<VV> Re: AIR CLEANER HOUSING

[Michael Kovacs]

The GM engineers did not waste time designing the snorkel(s) just to make it look good. That cost $$. The snorkel(s) are just a venturi accelerating the air through and the dropping it for volume inside the flow pipes. The  whole system is also a silencer and fire suppressor

understand it after a rochester carb engineer caught me with it flipped is the 
venturi length and taper was tuned for maxi efficeincy. he said if i showed up at 
the plant he could demonstrate that fact. so i never flipped my lid again , 
just retuned that draned egr and flow of converter. this was on 70's vintage 
oldsmobile 403's etc. corvairs are the same priciple.messing with the air 
cleaners is like tunning a stack on fuel infection units i guess. you real 
engineers can set us straight on all of this? intake and exhaust tuning is a real 
science if you want to nit pick. me? i just drive them.earlier that 64 they only 
tried to keep the noise down , not tune them.
