EGT Survey ZD30 DI/CRD


Recommended Posts

OK, just in case, I would like to get my EGT survey thread up and running here as I think there was a lot of good quality info in the other one for new and old members alike. I looked at bringing the info across but I only own my info so it may not be legal and there would be a hell of a lot of sorting to get it right.

If you are interested in keeping this going please use the structure below in a cut and paste form and add your info over mine.

There always seems to be a question of where and what EGT temps are acceptable with the GU ZD30 motor and with EGT being so critcal to the longevity of the motor you can never have too much information.

The position of the EGT sender, ie pre or post turbo, the distance from the turbo dump pipe flange, the temp range you experience, cruising, towing, city, give others valuable info. Also add whether DI or CRD and what brand gauge is used. There are other aspects which may effect EGT which I have added as well. Fuel eco, well thats just so you can brag or squirm.

Here goes, it will be a WIP.
