You can also make a custom setting in Chrome to send only the parameters to Google that you want. In the Settings panel, click on Manage Search Engines. Make a "new" search engine but make the query go to Google (or YouTube, or whatever) with only the parameters you want. You can start with the url for Google and prune down the input encoding or the sourceid or whatever you want, or just make the path be "/search?q=%s" if you want to go really minimal.
