Ämne: Re: [DeTomaso] Fw:  Elephant ears

An article in a recent Circle Track magazine by an aerospace engineer
said 
that corrugated flex tubing is very bad at transferring air in any 
quantities, due to the corrugations causing massive turbulence inside,
reducing flow. 
So a 3" or 4" dia corrugated duct (for instance) will transfer far less
air 
than one might think, whether you're talking about engine air or brake 
cooling. And while this is one of those 'jeeeez, of course' things, it
never 
really occurred to me and I tend to pay attention to such details. So
with no 
data and Holley carbs having a 5-1/4" entry flange, maybe a 6" duct?
FWIW,
