maximum exhaust temperature (turbo) ?

[STEEV888]

just wondering what the maximum exhaust temperature would get to on a turbo running 15psi at say... 7,500rpm for 10 seconds or so under load... or in general the max it would get to.

for eg, as i was not able locate a "plug taper" bolt for removing my egr pipe i was going to use a brass one.
Brass melts at around 900 degrees as compared to cast which is around 1200 degrees

soo if this brass bolt/plug melts its pretty much goodbye car.

i did some googling but could not really find a definitive answer as it varied from thread to thread.

ty's.

other options are steel bolts ofc but havent found one with the right thread.

Just for something to think about, VHT flame-proof paint (for headers etc) is rated up to 1093 degrees C

where is your egt located ?

Do you know what thread it is 1/8 npt im guessing if your looking at using brass.

Petrol or deseil?

Also if you have a egt port wouldnt you have a gauge hooked up

These guys have stainless ones

its for the egr pipe (the thing that takes exhaust gas and puts it back through the engine to cut emissions etc) not an egt which im guessing means exhaust gas temperature sensor ? (correct me if im wrong ive never heard of one of these).

and thanks for the link.

anybody else have a number for the temp ?

depending on thread that joint may have one anyway if you let me know what thread it is i got their catalogue and look for it . which car is this going on the 200sx??

[STEEV888]

you dont want to get much hotter then 750*c
north of that and you will start having problem
if its all running good you should be under that temp
if its for only 10 sec you would be around 500-600*c

sorry for not replying i eventually got onto nissan (a good person this time) and they have the part on order so in the mean time ijust filled in the old open bolt with liquid steel and drive it very nicely until i get the proper one. it has held up so far.
