The Helix is a planetary gearbox for the factory high pressure fuel pump on the N54 and early N55. By spinning the pump faster it adds delivery strokes and raises HPFP capacity, curing rail pressure drop on tuned cars without the complexity of port injection. Spool rates the standard Helix at up to 600 whp on full E85 and 750+ whp on E60 blends.

Features

  • Planetary gear set (ring, planet and sun gears) overdrives the factory HPFP
  • Helix: up to 600 whp on full E85, 750+ whp on E60
  • Uses your factory Continental HPFP
  • Spool's testing found no extra wear or failure risk from overdriving the pump
  • Optional Helix 10 micron filter unit (highly recommended)

Good to know

  • Tune changes are required. Spool works with the major tuners and supplies the calibration changes on request.
  • The higher capacity Helix Xtreme is not part of this listing. Spool rates it at up to 750 whp on full E85 and 850+ whp on E60 or gasoline, and lists it as still in final durability testing.
  • Spool's testing looked at the known Continental HPFP failure points (inlet metering valve solenoid faults, and limp-home bypass valve seals that can degrade with long term E85 use) and found the Helix does not make them worse. High mileage pumps they inspected showed minimal wear on the swash plate, springs and pistons, and oil analysis showed very little metal.
  • Option guide: pick your engine (N54 or N55), then choose whether to add the Helix 10 micron filter unit.
