WinGears 3.04

[ Home ] [ Up ] [ Gears 2 ] [ Gears 3 ] [ Gears4 ] [ Gears 5 ]

The WinGears program now comes in two versions:

Regular $195 -  Full gearing analysis including an inventory of gears.

Advanced $395 – Add acceleration capability and advanced analysis incorporating torque-induced tire slip.

 

The Gear Calculator  program computes and displays information to assist in the gearing of automobiles.  Input consists of gear ratios (either by tooth count or ratio), rear end ratio (either by tooth count or ratio), spur gears (if any), tire size (either diameter or circumference), and RPM shift point.  With this data the program computes and plots the relationship between RPM and MPH as well as the RPM drop between gears.  The program also produces a standard gear chart of MPH vs. RPM.  This plot shows and displays the maximum MPH in each gear (at shift point) as well as the RPM drop between gears.

Basic Gear Calculations

Gear Inventory

The use of an inventory including transmission gear ratios as well as rear end ratios, spur gears, tire sizes and Engine RPM allows you to quickly see what alternatives are available for any gear.  The above inventory shows alternative 4^th gears for the gear combination shown above.

This feature saves time in selecting gears.  You may want to lower 4^th gear 200 rpm but you are restrained by what gears are available.  The above inventory shows that a 35:36 will reduce the 3-4 split from 1133 rpm to 923 rpm and give a top speed of 170.20 mph rather than 175.07.
