Ich hab mal einen Test gemacht der längst ausstendig war.  Jede Auspuffanlage einmal mit Originalen Steuerzeiten und einmal mit bearbeiteten Hauptauslass. Der Rest blieb gleich .   Dabe

Kleiner Auspufftest - L&S Otto, FalkR, PD Bullet, EGIG Boa       Es lief bei allen Läufen der selbe 38er Smartcarb (AQ-09) mit der selben Abstimmung.    

Halt ich hab es gefunden. Hab es noch nicht versucht, werde es aber selber bauen. Schaut sehr gut aus. Wenn es funktioniert baue ich ein paar mehr

@Brosi ...thanks for the link!

The  exhaust... I  guess it will set a  benchmark for the 2014  exhausts. Very silent and  powerful on a wide range and  fit under  the et3 original chassis  without any  cut.  The "sad" point is only that it can't be replicated  without be discovered.....

I think the idea has been around for some time (it has even been used by Piaggio), so I wouldn't call it "replicating" if something similar albeit for a differente type of tuning hits the market sooner or later.

Yes you are  right . in principle. But up to now  i still hadn't seen on the market a real expansion  with this solution. So before  this it was only an idea. let's see what happens in the next few months...

 

 

Ciao,

 

é necessario tagliare il telaio per il condotto d'aspirazione?

 

Saluti

Hannes

it's not a must, but you have to orient the hole in che  chassis by using a tube as big as the hole is and bending  it in the direction of the collector

 

ciao

Mauro

I also don't think another exhaust in this area could be called replicating just for the basic principle it employs. I would classify even more Vespa exhausts in the same way. The ET3 one is still quite far away... Polini "banana" and the like are more closely related. And just speaking from the outside, the closest match could be the PLC exhaust for the water cooled cylinders, which was also much more performance oriented than the previous examples. It's all just different styles of the same basic principle, which I find quite interesting, too!

 

Speaking from my own experiments, for a tourer that probably has rather too much than too little power and torque, this might be a really good choice  :-) But on the kart track I didn't really like this pipe style (i. e. not worth the tradeoff against a normal expansion chamber).

is das auspuffsystem eigentlich so ähnliche gedacht wie diese US supertrapp anlagen??

 

also vom prinzip her?

 

hast du mal in ne supertrapp reingeschaut? da wird der staudruck über die anzahl der eingelegten scheiben vor der endkappe abgestimmt. bin nicht sicher, ob das beim zweitakter so richtig funktionierne würde...

Jetzt wird schon tagelang über einen Auspuff diskutiert den amn nur von aussen sieht. Hat jetzt schon einer ne Ahnung was drinnen anders ist oder sind das einfach Spekulationen? Für mich mich sieht der von aussen wie ein normaler Kartauspuff angepasst auf Vespa aus, also nix besonders spektakuläres, ausser das mal wieder einer der erste ist. Oder wissen hier alle mehr?
