More important than water temp, what is the oil temp? If you can run the water tempat 120-130 but the oil is at 210, your golden. A lot of guys run a oil thermostat/ bypass system for this reason.

1/8 or 3/16. All you are doing is getting rid of steam pockets and smoothing out the temperature fluctuations. Arizona Speed and Marine has 120 deg. themostats. That's what I use. Damn I posted as Donna again, Ian

Nocigarette by drilling holes in your thermostat outer rim you will run colder.I hope i'm undestanding you correctly.I always run a crossover system and can dial in the temp as i want.You have a bypass already.For you to get warmer you need to go to a warmer thermostat.Still drill an 1/8" hole in the rim.Where i live i seem to be to hot.I drill sometimes 3, 3/16" holes in the rim and reduce flow through the bypass.I would suggest a 160 thermostat and start with one rim hole and go from there.
