AIR resurculates your exhaust from the exhaust manifold into your intake kinda like a mini turbo

 

and ftl...emission laws...fudgin tree huggin tofu fartin hippies [:@]

 

mini turbo? no exhaust gasses enter your intake in a turbo, the exhuast flow is the means by which the turbo is spooled...

 

incorrect http://carcare.org/Emission_Control/air_pump.shtml

 

and what you are describing is the exhaust gas recycler (EGR). the EGR has a pipe coming off the manifold (pass side in the ls1), has a valve, and a pipe going into the intake manifold. the air however is not attached to the intake anywhere, it has a fan that sits under the drivers side fenderwell, and little tubes that go to each exhaust manifold. I believe all it does is adds a little fresh air to the exhaust.... not sure why, maybe it a little unused oxygen helps the catalytic cycle or something....

 

oh my bad, got it mixed up

 

i actually saw that website earlier specter and thats the one i didnt understand haha
but when u summarized it it made more sense.
