50mm readily available side drafts ?

[Jack]

Going to need a massive amount air going into a 16v head
Looking for any recommendations for 50mm side draft carbs that you can get “cheap”


I know harleys have some big carbs but that’s as fas as my knowledge goes

Will make a custom intake etc

Thanks

SU HS8 are 2" and used with some pretty big Healey and Jaguar engines. If I recall correctly Mike Jr or Mike Sr in their project 122 thread had aftermarket Weber clones. They may be available in 50mm.

The chinese Weber clones are available in 50mm.

I thought of those but looking for more modern stuff

Keep the suggestions coming

Found some common mikumis but they’re are 46s I think which still isn’t big enough.

Yeah but Webers get choked up so it’s not really a 50

[Broke4speed]

What kind of 16v engine would need more air than a set of quad 50mm DCOEs could provide, even choked down to 46mm? Not trying to be a jerk, genuinely curious .

I’ll post specs when it’s all done

Doing port work (especially on intake- sloppy casting and room for better flow) and larger valves on intake and exhaust


There’s got to be something more modern Webers

If you're going through all this trouble with a mega-ported head, why not just run EFI? I'm almost certain you could find some 50+mm ITB throttle bodies that won't be as much a restriction as all the internals of a carb.

Because I really don’t want to efi an amazon

50mm TBs are something I’m thinking of for another car
(I have a few 16v and even more Volvos)

Looking at 55 Webers ... ugh

Vergaser 46s are huge money and still a bit too small

Go big or go home.

If that's not in the budget you can get FAJS 55 DCOE's cheap.

if I start saving now I should be able to buy them in 200 years


whats the deal with solex sidedrafts

volvo used them on their race 16v but they seem to go for cheap?

[hiperfauto]

Yes they did. These have a tag that says "VOLVO 16 VALVES " on them but they're only 48's.



Where do find you them cheap? It could be because calibrated parts are hard to find.

[Jack]

there's few on ebay


call me and lets talk about those ;)

Here in Finland we use those Chinese Fajs carburators in "Folkraces"!
And there are good at least in WOT conditions!

They're similar in function to the Weber DCO/Es, but use many completely different components that don't interchange. I tried to save a few bucks buying a set of DDH 40s, and found out the hard way that replacement parts for the Solexes are hard to come by.

Also I think Solex used zinc bodies, instead of aluminum?

If the reason you dont want to go efi is looks, convert a carb to efi? there is some good kits out there for like Su;s and the big ones are usually cheep.

EFI is probably going to be cheaper and easier to find than 55-sized DCOE carbs.

You could try a high CFM 4-barrel, but I'm not sure airflow would be your friend with a setup like that.

[Jussi Alanko]

Here is 55mm Fajs, they are good carbs for their price.

Not for looks, just something I want to do with a 16v

The Chinese Webers seem nice but aren’t that much cheaper than 50/55 Webers

Once the headwork is done I’ll flow the head and find out exactly what I need

Independent throttle efi 16v is going on a different car
