is there any effect when you put a long pipe on the top of your carb? kinda like a cold air intake for a fuel injected engine.

i don't want to hear the carb anymore so i was thinking about making an adapter for the top of my weber to a cold air kit i have that looks like it's about the same size and profile as my weber's barrels.

the secondary's nice to listen to at first but i'm sick of it now....

a buddy of mine was telling me that if you can smooth the air flow out a little and kinda make it swirl a little that your vehicle will run better. any truth to this?

I think you would get a bit of a gain even from just slapping together some corragated sewer pipe on. There are a lot of opinions around about airflow, swirling or smoothing, etc. Any gains you get from this are going to be small. I say just make it work and try to keep the inside of the contraption you come up with clean and fairly smooth.

You can get adapters for the top of the weber to various diameter round holes. That and an elbow of some kind would get you into the cold air intake kit you already have. I think http://www.carbs.net carries a bunch under weber air filter adapters.

I was figuring to do something like this on mine someday soon for much the same reason. I actually took the weber off my old truck because I got tired of listening to it breathe. The only thing that sucks about a weber is the sucking sound of more air screaming down its throat. Fuel Injected Troopers run a tube over to the drivers side fender just behind the headlight to where the filter is. There is an airbox around it, and air feeds in from another tube across the front behind the grill. I figured I'd do something similar minus the grill pickup. It would be nice to have things sealed with an option to add a snorkle later one. 78 and later LUVs already have that air feed over by the head light, so that would help you get colder air in even without some sort of airbox to keep out engine bay air.

You may risk carb icing in the winter with a setup like this. You need some warm air in the winter to prevent this from happening. With high humidity and near freezing temps, your truck will lose power slowly the cut off. After a few minutes you will be able to restart the truck and drive awhile and it will do it again. What is happening is ice is building up in the venturi of the carb till it restricts the airflow enough to stop the engine.

i had thought about this ....

i plan on setting it up for a cold air intake with a warm air valve and the breather hooked up .....

i've been having problems with how the truck runs as it's warming up and i don't like sitting in the cold keeping it running in the morning......

To some extent icing problems will depend on where you live. Around here we only rarely see temps down to 20F, so most of the time it isn't a problem. I know a carb can ice up at higher temps than that, but when 20F is your worst day, the rest are quite a bit higher.

I've tossed a number of ideas around for getting better warmup air. You could tear into a stock air cleaner and take out the flapper valve for the manifold hot air intake, or perhaps just rig up something similar with parts from another vehicle. Then run a tube over from the manifold heat stove to your valve. I was thinking something like that with a manual control, but the vac powered flapper valve would be cool to have in there to make things work right on their own. Then again, part of going to a weber is to eliminate a bunch of potential vac leaks all over the place.

Whatever the solution, I am really getting tired of listening to the stock weber filter setup. Even going to a stock air filter with an adapter would make me happy I think.

how about 2 diff. types of cold air intakes, this is on a 1.8l i'm figuring so, just route one of the cold air's to one side (intake side) then make another one that goes to the other side of the engine (exhaust side) and put it close to the exhaust manifold, thus heating the air inside, or punch some holes in it too to get warmer air + the cooler air from outside but it's depending if you have the time, $, expertise and your using a cone filter on the end
