You can get a few RSS feeds from ChiefDelphi.
Some are outlined on the '
Extras' page (via the 'Quick Links' drop down up top)
You can also get an RSS feed of the new threads on the portal (theres links at the bottom). That RSS feed matches what forums you have the portal configured to show.
CD-Media will have tons of RSS feeds, as well. Media (both, or just photos or media) per tag, per person, etc.
