EGT Temps

[skid326]

The truck I bought has a post turbo pyro on it. The guy screwed up and put the "pre-turbo" probe about four inches past the turbo on the downpipe
The set up is a BD Power Pup w/ Outlook monitor. The EGT's I am reading are low 400's cruising under no load and low 500's getting on it.

That seems awful low to me considering most people are talking numbers closer to 1000. Is it just because my probe is post turbo or do you think something is wrong with the probe itself?

Thanks for any input yall.

Thats exactly why...you should be seeing mid 700s cruising and high 800s to 1000 getting into the throttle for extended times...higher if loaded or towing.

You should idle around 300, cruise around 800 or so, peak out over 1k, but thats all pre turbo.

So does anyone know what post turbo temps should be?

yeah, I installed mine post turbo to begin with (was super worried about shavings), anywas my temps were very similar to yours, I had no tuner or anything. Under heavy load up a hil with a trailer the most I could get was 750F.

I moved the EGT sensor to on the driver side manifold and it is amazing the difference in gauge response now. You can actually watch increase and decrease on the gauge as load increases. Now under load up a hill the most I have hit is 1050F.

Your gauge is probably just fine, go buy a 1/8" NPT plug from the hardware store and start drilling and tapping a new hole in the manifold.

Mine cruising at highway speeds is 650 - 800. When I floor it for a bit it will get up to 1150 and that's stock and not pulling anything. Programmed I can hit 1300 in a matter of seconds.

Post turbo is fine.....as long as the probe is mounted as close as possible to the turbo itself. I have used probes in both locations and as long as you understand the temp differences it all works out fine. Mine is currently located only about 1.5 inches past, and temps are around 300-310 degrees cooler.

here is a link to some great installation instructions for EGT, tranny and boost.

At idle, wouldn't that make the temps zero?
