P-160SX thrust pipe
Hello mr Matt.
I just have ordered the new Ultra Lightning together with the P160SX.
It should be a great combo I suppose.
A friend already has the UL and we are not impressed with the deliverd thrust pipe.
It is a straith 3.35 inch pipe and way to heavy.
We want to replace it into a titanium pipe and would like to know if we get more "punch" if the pipe is converging.
Thanks!

RE: P-160SX thrust pipe
Hello,
Generally speaking, a converging pipe will provide more thrust at a higher airspeed (higher efflux velocity from the pipe). I like high airspeed so this is usually what I use.
A divering pipe will do the opposite, providing more thrust at lower airspeed.
I am not sure if you are running a bypass (I do) but this has a large effect on the pipe design. I wish we had some sort of adjustable pipe, but we don't (or at least I am not aware of one), because this experimentation can get expensive (especially with a Ti pipe!!)
In the end the temperature of the turbine is very imporant, you want nice high EGTs in the flight regime you are interested in. If the bypass/pipe is pulling the EGT down (by creation of low pressure aft of the turbine) you won't be getting full power from the turbine.
Hope that helps,

RE: P-160SX thrust pipe
Hey thanks matt.
Ofcourse I'm going to use a by-pass. I think aerodynamicly speaking it is much more efficient.
You mention to adjust the pipe or to adjust the distance between the nozzle of the turbine and the pipe to get higher EGT.
What kind of EGT readings do I have to expect to get the maximum power?
I readed somewhere that the new SX can be set to higher rpm to get 38 lbs, is this true and is the warrenty still valid?
Many thanks again.

BUMP.
I am very interested in the answer to this question.
Thanks
