The Thunderchine augmentors would need to be smaller. If possible print the plans at 74.6%

If not an option then try to build near the standard augmentor formula seen below. Bashing and weld what you have available as Jutte recommended.

How about this. Looks like they could be a bit longer?

by using the standard augmenter formula i get the following values..

delta= 2*5= 10cm

D=2.6*5= 13cm

L=10*5= 50cm

R= 0.25*13= 3.25cm

what do you think about this..

Ganuganu the math looks good, metiz, i agree that looks a little short for my eye. It is important to have a smooth interior seam between the flare and the augmentor body. Looks like the flare could be slightly wider, but what you have there is a good place to start.

The engine geometry is limiting what I can do with these augmenters unless I make then ridiculously hard to build. Ill lengthen the augmenters and add some fat to the flares. Asume they're hammered into a nice belmouth instead of a hard cone, don't want to make those things in sketchup

here is the drawing of the calculated dimensions..is it k to use it in the intake side..

Look at your engine - you'll never be able to fit those

wow, those dimensions are on the large size, best to wait and see what metiz formulates.

dual augmenters don't realy work. I'm trying to fix up a single augmenter for both intakes now. Kinda hard, stand by.

'Knew I had them. 'Been looking a long long time for 'em. Found 'em: I will post a link in the plans section.

Dankjewel Fedde.

Thank you, reading english pulsejet reports is really good for maintaining the knowledge of the english language
