Dual quads versus big hammer!!!...

Wouldn't it need "air flow", or vacuum to pull the gas into the secondaries? And if he had that, wouldn't the back flaps be open? If the Demons are like the TQ's, then the back flaps are part of the syphoning process to get the gas into the secondaries. Fact that the rear flaps won't open under WOT is a concern
The fact is the engine will only draw the amount of CFM in. How much CFM does jpars 410 pull in.
