The largest, most efficient Supercharger Harrop has designed to date, the TVS2650 head unit features extensive manufacturing and design improvements over previous model generations. The FDFI (Front Drive/Front Inlet) format is retained for a shorter, less restrictive intake path and allows for three different directionally biased intake designs. The high twist, 4-lobe rotor design is 15% larger than the TVS2300 and features several improvements to maximize efficiency and performance at higher RPMs. Additionally, the Harrop 2650 supercharger incorporates a bypass system to reduce air handling losses when boost is not required, resulting in better fuel economy

R2650 VERSUS R2300:

  • 4% more efficient
  • 15% larger (2300cc vs. 2650 cc)
  • 18% less input power required
  • 25% more air flow at 18,000 RPM
  • 72%  isentropic efficiency vs. 68%
