I am thinking of the EGT blanking plate on the exhaust manifold would be the best place?
Any ideas?

The sensor needs to be as close to turbo as possible, most good exhaust builders would supply a outlet in the correct location. Or you can have the correct size nut welded to the dump pipe near to the turbo then drill the hole out & connect the sensor.
Hope that helps

 pyrometer is that a Fancy name for exhaust gas temp ?

A pyrometer is a very high temp thermomiter. Pyros was the god of fire in one of those old civilisations

I have been told that it should be as close the the exhaust outlet as possible to get the most accurate reading.
That there can be as much as 200 degree drop between combustion and dump pipe.
At the end of the day though I suppose it is about monitoring the engines heat output so the figure is only going to be relative anyway.

When you get a proper dyno done they will put a sensor in so as to get the right egr, so when you take it in for the dyno and they do not egr it then there not doing the job properly.
They will put it in just under the turbo out let, have had that done twice now, why you pay big money for a dyno.
They did not do this in Cabooltue when we were there earler this year, other wise it would have cost us a heap more. So make sure when you have a dyno done you have a egr reading on the out put.

Hi Jimmu I'm new to your club from Cape Town - tried to post my details but it bombed out. Anyway, thats where I put in an EGT probe and where at least one of the tune up shops in CT does as well. It may not be totally reprisentative of the EGT but is useful if as you can remove the plate and work offline. My temp very seldom exceeds 650 C and only on open road uphill at full tilt. Have a look at what Steves auto clinic says about EGT measurement www.steves.co.za - they are the biggest diesel optimisation guys in SA and have quite a bit of info on Isuzu's |

I am not fitting it for the dyno tune. I want it to check temps in everyday use.
Thanks for that info Trooper. Do you know if any of the info on the ISUZU is on the website?
What have you done to yours with tha EGT or is that standard?

Yes, Steves has quite a bit on info on Isuzu's specifically power upgrades for the 2.8 and chips for the 3.0 , as well as info on EGT.
I put mine in myself to measure EGT, this is considered very important here as there are a lot of engine failures - may be due to the rarified air on the highveld (joburg) - about 15% less oxygen. A lot of guys tow caravans, which nail your EGT. cape town at sea level may not be so bad.
My engine is standard, but I am sure I am overfuelling. I want to fit a turbo boost gauge, with bleed for boost control. Any help would be welcome. I would fit a t piece in the air line from the intercooler back to the diesel pump. I think I could get more power from increased boost with current pump settings, but am not sure high high one can boost without comprimising the engine
