Nitro effect on temperature?
I posted this question in the fuel section and got one reply, but was hoping more would weigh in, so I'll post it here as well.
I was wondering what kind of differance in temperature is noticed when switching from 0% nitro fuel to 15% fuel?
I have an Enya 155 with a rebuilt muffler using pop rivets to hold it together, and some JB weld to seal all of the parts. I am just wondering whether 0% or 15% will give a enough of a differance in temperature to use without melting the weld.
I have heard over and over again that 0% nitro fuel works great in the Enya 4-strokes, so I want to try that first.

Hither nitro = hotter temperature and faster fuel tank emptying. The total effect i dependant on the airflow past the engine... how you tune it... how large a prop you stick on...
If that enya has run all its life on 0% nitro... I bet the head shim has been pulled. (or never inserted.) Going above 10% nitro on that could severely damage the engine. With the head shim... it would not run for beans without at least 10% nitro.

Hi!
I can assure you that your Enya will much better on 5-15% nitro than on 0%.
As for temperatures ...Using nitro does not necessarily mean higher temperatures
what it means is that the power=heat is available if you want it....not that the heat is higher all the time you use nitro...just that more power=heat is available if you want it.
Heat could be even higher using no nitro at all if you set the highspeed needle for max rpm using 0% nitro! or run the engine a little lean...which is more easy to do when you run no nitro due to the narrower needle setting range.
On the other hand set the needle a little rich and use let's say 10% nitro..you will notice more rpm than when you used 0% nitro and a more broader needle setting range. You would also notice that the engine would run smoother.
Regards!

RE: Nitro effect on temperature?
jaka is right about the "available temps", but here's what you are looking for: your engine will be O.K. with JB Weld, up to 15% nitro- been using it to make mufflers/ect. for years. I even tried the high temp JB Weld, but found that the regular is just fine. Right now I've got a 4 stroke, and a 2 stroke with JB holding them together (muffler mount/exaust port on the 2 stroke .40 S.T., backplate/crank case on the Magnum .52 4 stroke). No problems
