Getting PR back... how long does it take?

Hi

After installing vBSEO all Google PR is gone, because all new urls are not recognized by google.

How long does it take before the 301 redirect takes effect and the PR is back on the urls of the forum?

Does it take until the next scheduled PR update of google or does it "only" take as long as google needs to spider the old url and recognizes the 301?

Any experience with that?

Pagerank will be assigned typically once the page is crawled the next time. However, it will not become visible in the Google Toolbar until the next update.
