Ram tube air flow

[Frak]

Messing around today at work and decided to flow a 50mm orifice plate against an Imec AE111 ram tube.
The orifice plate flowed 335cfm @ 28inches of water
The Imec ramtube flowed 472cfm @ 28inches of water.

If I find a standard AE111 ramtube I'll give that a go on the flow bench as well.

Thought I would give a bit of an update on this seeing me and Jamie have been quite a lot of trial and error on the flow bench for my product development.

These where all tested at the same time at 28 inches of water. All the "SQ" ones where 3D printed prototypes that had been smoothed out before being flowed. None of the final versions have been flowed yet, it's quite likely that they will flow a tiny bit less due to the polished surface.

More about those ones


OEM BT: 320

OEM ST: 342

HRC: 445

IMEC: 483

Early SQ Blacktop: 484

Revised SQ Blacktop: 496

A few things surprised me about these results, such as how good IMEC are for such a simple design, how bad OEM is but most of all that silvertop outflowed black, to my eyes the silvertop factory trumpets look downright terrible with the transition into the throttle.

I really want to see a back to back run of OEM vs aftermaket on the dyno now.
