The Gross-Pitaevski (GP) equation describing helium superfluids (Bose-Einstein condensate) is extended to non-Riemannian spacetime background where torsion is shown to induce the splitting in the potential energy of the flow. A cylindrically symmetric solution for Minkowski background with constant torsion is obtained, which shows that torsion induces a damping in the superfluid flow velocity. Since the exponential damping is a pure torsion effect, it is suggested that this effect could be used on a superfluid experiment to detect torsion.
