EMPI Pro-Sync Deluxe Carburetor Synchronizer - 2 Adapter Kit - 43-5712-0

Universal Pro-Sync Carburetor Synchronizer (Includes 2 Boot Adapters)

Eliminate the guesswork and synchronization headaches with the EMPI Pro-Sync Deluxe Kit. This precision-engineered tool is essential for anyone running dual-carburetor setups on air-cooled Volkswagens, Porsches, or any multi-carb vintage engine. By measuring actual airflow volume, it allows you to perfectly balance your carburetors for a smooth idle, crisp throttle response, and maximum power.

The Pro-Sync features a highly sensitive, non-restrictive design that allows the engine to breathe naturally while you take your measurements. This "Deluxe" kit includes two different rubber boot adapters, providing maximum versatility for various carburetor throat sizes and intake configurations.

Product Specifications & Features

• Dual Adapter Kit: Includes two distinct boot sizes for a universal fit across a wide range of applications.

• Non-Restrictive Flow: Unlike older bubble-style gauges, the Pro-Sync won't choke the engine or cause stalling during use.

• High-Precision Scale: Easy-to-read 1-30 kg/h numbered scale for ultra-fine tuning.

• Versatile Application: Designed for both down-draft and side-draft carburetors.

• Professional Grade: Robust construction designed to withstand daily use in a busy restoration shop.

Vehicle & Engine Fitment

This tool is a staple for tuning nearly any performance air-cooled engine, including:

• Volkswagen Type 1, 2, & 3: The ultimate tool for balancing Dual HPMX, IDF, Dellorto DRLA, or Kadrons.

• Porsche 356 & 912: Vital for synchronizing Zenith or Solex 40 PII units.

• Custom & Performance Builds: Essential for Weber IDA (48/51mm) setups and large-bore stroker engines.

• Broad Compatibility: The two included adapters allow for use on many European side-draft setups, such as Weber DCOE and SU carburetors.

Tech Note: If you are running a balance tube between your manifolds, be sure to temporarily plug it while using the Pro-Sync to get an isolated, accurate reading from each individual carburetor barrel.
