HI Guys: Been lurking here for a while, but now am rebuilding a 82 GTSi that had dried out after 10 years of neglect. Great shape, but all rubber was dried out, and needed all services. So in doing the timing belts I obviously took out the right side ductwork and fender skirt. It is properly connected to the fuel distributor, but there is a smaller round connection that had no hose. The Ferrari diagrams show a flex air hose from this point to somewhere in the bottom of the cart. Where? Nothing seems obvious to me. Can anyone help and ideally perhaps send a picture of the properly places duct? And while I'm at it... She now runs great with the major done. But there is a pretty loud whistle from the passenger side probably related to this ductwork and the air intake. Is this normal? Thanks!
Thanks Mike! Super grateful for your response. No, I think that is the connection for one of the breather lines. I'm talking about the fiberglass duct that goes from the door to the fuel distributor. It has a flex air duct that is supposed to go somewhere low in the engine. It is gone on my car. I've attached a screen grab from the parts book that shows the item. I'm talking about the thing marked as #26. It is easy enough for me to get some flex hose and connect to the fiberglass duct, but have no idea where it is supposed to exhaust. Thanks for your help.

Hose 26 doesn't really "connect" to anything -- it's a fresh air vent to help cool the diff and cats. There should be a sort of sheetmetal loop piece welded onto the chassis structure to hold the far end (and point the end in the proper direction).
It seems to go nowhere but it directs cooling air to the right side axle cv joints because the forward bank exhaust runs right across them.
I rerouted this duct tube to direct fresh air directly at the alternator. Thought process was that, otherwise, the alternator would be living in a super-hot environment, with the block on one side and the front bank's header on the other. It is my understanding that this duct was added when the pair of USA cats were added, in order to somewhat cool them both. Since the catless Euro models of the day did not have this duct, I figured that I was safe from most potential differential / CV joint heat damage when I changed over to a catless and more compact Euro Ansa exhaust system. And, for me at least, so far, so good.
Thanks guys! This is super helpful. Having had Alternator problems in cars in the past, I think I'll go with Dave's strategy as I can't see it making much of a difference for a healthy CV joint. Cheers, D
After looking, I would agree. and the CV area is quite hot so I'll see what I can do, and try to find vestiges of that attachment point. Thanks again guys!
