Hi guys,
one of my fav' threads this one...
I will also install an open airfilter ontop of my Solex carb (see avatar), not for performance, but for good looks, and sweet sound...(I'll lose some weight though..

)
I can understand that making shure that cold air gets to the air intake on the carb make's sense when you are going for max HP, but what is the effect of not providing a cold air supply, shurely not a drop in performance I hope?
Also, does it really make sense to provide cold air to the carb, when you know that the intake manifold holds very hot cooling water, especially to heat up the mixture before it goes into the cylinder? If I recall correctly, this helps keep the fuel atomized while underway...
Also, on many original intake systems, a special shutter in the intake pipe can be set on Winter/summer...where winter make's shure your intake systems take's in pre-heated air coming from the engine...
So for sheer drivebility, I don't think hot/cold air doesn't make much difference, correct?
