[Land-speed] On Topic, lol... Air Box for Filter Questions

[Larry Mayfield]

The Sunbeam has a very tight engine compartment especially when the 
turbo plumbing is in place.  I always use an air filter on either the 
turbo inlet or on the mass air flow meter for the normally aspirated 
version.  I am currently toying with th enoion of putting the filter 
into a box hat can get its air from just over the top of the hood, up 
front, where a tiny bit of dynamic pressure can be recovered.  My main 
question is: is there some rule of thumb for how big a boix must be or 
how close it needs to be when enclosing the filter?   If the filer is 
say 6 inches in diameter then what diameter should the enclosure be on 
the inside?

Any thoughts on this from anybody?

Yes, I could just grab the air directly, but, I like the notion of the 
air filter keeping salt particles out of the engine.
