When you're building or fine-tuning a high-performance engine, every part matters. A vacuum pump is one of those power-adders that can make a real difference. By pulling excess air, oil vapor, and pressure out of the crankcase, it improves ring seal and reduces drag, freeing up horsepower that would've been lost to windage. Plus, it helps keep your oil cleaner and your engine breathing better. If you're serious about performance, adding a vacuum pump to the setup is a smart move—just what you need to keep everything running tight and fast.

Can be used on driver or passenger side.

Testimonial

We use a vacuum pump kit for our in-house dyno testing. The vacuum pump kit in the picture shown above has been used to test over 1,200 engines over four years and is still going strong.

What makes GZ Pumps Different?

While most vacuum pumps may appear to work the same, the fact is that there are major differences on the inside, where it counts. The recently redesigned Pro Racing Vacuum Pump is a purpose-built pump specifically designed for the hot, wet, and oily environment found in race car crankcase vapors.

An all-new die-casting, only available from GZ Motorsports, forms the core of the new pump with much closer tolerances than previous models, enhancing its airflow potential. Closer tolerances in the new die-casting allow the Pro Pump to generate 26% more airflow than similar-sized competitors' pumps! Updates also include improved and beefed-up port locations, totally rebuild-able bearing sections, and long-life wipers.

As with all GZ Vacuum Pumps, Rulon Wipers are still used exclusively, as Rulon is the best material GZ Motorsports has found to use for tough, hot, and oily applications. In fact, this pump can suck in and spit out anything but metal without sticking! In fact, recent durability testing conducted with the new extended life wipers proved that this pump can run 500 hours at 3500 RPM with a light oil mist and still maintain full vacuum! Compare that service life with any other brand pump and you'll find nothing else comes close to lasting that long.

With GZ Motorsports Vacuum Pumps, there is no need to spray brake cleaner into the pump between rounds to keep the internal vanes from sticking, a necessity with all other brands of pumps because they aren't designed to run in an oily atmosphere. Unlike the others, GZ pumps use a proven vane design that doesn't stick!

Quieter Operation... Want to run a vacuum pump on a street car? You don't want an annoying click-click-click to give away what you have under the hood. GZ Motorsports vacuum pumps are much quieter than the competition. Other pumps make a loud clicking sound as they rotate when they work correctly. GZ operates quietly and stealthily under your hood without annoying clicks.

GZMS pumps are manufactured in in Glencoe, CA. After assembly, each pump is tested on our pump dyno at 3500 rpm. During testing, Red Line racing oil is run through them, so when you get your pump you will see "blackened" oil at the inlet and outlet ports. This is normal and due to the break-in process. GZMS vacuum pumps all show the test vacuum and date tested on the part sticker on the pump.

🛠️ Skip's Guide to GZMS Vacuum Pumps

GZMS makes a solid vacuum pump, but like anything mechanical, it needs some TLC to keep running smooth. Let me break it down for you.

🛢️ The Oil Factor: Keep That Pump Slick!

These GZMS vacuum pumps are designed to let a little oil flow through 'em, and trust me, that oil’s their lifeblood. It's gotta be there to lubricate those wipers at the vanes, or you're looking at some serious wear and tear. Now, here's a little tip from ol' Skip: synthetic oil tends to give those pumps a longer life. Run 'em dry, though? You're asking for trouble. The friction between those Rulon wipers and the carbon fiber vanes will chew things up faster than you can say "rebuild."

Warranty Warning: Don't Run 'Em Dry

GZMS stands behind their vacuum pumps with a one-year warranty, but let me tell you—if you run that pump dry, kiss that warranty goodbye. They’ll know if it’s been run dry, and you’ll be out of luck. So, keep the oil flowing and your wallet happy.

Pulley Ratios and RPM Limits

Here’s where things get technical. Typically, you’re looking at running that pulley at 64% of crankshaft speed. That’s usually achieved by using a 3.5" Crankshaft Pulley paired with a 5.5" Pump Pulley. But listen, don’t push that pump past 6000 RPM. Sure, some folks get away with running those Sportsman vacuum pumps faster, but that’s risky business. Stick to the recommended limits unless you like living on the edge.

Managing Vacuum Levels

These GZMS pumps can pull more than 20 inches of mercury (in. hg.) in vacuum, so you’ll likely need a vacuum relief valve.

Not sure how much vacuum to run? Well, safe bet is to keep it around 10 to 12 in. hg., but talk to your engine builder—opinions vary.

Some competition engines run over 20 in. hg., but that’s when the motor’s built to handle it. Don’t push it unless you know what you’re doing.

đź“Š Data Loggers: Your Down-Track Detective

For those high-output, power-adder engines, get yourself a data logger. It’s gonna track those vacuum levels when you’re roaring down the track. You should see vacuum increase as your RPMs climb.

If you see it drop off suddenly, you could have a ring seal problem. And let me tell you, sometimes not having a vacuum relief valve helps you spot those early warning signs of trouble, especially if you're logging the data.

Fine-Tuning Vacuum Levels

When you’re in full-blown competition mode, fine-tuning the pump RPM might be better than relying on a relief valve.

The idea is to help spot any ring seal issues as they come up. Again, have a chat with your engine builder or tuner before making any big changes.

🔩 Every Engine is Unique

Every engine’s got its quirks, and no two are the same. The amount of blow-by, the air leaks, they all factor in.

If you’re running low-tension rings or power adders like nitrous, superchargers, or turbos, expect more blow-by. That means you might need a bigger or faster-spinning pump.

🍺 Alcohol Fuel: A Different Beast

Running alcohol? That’s gonna throw another wrench in the works. Alcohol, especially when running rich, tends to lower the vacuum, so you might need a bigger pump than if you were running gasoline.

🔍 Finding Leaks: The Air Test

Here’s a little trick: pressurize the engine with air and check for leaks in the crankcase, valve covers, distributor base, timing chain cover, and dipstick tube.

Don’t overdo it—too much pressure, and you’ll blow out a gasket or seal.

🔧 Sealing the Dipstick Tube

If you’re still using a dipstick (and why wouldn’t you be?), you might want to pull it out when running the car.

Pop a rubber vacuum plug over the tube to seal it off, but leave it so you can still check your oil. It’s a small thing, but it’ll help keep your vacuum strong.

🛠️ Every Build is Different

At the end of the day, engines vary. Everything from how fresh they are, the ring end gap, cylinder prep, and ring design can affect how much vacuum you’re gonna pull.

This here’s just a guide based on years of working with GZMS products and hearing from customers in the trenches.

⚠️ A Word of Caution: No Guarantees

Now, GZMS makes good products, but motorsports, as we all know, is a wild ride. They’re not gonna guarantee performance or safety—just part of the deal when you’re in this game. You take on all the risks when you're pushing the limits of your engine.
