Circle Track Analyzer

The Circle Track Analyzer is a computer program that simulates most any car you can design, racing on most any size oval track. It will let you predict and understand the effects that various modifications have on handling, performance and lap times.

Features:

• Mouse driven interface compatible with Windows 95/98/Me/XP/2000/NT/Vista
  Full 32 bit version uses long, more descriptive names for saving files.
• Detailed front suspension layout screen, very similar to our popular Roll Center Calculator.
  
• Detailed rear suspension layout screen.
• Many specs can be picked from general descriptions, rather than from detailed engineering specs. However, engineering specs can still be entered.
• On screen help by simply clicking on any input spec.
• New graphing features let you graph MPH, acceleration rate, engine RPM, just like a data logger used by the pros. Options include graphing up to 6 tests, zoom, shift, modify titles or labels, different background colors, line styles, etc.
• A log of the last 25 runs is kept to track your modifications. You can select runs from the log to keep longer to recall or graph in the future .
• Loads power curves automatically from the proper Windows versions of Engine Analyzer.
• Print most all menus and screens.
• Feature to automatically find the best gear ratio for a particular track.
• Program can automatically "dial in" critical specs to match your car's lap times.
• "Corner Jacking" Screen to estimate the change in ride height and corner weights from adjusting (jacking on) springs.

V3.5 added these features:
You can now do an Symmetric Angled 4 Link rear suspension, like a Chevelle or Mustang.
You can create tables of Roll Center Position and Camber for various combinations of dive and/or roll
You can Graph the output from the Roll Center Position or Camber table above
Program now calculates Tire Track change (scrub) and draws tires correctly for this change
Program now calculates a " Handling Rating" based on the weight transfer of the front versus the rear. The car is "balanced" at the apex of the turn (not accelerating or braking) when theses weight transfers are equal.
The program can automatically find the roll center heights or spring rates or front roll bar rate to produce various balances between the front and rear weight transfer.
The "Corner Weight" (virtual scales) now determines the ride height and/or corner weigh changes from changing a tire size or moving/removing/adding weight (ballast).
Swing Arm length calculation has been added to the Front Suspension Screen.
You can link to our Circle Track Log Book. The log book is for record keeping of all your car's settings. With the Log Book linking to the Circle Track Analyzer v3.5, you can also keep records of calculated parameters like Roll Center (static and dynamic), Balance, Camber Gain, and more.
