What knd of engine temps do you see.



I have seen as high as 207 degrees when I am Autocrossing. Normal everyday driving I see 195 to 200 during a 90 degree day.



Is 207 too high??



Is there anywhere I can get a 180 degree thermostat? Stock is 190.



Thanks for your input.

Thanks Vosko. You can imagine my look of panic when my P.O.S. Autometer guage was reading 215 today.



I quickly hooked up my laptop and read 97° celcius. I double checked my conversion this evening and came up with 207°. These FD engines run pretty hot huh??



BTW - the Autometer temp guage is reading 10° hotter than the real temp.



Lets recap Autometer Temp. Guage off 10°



Autometer Booste guage reads 4 lbs. too high.





Autometer = Crap!

Bump this **********er....





Um... My stupid autometer gauge won't go over 140F. I KNOW that's not right... I have the coolant line to the TB tapped for reading...





What the hell could be going on?

my autometer water temp gauge DIED. i went all DEFI gauges... expensive but worth it.



contrary to popular believe i think the AUTOMETER gauges were made for FD's.... they read to hot and too much boost. this must be a design on purpose so that they dont' actually damage anything heh



jim if your TII is running too hot get higher flowing fans or pull the thermostat.



i agree autometer is crap.... lol

you look at gauge then you look at haltech or pfc or whatever EMS you have and see the difference

what are the normal operating tempatures for a hot summer day and a cold winter day... with the car fully warmed up? is there a huge difference? i need to find a safe cut-off point as this will be my first 7 summer.



cold days my engine temp is about 92 - 96 C fully warmed up.



thanks.
