Probe position was actually going to be my next question. Is this a cast of drilling a hole, and welding a nut on there to screw the probe in?

drill and tap it

Thats what I did. Ill have pics up soon of the placement. Gonna clean it up and add the pics to my original thread.

A little bit of a bump.  ::)

All this talk of EGT's and after recently getting mine installed I wanna get my Eco pushin a little more boost. I know the wastegate is internal on the K14. I have literally scoured this site to find a decent pic of the screw that I need to turn to adjust it. I have gathered that there is a lock nut, but before I go tweakin on anything I would love to see a good pic with an explanation or an arrow pointing to the one that needs adjusting.

Thanks!

Hello good sir.

If you want more boost from a K14 you need to cut the metal wastegate line and put in a manual boost controller. Then you can just slip on some rubber hoses over the line and put the controller in the middle. You want the boost to be at 1-1.2 bar max. These hair dryers don't like much more :)

Thanks. I think I will wait than until the intercooler install. I just cranked the fuel back down to only being a full turn in, and it dropped the EGT's @ 70mph from 1050 to 850-900. Still plenty of pep and not blowin as much black.

A pic of this wastegate line would be sweet.

Unless you are wide open to maintain 70, this doesn't make much sense to me.

All this talk of EGT, I am wondering are you guys working all your temps in F? its just over here the uk its C and the gauges I have seen go up to 1000c

My temps are in farenheit.

@745 I do not have to go WOT to maintain 70. Maybe cause I am in fla at sealevel? On the way in today, 65mph ran at 800F. It was rainin some and the roads were wet so I run a little slower. Last night on the way home, 70mph ran at 900F.

If you are not WOT, then it takes X amnt of fuel to maintain 70, and you should do it at less throttle position with the same EGT regardless of smoke screw setting.

Rolling resistance makes a big difference, I recently took a 200 mile trip in heavy rain, and ran 1000F 14+PSI to hold 75MPH.
On the way home, it was back to 800F/9PSI at 80 MPH, and I did about 5 MPG better.
Apparently displacing water takes lots of energy .

I hear what you are saying but turnin the screw back a bit did lower the egts @70. I'm alsoo not comfortable at 75 or higher as the motor bucks sporadically a little bit once I start pushing it past that speed. When it bucks it also puffs dark black out the back.

Right I'm proper confused now...

My AAZ, running 8-9psi boost. only turned the fuel up a bit, but i get NO SOOT from the exhaust at all.

If I boot the throttle uphill, I can see 600 degrees CELCIUS in seconds, with no smoke? at idle, it's about 100 degrees C? you're all saying this is way too high?

I see about 350-400 degrees C at 60 on the flat, but this is in a small 4x4 (breeze block aerodynamics).


But the thing that confusesme is that I have No soot at all? It's an aircraft grade EGT gauge?

1. confusion is common here :)

2. Not all engines dump soot like a steam engine making heat on a grade. You are also not dumping enough fuel into your engine to make a steam engine load of soot with the amount of fuel you are running. If you have the need to do that, do the 2010 fuel mod.

3. they are hitting in and around the same temps as you, but with more fuel and more ponies available. Diesels are funny in that if they are too lean they get too hot, if they are rich they get too hot. So the trick is finding the happy medium.

4 no soot as you are running leaner then most guys here, and yes aircraft grade probes are the norm.

600 degrees Celsius = 1112 degrees Fahrenheit
If I bury it on a hill, I see 1200F in a second or two, and might creep to 1400.  I think the stock turbo is introducing a lot of heat at 1 bar.
No soot.

I also pretty much never cruise under 75 on flat ground

Thanks for the replys Guys, I'm just worried that I'm seeing such high EGTs with no gov mod and no soot? surely tuning this engine will only increase temps, and I'm already at 1100 degs F?

I understand that extra unburnt fuel increases temps, and a leaner burns is cooler on a diesel - I'm just worried about my temps  ???

How much difference would a nice free-flowing header/downpipe make? my current one (non-standard) is a little constrictive, at about 1.75" bore.

wheres your timing at?

retarded timing can cause high EGTs and make your turbo overspool..

my old engine would make 40 psi with a vnt, because of severely retarded timing..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.
