Open element/snorkel hybrid air cleaner
Hi,
I dont know if any of you have ever heard of this mod, I have never heard it anywhere before so I'd thought I'd give it a go:
I drive an 88' Camaro 305 TBI, the engine is pretty much stock at the moment.
I cut out a hoop of MDF 7mm thick to sit exactly on top of the air filter (I used the air filter as a template). When the air cleaner lid is reinstalled the lid is held off of the housing walls by a fraction, just enought to be able to see the filter from the outside.
This alows air to enter through the top edge of the air cleaner housing, and also air enters through the stock snorkel. All air still has no choice but to pass through the filter.
There you go, a high flowing air cleaner housing using 50% cold snorkel air and 50% easy flowing air and retains the stock look!
I took my car for a spin right after and the difference is very noticable, plus my engine now emits a deep tone whilst driving

isn't that awsome....
i have some tech info on it for those who are interested.

Here's how the magic was achieved (technical/musical details via F1 Racing
magazine):
As we all know, a V10 engine produces five combustions per revolution at a
frequency per second of 60/(5 x revs per minute), which equals 12/rpm.
Therefore, to work out the revs you need to hit a particular musical note,
you multiply the note's frequency by 12. To play a 440Hz 'A', for example,
you need 5,280rpm. For 'C', use 3,139rpm, for 'F' 4,191rpm, and so on.
Asiatech's French technicians (the engine, despite its name, is derived from
a Peugeot design) simply programmed their engine to run through the various
rev/note ranges in the correct sequence. The result is delightful. And think
of the possibilities - BMW's F1 engine, which howls all the way to
19,050rpm, could rip through the entire Hendrix songbook.

I flipped my lid for a while. I tried it with the stock size filter but the threads on the stud weren't cut down far enough to keep it tight.
So I went and bought a K&N for a TBI truck #1500 IIRC. It helped keep the top of the inverted lid away from the TB so it didn't create turbulance. Now I have a dual snorkel with a chrome lid for a truck.
You're idea is easier than another I've heard. A guy cut off the bottom of a plastic 5 gallon bucket, drilled a hole, and used that. It works I guess.
