Predict 1/4 and 1/8 mile drag racing performance with this mobile version of Straightline Acceleration Simulator from Performance Simulations before buying expensive new performance parts for your car, bike, or truck. Find top speed, 0-60 mph or 0-100 kph, and plenty more.


This tool runs a full vehicle dynamics simulation right on your mobile device in the blink of an eye. This is not a simple calculator like most other apps of this kind. The vehicle's state is computed every 1/1000th of a second for a three mile run. The resulting data output is produced from millions of calculations.


Also view detailed information on vehicle speed at each gear shift, tire spin information, as well as a detailed breakdown of performance sampling every 0.1 second of the run through the quarter mile.


Metric and imperial units are supported.


Model inputs:

-Vehicle Weight
-Drag coefficient
-Frontal area
-Wheelbase
-Center of gravity/mass height
-Rear weight distribution
-Up to 8 transmission gear ratios plus final drive/axle ratio
-Engine torque curve from 0-10,000 rpm
-Gear shift rpm
-Gear shift time
-Driveline efficiency
-Rear wheel, all wheel, and front wheel drive supported
-Torque converter stall speed
-Clutch launch/slip speed
-Tire grip/friction coefficient
-Tire diameter
-Tire rolling resistance coefficient



A more sophisticated Windows/PC version is available for purchase at http://PerformanceSimulations.com along with a free demo. This includes a built in engine simulation (QuickEngine Builder) and additional vehicle model parameters that are not available in the mobile version.
