Pyrometer safe temps

[Jay Darst]

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!
