RE: Kingtech K-180
 

2mm? that seems a bit shallow. Is that standard for Kingtech?
Scott

RE: Kingtech K-180
 

We used to suggest 2 to 3mm into the cone, but according to Gaspar - 2mm is all it needs.

RE: Kingtech K-180
 

Curious, Ive noticed other brands being nearly 1cm. Wonder what really is accurate?

RE: Kingtech K-180
 

Thanks berry mine is fine just like it is, I just wanted to know for product knowledge and if I ever have to send mine in for some reason its nice to have the option

I may upgrade it after the 1st 25hour since I could use the extra punch when I put the wing stores on the F-16 :D if I dont sale it at KY jets

RE: Kingtech K-180
 

What is accurate is to operate in accordance to the manufacurer. On this note, when I was running my P60, I can't remeber anywhere near 1cm, we're known to be one of the cooler running engines not because how deep the probe sticks in but how much air is blowing through for the given heat generated by the chamber.

RE: Kingtech K-180
 

Just an observation regarding probe. But what data supports the claim of being cooler running engine? There are two Kingtechs listed in Performance Comparisons in Jet International and its not really supportive of that.
Im not critizing the brand, just a curious question. I honestly dont really pay too much attention to temps, or care for that matter, but i dont think i ever recall seeing a 780 before. But if its supposed to run at 720 and the fix is to pull out egt 1mm, then I guess its that easy! Ive never messed with my egt's except when I owned RAM back 12 years ago.
The probe depth is obviously a variable of temperature. Obviously not a standardized location or installment.
The pic below shows over one centimeter of egt inside tailcone, but it is bent and laying on tailcone and not probing into exhaust air. i dont know how the kingtech egt is installed. Maybe they are easily bumped and moved.
Just making an observation that: could it be possible that the MAX EGT numbers are just a reflection of EGT location or depth?
I dont really give a crap if it runs 730 or 780, but Im sure it plays a significant role on turbine life. A different brand might be running hotter, but could it be the probe is just further in?
It clearly states in Jet Internationl magazine in Performance Comparisons regarding MAX EGT that "Exhaust gas teperature is nominal as the actual EGT varies substantially depending on the exact position of the sensor"
So how can anyone claim a cooler engine when you just move the EGT?
Scott

RE: Kingtech K-180
 

I thought I already explain the high temp. Its easy to tell an engine running with high temp.. the tail cone glow orange at full power. this engine don't

Are maybe I need to do another video?

RE: Kingtech K-180
 

The data from Jet International reflects to our records and I think it does support...

RE: Kingtech K-180
 

Scott, KingTech isn't flawless by any means, as we had our share of growing pains, but thank goodness temperature hasn't been one of them.

I'm pretty sure if one sticks the probe in further than manufacturer suggested, will get a hotter reading, likewise, if you pull it out some, cooler it reads. Why there's such a difference in the depth of insertion between brands?? Perhaps types of probes are different? or perhaps ECU auto compensates for the final value based on set up? As far as with Gaspar Xicoy ECU, it requires 2mm to be inserted into the cone, and I remember Jet Central manual also concurs at 1/16" to 2mm, that's 1.6 to 2mm.

Here's something from Gaspar's manual that could be found on our site:

4.4 Thermocouple
The FADEC use a thermocouple of type " K ", apt until 1100ºC. The provided standard thermocouple consists of a wire of Inconel of
1.5mm of diameter finished in a connector who fits directly on the FADEC. The recommended installation consists of practising a drill of
1,5 mm in the exhaust nozzle of the engine and inserting the end of the thermocouple so that it be 2mm within the flow of exhaust
gases. Because the sensible zone to the temperature is the end of the thermocouple in any case DO NOT CUT it since it will be
destroyed. Also, do not bend it with pliers or other utensils that cause very acute angles of curvature. The installation is due by
hand and the curves must have the greater radius possible. In principle any type of thermocouple " k " can be installed, but it is
necessary to consider the thermal inertia of it, since the temperature of the engine can raise much quickly that the one of the
thermocouple and cause not controlled situations of overheating.

Anyways Scott, I think you raised some very good questions and comments, perhaps one day we could have you to run a KT in one of your many beautiful jets ;)

Cheers,
Barry

RE: Kingtech K-180
Barry,
Thanks for the thorough explanation and excerpt from gaspar manual.
I've honestly have not heard anything bad about king tech and the brand seems to have a good following of happy customers. I've read numerous threads regarding you and your excellent service.
I'm not taking a jab at the company. Im just noticing that the placement and installation of egt seems to vary from each manufacturer. Has me curious as to "what is really correct and why" . Then this made me question all the numbers listed on the comparisons chart(all of them). I had never considered this number being so subjective. Then the disclaimer about egt location.
I have come to kingtech defense before in past as they actually hit advertised specifications. Although I thought saying it was a "cooler" running turbine might be an aggressive statement, seeing that egt placement seems to be a critical variable.
Seems to be a giant battle in such a small market. First to last separated by microns.
When the comments came up earlier in the thread about temps and the egt probe location, I looked at some of my motors and the depth of egt, thus the inquiries.
I see now that some brands have 2mm, while some are 10-12mm. seems to be pretty significant. It may simply be a different style egt.
With a good warranty, I guess temps aren't super crucial.
I learn something new here all the time!
I appreciate your response!
Ever thought about changing the aesthetics? Definitely has brand recognition though.
Best Regards,
Scott

RE: Kingtech K-180
 

If same combustion chamber and injectors, how can fuel efficiency/consumption improve?


Mav

RE: Kingtech K-180
 

I guess because other 180 class engines run a higher RPM to get the same power. Just my opinion but I could be wrong

RE: Kingtech K-180
 

Not quite, both 170 and the 180 have the same peak RPM as well as throttle curve. After reviewing more data from the factory, at full throttle 180 uses only 20 to 30cc more than the 170, perhaps for the thrust difference 180 offers slightly better efficiency...

Just when you think KingTech is Golden, think again...

RE: Kingtech K-180
 

It's now red hot!
This one is for you Scott :D

Hey hey hey! My color!!! Lol!

RE: Kingtech K-180
 

This one is for the futura :D

RE: Kingtech K-180
 

hello Guys, more reviews about the new K180?<div>
</div>

RE: Kingtech K-180
 

My k-180 runs great ;) frankly speaking too much power for my application right now [&o]

RE: Kingtech K-180
 

We bought three kingtech engine.(K-180G.X1, K-140F.X2,)

My k-180G is so cool.:)I look forward to his power to show.:D
