Default Noise after clutch instal

Hey guys, did a mantic 9000 twin disc clutch this spring on my own. Been driving the car like this as i havent had time to wrench on it.

Heres a video of the noise.


The noise goes away by either pressing down on clutch pedal or just pushing the shifter forward/pulling backward(without depressing the clutch or engaging gear) just some forward or backward pressure.

So im wondering what it could be. And also, i still havent gotten around to installing the Tick Master.

Thanks everyone

We told you that's just how twin disks sound normally. If you don't like it, I have some special clutch oil that I can sell you, but it will cost you 99.99$ per oz. It will last approximately 30,000 miles and your clutch will be as quiet as a library.

Totally normal for a dual disc. Try letting the clutch out slowly. Helps on the trucks I fool with.

Right....


Why would putting pressure on the shifter stop the rattle??

Because you're forcing your synchros to produce friction (read BURNING THEM UP) trying to stop the turning force of the engine to get into gear. The torque tube shaft is what's actually making all the noise.

700rpm idle sound way too low on that cam and cant get smooth idle. I would rise it atleast to 900rpm, that would also make car shake less and clutch not rattle so much.
