Weber 40 IDF’s for The Ghia

[carguytroy]

Apparently there’s a Weber carb shortage due to COVID. However I think a I found a dual 40 IDF kit but it lists it’s only good for bug and bus. Is this because of the air cleaners? If so I’m just going to order them and find a shorter air cleaner(s). Any other reason why they wouldn’t fit?

another variable is the manifolds. some are a bit tall and some are offset (in a good way) I haven't fitted 40idf's specifically, so I'm sorry i can't advise on the best combo so you can keep the deck lid springs and fit the aircleaners in.
but i have stuffed 48 IDA's with air cleaners in and made it work so I'm sure you will have success

Hi,

Yes should be fine. I did this recently.

I got CB performance offset manifolds.

This gives plenty of room for the air cleaners. See the below Pic. I think I'd even have room for the much taller ones.

See below pic:

That looks good. Do you like your twist linkage better than the crossbar?

Hi,

I tried some bigger air filters today and they do fit. But when you close the lid they are only 2-3mm away from the springs. So it's pretty close but fine. They look much better than the cheapo ones on before.

The springs fold up when you close the lid. So if the springs touch the air cleaners when the lid is open, they will clear when closed. No need for struts.

On my ‘70 the left spring didn’t touch but the right one did. Enough to deform the filter. I removed that spring for a time but eventually went with shorter stacks and filters. This was with 45 Dells and CB offset manifolds.

I havent purchased the velocity stacks yet either. I was wondering about those and the short air cleaners. Probably need the shortest stack they make for these

I never understood running the lower profile air cleaners. I thought the reason for adding dual carbs was to get more air in and more power after all.

You can buy these or make a set of these as well to use the taller air cleaner:

CB has some short stacks and the 2 1/2” air cleaner elements. They don’t seem to have the tapered stacks for 40’s. When I got my short tapered stacks I got them from Dellorto UK as CB didn’t have them then for my 45s. They do now but not for the 40s.
Shorter stacks will lose a couple of horses which might be measurable but it’s nothing I’ve noticed driving.

An alternative, Berg sell the bracket/prop circled although it would be easy enough to make one.
