Flow Quik FAQ PDF Print E-mail
Flow Quik

Where did the idea for Flow Quik come from?
The idea for Flow Quik originated from a suggestion made by David Vizzard combined with a request from one of our international dealers for an affordable alternative to standard flowbenches. David has evaluated Flow Quik and written about it favorably in his books and articles.
Does Flow Quik replace a flow bench?
Flow Quik was originally intended to be used as a supplement to a flow bench, or as a learning tool for beginning head porter who could not yet afford a flow bench. Still many owners are successfully using Flow Quik as their only flow bench.

There are differences: Flow Quik is faster, easier, and more productive. On the other hand, Flow Quik does not control the depression. Depending upon the capacity of your air mover, it may not use as high a depression as a flow bench, especially when at high lifts on large heads. The method that Flow Quik uses to adjust flow readings to a standard depression is not valid for all flow conditions, especially when the actual depression is very small.
Do I need the 2 inch Flow Quik or the 3 inch Flow Quik?
The maximum ACTUAL CFM of the standard 2 inch Flow Quik is 330. Heads that flow more than this at 28 inches, can still be tested at less than 28 inches and Flow Quik will provide flow values adjusted to 28 inches. Minimum measurable flow is 7 CFM.
The maximum ACTUAL CFM of the 3 inch Flow Quik is greater than 700 CFM. Minimum measurable flow is 17 CFM. If your air mover is too weak to supply what your head flows, you will be better off using the 2 inch model. The 3 inch Flow Quik does not include the flex hose that comes with the 2 inch model.

A combo unit is also available that combines both 2 inch and 3 inch flow tubes with one set of electronics.

Will Flow Quik work with two vacuums connected together?
Some Flow Quik users connected two vacuums together with a Y fitting to get higher depressions. They report that the corrected CFM numbers did not change, but at high flow levels the numbers were more stable. Many users have built their own air supply. You can purchase a set of blueprints with illustrated instructions for building an air supply and test plenum.
Does the size of the vacuum cleaner matter?
The size of the vacuum does not affect the value of the corrected flow numbers. At high flow levels the numbers will be more stable with a stronger vacuum.
How can I tell what the depression is?
Flow Quik has a second digital display for showing depression.  It also shows air speed for pitot tube air velocity probes and booster signal for carburetor tests. Can I use the data from Flow Quik software with other programs?
Flow Quik software uses the same data file format as Flow Pro. Flow Quik data files can be used directly by Dynomation. Other programs may be able to read Flow Quik reports saved in an ASCII file format.
How do I test carburetors?
Connect the carburetor booster signal to the “S” tap on the front panel and switch the bottom display to show pressure. The software has special modes for carburetor testing and data display.
What are the software requirements?
200MHz Pentium with Windows.  A USB port is required for connecting the Flow Quik measuring unit.
With the purchase of Flow Quik what else, do I need?
Shop vacuum or other air supply. The size of the head dictates the air supply capacity. Heads can be tested with a weak air source, but results are better with a stronger source. See Flow Quik Tips & Advice for help on building an air supply. You can purchase a set of blueprints with illustrated instructions for building an air supply and test plenum.

An adapter for connecting to the head which shrouds the valve in the same way that the cylinder walls do. Most Flow Quik owners are using standard flow bench style adapters.

A test plenum. This is a box on which to set the adapter. The box also provides a good place to put the depression pickup. The standard flowbench hole for mounting flowbench style adapters is a 5 inch diameter hole with a square 4 hole bolt pattern around it. The bolt pattern is 5 inches on a side. The hose from Flow Quik to the box should enter the box on the bottom directly beneath the 5 inch hole. Connecting the hose to the side of the box can produce an uneven pressure distribution at the 5 inch hole.

A pair of special weak valve springs.

A mechanism to open the valve and measure the opening.

Radiused inlet guide for intake ports (necessary).

Stub pipe for exhaust ports (optional but recommended for best results).

Pitot tubes for measuring air speed in the ports (only needed if checking air speeds).
