Toyota's current NASCAR engine does not even have a housing for a thermostat. Big pulley for most tracks, huge pulley for superspeedways, heat the hell out of the oil prior to qualifying but leave the coolant alone, only shut it off if it gets really hot, but about 20 deg. F cooler than the best teams.
Uhh, that's because all of the cooling passages and waterjackets were CFD designed and and 100% purpose built for the specific application for the specific rpm and flow rates the motor is operated with. They also don't need to idle in traffic or warm up quicky on cold mornings etc...
How does that have any relevance whatsoever to making a tractor-engine derived cooling system work on an 80's passenger car motor under conditions it was not designed for?
