I like 195. The motor needs to run hot enough to burn off acids and other contaminants that will end up in the oil. It also needs to run hot enough to vaporize the fuel that's being fed into it. These guys running 160 thermostats make me crazy.

.

Now i got new radiator hoses and a 195 termostat on it! Tried pressure testing it again yesterday! Pumped it upp to 14-15 psi! I could se directly that i hade a leak comming from both hoses, tried tightening it upp, but couldent get it to fully stop! In about 5 hours i hade a drop to 11 psi! So i left it over night, after 9 more hours (14 total) it hade droped down to 9 psi! I see this cuite big cooling marks under the car! And when i take the dipstick up it still looks like new! What do you guys think?

Two hours later, and its still 9 psi!
