DaVinci Performance Modified Alcohol and Gas Tunnel Ram Carburetor Matched Setup

 

This modification is where technology and skill come together to outperform any other available carburetor. This carb is designed for good idling, razor sharp throttle response and increased horsepower. Extensive modifications are made by the knowledgeable DaVinci crew.  These mods are then applied to make gains ranging from 5-50 horsepower over all other modifications. All carb pairs are flow matched and jetted to the exact specifications for your motor. This carb can be used for drag or circle track application with big block or small block engines. It is quality tested on a race engine with float level and idle preset for out of the box operation. All parts are coated to a high luster to add reliability.

  • Blueprinting/Machining

          All circuits modified for correct size and

              all passages cleared of casting

              obstructions

          Metering plate, main body, and baseplate

              machined and squared for flatness

          All bosses blueprinted (threads, throttle

              shaft bores, and booster pads)

          Airflow increased and balanced by blending

              and contouring venturis and profiling

              shafts

  • Calibration

          Airbleeds sized to specification. Adjustable

              airbleeds installed when allowed by

              rules

          Fuel emulsion system tested and equalized.

          All emulsion circuits have been sized and de-

              burred for maximum atomization and flow

          Squirter system modified and calibrated to

              eliminate bogs, sags, and hesitations

          Power valve (enrichment) and main circuits
              (jets) are calibrated

          Custom squirter emulsion system added

  • Booster Alignment/Installation

          Booster centered within main venturi on

              a close tolerance jig

          Booster secured to reduce hazardous and

              power robbing vibration

  • Precision Assembly

          Welded linkage, button-head butterfly

              screws

          Premium non-stick gaskets used throughout

          Blueprinted hi-flow needle and seat installed

              along with squirters

          Extra tall vent tubes installed

  • Tunnel Ram flow matched and jetted

  • Flow testing and Quality Control

          Tested on a Superflow bench for correct

              and even flow
