ever do any more work on your modifying a thermostat to run hotter idea?
i thought it sounded easier to do, and/or reverse if need be.
i had shelved the idea myself because my car seemed to idle rough when it was up over 200deg, then recently the rough idle progressed and i figured out i had an intake leak. after repairing it idles fine at high temp. so i'm thinking it caused a noticeable difference in idle quality if i was at 200deg vs 185deg, because the engine uses enough less air at 200deg. that the leak would cause that cylinder to lean out enough to miss.
long story longer - i'm thinking about this idea again myself and it seems like it should be a sure thing, mpg improvement wise.
