Questions about NSX clutches and flywheels

[burbel]

Is a clutch and a flywheel inherently linked together? I was looking at moving to a slightly stronger clutch with a lighter flywheel, but was wondering if I could mix and match the flywheels, or if they are inherently linked to the clutch?

Does anyone have info explaining this relationship?

Thanks!

They are not permanently bolted together if that is what you mean. In general, it is possible to mix and match clutches, however, there are two exceptions I can think of when this can not be done.

1. special compound clutch (ie. carbon-carbon) that have the same compound pucks embedded into the flywheel. Due to this, the flywheel would not be interchangable.

2. clutch setups that have the compound sweep or contact area in a different plane or stepped level (ie. Comptech Powergrip clutches)

Maybe it would help to explain specificly which clutch/flywheel you are looking at.

Well, I was thinking / planning to get the short gears + 4.235 R&P, and figured that doing the clutch at the same time would be easiest.

I like what I've heard about the Exedy clutch, but would like a very light flywheel - from what I have seen, I was considering the Dali Featherlite Flywheel.

Just wondering if the two could be put together or not.

The Exedy Twin Plate clutch has a proprietary flywheel, therefore, it cannot be swapped out for another flywheel. I actually think that the clutch is already light enough. 29lbs for the entire clutch, which is 5.5-6lbs lighter than the stock twin plate.

Just checked the weights from a few sources, it looks like the Dali setup is 27.x pounds, and the Tilton carbon/carbon clutch is 12.x pounds.

I was hoping to get more weight savings that that, but I'm sure the money could (will) be better spent elsewhere...

To make the proper decision regarding a clutch, you need to look at what application it will be used in. If you are replacing a clutch for a NA NSX (mostly street), then the benefits of the Exedy clutch will not be as "worth it" for the money. If say, you were getting a Comptech, BBSC, Turbo, etc, then the problem of torque capacity, heat dissipation, durability comes into the equation. This is where the Exedy Clutch shines.

It has a very high torque capacity combined with a light pedal pressure. It is also the only clutch available for the NSX that has a ventilated mid-plate for heat dissipation. There are a variety of unique features of the clutch that only can be appreciated in person. If you are attending NSXPO 2002, then you can see for yourself what the clutch is all about.
