Shewman's High Flow Thermostats

Does anyone have any flow specs?

Bob Shewman is not a member as far as I know, at least I've never seen him ever comment on here about his stats, only G.M. He does have an email address: [email protected] and does answer his phone or return calls, at least he did mine and answered all of my questions. Apparently G.M. had something to do with development of Shewman's thermostats and may chime in here with any test results he did. Knowing now how Shewman's stats are made, the test I'd be interested in is how long it takes to get up to operating temperature with his stats at 0° and how low his stats let the engine temperature go on a long descent down a mountain. That's where I have my real doubts about them.
