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.

up to 215 is safe..... mine runs a consistent 185-190....

Jims5543 03-15-2003 09:51 PM

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 https://www.nopistons.com/forums/pub...DIR#>/wink.png heh



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



i agree autometer is crap.... lol

mine was tapped into the thermostat housing and seemed to read correctly

ThirdGenRX7 03-17-2003 10:47 AM

I didn't know they read more boost than was actually there... where'd you find that out?

vosko 03-17-2003 10:48 AM

you look at gauge then you look at haltech or pfc or whatever EMS you have and see the difference https://www.nopistons.com/forums/pub...DIR#>/wink.png

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.

We hooked up a Mechanical Greddy guage to the car when it was on the dyno. This was a while ago I have since went with a Greddy electrical boost guage with memory and overboost warning.



When we hooked up the greddy at the dyno and went to adjust the profec b we read 11 lbs on the Autometer and 7 on the greddy.



I was seeing 96-97° C. after my runs. I checked my data log and that was max. Plus it cooled right down after the runs. down to 92°



BTW - I got FTD (fastest time of day) for any vehicle there including open wheel cars (lotus 7 and a sprint car) and racing carts. There was a national champ there with his cobra kit car, he was the fastest car in Ft. Meyers 2 weeks ago at the Por-Solo tour. He beat me by 0.01 seconds BUT he hit a cone = 2 second penalty.



It was really cool being the fastest car there. I am going to post an in car vid in the Motorsports section at the end of the week.
