Don't swiss cheese your Airbox




Casey,
I'll have to disagree with you on this one.:)
It will sound real cool and turn heads, and when the engine is cold you
might find a few ponies. Once the engine is warm you will actually loose hp,
but it will still sound cool. I know this from experience swiss cheesing my
own airbox. There was also a dyno test in EC about a year ago where a Jetta
II was Dyno'd three times, once with the stock setup, once with a standard
P-flo, and once with the P-flow in a box seperated from the engine and fed
air from the front of the car. The boxed P-flo did the best, next was the
stock setup, and lowest hp output was from the exposed P-flo.
This is the reasoning. The colder the air, the more oxygen, and the more HP.
The best way I have found is to keep the airbox sealed except the inlet
hole, put a flexible hose on the box and run to the front of the car
somewhere. For a while I pulled out my high beam light, attached the
flexible tubing to the airbox, attached a HVAC reducer from a plumbing store
to the end of the flexible tubing, attached the reducer to the back of the
headlight bucket, and used a wire mesh grille inserted into the headlight
retainer ring to keep out debri.
This method is not as loud but it actually works. If you live in a rainy
area be sure to put drain holes at the lowest point of the flexible tubing
so that you don't end up with water injection and switch to a K&N or other
oil coated foam filter.
I have heard of some people opening up the airbox on the inner fender side
and drilling holes in the inner fender to get air from there, and have also
heard of drilling holes in the bottom to get air coming up from between the
bumper strut housing and the inner fender. Just try to keep the box sucking
the coldest air you can.
Hope this helps.
