Ok, I have been reading every post I can on this and would like to see if we could put together some sort of consensus for where the Boost sensor and EGT sensor should be located for the best accuracy. I understand that each of us has our own opinions, but I would just like to get input to see if I can formulate a general rule newbies like me can follow.

Pictures and time to install would be helpfull for all here.

Thanks for your help in advance guys and gals.

My opinion would be Boost sensor located in the manifold just before entering the engine would be most accurate.

EGT is more difficult however.... In one of the manifolds, somehow just right before the turbo, just after the turbo. I would think a couple of inches before or after the turbo would give the most accurate reading of turbo EGT's.

There is so much a gap in readings because there is so much a gap in locating. In the manifold seems it would give the highest reading, but you are only getting one side....and if that side runs hotter, or cooler for some reason???

I value all your input on this people.

you shoudl check out the do it yourself section..there are pictures, how-to's and everything.

best place for boost is on the manifold as that will be most accurate. there is someone on here that makes a rubber manifold boot that replaces the stock one and it has taps for boost guages. Its the easiest way and no drilling required.

The pyrometer (EGT tap) should go on the passenger side manifold BEFORE the turbo. You want to know there is a problem before it blows the turbine or melts the impellars. This is also in the do it yourself section with pictures as well.

good luck

Thanks, I have been there and come away wanting to get a concensus, there seems to be more going for the pass side manifold, but there is concern about the pyro getting too hot and melting, and I do not believe that a temp reading there gives a true representation of the EGT tempature as it only reads half of the engine. You guys have to remember I am a serious AAAA member and that just was not enough information for me. Besides, it's just not accurate enough for me :D. Maybe if you could tie 2 pyros in each manifolds together for a averaged reading. And before someone says it, Not going to 2 guages, unless maybe I did one in the manifold and one post turbo. Hmmmmmmmmm

Seems to me turbo temp is what were concerned about anyway right?? so why would you want to know the EGT 2 feet before the turbo??

And NO, I would never concider putting a hole in the turbo...Not that crazy....yet...:lol:

john, passanger side is easy to get to and most everybody uses that location, so that makes it easier to compare readings. probes wont melt if you look at dyno engine testing you'll see pyro in exhaust coming out of cylinder and on large stationary diesels normal option is pyro on each cylinder along with bank(end of manifold) turbo in and out. i also use SuperDiesel intake manifold which is post intercooler reading, but if you get interested you can tee into wastegate feed line(oops, you don't got). got juice has got what sounds like bunch of gages for testing, in truck you can overdue it. if you look under aircraft supply you can find dual pyro gages(1 gage - 2 pryos, and switch for cylinder if you want),wicks aircraft supply or aircraft spruce & specialty co. are a couple.
hope this helps you

Westach makes a 3 channel Pyrometer if you need to be that anal about it.
You could set up a post turbo then each cyl bank.

For anything else contact DAVTRON if you need specialty stuff.
Believe me, they have the goods on that stuff. FAA Spec +/- 3% gauges... wow.... but a bit on the $pendy side... although if you go through a reseller their M/U is 50%!
Direct works better!

Sounds like you want max info. There is a high cost to that....like the man said.."How much do you want to spend? TIT and TOT are inputs from turbine inlet and outlet...(trubine inlet temp, and turbine outlet temp) monitored by pyros in the respective locations. EGTs can be monitored at each cylinder if you so desire with a computerized system that will give you the information as you select the format. These are as mentioned above aircraft engine aplications, but easly installed on a diesel engine. Again, all it takes is lots of money..........To monitor two sides would be simpler...with a 2 position switch, manually operated...or shop the aircraft supply sites for a scaled down version of the computerized system.
