ZD30 DI Turbo EGT

[BillsGU]

Can anyone tell me what temperature THEIR pyro indicates when cruising at 110 kmh on a flat section of freeway for a period of time (say 5 minutes)? I have looked at many sites and asked many "experts" and have not had the same answer twice.

Mine sits just over 400 C and increases slightly when going up slight hills and drops when going down hill.

What does YOURS indicate?

I have just fitted the NADS, before it would sit on 420 to530 when pushed and towing. now doesn't go over 220 deg C no matter how I drive it. highly recommend NADS. all temps are in C

Is this at 110 kmh? Also, at that speed and temp, what is your boost?

Have only just fitted it and still adjusting, dont know if my truck is a freak but temp at 110kph is 200 deg C , pushed it doesn't move. Very happy with that, boost is 10 psi, fitting a needle valve next week as well. Before NADS fitted temp was420-530 deg C, EGR blocked as well, X2 HIGHLY recommend NADS

Mine sits around 230 - 320° depending on the wind/load/ambient temperature, typically around 290° . Boost around 10-13 psi again subject to wind/load/temp. Climbing hills at that speed can go up to 450°+ so I don't like to push it that much I normally back off at 500°
I don't have it stock anymore.
Cheers

Re checked as plumbing was wrong ,@110 it sits on 220C- 250C on flat run no load 10 psi and goes up if pushed hard 450C-500C tops, and settles back quickly

OK - thanks guys for your input. Good to compare what others are getting.

Mine sits at about 250deg while cruising at 110km/h, thats at about 5psi. It will rise to 400-450deg fairly quickly with a decent hill.
My probe is in the engine pipe, about 50-75mm from the flange.

I have been getting very similar results. I have just replaced the head with a european non-genuine number which when compared to the original was much better engineered and about 50% heavier. The old one perforated.
I find that the temp flies up quicker now, is that a tuning problem? Can it be sorted?After the change over I noticed a leak on the induction side when boost pasted 10 lb, it was due to a bolt that had dropped out of the EGR valve, ie I didn't do it up tight enough. Intercooler had the smallest of leaks which I fixed from the inside by cleaning the surface to buggery and applying a very small amout of silicon over the crack. BTW if you want to test for a leaking intercooler get a bicycle tube and cut it on the oppostie side from the valve. Place to two open ends over the inlet and outlet of the intercooler and clamp. Inflate to desired pressure and listen for a leak. Saves you having to hastle the radiator bloke and your car is off the road for 10 minutes as opposed to all day.
