Hallo all,

The cannisters are made from cans were my wife put the coffee pads in and the prize was approximately 8 euro a piece.

The two headers I purchase by Krumscheid (K&S) 20 euro a piece. the rest of the materials is out of the scrap iron box.

And I'm worried about learning how to weld up my header from KS stainless steel fittings....

What a sweet job redcesar, I'm envious.

Hello Cesar,
Not only handcrafting but muffler desing looks impresive... inside there are more than the usually seem drilled plates named "waffle".
For the newbies, how all these tubes an chambers do work as a muffler?

OSCAR OCQUE

hi cesar, joe ven is my best friend, we are of venezuela, I do not speak English ,but your work is perfect....
in Spanish : me parece excelente el trabajo realizado, mi amigo joe ven tambien necesita un escape para su motor, cual es el diametro de la lamina de acero q usaste? .....

saludos oscar ocque , venezuela.


pd:excuses by my badly English

The principle of a cannister muffler is to break down the sound waves by forcing the sound through holes and pipes to break down the sond waves.
And that is what happens in the muffler, the sound must go through all the pipes and holes and bump into each other.

furthermore is it a rule that the restriction of the muffler is aprox. 70-60% off the exhaust port and you must reach that point in the last chamber of the the muffler.

The total volume of the muffler is aprox. 16x the volume of the engine and furthermore make the first chamber the biggest of the three for example 40%-30%-30%.

Make the header pipe as long as posible by let it end at the end of the muffler and let the outlet in front of the muffler, (front in-front out cannister)

Ruud, have you run the mufflers yet?

Alexzzz

Yes, he has. He has got some video's of the running engine as well, but I don't know where to find them

Grtz.

redcesar

Yes Pe, and i am verry satisfied.

I am turning a Engel 27x12 3 blade with 6300 rpm. with that combo the sound is reasonably.
But when i am turning the Mejzlic 30x10 2 blade the sound is much to loud, the prop tips going to fast and the tips are not narrow enough.
The Engel super silent 3 blade has verry narrow tips that make a lot less sound.

With the MVVS 116 and that prop the Pitts (14,5 kG) is inlimited vertical. That engine is extremely strong thats a fact.



Cesar (Ruud)

Zie mijn eerdere mailtje aan jou.

Hoi Pé,

Hier wat gegevens,

MVVS 116
Mezlic 30x10 5900 t/min
3W 30x10 5400 t/min
Menz 30x10 5700 t/min
Engel 27x12 3 blad super silense 6300 t/min

Ik heb de toerentallen iets naar boven afgerond omdat met de juiste brandstof en een ingelopen motor ik hier op uit zal komen.

Met de eerste 3 drie props veel te veel herrie van de prop.
Met de Engel 3 blad is dit in zijn geheel weg.

Maar wat een vermogen zit er in zo'n MVVS116 zeg onvoorstelbaar. met de Piits waar ik nu mee vlieg van 14,5 kG in een verticale vlucht stil laten vallen en dan daarna er met het grootste gemak er uit weg accelereren.

Gr. Ruud.

Thanks for the rpm update. I must have had an attack of brain obnoxia, because I still have the links to the videos :
