Pyrometer safe temps

[Mike Hohnstein]

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.

Subject: [WanderlodgeForum] Pyrometer safe temps


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?

All comments welcome (except some of the smart ass ones we've had
more lately)

Thanks
