After pondering it for months I'm going for a twin carb set up, what's the best option? I'm thinking weber idf 40's csp linkage csp manifolds. Anyone running the same ? Pro's and con's Things to avoid? All help appreciated!! Thanks!! Sent from my SM-G950F using Tapatalk
Do it. If you've got a type 1, you can then sling that horrible T-shaped manifold over the fence. Your van will thank you for it. Weber ICTs are fine, or the IDFs, or the Mighty Dellortos. The CSP linkage is a good 'un. Budget for all the extra kit on top of the carbs -- it soon mounts up.
Yeh type 1, I'm a bit reluctant to buy a second hand set up you don't know what your getting, there are a few different kits available online start adding the k&n's and csp parts and it starts to get exspensive Sent from my SM-G950F using Tapatalk
You might get lucky second-hand (I did), but buy "new" if you want. Don't forget you'll likely have to re-jet the carbs, which mounts up (any twin-barrel carb you'll have to buy four of everything). I'd skip K&N filters - the generic ones are fine, I found. Buy a bottle of K&N oil to squirt them with. I've got Dell DRLA40s.
Here are mine. First thing you notice is that you've got an engine that can actually breathe properly.
One sad thing about new ICT's is the crap quality. My throttle bushes were worn after just 6 months use. Not leaking enough air to be problematic yet, but quite disappointing when I have an old set of Dells which are as perfect as the day they left the factory.
Looks so much neater!! Would you bother with 34ict or go for the 40s? The latter Are half the price, however I want to do it properly and be happy with it Sent from my SM-G950F using Tapatalk
Everything ends up much neater and accessible. Plenty of folk use ICTs. They're nice and simple - really much the same as the original Solex. They're single-barrel, but do you really need one carb per cylinder? It'll bring your Type 1 to life, whatever.
I’ve got twin dell 40s on our 2l type 4 with csp bell crank linkages. Was a good choice in my opinion.
Genuine Webers from Coolair, but new stock. The old original ones were probably made of a better alloy than the crap they come out with today.
I hire 4 buses out and all have Type 4 2.0 engine except my original personal van which has a 1776 engine. I was begrudged to change the carbs as I thought they would be wasted on a hire bus and 2 the ICT's have been pretty good in that they return 30mpg on the motorway. Performance feels more exciting than the 2.0 Type 4. The only reason I brought the Dells was because I hate the ICT manifolds in that the vacuum take off castings make changing spark plugs very painful.
IDF40s are too big for a 1600. To determine carb size – square root of (cylinder cc X maximum rpm) divided by 40. Maximum rpm for a bus will probably be circa 4,500. Square root of (400 X 4,500) = 1,342 divided by 40 = 33.5. 34ICTs are near perfect.
If you have a 1600 then consider Webber 36’s or Dell 36’s ... 40’s are a bit overkill and you will have to run a 28 vent anyway ... I’d go a decent secondhand pair of Dell 36s
I find 40s with 28mm vents work just fine They are physically big, tho', although that's not a problem.
It just trying to find a decent set, and not having to trade a kidney for them Sent from my SM-G950F using Tapatalk
