Perhaps the best way to search the talkmorgan website is not to use the internal forum search function but to simply do a google search, eg in google enter
normal rpm for a duratec site:talkmorgan.com
The site: option means google will only return results from that particular website (ie Talkmorgan)
You can force Google to find web pages that contain a particular set of words like this:
idle AND rpm AND duratec site:talkmorgan.com
