Each question bank has 25 questions. The CAT exams guarantee 6 "clean" tests, not 8 - I'm not sure if that was just a typo on your part. After you take the 6 tests, you can continue to take more, but you may start to see some questions repeated.
There are about 1,200 questions in the pool, so there are enough that you will also continue to see new questions - but the percentage of new vs. the percentage of repeats will depend upon how you've been scoring. If your scores are mostly staying in the same range, you'll see more repeats after you take all of the "clean" tests. If your score is changing (hopefully improving!) then you won't see as many repeats (but you will likely still see some).
Remember that just the act of taking practice tests does not improve your score much. Practice tests are checkpoints, designed to show you where you have improved (or not improved) from the work you did since the last practice test. It's really counterproductive to take a practice test more than once a week - you should basically expect the same score, because you don't do much to improve in only a few days. Also, if you're still early in your prep, I wouldn't take a test more than once every 3 weeks. I'd only do once a week for the last few weeks before the official test.
