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 ;~)

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...

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.

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! Last edited by ForcedInduction; 05-23-2008 at 10:48 PM. |
