Hi,
=20
that is a close to death temperature where the oil starts to suffer and =
ages.
It indicates friction inside the engine somewhere. Many times it is rod =
or crank bearings that cause high oil temperature, when things start to =
go wrong.
=20
Infrared temperature sensors:
There are things to know about them to measure correctly:
1. They work like a photo camera, they have an objective aperture =
=E2=80=93 in most cases a wide angle objective 1/20 or 1/12 =3D means =
1=E2=80=9D away measures a surface of 20=E2=80=9D or 12=E2=80=9D!!!
2. The laser point is NOT the spot you=E2=80=99re measure, it is only =
the direction you measure
3. If you want to spot measure something, get as close as possible to =
that spot as you can=E2=80=A6.if the surface is not too hot, touch it =
with the sensor
4. Metallic surfaces give wrong readings, cause by the Maxwell theorem. =
Means, your readings will be too low. To compensate this problem, paint =
the metallic surface or of that is not possible, put a peace of tape =
(any color) and spot measure on this tape snippet.

Betreff: [Fot] Oil temp
=20
Amici,
=20
I'm sorting out a new to me race car and don't like that the oil =
temperature gauge reads around 290 degrees. I've never had an oil temp =
gauge on previous cars so I'm not sure what's normal (240?) but 290 =
seems high to me. Yes?
=20
More temp info: Air temp is near 100 degrees. Water temp is steady 185 =
degrees. Big aluminum radiator with electric fan. No oil cooler. Oil =
temp sensor is in the aluminum finned oil pan. IR temp gun says the =
outside of the pan is 170 degrees. Maybe the oil temp gauge is wrong? =
I wouldn't expect such a big difference between the outside of the pan =
and the oil temp.
=20
Engine info: mild engine, stock compression, fast road cam (270 is my =
guess), supercharger with the medium size pully, pump gas
=20
Maybe I'm worrying about nothing. I just know that racing in 2 weeks at =
Eagles Canyon in Texas is going to be hot and I want to make it through =
the weekend.
=20
Thanks,
=20
