Development
When the new billet velocity stacks where being designed, they where made from the beginning to be the best there is. These shown here are the result of research, prototype works, testing and then finally CNC machining of the final product.

The shape of the bellmouth, inlet transition and taper where all optimized to allow for the highest net airspeed possible. During development multiple prototypes where made and put on the flow bench, even the rough test version was able to outflow HRC, IMEC and by a massive 55% the original rubber OEM stacks.
