Hypertech 160 STAT
Hi I just got my 160 stat installed my Jon, a fellow board member. Now I have a question. I thought the reason everyone uses these thermostat's is because they operate at a lower temperature. I let the car idle and warm up, basically to see what happens and when it when past 210 mark I was surprised. So i shut the engine off and opened up the two bledder screw jon showed me and told me to close them when they start spitting coolant and I did that. Then started the engine again and same thing went up to 220 and the fans came on and temp cooled down to 210. Is it suppose to do that? or did it get a dud?? Thank you in advance for all the help.

teh stat allows you to operate at a lower temp. to take advantage or it you will need to change your fan temps on/off in the computer. once you have teh fans set you can start to tune to take advantage of the bit more power you can make at the lower temp
later

If you're sitting still it will still go up to 210 or so... get moving and it will go down... while moving my temps usually around 165-170

If the engine is too cool it will wear more and the parts won't be sealing as well as they would at the designed operating temp. Lots of tolerances get messed up when you run too cool. I like 180-195, anything cooler has never been proven to make a car faster. Yes having a cooler engine will make more horsepower so LONG AS the intake hasn't already heat soaked. Once that happens you're almost better off with a 180 stat since the rings, bearings, head gasket and what not will all be "tighter." Piston rings wear when the piston is loose in the hole, cold block = extra wear.
It's all up to you and I'm just giving you my opinion for whatever it's worth.
Also, definatly change those fan temps to match the stat. You could damage the 160 stat by overheating it up to normal temps on a regular basis. They're wax, wax expands, overheat it too much and the wax leaks out the seals .
