Introducing back-to-back SEMA award winning Turnkey EFI by Speedmaster.

Speedmaster™ EFI Systems have won 2010, 2011 & 2013 Sema Show Global Media Award.

The Speedmaster™ development team have been pushing the boundaries for years with a main objective "to improve the end user experience"; one of the many industry acknowledgements are the 5 in a row SEMA Show Global Media Awards for their research and development of their Pistons, Turnkey EFI system and Manifolds.

The TurnKey EFI Individual throttle body system has all the flash of classic Weber induction with all the function, performance and versatility of modern fuel injection.
This highly advanced system allows a broad camshaft selection and delivers performance that is capable of supporting up to 1000 hp.
Fuel and air is delivered through precision cast aluminum 50mm IDA style throttle bodies that allow for superior idle characteristics and astounding throttle response while improving emissions and economy through tight air/fuel ratio control.

  • The Speedmaster manifold has a lower vacuum plenum for the MAP sensor and any vacuum operated accessories
  • Speedmaster linkage set incorporates the throttle stops, idle controls, lever arms and joiner/balancer all in one. It also features a single screw adjustment for calibrating front to rear throttle shafts.
  • The bell crank has a fully indexable eccentric cable pulley that enables good slow speed drivability and still attain full throttle geometry.
Speedmaster throttle bodies have the following features:
  • CNC machined, Heat treated 6061 Cast aluminum.
  • Butterflies are measured for each bore & precision machined to a 0.0005" tolerance.
  • Butterflies are secured to centreless ground brass shafts with split screws to ensure reliability and service ability.
  • All are fitted with bearings rather than bushings to eliminate axial shaft movement.
  • Housing to shaft lip seals behind bearings for extra sealing under high vacuum.
  • Idle by pass air bleed screws for super smooth idle and to aid emissions tuning.
  • O’ring seals on lower mounting faces.
