Port Flow Analyzer 0.wmv  Intro to Port Flow Analyzer, starting by installing from the CD, starting up the program from the Desktop Icon, and unlocking the program to take it out of demo mode.

Port Flow Analyzer 1.wmv  Intro to Port Flow Analyzer, background on how flow benches work, different types of benches Port Flow can work with, you can do test manually or automatically with a data logger.

Port Flow Analyzer 2.wmv  Intro to our Black Box II data logger, getting it up and running and communicating to your computer, troubleshooting communications problems.  Includes basic info on SuperFlow FlowComs.

Port Flow Analyzer 3.wmv  Discussion of various input screens in the Port Flow Analyzer and how their settings affect the test you will run, what data is recorded, etc.  These screens include Flow Bench settings (very important) and a discussion of Master Bench Specs settings, sensor Calibration Details screen (very important if you are using a data logger), Test Conditions (very important), Head Specs (especially those which affect the test), and Head Details (for recording info only).  As changes are made, we show how this changes the data logging screen on the main screen.  We also show how you can manually edit the rows and columns of data on the main screen.  We also show how to enter some factory calibration specs for the Black Box II into the Calibration Details screen.

Port Flow Analyzer 4.wmv  Discussion of calibrating a Black Box II sensor with a known pressure reading from a manometer.

Port Flow Analyzer 5.wmv  Shows starting an actual test with the EZ Start Wizard and running the test with a Black Box II (a FlowCom would be quite similar).  It shows setting ranges, valve lifts, controlling test pressure, and pressing <F1> to record the data.  It also shows recording port velocity readings, and how the data gets updated on the main screen.  The data and graph on the main screen let you spot problems right as you are running the test.

Port Flow Analyzer 7.wmv  Describes starting an actual test with the EZ Start Wizard and running the test manually, just typing in the data.  It also describes additional features for the SF110 type of bench (blower centered bench), which needs temperature corrections, and has a correction factor used in its calculations based on flowing a known orifice. 

Port Flow Analyzer 8.wmv  Discussion of the EZ Flow system (Black Box II electronics), including calibrating it with a known orifice and running a test with the EZ Start Wizard .

Port Flow Analyzer 9.wmv  Discussion of analyzing data, data and graph on main screen, the meaning of L/D (lift vs diameter ratio), making various types of reports (columns of numbers), using engine specs to produce an Engine Performance Potential report, emailing a report using a PDF format, printing a report with your company logo (and loading a company logo file and company name into the Preferences screen), correcting CFM to a different pressure (like 10" vs 28") than what you measured the head at.

Port Flow Analyzer 10.wmv  Discussion of more report types, like Calculated data including valve and flow area, flow coefficient and flow efficiency, picking different cylinders/average of all cylinders/all cylinders for the report, cylinder to cylinder comparisons, and tests comparing results from 2 different heads (tests).

Port Flow Analyzer 11.wmv  Discussion of exporting reports as ASCII files, for example a file that could be used in EXCEL (tm). 

Port Flow Analyzer 12.wmv  Discussion of making graphs, overlaying different tests using the History Log, overlaying different cylinders, more info on the History Log, different graph features like zooming, the cursor to pin point different values on the graphs, the very useful Flow Area graph combining a cam profile with a flow curve, saving a Graph Format to save your graph settings and scale factors for use later, port velocity maps, printing options like including various data with the printed graph, printer choices, color/monochrome, etc.

Port Flow Analyzer 13.wmv  Discussion of more graph features like the History Log, different graph  line styles including some fancy 3D graph types (good for magazine articles), and emailing graphs.

Port Flow Analyzer 14.wmv  Discussion of opening and saving files from an external drive like a memory stick (good for transferring files from one computer to another), creating a new test name, adding a new folder for storing tests, finding a particular test using the Filter option, using the Advanced feature to move around on the computer to find a test, reading in a file stored with Metric units even though your program is set up for English units, deleting a folder or file.  More file commands include Import and Export (make an ASCII file from a report) and Backup and Restore, email a test file.  Also covered are the Edit, Preferences and Help commands at top of main screen.

Port Flow Analyzer 15.wmv  Shows copying ALL files from one computer to another.  This would be like you bought a new computer and you wanted to get your files transferred to the new computer.  We use the Port Flow Analyzer as the example.  We also show the Port Flow Analyzer's actual Backup and Restore features and how that can do the same thing but more efficiently by just copying the data files you need.

 

Engine Log Book to CR Calc Movie  Shows how you can use the Compression Ratio Calculator in the Engine Log Book to simplify Compression Ratio, deck height "stack up", bore, Piston Dome, and many other engine builder calculations.

 

Valve Spring Tester Basic Movie  Shows how you enter the calibration specs, perform a test with video of the actual tester in action, and use some of the features of the Basic version of the software (the Quick Check feature in the Plus version).

Valve Spring Tester Advanced Movie  Shows how you run a full test in the Plus version of the software.  After setting up and running the test, the demo shows the various ways to analyze the data with graphs and reports, print options, and more.

Automatic Valve Spring Tester Movie  Shows the automatic (pneumatic) spring tester in action.

 

Cam Analyzer Test Prep Movie  Shows several options and features of the Cam Analyzer software for doing various types of cam measurements.  Then it shows step by step how to start a test for measuring a cam with the Cam Test Stand.

Running a Cam Test A Movie  This movie follows what happens directly after the steps in Cam Analyzer Test Prep.wmv, in testing a cam on the Cam Test Stand.  Have your computer volume turned way up, as some of the audio gets pretty low when I set the microphone down to show some of the hardware.

Running a Cam Test B Movie  This movie follows what happens directly after the steps in Running a Cam Test A.wmv, in testing a cam on the Cam Test Stand.  Have your computer volume turned way up, as some of the audio gets pretty low when I set the microphone down to show some of the hardware.

Finding TDC w Bridge Movie  For most cam measurements, the Cam Test Stand measures lift, Duration, acceleration rates, etc.  However, it does not know how the cam gets installed in the engine, so the actual timing (centerlines, opening and closing events, etc) are based on what the user tells the program about the #1 Cylinder's Intake lobe's timing (like #1 Intake has a 108 centerline).  The Cam Test Stand's optional TDC Checking Bridge lets you measure the dowel pin or key location on the cam.  Knowing how these are timed in the engine, it is now possible to know how the cam will be timed in the engine.  Have your computer volume turned way up, as some of the audio gets pretty low when I set the microphone down to show some of the hardware.

Starting/Running a Test with Virtual Follower  The "Virtual Follower" feature is very useful when you have a cam to measure, but do not have the correct follower, like roller diameter.  It is also used when you are measuring a cam for an OHC Rocker Arm valve train, like a "finger follower" for the 2.3L Ford, which has a complex geometry and the Rocker Arm Ratios changes dramatically during lift.  The movie also shows how you can save a file to a new name so you have 2 copies of the same data and make graphical comparisons of the same data being simulated different ways.
