Hi Guys,
I have been looking at some 160`s for sale here on RCU. I do not know much about the good and bad with these motors as i have been running 120`s only. Can the 160 be used with the same tailpipe as the 120?? Also what is the difference between the MKI and II types. What kind of updates are there for the earlier 160`s and do they hold up, i remember seeing they have to be run at a lower rpm than max rated?? is that true?? What is the latest version of the 160?? I heard a comment recently that JC may even stop making the 160?? oh well thats about it.
Thanks,
V..

Jet Cat P-160 are good turbines, updates are being done for better performance, I have the latest version and its been worked on at Jetcat. Bob told be that their should be no more problems with the turbine after the upgrade. The problem with mine had to do with the combustion chamber, wasn't performing well. Regarding the pipe I dont think you need to change the pipe if you actually use it for a p-120..

36 pounds of trust..IS GOOD...

Good Luck

It is my understanding that the P-160 has been temporarily discontinued for new sales in the US. I am pretty sure JetCat will continue to sell them outside of the JetCat USA territory. I am sure Bob will announce something when he and John get done touring the country (driving back from Superman).

I do know Bob is still supporting the motors, with the latest change being a 12 stick combustion chamber. They run awesome but I think are not economical to produce and support in this configuration.

As for the MkI versus MkII I will let Bob spell that out when he gets back from Superman. I am trying to find a good used one right now myself. I have 2 MkIIs and will put the new 12 stick chamber in when I get a chance.

As for some of your other questions.

Yes a P-160 can be used in a P-120 pipe.

All of the updates had to do with containment of combustion within the proper region, as the P-160 has very high exhaust gas velocity (VERY high). So with a P-160 it is much more crucial in terms of assembly, etc to get one to run right...there is very little margin for error. THerefore it was difficult to get the reliability up to the level of say a P-120. That is why they were derated in the US, in an effort to improve reliability.

Along the way these motors had new EGVs, modified bearing retention, and now new combustion chambers. There are/were more things coming down the pike if they ever re-enter the US market, but those things might go into some new motor, I am not sure.

These 10 to 1 thrust/weight motors are not easy to make!

Thanks Matt.

Matt,

So can I send in my P-160 to JC to get it updated to the 12 Injectors?
What is the diff between that upgrade and what i have ?
Does the entire Engine need to go to JC for such upgrade ( ECU, Pump, Selonoids, etc .. ) ?
Is Jetcat paying for this upgrade as well ? if not how much ?

My P-160 runs Excellent ( knock on wood ) with absolutely no issues whatsoever.


Johnny Hernandez

The I would keep running it, no need for any mods. Check with Bob, but if it is running it is fine..

really.........................

Hmmm, Matt that doesn't answer my questions.........

What is the purpose of this upgrade than ???

If this is important I'd like to know about it as I don't want to wait till it craps out. I've heard really bad stories about the 160 and I sure don't want to loose a Jet over something that could've been avoided.

I understand what you're saying about not fixing what isn't broken but I believe in precautions specially with this turbine that's been a hit or miss kinda thing.


Johnny Hernandez

Better talk to Bob then.

Upgrade/improvements (not trying to wordsmith you) are continual with JetCat....we did them to the P-120 for years (new combustion chamber, new ECUs,). The P-70, P-80, P-120 and the heli unit have all had improvements during production, the P-160 is no different.

Anyway talk to Bob, I am sure he can explain it better than me, and it is the cost of a phone call

huh !!


Your response there is kinda leaving me in a grey area, you allright there ?

Anyway, I will contact Bob and maybe he can answer my questions just for peace of mind or maybe someone else can ask away and maybe Matt will respond with more details.


Thanks .............. Johnny Hernandez

And by the way Matt,

sorry I asked I was under the impresion that you were involved with JetCat, and after all it is almost a $4,000.00 Investment.


Johnny Hernandez

HI, I talked to John Redman at Superman and he says Jetcat has some new mods comming soon for the JC 160 Mark 1 that will will fix the problem with the 160"s. I think he was refering to the new combustion chamber for about $600 to $800 dollars.
Rcpete

Thank you Pete,

That's all I needed to know, I really appreciate your response.

Now that wasn't too hard was it ?

Best Regards.............. Johnny Hernandez

Hi Johnny

I have a P160 MK2 that has been working also very well in my KingCat. Temps around 650 -660 at full power. I talked with Bob a while back and in his visit to Germany, JetCat found that a 12 stick injector aids in a much more stable / even combustion pattern. This apparantly allows for cooler / more stable operating temps as well. Although my engine is working perfectly I plan on the upgrade - if nothing else the combustion chamber will appreciate the difference. IMHO the P160 is about as maxed as it can get in thrust production. Any improvements that result in ccoler temps, more stable combustion ( even minute ) make the package better.

Hi Dean,

Thanks for your reply as well.
I agree with you in making things better, I guess we've been lucky with our 160's after reading and hearing a lot of guys out there having nothing but bad luck with theirs. I just dont want to wait for something to happen. I was bit confused cause Mr. Matt there tells me to keep running it when he claims to have a couple of them and will be sending them to get upgraded so it kinda contradicts his reply.
Anyway thanks again guys for the help I will be contacting Bob and schedule a day for me to send my 160 to get all the upgrades needed.

Regards................ Johnny Hernandez

GRRRRRRRRRRRRRRRRRRRRRR

wow Big D I've never seen you upset,

Well the way I look at it, I own 8 JetCats One of them is a P-160 and the rest are all p-120's so If I send my engine in for whatever they need; I expect service and good service.This is why I pay top dollar for what seems to be the best, if not My money is welcome elsewhere.

I bought a high end vehicle this yr and I was told that I needed to bring it to the dealership for all kinds of UPGRADES or UPDATES, what did it cost me ? a Phone call and 30 minutes to drop it off and drive away in a Loaner. That's good customer service if you ask me. I've done business with JetCat and good business was done, I expect they back their product up as most people do in their business, I know I do in my Business. We're talking thousands of dollars here so I assume its backed.


Regards.............. Johnny Hernandez

Ditto you on this one Johny!!!.

Johnny

Hey Bro I have now had 2 Jet Cat 160s so I have a idea whats going on.

Here is my take on the motor.

MK1 Size wise it's hard to beat same as the P120 and smaller then any AMT.
Spool up is a bit slower but with the big jets we have I don't think it matters because we usually spool at the latest on base leg.
Temps on the MK2 are about 200c cooler and that is a big plus.
Thrust on the MK 1 is around 34 to 32 lbs. MK2 measured at 35 lbs from RTI

Personally I am just going to fly the P160 like Matt said and not look for problems that don't show up.
I don't fly them but at 4 events a year tops and it should last a while.

Johnny I would upgrade your ECU to at least 4.9 Bro.
We going to see the SU 27 in Lake Wales?

Ian

Hi Johnny:
I am in no way saying that the service is not top notch at jetcat. I have received the same attention on my P-120's.

Dave R

Oh I know you have Big D, I know you get the service you need on your P-120's . The 160's another strory though from what I'm reading and hearing from everyone. We'll see I'm caling today and getting mine updated to the Max and play it by ear.


Yes Ian I'll have all the big Birds at Lake Wales.
