i have not tried this yet do to lack of money but what if you route the a/c line from the a/c compessor to your intake, grant it you wont have a/c but wouldnt that give you a nice cold boost of air. I dont mean this as the only source for air to come into your intake but as an insert to cool down the air. OR what if you took a 5 inch pipe for an intake and welded a peice 3 inch tubing inside to form a sort of sealed container 2i nches in diameter on the outside of the three inch tubing and the drilled two holes in the sealed part and filled it with liquid nitrogen or liquid helium(very hard to get a hold of) so tha the 3 inch pipe is frozen to a chriogenic state and the air that comes through it is severly chilled and condensed, although it wuold have to be circulated using insulate lines and a special kind of pump to pump it or maybe work it on the fact that a fluid flows from high pressure to low pressure to somehow make it pump on its own pressure. whatever tell me what you think!
