Is that with e-fans?? What other mods do you have??

That is with the factory fans.
I have K&N CAI, Borla exhaust, and custom tuned Gryphon.

I cant seem to find a replacement thermostat that goes higher than the factory one, lots of options for cooler ones though. It is starting to get cooler up here in the great white north so maybe a winter front is the answer not a different thermostat. But it would be a pain to have to install and remove it every year. Does anyone know how to modify a thermostat to run hotter. I've read a few ways to make them open at a cooler temp but it seems like no one else is interested in increasing coolant temp. As for the wiring on the Flexalite fan the only problem I encountered was attaching the wire to the a/c control circuit. It was simple in theory but in such an awkward spot it was almost impossible to get my hands in a position to make the connection. If the FF Dynamics fan that bigterp is considering has a feature where it activates when the a/c compressor is engaged the same issue is likely. Other than that the only other issue I had with the install was moving that bake controller but that was pretty easy. Maybe the FF Dynamics will be a different shape and avoid that problem though.

I guess my question is which reading are you going off of? if you use the Cylinder head temp it will be more accurate on the exact temp because it has a sensor, but the other setting, ECT i think is what it shows, is derived from the CHT. so you might be getting what you want without realizing it

Thats an excellent point I never considered. The CHT sit arounc 200-205 usually. Maybe I'll get one of those infared temp guns and see what the actual rad temp is. Longshot had said Jacks truck runs routinely around this temp but I thought he was refering to ECT not CHT though the two are directly related. Infact if I have both set to display at the same time they will show almost the same reading and climb at the same rate up to about
190 F then CHT continues to climb to the low 200s as the thermostat opens.

i.ve got dual shrouded 16" fans (5000cfm total), ford racing rad, and 180* t-stat. fan controller is set to turn on at 200*ECT (~205*CHT). with this combo i can sit in traffic all day with the fans only kicking on every 5 minutes or so (run 15-30sec and cut off). when i'm moving, CHT never goes over 190* with the fans off, 185* if i turn them on via override switch. (only did once to test)

Sounds like that combo works great. It's pretty similar to what I'm considering from FF Dynamics. I'm gonna do this mod most likely in the spring, but it sounds like I have nothing to worry about with dual 16" 6000cfm total rating fans. Do you have your fans set to come on with the AC?? Did you notice performance improvements with the installation of the e-fans??
