Can anyone tell us, how hot should the turbo temp be running at?
We have a GQ patrol with a denco turbo and as an example it's running at 320 degrees at 8psi boost- that's at 90 kph without towing.

My Navara runs at 590 after turbo, on a dyno under load,
Pretty warm eh!
Dunno what it does on a real hard pull up
hill, but then again thats what gears are for, !.
On our last Desert trip, loaded up towing a camper, hard going in in bulldust, and sand, and the turbo whistling like hell, I would hate to think what temp she got to.
But I will put it to you this way, I kept boiling the 2nd battery.
Cheers MAte

Gday
There are many inputs into the equasion as to whats safe...if you run an efficient intercooler, the temperature of incoming air is alot less,(60 degrees on boost) so theoretically, the exhaust temp can be higher before it effects the piston as much as if you didnt run an intercooler, and inlet temperature was 200 degrees celcius.
The 550 post turbo may equate to 750 pre, or it may be more if the turbo is water cooled, or less if it is larger than the factory setup...there are just so many vaiables...ive heard 600 pre turbo, and will stick to that until i get my intercooler plumbed up.
