EMPI Pro-Sync Carburetor Synchronizer - Dual Carb Tuning Tool - 43-5718-0

EMPI Universal Pro-Sync Carburetor Synchronizer (Includes 1 Boot Adapter)

Achieve peak performance and a rock-solid idle with the EMPI Pro-Sync. Essential for anyone running a dual-carburetor setup, this precision instrument allows you to accurately measure air intake across all barrels to ensure your engine is perfectly balanced.

Unlike older "bubble-style" gauges, the Pro-Sync is designed to allow air to pass through without restriction, providing a highly accurate reading without stalling the engine or affecting the vacuum signal. The large, easy-to-read scale (graduated from 1-30 kg/h) allows for the fine-tuning required for crisp throttle response and optimal fuel economy.

Product Specifications & Features

• Measurement Range: 1-30 kg/h numbered scale for high-resolution tuning.

• Non-Restrictive Design: Will not choke the engine during the sync process.

• Versatility: Includes one rubber boot adapter to fit various intake diameters.

• Compatibility: Works with both down-draft and side-draft carburetor configurations.

• Build Quality: Durable housing designed for professional shop use.

Vehicle & Engine Fitment

This is a universal tool designed for air-cooled and water-cooled engines running multiple carburetors, including:

• VW Type 1, 2, & 3: Perfect for Dual IDF, HPMX, Dellorto DRLA, or dual Solex/Kadrons.

• Porsche 356 & 912: Essential for Zeniths or Solex 40 PII setups.

• Performance Upgrades: A "must-have" for Weber IDA or IDF equipped street and strip cars.

• British & European Classics: Fits a wide range of side-draft (SU/Weber DCOE) applications using the included adapter.

Tech Note: For the most accurate tune, synchronize your carburetors at both idle and at roughly 2,500 RPM (holding the linkage steady) to ensure your linkage geometry is pulling evenly across the entire powerband.
