Tuned pipe experiment

And now wit larger exit

Did you get any tachometer readings before and after modification? Would be nice to know if it increased performance over stock.


Avez-vous eu des lectures de tachometer avant et après la modification ?Serait agréable de savoir si elle a augmenté la performance par rapport aux actions

As it is visible on the photo I have several pieces like this and several other different exaust collector y have place presure pickup tube To presurise fuel tank wit When i go Test I will make a comparative video of the result
The tube is riveted in place

The tube help holding in one direction so it Not rotate is also hi heat resistent gasket maker use To seal the part To its cylinder its seal tight no leak y use the no7 Dual Bypass, Single Boost Port Per Side
Factory Ground for Throttle Rings
Early 1990's Manufacture
Non Sub-Induction
New Original Cox Items its made for it and y found that the cox collector nead that no7 ground  cylinder    
To function properly

Y tink the part was use To redirections of exaust fume out side engines compartiment it was use on no3 ground cylinder wit spi tink it was To limit the speed reducing performance lot no3 cylinder its one hi performance cylinder

Videos are nice, just not very telling of what is going on. It would be good to see the performance differences based on tachometer readings. The human ear is not very calibrated.

Even if the tach is off at least it should show the before and after difference. Some use audio tachometers downloaded onto their smartphones. I am leery of them, folks do claim they work though and at least it’s something to go off of.

Les vidéos sont agréables, mais pas très révélateur de ce qui se passe.Il serait bon de voir les différences de performance basées sur les lectures de tachometer.L’oreille humaine n’est pas très calibrée. Même si le tach est éteint au moins il devrait montrer la différence avant et après.Certains utilisent des tachomètres audio téléchargés sur leurs smartphones. Je me moque d’eux, les gens prétendent qu’ils travaillent si et au moins c’est quelque chose de se passer de.

Don't worry I own a tachometer m'y is a Digital Tachometer
Item No.HAN156 from hangar 9 tink somtime the Reding is Not correct No enough light y tink it can read difrent prop 234 blade  tink of using in the vidéo y wil made Not now du To very low température My hands hurt verycold:

Y tink y have To try one of chose ap if they work i wil use audio tachometers on m'y rc cars as Most of m'y extrême performance engine Have now become car engines y have no other way To tach them now Most of the time if y Find engine wit over 19 k y use the engine cylinder piston tank wit its back plate on cars crank and build insane jerobee modified engines u Find no jerobee 350_4 wit no 7 cylinder or no4 y have se one jerobee wit the texaco tank for bether fuel draw at lower rpm wit lower power lost of rpm To y made one extrême gtp setup wit heat sink modified fuel tank no 7 cylinder y want To change the casing for one anodised new color y want To dy color To m'y own parts build performance engine wit A color easy to distinguish from other engine that already exists With the new restriction of the faa tink cox international and ex models engines Really should offer parts option for car engine conversions like the egr valve clutch flyweel new model of clutch y have made lots of experiment wit them cars engine Not so difrent the gtp in fast is just like the sure start engine just difrent cylinder the kyosho f1 use the same size flyweel as the plane stuf become hard for Mr. Madam everyone cars is one very big parts of the hobby Not wit cox cars its like just collections items just look toyan wy is so popular its simple To instal them in truck simple as that just give me the tool y build one crazy stuf wit cox engine To promote cox engine in the world as the kids that Not nowing it existe

Looking forward to the results, especially the exhaust collector.

Wit bit of mony y can start new production of rc cars powered wit cox engine y have new prototype on the work table and it look Good y save mony for late miling cuting table To cut carbon fiber y tink of askin 3 part To cut the carbon frame parts as its nasty stuf y don't want to die and for the engine parts If no one wanna make a new car part, I will its just mony that hold me back right now if cox or ex models want To build ther own or Maybe even m'y parts model its ok y just want parts so y can build new stuf wit old cars its cool but y like To run them and y run them a lots more than y do plane now
