The Latest in Racing Vacuum Pump Technology
While most vacuum pumps may appear to work the same, the fact is there are major differences on the inside, where it counts. Our 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 diecasting, only available from GZ Motorsports, forms the core of the new pump with much closer tolerences than previous models enhancing it's air flow potential. Closer tolerences in the new diecasting allow the Pro Pump to generate 26% more air flow than similar sized competitors pumps! Updates also include improved and beefed up port locations, totally rebuildable bearing sections and long life wipers.
As with all GZ Vacuum Pumps, Rulon Wipers are still used exclusively as it's the best material to use for tough hot and oily applications that we've found. In fact, this pump can suck in and spit out anything but metal without sticking! In fact recent durability testing we've conducted with our 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 whose pumps make a loud clicking sound as they
rotate, when they work correctly. GZ operates quietly, and stealthy under your hood without annoying click clicks...

GZ Vacuum Pumps
generate
higher vacuum and are
more
reliable than the others...
You won't be needing to take a GZ Vacuum Pump
apart all the time to clean it because our
pumps are not afraid of moving oil through
them! The carbon fiber vanes and Rulon wipers
seal better than anything else available which
translates to less overall operating cost for
your race car. Another feature you'll like is
that they cost less than others, that's
right you get more pump for less money...
Choosing a Vacuum pump for your racing motor
is not a one size fits all situation - Make

needs so you can make the most horsepower for
your application!
 "We've tried several other vacuum pumps over the years, we even put two of another very well known brand on at the same time, but none compare to the GZ Motorsports Super Pro pump,"

We build all kinds of racing engines in our shop at Nickerson Performance and the GZ Pump is absolutely the best pump on the market. It runs and runs and never breaks or needs maintenance. We've found it pulls more vacuum than you would expect from a pump of it's size, and it also does it consistently. The pump on my personal Beretta idles at 10" and pulls 15" from start to finish with the Super Pro pump. I've tested all the vacuum pumps available, and hands down GZ pumps make more HP than any other pump on the dyno.The closest thing to a GZ pump is the Enhanced Moroso Vacuum Pump, it works ok, but the Moroso does not pull as much vacuum as the GZ, and doesn't last near as long.
All of the other brands of pumps (and we've tried them all) have problems making vacuum at lower RPMs until the vanes come out and start to seal. This variation makes you wonder where the vacuum is when you're dynoing an engine - and you can imagine what kind of inconsistency it leads to on the race track. When you complain about this to the manufacturer, they always blame it on something you're doing, but low and behold, when we mount up a GZ pump on the engine the problems go away!
"Considering how steady the pump pulls
and keeps the mist out of the chambers, I
have no doubt that we gained at least 25
horsepower at the flywheel..."
"I am really impressed with the
GZMS VP101 Sportsman Vacuum pump and kit.
We installed it on a 347 cubic inch Small
Block Ford build up we did for Ford Muscle
Car Magazine. When we dyno’d the
motor it made 702 hp without the vacuum
pump and 735 hp with the pump.
That's a 33 hp gain with just the
pump. We also noticed an increase in
the rpm at which peak horse power was
made."

"The time ticket enclosed shows a 6.47 at
109mph 1/8 mile without the pump. With the
vacuum pump the other time ticket shows a
6.19 at 114mph 1/8 mile. About 3 tenths
and 5 mph faster. I run this FED in all
high gear. It has a powerglide with a trans
brake that will lock in high or low. I am
very happy with my GZ Motorsports Sportsman
Vacuum pump and am purchasing a complete
Sportsman Vacuum Pump Kit for my Blown SBC
in a 55 Chevrolet that I both drag race and
drive on the Street (occasionally)"
