Latest Rage Deluxe Carburetor Airflow Meter Pro-Sync — Universal 1-30 kg/h Non-Restrictive Gauge

The Latest Rage Deluxe Carburetor Airflow Meter (Pro-Sync) is a visual precision tool that balances dual and multiple carburetors by measuring airflow from 1–30 kg/h without restricting intake.

Fine-tuning multiple carburetors is critical for smooth idle, consistent throttle response, and equalized performance across cylinders. The Latest Rage Pro-Sync synchronizer provides a simple, mechanical way to visually compare airflow between side-draft and down-draft carburetors used on classic VWs, dune buggies, motorcycle trikes, and other multi-carb setups. It’s built as a universal, non-restrictive gauge with a clear numbered scale so you can dial in balance quickly and accurately.

How does the Pro-Sync balance multiple carburetors?

The Pro-Sync measures the relative airflow through each carburetor throat and presents that reading on an easy-to-read 1–30 kg/h scale. By comparing readings for each carb and adjusting throttle linkages or vacuum ports, you achieve consistent airflow across all carburetors.

• Visual comparison: side-by-side airflow readings for each carb throat.
• Numeric scale 1–30 kg/h for precise adjustments.
• Works with both side-draft and down-draft carbs — universal fit.

Will using this tool affect engine airflow or performance while tuning?

No — the Pro-Sync is designed to avoid restricting intake air during measurement. Its airflow path and sensing method give accurate readings without creating vacuum artifacts that could skew synchronization.

• Non-restrictive design prevents false readings from induced backpressure.
• Quick connect technique means minimal disruption to running engine.
• Safe for use on running engines when following proper tuning procedures.

Which vehicles and carburetor types is this synchronizer compatible with?

The Latest Rage Pro-Sync is intended as a universal instrument for most multi-carb setups. It suits classic Volkswagen models (Beetle, Karmann Ghia, Bus), dune buggies, small displacement motorcycles with multiple carburetors, and many aftermarket side- and down-draft carburetor systems.

• Ideal for dual-carb VW engines and similar configurations.
• Effective on motorcycle trikes and other twin-carb small engines.
• Compatible with a wide range of aftermarket and OEM carburetors.

How precise is the numbered scale and what maintenance does the tool need?

The Pro-Sync’s 1–30 kg/h scale delivers repeatable, readable values that help you make small, meaningful adjustments. Maintenance is minimal: keep the sensor passages clean and store the gauge away from contaminants to preserve accuracy.

• Clear numeric markings for consistent tuning measurements.
• Simple cleaning of ports keeps readings reliable.
• Durable construction for repeated shop or field use.

Who is this for: The Latest Rage Deluxe Carburetor Airflow Meter is aimed at mechanics, classic car restorers, backyard tuners, and performance enthusiasts who work with multi-carb engines. If you tune dual or multiple carburetor systems on VWs, dune buggies, motorcycle trikes, or other small engines and want a fast, accurate visual method to equalize airflow without invasive fixtures, the Pro-Sync is a practical addition to your toolkit. It simplifies synchronization tasks so you spend less time guessing and more time driving.
