IM PUTING THE EGT TEMP SENDER IN THE EXHAUST BRAKE ELBO PORT HOW OFF WILL THE TEMP BE?

 

few hundred degrees, maybe more, maybe less. tap the exhaust manifold right by #4 for the best results.

 

About 200 degrees to be safe..

Are there any concerns with the thermocouple wearing and breaking apart with time and going through the turbo? I'm getting ready to install my pyro and was leaning towards placing it about 3" below the turbo in the downpipe. High temp range is 700 - 900 degrees there.

 

I put mine in the elbow also.

 

I installed one in the elbow for use with the turbo temp monitor/cool down timer.

 

You can factor in 100 degrees for each 10 lbs of boost.

 

Timber, been working in the diesel industry for 14 years now, never had a thermocouple come apart. i put my own in the manifold. right in front of my $1700 turbo

 

Yep, I have or will have both... Right now I just have post but when we pull the stock turbo in the next week or so we will be drilling right above the turbo...

I have 2 temp probes on mine. One is in the manifold, and one in the elbow post turbo. During idle, the post turbo runs slightly hotter (approx 50 degrees), but during operation and heavy acceleration, a good average is 200 degrees cooler on the post turbo probe.

 

what size is the port on the jacobes elbo

 

The whole point of having an EGT gauge is to know how hot the egts are, so why put it so far away from the source of the heat. They also say that any thing above 1600 degrees extended is bad for the motor and the probes are good to 2000 - 2200, so whats going to burn up faster? I will chance the turbo over the motor any day.

 

Thanks (to all), appreciate the input. I'll take the advice of someone who's had some grease under his fingernails over an engineer who more than likely, sits in front of a computer screen all day!

I've seen some posts where the hole for the pyro is drilled with dry, sharp, graduated bits and threaded with the turbo left in place, then vacuum & spin the wheel. Is this safe? Seems to be working.

 

if your going to ut it in the hole in the jake good luck getting that plug out of there it has high temp lock tite on it
