42 DCNFs

[louisb]

Are 42 DCNFs to big for a mild 1776? Would 40 DCNFs work better? (Or still too big?)

stock ported heads
w110 or w120 cam
1 3/8 exhaust

Playing with engine combos for the Manx and trying to come up with a good driver that will keep up with modern traffic. I have the 2332 going in the '66 for going fast.

Thanks,

That was a very common set up for Cal Look cars in the '70s & '80s. I don't see why it wouldn't work today. Those are some great carbs... too bad they're a pain in the neck in the Type 1 engine bay. Other than that, good stuff. Since you're putting those in an open car/body, they'll work well.

42s will work great on a 1776.  I had them on mine and ran an Engle 110 cam with stock valve size heads.  It was so fun to drive and had plenty of torque.  I've seen them run on a 1600 with no issues.  You just have to jet them properly then enjoy!

[louisb]

Okay, then it sounds like the 42s are the way to go.

Excellent choice!

As an added bonus, 42's sound really good

Pain in the neck carburetors which were never designed to run on a VW! They were designed to run on a Ferrari engine, with the throttle shafts across the car. Turning them by 90 degrees to work on a VW engine causes them to flood when turning sharp corners. On a Ferrari they only temporarily flooded when braking hard. You need to make sure they have extended emulsion tubes which Berg sell – or used to – to make them work properly. Used to fit them a lot back in the 1970s and breathed a huge sigh of relied when Weber brought out the IDF and Dell'Orto the DRLA.

Keith may not like them, but I have over 100k trouble free miles on them.  They aren't as purdy as IDAs, but Oh well...

I built a Bus motor for a friend in 1991-92 that ran 42's. Motor was fairly mild, small Scat cam, stock valved dual ports, low CR, 90.5x69. I recall it idled very smoothly, but like KS said, get the bus in a corner, and it was like somebody turned the lights out. He regretted using those carbs, but they came with the bus, so he compromised.
In a dune buggy, IDF's would be a snap to keep happy. You could practically clean the idle jets while driving.
My vote would be for 44IDFs

You don't think 44s would be too big? I would think 36s or 40s for a 1776. Mostly I want something that I don't have to fiddle with after getting them dialed in. Trying to make this something even the wife could drive.

40mm Webers are good for 1700 and under, in my opinion. One of the best and smoothest motor combos I know of for mild street is 1776, Engle 120, ported stock valve or 40 x 35 heads, and 44IDFs
you have Excel?

[louisb]

Yep, I sure do. That sounds like a nice driving motor.

Hmmmmm... didn't know we had a choice here... I thought you had the 42's and wondered if they would work... I should slow down and read all the text

The combo "The Other One" posted is superb! I've run basically that same combo in Baja's, Bugs & Buses... Go for it!

I loved the 42 Specials on my mild 1776 (K65, ported stock valve heads, 8:1)... ran smooth as butter and still returned 25mpg in my heavy Fastback at 80mph. I later put the carbs on an original stock 1600 dual port and they still worked fantastic.

[louisb]

No, this is still a paper motor sort of. I more or less have the short block and a set of stock heads I plan to self port via the Fischer book. I am still debating the P&Cs, carb & cam size. My requirements are that it be cheap, reliable and powerful enough to push a stocked geared 26-27" tall tired buggy to highway speeds for hours on end. (Up and down steep grades too) I am trying to think of a carb that would work with that size motor and my choices were the DCNFs, Kads or even a center mount of some sort. I am following the KISS principle with this one. That way if I break down in Resume Speed, North Dakota with it I can fix it easy.

Thanks,

I remember a very nice white 66 Ghia this mousey little girl owned, a good customer we had @ BH, she wanted a good "freeway motor" for her KG, so we built the motor I listed above with stock valved heads (she wanted heaters) and I swear, that motor was one of the smoothest, yet potent 1776's I can remember. Based on her gender, I was a little nervous of the nature the 120 and 44's, but when I test drove it, it pulled so smooth off idle and just kept pulling, with a wonderful high pitched howl from the carbs as the revs climbed. To top it off, the girl was really pleased with the engine and said it was night and day compared to the stock 34pict dual port 1600.
For a mild daily driver, it's a hard combo to beat. Change to K8 and bigger valves and you've upgraded to very hot street. That's the nice thing about 44IDFs, they run well on a wide array of combinations.

That sounds pretty good.

[Rennsurfer]

Forgive my crusty and old memory... but I remember a few of my friends that liked the 42s and also liked to take turns fast. So they simply added the extra length breather tubes and the problem was solved. Aren't those still available? I think the Berg family offered 'em at one point. But this was almost three decades ago.
