air filter layout on my weber

[BigNazty114]

Ok, so I'm not too sure on how I would want my air filters on my DCOE Weber. I have thought of three things.
(the box in the pictures is the weber, and the circle things are my two K&N filters)
1. 45 degree bent tubing from weber to filters

2. 90 degree bent tubing

3. no bend


Which one would be best?

EDIT: I won't be back on til late tomorrow, I hope to find some answers

you want the coldest possible air with the fewest bends to keep resistance down.

You want the velocity stacks to be the same length. so the runners to the intake side will be the same length.

Ah, thanks, I'm new at carb stuff. I'm thinking about just putting two short pipes so that I can actually put the filters on something. Thanks Flashmn, didnt know that

[Flashmn]

Just use filter socks like I have. One on each velocity stack.

[BigNazty114]

whoa, I just looked up those filter socks. First time I've seen them...but the thing is I already got two K&Ns from 2wickedtoyz when he sold me his weber.

[Flashmn]

sell the K&N's to someone and use the filter socks with velocity stacks.

The best way the webers work is without anything on them

^ too much dust and dirt in ol' country Oklahoma to be running without a filter though

VERY VERY VERY WRONG!!!!! NEVER run without a filter, not even race cars run without them. Sure hey show the cars off without them, but most BTCC etc cars have those socks on them.

Your engine wont last very long without them.

i am making my setup like this. i have extended air horns going from the webers into a box that is fed by air from the outside. the air horns have socks on them. plain simple and very effective.

The motorcycle foam socks are definately the best, I don't like airboxes much, unless they're real big.
If you can, try and find a set of the Maserati air horns from the 42DCOE carbs, they're rare, but will add around ten hp as they flare out more than the std 40DCOE ones. May want to look in the Weber parts guide first to see if they'll even fit against the firewall.

Also, since we're talkin' Webers, don't be afraid to open up the venturis to 38mm, on the 40s, works great!
Here in the states, there's a certain commercial electrical conduit connector from the hardware store that will work perfectly when turned down on the outside as a 38mm venturi. Cheapest Weber parts you'll find.

Riiiiight

Oh yeah, my results were in fact on a much more capable engine than a 4af.
When anyone mentions webers, I tend to think about my experiences, and forget that we're only talking about 4af engines here!

[Flashmn]

webers alone wouldnt put out 10hp gains with set of airhorns.
