so we all know that high speed air creates a low pressure region (bernoulli effect) right? this creates lift in wings, and likewise creates pull in other similar situations.
i just thought of something wierd that i thught id mention - so with exhaust systems, supposedly a loss of backpressure is bad for torque… and at very high rpms, the free flowing exhasut is good… so, imagine (dont laugh) if exhaust pipes faced straight up…(or down, or sideways…). what would theoretically happen, if the pipes were good for backpressure, is that at lower speeds, pressure would be normal, and at high speed, a vacuum effect would occur, creating a low pressure zone outside the exhaust pipes, which would draw gases out at a faster rate… sort of like a ‘automatic variable backpressure adjustment’
i dont know why i just typed that, since in retrospect it seems ridiculous, but whatever… I = :tard
