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.

Great toy
Color: Black/Orange
This brand really makes durable toys. They outlast every other toy my dogs have. One dog loves to get the squeaker out of any toy, but he doesn’t rip this one apart. Obviously it won’t last forever, but no toy does! Some other brands of toys only make it a day or two, while these last months to years.

Great toy for two big German Shepherds
Color: Brown
We only buy Tuffy dog toys now because we have one German Shepherd, and we often watch our daughter's GSD too, and the two dogs tear anything else apart in minutes. Tuffy toys are BY FAR superior to any other dog toy we have tried. That being said, some Tuffy toys seem to last longer than others with the two dogs, and this one has been pretty good! We've had it for a few weeks now, and it's just now starting to show some white (stuffing) where their teeth have pierced the top of the toy. That's pretty good, considering they play tug of war with it and can tear into toys pretty hard. If it were just our one dog, I think it would last a lot longer because it's the tug of war between the two of them that does them in faster. Even so, when they do manage to tear the fabric in vulnerable places, I just pull the stuffing out from that area, and they continue to play with it, sometimes for months! This one is better than some other Tuffy toys too because it has lots of areas where there is already more fabric and reinforced seams than stuffing, like all the legs on the side, the tail, and even the pincers. So far, they haven't been able to tear into those at all. Just a bit on the top of the head, and so far, no stuffing coming out yet. This one is a big win for us! When they finally do do it in, I will turn around and buy another Scorch the Scorpion right away!

Tuffy Desert Phrog vs Lola
Color: Green Leaping Phrog, Color: Green Leaping Phrog
Just a little background about my dog. Lola is a 5 year old corgi-terrier mix with jaws of steal. Lesser stuffed toys have met death in under 5 minutes. Tennis balls last less than a day. Rope toys that do not have frayed ends might possibly last a week (frayed ends never stand a chance). The only toys that she has not managed to destroy are her Kong, a Kong bone, and a racquet ball. I figured I would document the life span of Phrog (Tuffy Scale: 9) before making my final judgement on it’s durability. Day 1 - Phrog Arrives! Lola was very excited about the arrival of Phrog and immediately went into destruction mode. Phrog did sustain a little damage before we were able to bribe her to drop Phrog and get her understand that he was more fun to play fetch with than to mutilate. The white you see in the picture is not stuffing, but the second layer of defense for the toy. The fact that my living room is not full of stuffing and I didn’t have to pry a squeaker out of my dog’s mouth, I’d say Phrog wins the Day 1 challenge. Day 9 - Phrog has sustained a little more damage, but not anything life threatening. His side wound is a little bit larger and one of his eyes is half ripped off. For safety reasons, I am going to finish removing the damaged eye and some loose thread from various places. Other than that, Phrog is still holding up and holds top toy spot. I have also found him very useful for dealing with anxiety; the squeaker can often distract her from her stressors and Phrog takes the abuse of her frustrations. Day 16 - Phrog is starting to show signs of mortal wounds. Lola has made it through the thicker layer around his arm and I can see the stuffing. It is only a matter of time before gets all the way through. Day 60 - Phrog still lives!!! I have done some surgery on Phrog to reinforce the fabric around his arms, but Franken-Phrog is still the favorite of all of the toys. She will even get brave enough to rescue Phrog from the evil vacuum when he is kidnapped and tortured. I am thinking about purchasing Phrog II for the inevitable day when Phrog goes off to the pet toyland in the sky, but for now, there is only one Phrog for Lola.
