Default My clutch dampener is gone

And good riddance! Also ran Motul RBF600 through the clutch line and my clutch actually feels like a clutch between shifts. No more annoying lag between redline shifts.

Sure:

Dampener on the line:

Dampener itself:


The dampener is not a valve... it's a restrictor. The clutch line internal diameter is "X" size, but the dampener internal diameter is "Y" size (about 2/3 smaller than the clutch line). It's a 2-way restrictor: engagement and release. As you can see, we just put in a simple coupling where the dampener was (internal diameter on the coupling is slightly larger than the ID of the clutch line) and now I get full hydraulic pressure to the slave. Clutch definitely has a bit more kick to it, and no more annoying lag. Clutch doesn't seem to heat up really bad after hard redline runs through the gears.

Yes it's in the driver side fender well. I have a friend at a transmission shop that's got a friend at the Nissan dealership across the street. He mentioned that he had a Z guy with mods wanting to delete the clutch dampener and the Nissan tech knew exactly what he was talking about right away and supplied him with a few different fittings. We didn't get the exact thread match in the fitting, but as you can see it threaded onto the male connectors just fine (nice and tight) and no leaks (pic was after we bled the clutch line checking for leaks).

Bad idea, you'll destroy the flaring and it won't seal tight. The coupling we used had a flare to match the clutch line, just with a larger opening so it wouldn't restrict the flow like the dampener.

What pedal pulsation? I don't feel anything though the pedal -- in fact the pedal feels a lot better with the Motul fluid and dampener gone. Clutch definitely feels better now as well (mind you I have a new clutch/pp/flywheel from Nissan since they replaced my original leaking slave cylinder).
