  • Velocity Stacks. Are they worth it?

    I understand the purpose of the velocity stacks but are they worth buying? I found 2 different ones or designs. But which one is going to give me more torque? The longer the stack, the better?

    The one in the 1st pic doesnt have the curve on the inside but it seems to be longer and the other one has the curve. I dont know which one to chose

    Either one, theoretically the one with the tapered Venturi would be better due to the taper. A decrease in volume causes an increase in velocity.

    Q=V/A where Q is the flow rate, V is velocity and A represents area. Although the ID of the openings are the same. The smoother you can make the transition the less frictional losses will incur due to turbulence created by the restriction, a laminar flow is more efficient.
