Mine has reached 1100 on I-77 at Fancy Gap coming north in VA. I think
that is high but I was almost at the top. I have heard that 1200 is too hot.

Brother Dan left Huntley, IL (1 hour west of Chicago) headed for
Maob, UT.

Was on the phone with him as he is traveling thru some hills in
central IA this morning.

Had a question regarding pyrometer temps. As he crests the bigger
hills, the pyromter reaches 1,000 degrees. One hill it reached 1,050
degrees as he made the summit. Interestingly, he was able to
maintain 55 mph in high gear at the crest. The aneroid valve has
been adjusted to provide good fuel volume with only light smoke on
hard pulls.

Is 1,050 for 10-20 seconds too hot?

While off the throttle down the hill, the pyrometer drops to 700
degrees quickly.

On my PT w/6V92, the pyro never reaches 900 degrees. Wonder if I am
not getting enough fuel to make it work hard enough to get the temp
up there?

My FC with out charge air cooler will get up to 1100 on a hard climb, the truck
that has much more fuel delivery and a charge air cooler rarely shows over 900.

Jay,
Have a heart some poor souls have to try and build their self esteem by trashing
others. Remember Chavez at the UN he was trying to outdo the nut from Iran. Made
him feel powerful.

Jay, my 8v92 rarely gets to 750. My manual says that's good.

Nice site Kerry Thanks I am always worried about that. My Truck Garage
said it could melt down above 1200%.

It depends on where the pyrometer is located. It can be before or after the
turbo.
Temperatures of exhaust gases can be about 200 degrees cooler after passing thru
the
turbo. I'd want to keep it below 1200 degrees pre-turbo.
I noticed something interesting this summer when my crossover pipe was failing
and the
turbo not turning as fast resulting in less air to the engine and more black
exhaust. The
pyrometer temperatures went up. With the crossover pipe repaired and a clean
air filter,
the temperatures dropped a couple of hundred degrees.
Prior to the repairs, I would see about 1050/75 at the top of a steep climb like
Raton Pass
on the CO/NM border. I don't think I've seen anything within 150 degrees of
that since
the repair. I dont have oil cooled pistons so I have to keep a closer eye on
the pyro.

Jay, exhaust back pressure may have something to do with it. The
other thing is gauge accuracy and probe/sender location. I think you
gotta get on the fuel prior to a load to spin the turbo finns. the
3208 can crank at 2800 R and the DD are maxed near 2,000. I never
get hotter than 750 on my 8v92. may be fatal to drive a dd like a
cat.

Wont hurt to use a Raytec on a lower idle reading then after a hill
climb with someone reading the gauge inside (will cool as you walk 40
feet back). Dont forget to check the Raytec for accuracy. I take an
oral 98.6 reading, you may find other methods more familiar.

Thanks guys, great information.

Sounds like a self inflicted limit of 1,100 degrees is a safe bet.

Thats about the max that Dan's gage has read.

When we took Dan's FC to RIV, we crossed Mont Eagle in high gear.
Crest the hill at about 50mph, the pyrometer was not working at the
time(the fix was to put the wire back on the gage, by the way...:-|,
daaa), so we had no idea of the temp. That was 2 years ago, had no
related problems since.

Thanks again, everyone, for your information/input, been very
helpful!
