Under Hood and Trunk
Here you can see the cone filter which
is separated from the rest of the engine compartment by an insulated
wall and receives cold air from the air dam via two vent tubes
and through the hood vent (see below for more details). You can
also see the strut tower brace, the 8 mm plug wires, detailed
intake manifold. I also painted the open grill to match the color
of the car. Most notably, you can see the braces that run from
the strut towers to the front of the car at an angle. Anyone who
has worked in construction knows that triangles keep things from
flexing, so I designed these to help keep the front from twisting.
What you see is steel welding stock that is 3/16 inch thick by
1 inch wide. On the bottom side there is a 1/4 square rod that
is welded on to provide more rigidity.
This is a close up of my new air box.
First the battery had to be moved to the trunk to make room for
this huge K&N. Then I built a wall from the strut tower to
the radiator that follows the contour of the hood and insulated
it. Next I found a 3 inch diameter 90 degree elbow so that the
filter now points toward the front of the car (the elbow required
a lot of porting out on the inside to achieve maximum flow). The
aluminum wall and the insulation reflect a lot of the heat back
into the engine compartment, but I wanted to feed the filter with
cold air too, so I ran two 2.5 inch hoses from under the front
air dam to blow on the filter (they actually move a lot of air
too because my filter gets dirty pretty fast). You can see one
of the hoses between the fender and the filter. You can see other
one connected to the aluminum wall and running just under the
radiator hose. Then I opened up the hood vent on that side just
in front of the strut tower, so there would be a good cross flow
of air. It comes in through the two ducts and leaves through the
vent.
