Why an 8-Rib Drive Is Critical at High Boost
As supercharger pulley diameters decrease, boost pressure and belt load increase dramatically. Vortech's 8-rib conversion distributes load across a wider belt, improving traction, reducing belt wear, and maintaining consistent boost under hard acceleration - especially critical for track, drag, or high-power street builds.
