For your head temp to be 144 deg while running, sounds like your thermostat is not closing all the way rather than opening sooner:-?Take the thermostat and seperate it.. In the center of the stat, there is a hole....place a BB into the hole, put stat back together!! It allows the stat to open sooner!! It's supposed to be equal to a 160!!

I'll be swapping out my tstat shortly, too. Think I'll go with the 160 since I don't have to worry much about heater usage in Central Florida.
Will add another vote of confidence in the Vinci Constant Fan Monitor controller. Have one in my 96 GS coupe and it works great. Adjustable via a tiny rheostat to set the fan ON temp. I set it to full when at the track so the fans would be on all the time while waiting in the staging lanes. The unit works in conjunction with, not in place of, the PCM so if it goes bad for any reason the PCM takes over.
Concur on what others have said about needing an oil temp of 180 or more for proper lubrication, but keep in mind OIL temps are generally 20 degrees or so HIGHER than water temps.
The stat is available from a number of sources, Eckler's for one, I believe.ZO6/Les said:Would you mind telling me where you got the fan controller and 160 thernostat? I plan to go that same route.
