F355 Challenge clutch cover/shield

The cover/shield/cooler is useless unless the rear clutch cover is drilled.

 

I may do the brake ducts also if the come off easy. Getting my glass station set up here at home to do some work making molds

 

Pretty sure my cover is Carbon and as far as I know it's original. I will snap some pictures and post.

 

Any special pattern?

 

I will take a look when I get home Friday. Time is tight in AZ til late sept. But. Tim, send me an address... I'll try to get it moving.

The regulation manual shows where to drill, Tim.

 

You mean the "R" word ? LOL

I'll dig out my book just saw it this morning but where


OK I cant find it would you have a scan of the drill pattern ?

 

I'll post some scans tomorrow, Tim.

Funny man....... Thanks Tim.

 

Thank you no rush at all

 

I think he may be talking of the pumpkin behind the cover for air flow, that grill at the bottom is stock on all 355's.

 

I got some pictures for you, Tim. My bearing cover was never drilled...

Ahh I see now perfect

I was thinking behind the clover it would be drilled

 

Tim,

Drilling the rear clutch cover directly behind the shield would increase the chance of ingestion of tire boogers into the clutch housing. As it is, we're constantly cleaning out rubber from everywhere they can lodge underneath the car and even in the wheels and brake calipers.

In this video, you can hear the racket they make as I'm driving down the front straight at Lime Rock Park...

Thanks Robb

I'll treat her gentle

I see an A & B version

 

Though Tim does not want to make them, would there be any benefit to having this on a street car?

 

None what so ever

They work at speed and you need to cut holes in your pumpkin to ventilate it.
It may as I have herd will help overheat the clutch in traffic.
I wont be using one on the street

 

I will be waiting for mine Tim.
Thanks

 

I also have in my possession an OEM shield that is larger then the 355. Not exactly sure what it s but doing a mold of that also

So I will have t different styles and most likely make 2 variations of each. One stock one enhanced cooling

Since someone brought up this thread,I guess I should clarify the options a bit here .


The very first clutch cooling cover was optioned only on the very earliest 355’s. It wasn’t a “full” cover. You could still drill holes on the sides of the pumpkin for ventilation. Plane jane looking. Bottom half was spray painted black. Super duper rare. I have one.

Ferrari shortly ditched the cover completely as even the second batch of “early” 355’s didn’t have them up until 98 I believe. This cover was bigger and the last picture posted by Tim. It would’ve covered the ventilation holes drilled. Considering it came equipped in a street car, it still most likely worked.

The challenge clutch was most likely designed for extreme racing conditions. It’s smaller and allowed for exposed ventilation holes. This version might have been introduced before the 98 version, since it was equipped in challenge cars from the get-go.
