I made a cold air/ram air sort of setup on my 305 TBI. I drove a while and remived the air filter to see if the intake lets in more dirt. I found that my cold air intake lets gravel into the housing. It did not get past the filter, but I need to solve this problem now. Any suggestions besides scraping the whole thing? I was thinking screens.

 

sounds like you solved your own problem.

 

Yeah, just put in some screens. You should be able to find something at home depot like screen door material and use that...

A screen from a home depot or somthing like that would be perfect!! I had the same problem with my home made ram air then i just bought some screen(like the one they use in doors) and it kept all that stuff out.

I was goign to do that with my car, and for the pre-filter to use an old thin sock or panty hose. A screen would be nice but bugs would clog it. A sock you could remove and wash or put a new one on it in a matter of minutes. They both have their advantages.

Btw what did you construct your cold air intake out of? I was considering aluminum downspout drain gutter stuff. Its like 2" x 3.5" square and would fit nicely. I'm just worried i'd get it too close to the belts!

I used an aleuminum dryer vent hose. I also didn't run it up past the belts. I removed one of the horns and ran it up through the driver's side fender. I'm not sure if it has too many bends in it or what. I would think it slows the air down more. Well, it's better than the stock, but I will probly just use some screen. I'm not too picky about bugs. As soon as I can figure something out, I might run the hose between the belt and fan, but for now, it wors good. I hope that gave you te info you needed.

 

That was my first idea, but it seemed a bit clunky.
