Pyrometer for C15 single turbo MBN; How hot is too hot?

haha thats cool. BOOM! You know I had an older man swear to me that "back in the day" they used to run some cummins that when conditions were right at night they could see fire commin out of the red hot pipes... yall think he was smokin something or could that happen.

 

I don't know when "back in the day" was, but I have been driving since 1973 and i've heard that. but I never saw it

 

man would that be cool or what. oh yeah I remember he said it was a non-turbo cummins that the fuel was jacked way up on. probably early 70s

 

Ive seen it happen in a 362 cabover Pete pulling a 8 axle MI train with a 425B CAT when the guy blew a turbo and kept pushing it, fire was coming out the stacks.

 

I have seen it several times. These were non-turbo cummins engines that you had to crank up the fuel to get to run.

I had a cab over KW pass me one night and the whole under cab was glowing. The exhaust manifold was so red you could almost see through it, and there was fire about a foot long out the stack.

He would let off and it would get dark under the cab, them back in it, and it turned red again.

He had to run beside me a while, as the truck in front of him was a little slower, so I got to watch a good show for a few minutes.

Things like that is where the line from the song "six days on the road", that goes "I got a flame from my stack, and thats smokes a blowin black as coal" came from.

 

I remember that very well. My first had a NH 250 and RT910 with 4.44. It's my avatar. The 335 was the daddy rabbit for a while, if you could keep head bolts from breaking. When Cummins added the aftercooler and made it a 350 things really improved.

 

I had the fuel turned to my old 250 and it broke head bolts a few times also. It had a weed burner exhaust, and that smoke would roll out from under the trailer.

I you were lucky, you could take off a valve cover, take an arc welder with a heavy rod on it, stick it down the hole the broken bolt was in, and quick arc it, and stick the rod to the bolt, then release the rod.

If the bold wasn't too tight it would back out by turning the rod. If not, then the head had to come off. I got pretty quick at swapping heads.
