Do you say 8cm length and 4cm diameter of augmenter, sorry dont mistake me if iam wrong.

8cm tailpipe diameter should give approximately 4cm on the augmentor diameters. The augmentor length is probably near 32cm. Not sure how reducing the intake diameters will affect it, but should be close enough to see considerable thrust improvement. Also let us know if the sound increases from adding the augmentors.

ok then i will make the augmenters fix it,test it and update it here. Waiting for the gas tank.

Have you designed that car/kart yet? I like the idea of those aero dynamic down hill gravity powered cars with a pulsejet or two shoe horned on.

We want more video :D
Still in the process of making augmenters, after testing with augs i will update here :D

an important thing shall i place the augmenter at a distance of 6cm from the intake pipe or more than 6cm.

Should be near 3.5cm to 4cm, make it adjustable if possible. The goal is to capture the pressure/flow that is blown out the intake, but allow enough space that it doesn't degrade the intake in flow.

Today only the gas strike was over, so i will get gas cylinders by next week. Because of these strikes my projects were stagnated. :evil:

Make sure you put up some heat shielding for your tires and legs or the meat and rubbers will melt off both of 'em

can anyone help me here i planned to attach an augmenter for my engine attached to bicycle. Diameter is 34mm and length is 200mm. This is for intake side and intake dia is 23mm. Throat dia is 52mm.

Fixed the augmenter to my engine and result was this, take a look at the video. i dont know whether its powerful or not because i didnt hold the bicycle, but my mom told that she wasnt able to hold the cycle because it was pushing so hard. But according to me the sound(noise) was too much than before.

Good work on it, I wasn't sure how to calculate a augmentor with that intake/tail diameter. Looks like you estimated it close. The augmentors could have 37cm more length added to the back if you need a little more thrust. You can see the flame pulsing out the back of the augmentors.

Be careful, those intakes are just below where your body would be sitting, and if a pulse stopped the flames from the intake could burn thighs, calves, and feet. Make sure you can shut off the fuel quickly. Always do a technical inspection and check for lose fuel connections or leaks or any multitude of things that could fail.
If you must ride it, apply water to your hair and clothing. As metiz advised shielding would help considerably.

Thank you joe, do you think my engine puts out more thrust with that augmenter. Can that sound be 100decibels?
