A reconditioned/rebuilt TVS 2350 Roots-type supercharger unit, commonly used in M50/M52/M54-based supercharger kits for BMW E36/E39/E46 and in V8-swapped chassis. Hyde Motor Works advertises this exact service ("Supercharger Rebuild"), explicitly listing the TVS2350 among the units they recondition — including rotor re-coating, porting, and bearing replacement — and backs the reconditioned unit with a 3-month warranty standalone or 12 months when paired with one of their kits.
