I put on some super 40s. I listened to it with the resonators on and I didnt notice a difference so I deleted the resonators. Sounds pretty good. Big question. Does this give you more horsepower deleting and adding new mufflers?
Maybe in a way it is (exit velocity and pulse vacuum) but really rocket science is not really that difficult either.[/QUOTE said:Good post by the way. Anyway, the V1 Buzz Bomb used a Pulse Jet motor that depended on the principles we are discussing. https://www.google.com/search?q=why+does+the+exhaust+of+X1+rocket+show+pulses&biw=1680&bih=902&source=lnms&tbm=isch&sa=X&ved=0CAYQ_AUoAWoVChMIzuHg2-TsxwIVhY0NCh1X7wK1#tbm=isch&q=why+does+the+exhaust+of+V1+rocket+show+pulses&imgrc=IInXtdx2Abor8M%3A
I do believe a slightly bigger diameter exhaust can add more power if tuned...
