Got an update for y'all..
So I ordered some filter material off of eBay back in mid-April. Finally got the material yesterday, so I set about making my own filter.
I chose to use the existing baffle inside the can and add some filters to it. This way, it's located in the same spot as the Mishimoto can shown here:
I don't have a baffle plate like the Mishimoto. Instead I'm using a small amount of stainless steel wool (see the original post).
I was unsure of how many layers of filtration to add, so I figured I'd start with 3 screens and see how things go.
This helpful article from Mishimoto states that they used a 50 micron bronze filter, so I made sure I ordered 50 micron stainless steel mesh.
Here's a shot of the 50 micron stainless steel mesh.
And here's a shot of the baffle portion removed from the can. In this photo, I sized the mesh to the opening and cut it to fit, then mixed up a bit of JB Weld to secure it to the baffle.
NOTE: If you're doing what I'm doing, make sure you secure the filter screens with JB Weld or something similar. This helps to ensure that there is no risk of the mesh coming loose and being sucked into the intake manifold.
And a shot of the screens attached inside the baffle.
I haven't reinstalled the baffle yet because JB Weld takes about 15 hours to harden completely. I intend to wait at least 24 hours to ensure that the epoxy has bonded and hardened completely before reinstallation. I'll be sure to keep an eye on the catch can for the next few tanks of gas and keep you guys posted with the results.
