Question about FC

Noticed this at my 1st NHRA race last season. What is the thing sticking out from under the chassis that looks like some kind of tube that has some sort of filter on the end? See attached pic.

It's the clutch filter. When the cars slip the clutch for the first 2.whatever seconds they are making an immense amount of shavings from the steel floaters and the centered iron discs. That tube attaches to the scatter-shield (bell housing) and the filter keeps most of it off the track. If you ever see a car lose one, it will have a black cloud following it down the track.

You don't see the drivers climbing out all covered in clutch dust anymore either thanks to that. At least not like I remember in the 90's. Force was great at turning white firesuits black!
 
I forget what year NHRA mandated the filters but go back and watch the videos prior to the mandate and you can see what a difference they make.
 
TF has these, too. I think Alan meant sintered, not centered. But I am just be anal retentive, lol

Alan, is there a fine if the filter is lost? That's a lot of clutch dust on the track that would need to be cleaned up.

There's no fine, but the guys behind you in that lane would probably stop by and kick you in the shin. Or someplace more sensitive.......
