Thread: Flow Stacks and Turbines

TeKKiE, yup it wont do any good after the turbo, but as inlet it should be a noticeable difference.



Well I don't know if that's exactly the case, it could easily be. If you run out of air to suck in, are you making vacuum? Or I guess you could run out of air molecules...

Tekkie, you weren't trying to say a velocity stack inside a plenum on a turbo car is counterproductive were you?

Ben, no. In a plenum is a no brainer. I'm talking about sticking a flowstack on the compressor outlet, horn facing away from the wheel, then having intercooler piping on it. That's what I thought was being done in the above test. Now after seeing more pictures it makes sense what they did.

I just mean, for instance...if you stick a fan too close to a wall, not enough to completely block the back side of the fan, the closer you get, the less out put you get. Seems to me that's because there's less air to go through the fan, or if you think about it...less space in which to replace the air you're sucking from there. Obviously with a fan or turbine, you have a low and high pressure side...in order to create high pressure on one side, you have to create low pressure on the other. So, if there is a low pressure area behind the fan, more air has to come into that area to get the low pressure back to even. Now, obviously that isn't what's going to happen, but that's what's trying to happen. So, if you have those eight turbines creating one massive low pressure area, I would think, you'd suffer in the efficiancy of the turbine to create high pressure on the other side. So, it makes sense to have these tubes so that each fan, in effect, has it's own low pressure area with space in between them. But maybe I'm just thinking way too much into it...but it makes sense to me.

Sounds about right 84300Z. I wonder if it would be the same in a big open space though, like no walls near by to restrict fresh flow.
