So funny story....

Ok not really but I finally got my pyro in today. Turns out I've been running about....... drum roll please....... 1300*! Ouch

Nice....not really.

When does it hit 1300*? Any heavy black smoke at all?....Wait, just looked at your sig so Im guessing it does

 

[Hyde]

Actually it doesnt, as hard as it was I refrained from turning up the pump till I got a pyro. Looks like I wont be for now. I hit 1300 once on the big grade heading out of town with the go pedal down

Big grade heading out of town??? you aren't by any chance in Lewiston, because if you're heading up that grade, any engine is borderline meltdown climbing that sucker

 

[Hyde]

No I'm north of there, that is a mean hill though. Well I couldnt resist turning up the pump. Actually it is cooler pulling the hill now since I dont have to have the hammer down all the way up

Keep in mind that unless you've tested it, no pyrometer can be guaranteed to be 100% accurate. This is why guys who push it to 1250 or 1300 might get lucky. Your probe/gauge combo might be reading 100 degrees too hot, especially if you shortened the wiring at all. Better that way, then 100 degrees too cool though.

Yea I know it isnt 100%, its an Autometer cobalt directly in the manifold however so it should be pretty close. No alteration of wiring either

whats the best way to test? heat with torch and hit with IR temp gun? because if thats the case im good to go

 

[Diesel JD]

That sounds pretty right for a NA engine in higher altitudes like you have there in Idaho. You need a turbo

 

[jactoy4x4]

mine has never seen over 1100 and it roooolls smoke.

im not sure why you would hit 1300 even being in higher alt.

what is supposed to be absolute max for these? i figured running 1200 for more than a minute or so would melt em.

 

[Hyde]

I'm about 2000-3000 feet higher than you during most of my driving. I think 1250 is the safe max for a short time. I know I need a turbo, I'm trying to find an hx35 or a garret from a powerstroke.
