air box for dual carbs

Does anyone run an airbox set up for dual carbs??

Something like the CSP set up??

My car lives outside 24/7 and I have always had trouble over the years with popping and farting, blocked jets and the sort.
Anyway - I made up a sheet that blocked off the vents on a late deck lid. A bit of light plastic that hangs down and effectively covers the filters when parked.
I have number plate and tail light cut outs so heaps of air is coming in.

Anyway - since doing this for the last 3 weeks, it has been pissing down at times in Sydney - and not a pop or fart. Perfect.

So - my troubles is definitely water related and I need to make up some sort of air box for my Dells.

Do filter socks protect any better for water??

Hi

A guy on here with a Baja made some sort of air box using Commodore air boxes I think, it looked like a good idea.

You could fit turbo tops to the air cleaners and run a pod on each end or run into a central box.

Didn't Barls make one from an Excel air box aswell I seem to recall.

I started making one from the stock Beetle air box to shut the induction roar from my old webers.
just needs a second 2" outlet on the bottom and ducting to each side.

Are you still using IDFs?
the turbo hats you can get for them make excellent air box connectors.

Bizarre ·

Yeah, still running DRLAs.
It isn't the noise, it's the water from living outside.

Going to try and get some turbo hats and go from there.

Yeah - only looking on my phone at the moment bu it looks like the CSP set up.

Would like that but really can't justify the price.

Thanks - that is exactly what i was thinking
I have flicked him a question or 2

Wondering if anyone knows what the box is?
Looks like a 1600 but the intake seems more rounded??

The oil vapour hose connects in a different spot on my Beetle air cleaner, however that would be easy to change, so I reckon it is a Beetle one

Joel ·

Its a stock 74-76 Beetle one, just facing arse about with the snout removed.

Bizarre ·

yeah - it was the lack of snout that threw me

mmm... have to start having a play

Joel ·

It's similar to what I was building but leaving the snout with a functioning preheat flap setup intact.

Hi

Maybe you could use a twin carb Kombi air box?

Craig Torrens ·

Barry, I have a 76 airbox if you need one

narumi ·

the idf i pulled off of alfa romeo 33 has the 90 degree bend hat thing that goes to
the center filter box like your previous post.
I have a set in the shed but never bothered trying anything

Bizarre ·

There is some reason the Alfa box doesn't work.
Or so I have been told.
Think it has to do with the "tops" going the wrong way or something.

Would appreciate if you could have a look and confirm.

Barry, i think the alfa tops will hit the fanshroud....as they are come off perpendicular to the webers

Bizarre ·

Ahhh.............. that's the reason

Maybe a flat fan 🤪

Can I add an unproven idea that I'm going to try myself for my Beetle?
If it works, then could you please tell me?
😁

Pretty simple, stacks on your Dells/Webers/Expensive-Italian-fuel-stuffer-upperers, then use flex tubing (seal it up to the stacks with foam and cable ties, done deal) up to an airbox from a Beetle/Commodore/Skyline/whatever, that mounts to the fan shroud just above the alternator, same as the pic above.
Light, quiet, cheap filter. Worth thinking along those lines maybe?
