This is a little something I cooked up for a design project in school. I haven't actually got a prototype done yet, but time permitting, I plan to try this summer...
The idea is to make a, for lack of a better
term, "Ram Air" for the car. I know, this has been done before, but to
a K-car? Yeah right, no one's that dumb...'cept me. The intake track starts
in the front bumper. A hole is cut out in the middle, and some relatively
fine screen is placed over it and a box made to fit behind it with a 3"
diameter hole facing the drivers side. From the hole is run 3" tubing,
probably all exhaust tubing but I'm looking into some big rig intercooler
hose now that might work better. One option here is to place a cone filter
in the scoop and eliminate the filter in the airbox. The hose ends at the
stock air inlet behind the drivers headlight (Quick note here: if you want,
you can avoid all this work by removing the headlight altogether, but then
the police tend to get mad...)
The air is routed through the computer
as it would normally go, then to a 3" smooth hose to the airbox. The Airbox
can be either the stock one or I have designed a custom one to further
increase flow. The air filter will have to be a better one in either case
(K&N makes one for the TBI 2.5's, should fit...). The downside of my
custom job is that it eliminates the exhaust heat, so anyone in a cold
climate (like me) will have to go back to the stock airbox in winter or
face the consequences. Below I have scanned my original blueprints, but
keep in mind all measurements are in metric (I'm working on converting
them back to SAE now for you Americans...).

Have fun and let me know if you try it! I'm constantly refining the idea and would appreciate any input.
