Thermostats - Reische vs Evenflo - vs Stock?

[metroplex]

I wanted to drive the car for several days to help bleed it out completely before datalogging. After doing some normal drives (cruising) and some WOT runs, the data is fairly clear. The cylinder head temp is on average 10 degrees cooler than before using the same fan settings (as we are expecting). It seems the faster the engine runs, the cooler the cylinder head temps become. There's also a fairly dramatic change in knock retard. There's at least a 2 degree reduction in knock retard.

Glad it worked out for ya! And that you have seen the results I and others have seen.

With a 2 degree KR decrease, what was your normal KR before? I didn't see that major of a KR change, but I also run E20 and have minimal KR anyways, so KR was not really changed for me (since I had almost none already)
