7.3L EGT ???

[Hawkerhino]

what is the high limit on EGTs on 00 7.3 with intake and exhaust as listed in sig?

not sure where i should be worrying...

Try and keep your towing egts below 1250 in the manifold. Spikes to 1350 are ok but dont let them hang out their too long. I've seen a 7.3 on the dyno run 1350 in the downpipe and live! But i would not recomend this. Where is you pyro?

I'd just keep it around 1250 to be safe higher spikes are ok if you dont do it all the time. At the moment on my 2000 I have never hit 1k.

thanks for the answers, just got gauges installed and did not know what to look for.

Short bursts to 1400+ are fine but not sustained. It will take a couple minutes to heat soak the pistons, so if you are cresting a hill don't back down, they will qickly drop once you hit the backside. Although with proper tuning anbd airflow you shouldn't see this often. Mine will come right up to 1200 and not climb any higher, at least with coinditions I have put it through. It takes both of these to control EGT's. Just so you know average trans temps are 70-90 above ambient, the lower when unloaded and the upper when towing heavy. With my 6.0 cooler I usually stay at 60 above ambient when unloaded and 80 when towing my 10K TT.

What has been said is right and I do the same. The cool thing about having gauges, at least for me, is that if you are at the limit, you can ease off the throttle just a bit to drop the EGTs down under limit. I've done it a few times, especially on long climbs. It usually doesn't take much to lower 'em.

i have mine right after turbo how do i put it before turbo. Is the a write up on it ? what egt's after turbo it is 1.5in away from turbo right now

I just put mine in the left side ehaust manifold. if you look strait up when your under the truck at the rear of the manifold you can drill in and tap it out. Just make sure your in the longer part of the manifold so your probe doesnt hit anything when its all the way in. My egts at the down pipe ran about 900 after the turbo and when i moved it i could hit 1350 before the turbo. pretty big difference and the gauge moved twice as fast to warm up and cool down. its still nice to know what your temps are after the turbo so you know how warm the exhaust housing and stuff is.

sould i just put in anther egt gage or change it to manifold?
