Well gang, I had a fun afternoon of modifying my airbox. To begin with I
removed the thermostat that regulates the airpassage between warm air from
the exhaust manifold shroud and cool air from behind the headlight. I left
the flap open and routed a hose from the air box intake duct to behind the
turn signal. I also opened up the front of the airbox and the right hand
side(against the inner fender). I basically used my Dremel and removed
material between the molded in structural support members. Needless to
say, by seat of the pants testing it is a hint faster. It is *A LOT*
louder! IT sounds very mean..Lots of throaty induction noise! As for
removing that thermostat flap deal, I can't see any downsides to it seeing
that K & N cone conversions in the 20v cars rid of this mechanism
entirely, any comments? What was the purpose if this mechanism?
Next weekend: Advance the cam a tooth and give the distributor a few

Making do with a NA motor....
