So much theory and myth.
First and foremost these are aged semi (mostly?) clapped $1500 cars *nothing* is gong to be their fountain of youth,
so this is all just Pub Talk :-).
I have been running SCCA 'weekend racers' sporadically since '69 and currently (still:-) an ancient Yama TZ350,
on MY equipment, thermostat temp does in fact, have large and immediate real world effect on running temps, nothing subtle about it.
Temp control is how one sets up for Max Power, just another tool. My Yama is currently running 50c :-), with some thoughts on trying 45c. Down a bit from it's oem 80c as a factory racer, albeit decades ago. Years go by and theories change.
Couple of weekends racing, discards a lot of hearsay, quickly, helluva lot of fun too. Try it :-)
