Dick,

Maybe you can tell by the 2nd photo that the housing has two dished out bypasses to let some flow around the thermostat. Seller confirmed to me that no additional holes are needed on provided stat. I was dubious, but those Californians are much more aggressive speedsters than I am. So far, seems to work ok although temp is 10 degrees or so above what I would expect. Another guy has recently posted swell graphs of coolant T with and without thermostat, showing that even when wired open the stat raises the coolant T with stat mounted in hose, as I understand it. Don't know if there would be a problem under conditions more demanding than a Michigan summer, and don't know if one or two 1/8" hole in flange--like a I always used in the past--would help.

It really is sort of goofy looking, so I would only recommend it for engineer-types who find beauty in function.
