Noob question #3 EGT's...

So how many people have ran their EGT'S up either driving hard or towing uphill? I guess the real noob question I have is what happens when the temps are high and how Long do you have before something breaks?? any experiences??

Keep it below 1350 F and you should be fine. Some people say short spurts of 1500 F are fine.

From what I have seen, yes. Bearings/seals in the turbo. But really not good for anything.

By the time your gauge sender sees it your cylinder temps are already above that temp. Unloaded I have a real hard time getting to 1200*. Towing I can easily get to 1300* but will not personally run above 1250*. It's not only the turbo that goes but your pistons are an Aluminum Alloy. Melted and/or cracked pistons are the worry after the turbo is getting damaged. The sender needs to be as close to the cylinder as possible. Most of us don't pull our motors for the probe install so we put it in the driver side bend right before the up-pipe. Senders post turbo should never be allowed to exceed 1000*.

matt show him the one with the two different probes.

also beware that what the gauge reads maybe be off by as much as 100* depending on the quality of the gauge

12 physical inches apart (less than the length of the up-pipe between the port manifold and turbo manifold/collector), maybe 18-20 inches apart as the exhaust flows through the turbo:

Turbos doing its' job by eating all the heat it can take but you'd never know it with just a single post-turbo sender. I can heat my lunch while the students are performing their tests.
