Appendix 5: New Features in
Version 3.2
Here is a brief listing of some of the features new in Version 3.2:
Program is now a 32 bit version, fully compatible with newer operating systems, starting with
Windows, 95, then 98, Me, XP, and 2000. This also allows you to use much longer, more
descriptive file names for saving vehicles, suspensions and engines. It is also more compatible
with newer printers.
The program is now designed for 600 x 800 or higher resolution screens. Screen colors are
also more compatible with Windows XP.
The graph screen is now larger, and generally fills the entire screen.
There is now a separate “Examples” folder for example engine files provided by Performance
Trends. New engines which you save will be saved to a separate folder.
File commands to save a vehicle file to a floppy disk, or open a vehicle file from a floppy disk.
This allows easy transfer of files from one computer to another.
You can now choose to list engine files alphabetically (as normally done) or by saved date, with
the most recently saved files listed first. This should make it easier to find recent files more
New Example Engines have been added, like Crate Engines.
The user’s manual is now available from inside the program by clicking on Help at the top of
the main screen, then Display User’s Manual. The manual is in a high quality PDF format
The Performance Trends website is now available from inside the program by clicking on Help
at the top of the main screen, then Performance Trends on the Web.
Several features have been added to make the process of picking example components,
calculating performance, making comparison graphs faster. Once an example has been
selected on an input specification has been changed, the <F5> key lets you progress toward
calculating performance and making a graph. Then the <Esc> key backs you up to the same
point as where you started. This is explained in more detail below.
The program now remembers the point where you picked an example component, so if you
choose to pick another, it will default to the last component chosen.
The ‘Flow Efficiency’ of the ports can now be calculated from up to 3 flow/lift points.
The calculation accuracy has been “tweaked”. Most evident changes are:
Low RPM torque is higher for some engine combos.

Spark knock simulation is improved for more realistic trade-offs between knock, octane
and power loss from spark retard.
The required spark advance for a particular engine has been improved.
Revised the BSAC calculation to be more consistent with fuel flow (not change so
significantly 'with weather conditions as done in earlier v3.0).
Very Rich gas as fuel option to help to reduce detonation.
On program shut down, the program now asks if you want your changes saved to the “Library
Copy” of the file you are working with.
Several features have been added to the graphs, including:
The Graph cursor now interpolates between points. This means that if one power curve
has results at 2000, 2400 and 2800 RPM, and another has results at 2000, 2500 and 3000,
the cursor will read both curves at all RPM points you ran, 2000, 2400, 2500, 2800 and
Figure A1 Calculation Menu for Flow
TDC and BDC labels are now
displayed on the Valve Lift graphs.
If you are using a cursor, the cursor
value is also given as, say “24 deg
You can now print graphs in color
or B&W with various styles of
dashed lines.
A Preference lets you turn off the
Graph always AutoScaling a new
graph. This means that if you have
found a set of scales you like, the
program will maintain them.
The powerful ‘Optimize’ feature at the
main screen lets you try thousands of
combinations of critical engine specs to
find the best combo automatically.
Hundreds of new example parts have
been added, including the entire Crane
Cams Catalog, Brodix, AFR, Edelbrock,
World Products, Dart and TFS heads,
more Import parts, motorcycle parts and
kart parts, and more.
New Printing options for reports,
including different Font Sizes and
omitting the “Starting Point

Suggestions” for cam and runner dimensions (in Preferences). “Starting Point Suggestions”
are now done much better through the “Optimize” feature.
New Printing options for graphs, including “Dot Matrix Printer Adjustment”, Width
adjustments and more (in Preferences).
Version 3.0 let you send a power curve to a vehicle program to be loaded and run in that
vehicle. Version 3.2 lets you do that also. However, that process requires several key strokes
and time. Version 3.2 lets you “Auto-Link” with a vehicle program of your choosing. AutoLink runs every power curve you produce through a vehicle program, and produces a summary
of the results. Now you can instantly see how a cam change, head swap, more nitrous will
affect ET or circle track Lap Times. At the time of printing this manual, Auto-Link was only
available for the Drag Racing Analyzer v3.2 and Circle Track Analyzer v3.2.
Figure A2 New Options at Main Screen
Example Engines are now stored
separately from vehicles you create.
Demo program can now be easily unlocked from Main Screen.
Windows Printer Setup now available from Main
Commands to Open From and Save To floppy drive makes it easy to transfer
vehicle files from one computer to another.

Figure A3 Optimize Screen to Have Program Try Hundreds of Combinations Automatically
to Find the Best One
1) Click on “Optimize”
to open this screen
2) Choose
which engine
specs you want
to Adjust to find
the best combo.
The more you
choose, the
better the final
combo but the
longer it takes.
5) Click here to start the process.
6) If the process is taking too long,
click Cancel and “de-select” some of
the engine specs to adjust.
3) Choose what
you want
Averages are
calculated for
entire RPM
range set in
Conditions on
Main Screen
4) Set what Idle
Vacuum is
required, the
more vacuum,
the more
“streetable” the
final combo.
7) When finished you can
click here to keep the
Adjusted specs. Otherwise,
click on Cancel to close out.
• All other specs during the Optimize process are at the current settings in the
individual Component menus.
• Average Torque and HP are calculated for the entire RPM range you have set in
the Calculate Performance Conditions menu. If you want to optimize the Average
Torque or HP from just 5000 to 7000 RPM, set this range in the Calculate
Performance Conditions menu before Optimizing.

1) Pick an example part, then
press the <F5> key to return to
component menu.
8) You will see your previously picked
Example highlighted, so you can pick
the next one in series, if you wish.
3) Press <F5> from here to
make a graph.
6) Press <Esc> to

return to the Test
Results screen
Note: You can just start at step 2, change a component spec setting, press <F5> twice to
get a graph, then press <Esc> twice to return to the component menu to make another
change. You may want to adjust Preference and Graph settings to make this process
more streamlined.

In Preferences, choose
which Vehicle Program to
“Auto-Link” to. At this time,
only Drag Racing Analyzer
v3.2 and Circle Track
Analyzer v3.2 will Auto-Link.
Click here to have system
locate the Vehicle Program
you have chosen.
The results of the New (current) Engine
Power Curve coupled with the Vehicle File
in the Vehicle Program produces these
results. The “Last” results are for the
previous Engine Power Curve coupled with
the same vehicle.
Click on these results to get a summary of
the New vehicle results as shown here.
You do not need to start the vehicle program; the Engine Analyze will do it automatically.
The vehicle file being used is the last vehicle you were working with when you shut down
the vehicle program (the vehicle that would be opened when you start the vehicle
A 2-3 second time delay is built in the Engine Analyzer to ensure reliable communications
when doing Auto-Link. You will not be able to click on Back to return to the Main Screen
before this delay is over. You may also notice the progress bar from the Vehicle Program
momentarily appear on the screen, indicating the vehicle program is running.
