I do think augmenters add thrust, but have no technique to quantify it. What are your observations?

There is not a good method to find decibles from video, so not sure how loud it is.

the sound was too high, and it pushed the cycle hard, and the thrust was felt more than 6to 7 meters effectively.

:D
Let us know how it pushes the bike, but make safety the first priority.

Still getting ready with the batteries for my blower, because i cannot ride my cycle near my house. So i decided to ride it in highways or empty grounds. I will post the video as soon as i ride it. :)

One question here, i planned to fit a 5kg gas tank but i have a doubt whether it will be enough to propel my engine.
Update:
I have covered all the danger areas with double layer of sheet.
I will post the video of me riding the bicycle :D :D within three days.

ATLAST SUCCEEDED MY LONG TERM GOAL
Hello everyone this is the first time i ran my bicycle with the engine i thought to run the bicycle for two rounds but unfortunately the end plate got damaged and flamed out so i was able to run the bicycle for 12 seconds. And really augmenter was very useful for my engine it gave some good amount of power. This was my long term goal atlast i achieved it successfully without any damage to me.

video took by my sister and initially my mom was holding the engine, thanks to them. And also thanks to pulsejet forum members. Next i planned to change the combustion chamber with stainless steel. At the end you could see the picture of the damaged end plate. Forgot to tell the sound was enormous.

Good to hear you escaped without harm.

I wouldn't have predicted it opening the end plate like that, interesting damage. Unfortunately pressure will create a load on a corner, typically they hold together, sometimes they don't. The tail pipe typically will crush, only a few have blown a CC end cap.

Joe iam sure that my engine was powerful because it pulls me so hard i was trying to control it. Last time i forgot to tell that after augmentation engine is getting red hot sooner than before i dont know why?

I would propose that is because the engine is producing higher temperatures and pressures for more of the cycle. More of the CC is swept clean of exhaust allowing a better fill ratio of the CC. The pressure is released more slowly through the augmentors, and directs the intake exhaust in a specific direction.
