Lightweight flywheel without the noise?

nameless

Sorry, was trying to clear up a misconception...
Regarding the original question. It is actually gear rattle/lash that is taking place.
The noise is inside the tranny from the input shaft not being dampened by the dual mass flywheel. This makes sense when you think about when the noise is actually happening.
You are starting from a dual mass flywheel and going to a lighter single mass flywheel. Dual mass flywheels are used because of its properties with inertia - while harder to change the rotational speed - the benefit is that the power pulse transitions are smoother essentially cushioning the noises that would otherwise create gear rattle. Going to a lighter single mass flywheel you lose the vibration dampening benefits from the mass you lost.

The best way to mitigate this is by using a sprung hub which should help dampen pulses and changing to a heavier weight transmission oil. Dont think it is a question of what flywheel doesn't cause gear lash (the answer would be OEM), but if there is a combo that people have used that minimizes gear lash. I've used OS-G & Exedy combos in my car in the past, no issues - but it was on an FD (apples to oranges, since power delivery is different).

well i have driven mine with the new flywheel and clutch and maybe the guys before me got a different unit than the one i got or they are sissy nancy boys (no offense) because i don't hear that much noise and my clunk in first gear is actually gone.

This reminded me of Ricky Bobby..."With all due respect, you're an idiot!" LMAO!!! Best part of that movie!

We have installed hundreds of clutches and flywheels over the years and we've seen some cars that don't experience any rattle while others that do rattle. We have used multiple flywheels and clutch combinations and the results are always the same...different. Basically there is no rhyme or reason. Some cars do it, some cars don't. It is something that we warn all of our customer's about.
