Dual quads versus big hammer!!!...

I showed this picture Street Demon discharge nozzle..

Notice those two big openings on either side as you can look down through them right into the discharge holes? seems to me this is where the fuel is getting pumped up words and out?
Here's a picture from Summit of a demon discharge nozzle and it's capped off and only can go the One direction straight down in.. my thought is to order a couple of these..??
