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.

Will buy again!!!
Color: Blue+Purple
I bought a set of these toys for my 30 lb black labs (mixed breed). They are normally very aggressive chewers, and as a result, these dogs are difficult to find toys for. They destroy pretty much everything except for those very strong rubber toys which are not as much fun for them to play with. So far, these toys have lasted us 2 days and counting which is quite an accomplishment considering their soft toys typically last about 10 min. or so before they start eating the stuffing and pull the squeakers out. Between the plastic noises from the tenticles and the squeakers my dogs have just been having the time of their lives. We have to confiscate them at bedtime so we can sleep! Even though I'm positive these toys will not hold up for much longer because of their chewing habits, it was worth the money to splurge on something fun for them to get so excited to play with. I intend to replace them occasionally as long as we continue getting at least a couple days of use out of them. If your dogs are less aggressive chewers then you should definitely give this toy a try!

Great toy
Color: Orange+Green
My dogs loved getting these for Christmas! They each have one so they don’t fight over the one toy. Value for the money is good. They constantly play with them and the portability is great too. My one dog, Poppy, drags the orange one outside all of the time

Fun toy for the family dog but the puppy can pull the crinkle paper out
Color: Orange+Green
I would have given this five stars because my 5-year-old Australian shepherd border collie loves it shakes it tugs with it. It has held up great until we got a puppy and then the puppy pulls out the crinkly paper which looks just like a clear plastic wrapper so that's not good this is our second time ordering these. The first time was for my current dog and the second time when we got the puppy so he had something to play with too.

Cute, Affordable, Dogs Love
Color: Purple+Green
These are super cute. Both of our girls love them. Got them in January and we still have both of them as faves in May. That’s pretty impressive with the amount of toys they rip through. They 100% can easily be destroyed. Our dogs have preferred keeping them. They just enjoy these toys.

So-so...
Color: Blue+Orange
50lb German Shep mix chewed through the head within a couple days and pulled the squeeker out. Not horrible, but not as durable as they seem to imply.
