Pyrometer Install

Posted

So i have everything wired up, gauge, amplifier, probe. The only thing I have left is literally the power and ground. I spliced my power for all my gauges into the dimmer switch, but what have you guys spliced in for power for the actual pyrometer? I ran out of time yesterday and literally I was at the point of "eeny meeny miney mo."

 

Any ideas that is a good 12v key source and not hard to get to?

Go to genos garage and they have install pics. There is a wiring harness below the drivers side of the dash that has a power and keyed wire. Cant remember the colors

Finally got my pyrometer installed. MAN WAS IT A PITFA to tap the manifold!!!!!!  I actually couldn't get it tapped at all for a long time!! I got the engine hot, tried it, no bueno...tried using a heat gun on the surface, still no bueno. I even put ice on it thinking if I make it harder then the tap would grab....still nothing but pissing in the wind. I finally broke down went to the auto parts store and bought another 1/8 NPT tap and BAM!!!! It worked like a charm, stupid *** tap was more dull than I thought. After about 3 seconds it grabbed like a boss and started my tapping procedure. I got the power and ground hooked up and I absolutely love this gauge. New to me in the sense I have never seen one work except for CHT gauges in a plane.

 

 

After driving for some time yesterday and today I found out that at idle my EGTs are between 300-325*F at idle and at 70mph it will fluctuate around 600-700*F. I even tried to get the truck above 1100*F and I barely made it there at WOT from 50-80mph 6th gear pull. I mean it barely made the very tip of the yellow on my gauge, so I assume everything is working like it should be on my truck. Thoughts? Is this all normal?

Sounds fairly normal to me. Idle might be a little high but maybe not. Thats about where mine runs with the 40hp injectors. All sounds good to me!!

Well it will go under 300*F at idle if I let it stay there long enough but it takes about a minute.

How would I tell if I had aftermarket injectors, do they keep the EGTs higher at idle?

Idle usually doesnt change much for EGT's between injectors. If you could barely get up to 1100 degrees at WOT then I would safely say that you have stock injectors. Even just with my 40hp I can reach 1200 at WOT pretty easily.

Well as long as my EGTs are normal I am happy. I don't know the history of the truck but it feels like it has stock injectors.
