i heard about these either on this board or another one...don't they have intakes?
either way...the whole point of the post on the other board is that when you're installing something for exhaust/intake, the idea is to make the most direct path for your air flow...which...this thing sounds a little bogus.
"When the incoming exhaust air stream enters the Aeroturbine it is rapidly expanded due to the properties of heat transfer, and then split via an airfoil cone with an orifice similar to a conical jet engine."
- hot air expands...air comming from the engine into the exhaust would be hot...but they're talking about heat transfer, which would involve the hot going to cold...which means the air would become more dense as it cooled down (flowing through the exhaust)
- the other thing they're talking about is speeding up the velocity of the air as it exits the exhaust...which can make sense (i'm chalking the above point up as being a typo on their part, or just a 2 second explanation on rather large theory...)....the one thing you'd want to make sure of is that if their intake end of the exhaust is the same size as the exhaust end - changing the size (IE; large intake of exhaust from engine, smaller exhaust tip) would speed up the velocity of the air just through the physics of fluids...but it wouldn't necessarily mean that you'd be getting better airflow
they need a, "SHOW US THE DYNO" smiley....
