I have a 93 that already has a k&n aircleaner witha a stock airbox I just installed a high tech turbo stage three commpresser upgrade and its not getting enough air plus my boost is low i have a clean filter guage and i run a mile down the road and its half way up everytime any help would be great

 

Some time ago one of our members made an air box out of a cook pot that looked and worked well using a big honk'n air filter. He had some good photos of the fab and install. Try a search under BHAF. I am thinking of doing something like it myself.

 

I think it was BC847 who made the stock pot airbox.

 

BC847, that guy ain't right

And that comment is from the guy who said "and it's dishwasher safe" And I still like it. Even if it is forever named "The Stock Pot Air Box."

 

I'm almost done making my stock pot cold air box, it has been a slow and tedious process but I am pleased at what I have done so far. It appears to be able to easily outflow the stock piece.

 

Post some pics first chance you get.

 

I'm headed out the door to work on a few fabrication projects, I'll see if I can get pics together tonight. I did change the design slightly for strength.

 

Till I find a good one for me to buy for a replacement (seems like all the goodies for these trucks start in 1994) you could do what I did. Just take a cordless drill and use about a 3/4 inch drill bit and start drilling in the stock air box....Swiss cheese it, if you will. It ain't pretty but it's pretty effective and it WILL breath better. The only drawback is that the air filter will need cleaning/replacing more often. But it works!! Chuck
