<VV> Re: AIR CLEANER HOUSING

[Bill Elliott]

I agree that the snorkel is designed so that the length and taper are 
tuned for max efficiency but within the confines of the PRIMARY purpose 
being intake noise reduction.... that's like saying that Cadillac 
Eldorado springs are tuned for max performance... within the confines of 
the primary purpose being a smooth ride. While they may be tuned as well 
as possible given the primary design characteristics, improvements can 
usually be made.

Now depending on the application, you CAN really disrupt the designed 
airflow (the airflow is sometimes better with a restrictive intake 
system than the bare carb sitting there alone) but that doesn't mean it 
can't be improved on when you are not concerned about intake noise.

Flipping the top on a Corvair air cleaner system can only help it's 
performance (IMO) due to the remote location of the filter... and I 
agree with the others that the airflow at the turndown to the carb can 
be dramatically improved. The individual K&N copies from Larry's Corvair 
not only look and sound great, I suspect they do a decent job of 
managing airflow turbulence.
