Temp. Readings - Comments?
 

I took my 85.5 a bit further yesterday...enough to get things really warmed up (car seems very well behaved), and also borrowed a laser temp. gun, and from this got the following results:

Top of Hood (over exhaust location): 144 f.
Valve Cover: 186 to 202 f.
Max Temps. for Headers: 600 to 650 f.
Underside of fuel line over headers: appx. 150 f.
Exhaust just before Cat: 250f.
Cat: 360f. towards front, 260f. towards back
Just after Cat: 160 f.
Rear Muffler: 260 near front, 200 near rear.

I'd welcome comments on the above. Thanks!

Interesting.

Do you remember where the coolant temperature guage was at?

Looking normal or low to me. What was the temp gauge at?

Only one of those temps is mildly relevant. . .the cam box, which seems fine to me.

What I should have said. Interesting reading though. Wonder what the turbine housing on our 31s. would read after a good run. Lol

Lol you don't want to know:D

Four digits, to be sure.

Temp. guage just a little above the first (80 C) hatch mark most of the time...and when sitting at idle for a couple of minutes it goes up to just about the exact middle of the scale - maybe a little above this but so far not to the second (100 C) hatch mark.

Sometimes I think that the thermostat may not be fully seating on its lower gasket - but basically the car seems fine.

On the online forum someone remarked that my header temps. sounded just a bit high, indicating a lean running condition...so I may check into this.

I don't think so and it should be a touch leaner at idle. Imho
