Als Add on een klein discussie met Bisimoto op Facebook over velocity stacks
.
Me'Just a thought here ... 2 velocity stacks on those 90 degree intake pipes ? (Talking about the Bisimoto honda insight)'
Mr. EzeriohaThink about it why would velocity stacks work in steady state when the vehicle is at rest, but hurt flow when travelling (racing) in a fluid?
Me I would think the velocity stack does the accellerating of air by itself (shape). But under pressure (ram air) it produces turbulence ?But i'm having a feeling you're talking about air in a different way then i can understand.Let me know if i'm in the right direction or not ,love to learn more about this...
Mr. EzeriohaYes, you are. Think of the tangents formed by the airstream when it hits the velocity stack "lips" when travelling in the path of high velocity fluid.
Me Ahh ok i see.If we are using an enclosed velocity stack ( in front of the throttle body as a part of the intake) could we solve this kind of problem if we designed the velocity stack right ?A half radius that starts from the sidewalls to the throttle body's inner diameter for example? Or is there still turbulence formed?
Mr. EzeriohaHow about an enclosure/atmosphere that is pressurized, and contains individual inlet stacks, and that enclosure is fed by feed(s) that travel in a high velocity stream, with an apature that doesn not have a radius lip...or one of very small "lip area"
MeAka Tubocharged itb's....You're right i didn't even think about it in that way.Thx for the lesson so far !
Mr. EzeriohaYes, Nick, and can work well with a pressurized intake via ram air.
