Billet Aluminum EFI 97

Autotrend EFI has captured the style and look of the vintage Stromberg 97 and 48 carburetors with our new Billet Aluminum EFI 97

 EFI 97 

Features

  • CNC Billet Aluminum Construction

The EFI 97 has a unique 5 piece design. All components fit together perfectly due to precision CAD/CAM design. 

  • Single Oval Butterfly Design

The EFI 97 incorporates a single oval butterfly allowing 65% more air flow than a conventional Stromberg 97 carburetor. **  See flow Data

  • Stainless Steel Throttle Shaft With Roller Bearings and internal clock spring

Precision smooth throttle shaft movement and consistent throttle return are a must whether your running a single 97 or multiple 97’s. Each unit has it’s own adjustable internal clock spring insuring positive throttle return and eliminating the need for external return spring. Each unit incorporates positive stop idle set adjustment and wide open throttle stop. Stainless steel shafts ride on precision roller bearings for extremely smooth throttle action and consistent throttle return.

  • EFI 97 Finish

 Standard is a brushed aluminum finish.  Custom finishes available.

  • Complete Systems

Units are sold as a complete system including Engine Management System, Custom Wire Harness.

  • Flow Data

The EFI 97 was flow tested on a SuperFlow SF-600 flow bench.  We did a comparative flow test between an original Stromberg 97 and our unit flowing them at today’s industry standard of 28 inches of water… The results were impressive.
