Oil filter flow comparisons-where did they go?

[Weezz]

There used to be a section here where they tested different types of oil filters and the results showed the difference between pressure in vs. pressure out. Has this been removed?
There was also a section here somewhere that had pictures of oil filter that had been cut open to show the internal construction. Has that been removed also?
If not, can someone provide a link to these?
Thanks,

Ok, I finally found the flow tests, the internal filter pics seem to have been deleted from the server.
If anyone has a workable like I'd appreciate it.

The filter pressure drop tests sound like the work "Grease is the word" did on his website and posted links on BITOG. That study is presently offline. It's potential resurection is discussed a bit here... Filter flow tests

The pictures of oil filters cut open was also probably links to other sites. You can use Google to find sites with cut open filter pictures.

Edit: Where did you find the flow tests?
