Which twin carbs?

[dasteel]

I'm looking to get a set of twin carbs for my 1600tp but will be upgrading to a 1776 next year. Which carbs are best? Can the carbs be jetted to suit both engine sizes?
Thanks.

Are weber 40 IDF the biggest you can have on a 1600?

You wont need anything bigger than a 40 you'll probably end up with 30 or 32 venturis anyway.
I have 36DRLAs on my 1700 type 1 and they are plenty!

I had twin Weber 40's on a 1600 and it drove lovely. I choked them down with 28mm venturies then played about with the jets till it was sweet.

36's would be the best on a 1600 but both would be the nuts on a 1776.

Anyone got them?
Also will I need an electric fuel pump?

iv just put a set of 34 ICTs on my engine, but haven't got round to putting it back in yet, so can't really offer much help, i know a few guys on here have them though, and seem to like em.

Are your's on a 1600?

empi webbers are a bit hit or miss, one person i know that had there 40s, were absolute *****, the people at race shack couldnt set them up even though they were brand new, but someone else had them with no bother....

 

[gorr2000]

wait a bit longer and get del 40s, they are awesome (especially on a 1776) 8)

 

[antoine]

yeah mine are on a 1600 TP with 1.25:1 rockers.

'Correct' size for carbs is far more about cam and headwork than capacity.
With a stock cam, baby dells or icts should be fine, even on a 1776.
That said, 36 or 40s give you more potential room for the 1776 and, as above, either can be made to work ok even on a 1600 with small enough vents.
Then if you go for decent heads and a cam in the 1776, you'll just need to swap the vents out for something larger
But don't underestimate the cost of a swapping it all around! (about 60quid for vents plus will need new jets too).

Thanks for the replies. Looks like I'll give eurocarb a ring for some advice

I run twin 40 dells on my 1776 and they are fantastic. Set them up and forget about them i havnt touched them for a year now.
They are jetted to the engine size so you would need smaller jets for a 1600 engine...

34's jetted right will be plenty, 40's etc can work and be made work but in reality are too big.

You will not need a electric fuel pump, a standard pump is fine.

Fortunateson has 36mm's forsale. rebuild kits used to be about 20quid or check ebay

I have a pair of 36 IDF webbers that came off a 1500 alfa, i'm told they will work fine as they are on my 1600-1641 twin port.

I'm nowhere near ready to fit them yet so will cross this bridge when i get there

Awsome carbs I have a pair on my 1600 tp give me a shout if you struggle
