D2 turbo removal

As speculation of the inexperienced seems to abound and no one with experience seems to be able to offer the correct method as it seems totally unfeasible..... I suggest you call your local turbo specialist and ask for their suggestion.

all the who har about where it goes i have come to my dissions after speaking to varoius diesel turbo experts in cars and trucks and upstream wins hands down with it in a position as close to the jucntion of manifold
i will take pictures and put it up in projects once its done so people can get a idea

What would be interesting, for anyone that has mounted theirs at the: "correct location is either the manifold at the turbo mount or the inlet of the turbo housing", is to mount one in the EGR plate and compare the difference. Its non-permanent and thus can be reversed. If anyone in Melbourne wants to do that, Id happily volunteer the use of my EMS-1 for the purposes of the test. That should solve the issue forever.

Alternatively, would a temperature "gun" be able to detect the difference, or would the metallurgy of the manifold mean temps are distorted?

I'm with Hamish & Strangy....;)
1. I welded a small and additional flat 4mm plate as a mounting point & drilled and tapped a 1/8th NPT through the EGR plate off the manifold so suffered no swarf contamination....BTW, there is a school of thought that swarf 'flakes' shouldn't upset a turbine wheel as they are designed to cope with chunks of carbon being blown through.....I personnaly believe that it is better to have FOD no where near an engines internals
2. EGT protuberance is exposed to the combined gas flow so I'm confident of an overall exhaust gas reading
3. I'm not chasing actual manifold temps hence my point about the turbo housing being a 'heat-sink'.....and yes, my infrared temp gun does show temperature ranges across the manifold/housing

Let's not over complicate a simple action here which is to obtain an exhaust gas temperature reading.

Many of the gas turbines I have worked on had multiple EGT's to monitor hot starts and pin-point an area of thermal overload, as did some of the high performance racing diesels I helped set up in Europe.

If you really want to be keen :twisted: - bung in 5 in line pyrometers adjacent to each exhaust port and 1 down stream of the Turbo as well as a Lambda probe to monitor your CO and HC emissions (Although they carbon up quick in a diesel), add in a TIT (Turbine Inlet Temperature) gauge and finally, a boost guage.

Then you'll be able to monitor each individual cylinder temp at the most appropriate boost pressure and keep an eye on your TIT while being responsible and green to minimise your carbon footprint :cool:

Come on - laugh....it's Thursday and we're all being too serious:p:p

3 points of note.....
1- what's FOD?????

2- protuberance??? Lol! Think you mean protrusion or maybe insertion depth!

3- TIT, well there's a lot of them here, a few big ones too I might add! :)

1. FOD = Foreign Object Debris...It's a common aviation term and you generally see signs alerting drivers to this at the entrance to the flight-line.

2. Protrusion and insertion....:o Whatever are you thinking!! This is a public form:p:p

3. TIT - see above:p:p

I work in an area where acronyms are so common place that after a while - conversation is like an alphabet soup :( much to the disgust of SWMBO
