works better in the front?

So are you running the regular gear diffs in the rear? If so What weight oil are you using for the rear? Or are you running a Solid Rear Axle in the rear? Also Have you tried running the Kyosho LSD in both the front and rear Diffs?
