Post your EGTs
 

Those of you who have a pyrometer please post some EGT readings. Please include engine type and body, pyrometer location, driving situation, and modifications.


617 Turbo w/ stock T3 turbo in a 240D/4 speed stick, Pyrometer pre-turbo

Stock (from memory): 600* F cruise at 65 mph, 500-550* F around town, 1100* F highest seen after long 4th gear pull up hill

Air/water intercooler installed:

475* F cruise at 65, 400-450* F around town, 950* F highest seen, 750* F after 0-60 run

EDIT: now that I have fixed my boost problem I an at 450* cruise at 60, 650* after a 0-60 run and can not get any higher than 850* on a long, full load pull.

Intercooler+GT2056V turbo: 425-450* F cruise at 65, 375* F around town, 650* F after 0-60 run

617 Turbo w/GT2256V in a 240D/4 speed stick, Pyrometer pre-turbo

W/Intercooler:
600*F cruise at 70mph, 600-900*F around town, 1450*F highest seen before I lifted off, 1200*F after 0-60 run.

Some interesting tidbits I found:

Bluebird Wanderlodge CAT 3208 with aftermarket turbo. Pyrometer pre-turbo. 1100 degress on a steep long climb under normal conditions. Same climb with a dirty air filter 1275 degrees.
With clean air filter on a flat road at 65mph it runs around 600 degrees.

You need to re-plumb that thing with an air-to-air aftercooler Kerry ;~)

"If it isn't a CAT, it's a dog"

Thats a chilling description about exhaust valve creep, Forced... I think I won't be pushing anything over 1200 for any amount of time thank you very much...

pre-turbo sensor W/ big A/W IC, no rack limiter, GM 3.8 airbox, T3-45@16-20psi:

highest ever: ~1050°F WOT, loaded down, up a hill for about 5min
around town: 450-650°F
highway: 650-850°F (depending on speed and grade)

I bet with no rack limiter if I found a way to lug it down around 2500rpm WOT I could get it to make higher EGTs, but the way it is it just aint happening. I'm sure they will go way up when I make it rev 5K+ and crank the TC...

Isn't that why they are sodium filled?

OM 617 300SD Rack Limiter removed, straight pipe back, pyro pre-turbo, boost at 14psi
450*F cruise around town
500*F highway at 65mph
750*F highest seen after a pull to about 90mph on a slight incline

I have a 190d with an om602 turbo.

Pyro is pre-turbo where all the pipes of the exhaust manifold collect.

Boost set to about 14.5-almost 15 psi.

1 1/4 turns for the full load screw. Alda leaned out to the max and still smokes a lot off boost. No excessive smoke under full load.

My egt gauge starts at around 900*f so in normal driving conditions I never see it move. It'll get to about 1200*f at the top of 3rd gear (~5000rpm ~120kph) if I do a fast standing still start.

At around 140kph in 4rth pedal to the metal (4rth pegs out at 160kph) it's at about 1200-1300*f and climbing fast. That's where I lift off.

'84 617.952, no rack limiter, stock turbo, stock exhaust, big A/W IC, DN0SD265 nozzles @138bar, timing 26*BTDC, COLLAR GROUND OFF THE DELIVERY VALVES

EGTs: climb to 1100*F in no time flat. Like, 1 WOT pull from 0-80 (which takes around 30sec, maybe less). This mod really works. need more airflow!

a smidge off topic
 

So if a fella is wanting a EGT kit, Gauge,sensor etc....
What is the cheapest, good, reliable one?
I'm thinking of installing it in one of the central air vents (boost gauge in the other) so sized appropriately for that location, and while I am skating on off topic ice, what do you guys like for a boost gauge and installed in that location?

I used the gauge and sender package from here: http://www.egauges.com/vdo_mult.asp?Type=Pyrometer&Series=Cockpit&Units=E

and the 30 PSI boost gauge: http://www.egauges.com/vdo_mult.asp?Type=Turbo_Boost&Series=Cockpit&Units=E

They are a close match to the factory gauges.

Thanx buddy, Those will look great! I placed my order with them.

Not for me. EGTs go through the roof in a heartbeat.

Here is a video just going 65-80mph. I couldn't get a 0-60 since I was up to 1250*f by the top of 2nd gear!

Wow. You have been running high EGTs all along right? Get that WI system up and running!!
