How hot should turbo housing get?

[omy130]

Unsure how hot the housing should get? It gets untouchable when @ idle & after a short blast up the road, it's radiating so much heat???

There is good oil output in the feeder line. Now all over the floor, container split :(

This turbo is untested. It came with a complete motor & while I was changing the manifold gasket, I thought I'd wack it on to see how it when.

The thought behind the turbo change is that I'm not happy with the cars' top end speed/power. The gasket being rooted was a hunch based on oil present & a intermittent high pitched squeal that has just showed up recently.

Car is a 93 Defender 100 with a 200Tid.

Things get too hot to touch at about 65 degrees, so if you're unsure you will need something that can read high temperatures. Others will have to advise what temps, but you're looking at hundreds of degrees.

G'day mate.
Your turbo exhaust housing will get very very hot (hundreds of degrees) after a short burst of throttle.
It is after all essentially full of exhaust gasses that were fractions of a second ago an explosion even at idle.

Iding EGT is ~150 deg C

at full noise in theory if I didnt back off and wound the fuel screw in hard enough and abused the boot badly enough hypotetically I could push the turbo temp up to around 1400 deg C unfortunatley the pistons would have melted away or the head let go at around 1000 deg C.

I've seen big cat engines on the dyno before with turbos glowing red, I'm sure a little turbo would get FH as well! They can handle it.

Have never really paid attention to the heat before now. I've always been a cautious mechanic when changing things. EGT temps rose to 500 with boost at 14Psi at the inlet manifold. The turbo housing sizzled the skin and the head was a touch cooler.

your missing a few PSI of boost (to the tune of 16 if you want to bench mark agaisnt my disco) and about 150deg C of EGT
