Max egt??

[matty21]

what should i be watching for my max setting? right now its set too 1950 . im using the H&S egt sensor location

What kind of temps do you usually see? When your tuner is on hot do your EGTs get really high or stay where they need to be?

So, do you have install a probe on the 6.7?

idle is around 350-400ºF
average hwy speed im seeing ~700ºF .
on a full throttle run too 100mph the minimax de-fueled at 1450ºF so i raised the setting to 1650ºF, tried it again, still de-fueled so i raised it to 1950ºF and it didn't trip . then i brought it down too 1750ºF and it hasn't tripped yet. i dont know if the H&S probe location is pre- turbo or post turbo. its mounted here shown on steps 4 to 6 http://www.hsperformance.com/images/fordegt.pdf
and here in step 25.

It appears that your probe is mounted where the exhaust from the manifold enters the EGR cooler. If this is the case, then your probe is pre-turbo.

Has anyone out there installed a EGT probe directly into the manifold on the 2011? If so, how did you access it? I just started a thread requesting this info. I have a stock 2011 450 work truck, that needs a pre-turbo egt probe.

Nice Hijack, YTEP_F450

Still no answer on normal and max EGT levels for this set up?

Not yet but the NOS kicks it down 500 degrees. But I should mention I see coolant temps around 230 whoo hoo

normally you woudnt want to exceed 1350 for sustained periods, as aluminum melts at about that, but I have seen many trucks run hotter than that.... anywhere pre turbo will be pretty close to what you see out the manifold, the further away from the exhaust valve the cooler it will be.

Hey Matty, does the H&S not have a display screen to show real time egt's, or are things just happening too quickly to watch it? Either way 1650+ egt's are pretty darn high. I do not know if it will affect anything for a short burst, but man, I would not stay in it too long at those temps. I know you have a large 5th wheel and a gooseneck, definatly wathc your egt's towing or de-tune. I am sure you already know this, but just making sure.

Aluminum does melt at around 1350, but the oil jets below the pistons keep the pistons cooler the the actual cumbustion temps. You are still running on borrowed time if you keep the temps too high though as the pistons will start building heat pretty quick even with the oil jets.

We are running Spartans 165 everyday on my dads and his EGTs stay about 600 on normal driving and about 250-350 at idle. When we romp on it it'll hit about 1450 which is where we let off, easily doing over 100 by then
