EGT Question

[PAYDIRT]

Does anyone know what the maximum temperature differential of the exhaust manifold, to the turbo (top of down pipe) ? I want to use the probe fitting at the down pipe, but I want to allow the correct adjustment for temperature drop.

if your gauge says its at 1000 your prob at 1200

So, assuming a 200 degree drop should be safe I just want to keep an eye on the egt's now that I have added a chip, but I don't do any extreme stuff, the truck is basically stock, I have to take it easy on the stock transmission. Thanks for the info !

What type of exhaust are you running?

There can be up to a 500 degree difference between the 2, why not just put it in the right place to begin with, the manifold.

I just installed a 3" down pipe and gutted out the cat, with a good flowing muffler. I don,t tow heavy or do any real extreme driving. I've installed the probes in the manifolds on my other diesels, but I was towing heavy. on this truck I just want to have a idea as to what the temps are with the chip. The down pipe has the probe fitting on it, so I was just wondering the difference in temp. I think 200 degrees is safe to assume, under normal driving.

[Jake]

But do you really want to just assume something when you have a $6500+ short block at risk?

[PAYDIRT]

Your right Jake !! I was just wondering if anybody had any solid numbers as far as temp differential.

Thanks

Thanks

RubberDuck at FTE did a comparison running a pyro in both locations, temp difference was between 200-500° depending on the right foot. Just plug the hole in the down pipe and put the probe in the manifold, no guessing games needed.
