Post turbine egt?

[hamradio]

Finding a good spot to tap out my VNT manifold is proving to be a minor pain, plus I only have a little 5/8" long threaded thermocouple; I plan on upgrading to a real egt probe in the future.  

How well do post turbine egt probes work?  I'd be much more comfortable tapping out my homemade downpipe than tapping my manifold, at the moment.

How well will a thermocouple sticking maybe 1/4" into the exhaust work?  What if I put it in an elbow, so the exhaust coming out of the turbine is going straight at it?

Would the short little probe even work well in the manifold?  What if I placed it directly after a cylinder?

And last, on a boosted na, what's the max egt post turbine?

Thanks.

eeeh, post turbo EGT makes the gauge move so it looks like your measuring something.  That's about it.

If you have K type thermocouple and gauge, toss the one you have and get this puppy:

Stinky fast, and deep insertion length.

The diesel world wide rule of thumb limit (sustained) is 1300 Fahrenheit PRETURBINE.

Excursions above that for short periods are OK.  How high and how short?  Its hard to say.

I've seen 1500 for about 10 seconds a wack on my 1.5TD, backward pistons and all, and found no piston damage when I popped the pistons out to correct my brain fart.

I suspect that you should be able to get enough booste to keep your EGT down, and still get very impressive results performance wise.

just ordered it.

sorry for hijacking your post but will that work on any gauge. Then you need what kind of wires?


also 1/8 or 1/4?
