Anyone install an EGT sensor in their headers?
Thinking of installing one and a gauge in my empty pod on the pillar setup. Obviously I am only going to be able to monitor one particular cylinder so is there any single cylinder you would expect to be leaner than the others with a Superram?

Get the car running and look at the plugs. I couldn't tell you on mine - too much oil on the plugs to get an accurate read.

Step 1 :lol:
Right now I'm debating if I should have the injectors re-inspected/worked or if I should just purchase a new set and (hopefully) be done with it. I'm going to be forever nervous now with this set.

Re: (scorp508)
I had a similar experiance when I had my set worked on by those expesive folks in Decater Indiana. :rolleyes:
Instead of a temp sensor on the header, I use a hand held infared unit. There is some variation, but it gives me an indication as to what cyl to check. I'm sure Dad has one on the truck.

Yup, Raytec, believe the one with the laser, lower priced unit, around $105.
Believe I read somewhere cylinder #7 may be the lean one. This was before my diagnosis with Alhimer, er ah I forgot the name.
Are you waiting on the FPR?

Why couldn't it be further down the exhaust stream? Sure it might be a little cooler, but if it was consistently cooler you could still get the same effect. "Normal" might be cooler than if it was in the primary, but it would still go up and down.

Why not place it in the collector or Y-Pipe? My understanding on EGT's is its only really comparible to itself (Cant compare yours to mine or anything like that). So as long as its still in a spot that gets alot of heat your fine. I would suggest around the same place the O2 sensor is.
I plan on running two EGTs (one per bank) and mounting them in that location. (I will have 5 empty vents I can fill with gauges, so this will take 2, A/F in 3rd, other two undecided....)

If you take a look at dyno operators EGT locations, you'll see they're 1" to 2" inches from the exhaust port, consistantly. You get a better idea whats happening in the cylinder from that position. If you move the sensor farther down a primary tube you're measuring more of what's happening in the exhaust. A rich mix with retarded timing will read hotter further down a primary tube. Fuel burning in the exhaust. If you keep sensor position consistant you can compare readings.
I'm pretty sure you would loose resolution if you moved the sensor to the collector. Too much time for the exhaust to cool, plus cylinder imbalance would mess readings up.
VetteRacer282 - It'd be more interesting if you placed one sensor just after the exhaust port and then the other in the collector and put the guages side by side to compare. I'm pretty sure you'd see big, big differences at light throtle / cruise. That's where timing is toughest to tune and EGT's could really help.
