egt temps?

[SEmerson]

I just installed a pyro and i can get 1250 just running empty with hard ecceleration. Isnt this high? what should i see? and what would be too hot? I put the sender in the mantifold to one side just be for the turbo flange.

If that temperature is at full throttle in high gear it's probably about right,you didn't mention how much the truck is bombed but if it is 1500 is very easy to reach in the higher rpm range. Try not to exceed 1300 for any length of time and you'll be fine.

Temp.

I have mine post turbo so it reads lower than pre. turbo but I can reach 1000 or so under hard acc. in upper gear, so yours may be pretty close at 1250.

to me that sounds pretty close to what I am seeing on my wifes truck. She has a 2k1. 5 Auto, when I decided get off of my butt and install gauges on it, I replaced the stock airbox with a K&N RE-0880 and also replaced her stock peice of junk Hy-35 with my stock HX-35.



Max she can reach now is 1200 degrees.



So my honest advice is to do exactly what I did. Take that stock airbox off and trash it, then seeing that you have an auto, you should also have an HY-35 turbo on your truck. Call Piers and order one of his new tricked out HX-35's. It will not only lower your temps, but it will make your truck run a lot better.



Just my $. 02

Max Reading Post Turbo?

My pyrometer is mounted post turbo. I can regularly get 850 degrees empty going up a long grade in high gear (6th). What is a safe temperature to run for extended times from a post turbo pyrometer? Can I let it run at 850 degrees for extended periods (post turbo)? For some reason I was thinking 800 degrees was the max I should let it get to but it will easily go above that. Engine is stock.



Thanks,

I do not know what my temps were stock. But with the current setup (see sig) I can't get it above 1150° with the truck empty. A couple of weeks ago I was hauling a 8000# load while following a semi at 45 MPH up a steep hill in overdrive (lugging at about 1100 RPM) I noticed my EGT at 1350° . I then turned off the overdrive and the temp came down to 1100°.



I have the stock HY-35 turbo, exhaust and airfilter. I've found that the more air I put through the motor the cooler it runs. with an 8000# load at 80MPH, in overdrive, up a steep incline at about 2300 RPM my temp usually runs at 1150°.



PS: my pyro is pre-turbo. .

What temp do we melt at? Also I taped the mantifold by the turbo flange but to one side. I wish i would have taped it in the center with the sender droping in to the turbo. Any thoughts on this? Where did every one else tap pre turbo?

The link should point to a photo of my truck's pyro tapping location.



I believe the concensus for maximum pre-turbo temperature is 1250-1300 degrees for continuous running up long grades. The iron won't start to heavily oxidize and pistons won't melt until 1500-1700 degrees -- but even then, only if the temperature is sustained. The BIG diesel dragster trucks hit 1500 degrees going down the 1/4 mile, but don't stay at that temperature for very long!

What's normal

I just traded a '99 auto for the truck that I have now and the new truck behaves differently than the old one did, so I need opinions from others as to what they are seeing. My EGT probe is installed exactly like the one in the picture above and it seems to me that the EGT's will drop off to 250* much faster than the '99 would. It also seems that they will climb much faster too, but so far they don't seem to go over 900* on hard acceleration up to about 75 or so. The '01 is 100% stock right now (Other than the guages) so I'm just wondering if these EGT's are supposed to be higher. I'm going to try and hook some weight to it this weekend and see how it pulls.



Thanks,

Mike
