If you are using a 301 from an old page to a new page within an existing site, it gets picked up fairly quickly. It is all relative to the indexing behavior on your site. If you are indexed daily, you'll probably see the new page in place within 48-96 hours, maybe a little longer.

If you are using a 301 from an old site to a new site, that is where the problems appear to be happening. I do not think PageRank has any relevance in this instance, at least based on my experiences. There are also many topics here and at other fora where the above has been confirmed.
