Thread: EGT & Turbo boost gauges for td5

Wonder how high do the EGT need to be to make the manifolds glow, or is this caused on the dyno by lack of airflow. looks to be pyro sensors all over this

[ame=http://www.youtube.com/watch?v=cSPM1KxONAk&feature=player_embedded]AMG 5.5-Liter V8 Biturbo on Test Bench - YouTube[/ame]

edit, I just found this


400 Red heat, visible in the dark
474 Red heat, visible in the twilight
525 Red heat, visible in the daylight
581 Red heat, visible in the sunlight
700 Dark red
800 Dull cherry-red
900 Cherry-red
1000 Bright cherry-red
1100 Orange-red

C= Centigrade


Wow - that Merc engine must be around 1100 C,
I dont like going over 700, meybe I'm being a little conservative ??


.

What should the egt temperature be for a td5 anyway?

Depends on the map used.

When I'm towing the van, I drive by my boost gauge and EGT. Thru gears, I'll give her the berries and pull 20psi boost and EGT's respond accordingly, but, when cruising, I drive by the boost, when in 5th, I try not to exceed 15 pound and if I need too, I'll drop back a gear or 3. This keeps my EGTs under control and not laboring the 5th cog and results in a 90 to 100 km/h speed depending on weather conditions. Seems to work for me. The van is 23ft and 2300kgs. My boost gauge is an Autometer and EGT is a digital Cruzpro.

your EGT temp is guided by the total heat soak capability of the following

1. The piston crown
2. the head
3. the cooling system
4. the lube system

you can only run the engine up to the weakest components ability to deal with heat.

For stock ally pistons with basic splash oil cooling that pretty much sets your max sustained EGT at 650 degrees (pre turbo EGT)

Which model have you got?
They have one that does both egt & boost.

I had one of Ian's Thermoguard units in my Nissan Patrol ute for a few years. Excellent piece of quality gear, but compared to some of the units around now it is lacking in features. I must check the link out because if he's added to the features, like having alarming functions, I'd consider buying another - if the Puma has some real-estate on the dash out of direct sunlight.

-the basic one with the k type sensor, on ebay for $102 + $18[usa] postage, i run an analogue vdo psi 0-30 guage for boost
