45 dcoe mesh filters.yes or no?
I'm considering buying some meash filters for my 45 dcoe's
Anyone had any experience of running of these?
Any difference in performance?
Would be good to know before I part with £153
Thanks

Do mean the ones that are metal gauze on the end of a trumpet?
Seem to recall Dave Walker and David Vizard don't think much of these - useless for filtering whilst airflow choking. 
More show than go.

bizarrely i have just spent 30minutes of my life removing mesh from the Dunnell setup I bought a few years ago. So the guy had spent nearly £3K on the
injection setup, and then stuck some mesh (ingeniously tea strainers!) on the end of the trumpets. Appauling......
As above mesh will not filter anywhere near well enough for a road car, and cause chaos to the airflow. Lose lose situation.
Get some proper filters, pipercross type sausage or K+N.......

Agree
Pipercross biggest sausage you can fit or airbox with cold air feed
I do like the look of mesh and trumpets sticking out the side but after following a fuel tanker through the lanes from work my car would be sucking
gravel in for ½ hour
I eat to survive
I drink to forget
I breath to pi55 my ex wife off (and now my ex partner)

Definitely not, they restrict airflow by up to 60% depending on the mesh.
As said, the biggest area sausage, or an airbox which clears the ends of the trumpets by at least 1.5 x trumpet diameter.

I have the mesh filters on my 40 webers and have long since been planning to get rid of them for either a foam sausage filter or k&n classic
looking things.
Either way, the tea strainers are on their way out. They're also pressed right up against the side of the bonnet too, which makes things even
worse.

I have back to back tested the Weber metal gauze filters (AFM4056) on the rolling road a few times now on different cars and different stages of
tune, both on carburetors and throttle bodies.
I can say on every occasion I havnt had to change any jets to compensate for changed fueling and there is absolutely no BHP loss.
I cant comment on other makes as I havnt tested them.

^^ as true as that may be for those specific gauze filters - i's still want something that actually stopped dust getting into the engine
I think this man would agree

Always use a good quality filter, however, if space is limited then the gauze filters are better than nothing.
A good air filter will normally give you a few BHP more, seldom have we seen a car lose power when we test.

Yep there was a fairly recent Walkers Workshop in PPC where these stupid rock strainers caused a huge power loss. Just by looking at them the
reduction in useable area is obvious.
