I'm using the stock 195 thermostat, and on average my coolant temps are between 196-203. I pulled up a log from last summer, and after a 2nd-3rd gear pull revving as high as 7,829 my coolant tepms were 193 during, and shortly after increased to 196, 200, then back down to 196.

I never have problems with moving, it's only if I'm in traffic on hot days that my tepms get to about 203, but never really hotter even if I'm stopped on the 401 for 20 minutes idling.

My stock fan is running like it would on a stock car, in other words I don't have it wired to be on all the time or on a switch.
