What do the owners of these cars have in common?
When setting up their cars for the dragstrip with new engines, they used:
Straightline Acceleration Simulator
Straightline Acceleration Simulator will help you choose the best parts combination for your drag racing or top speed competition car, truck, or motorcycle. Try different tire sizes, engines, differential and transmission gear ratios, shift points, torque converter and clutch slip/stall speeds, and much more, then see the resulting 1/4 or 1/8 mile ET and speeds to find the best combination before spending money on parts. This will help you get the best combination on the first try, potentially saving hundreds, if not thousands of dollars on parts that may not be quite right for your vehicle.
1/4 or 1/8th mile drag racing
Calculate 1/4 or 1/8th mile ET and speed before getting to the track
Find the best gear ratio for your application
Try different shift points
Use any manual or automatic transmission with up to 8 gears
Specify torque multiplication for the torque converter
Input measured engine dyno data at either the flywheel or driving wheels
Try different weather conditions. Temperature, altitude, humidity, and barometric pressure have a large impact on ET's.
Land speed racing
Find the top speed of the vehicle
Run an entire acceleration run over a distance you specify. Your vehicle may not reach its top speed before the first timing marker! This software will help you know ahead of time.
Find the best gear ratio
Try different transmissions and tire sizes
High performance street cars, trucks, and motorcycles
Do these questions sound familiar?
"So I'll get 20 more horsepower and 15 lbs-ft of torque. What exactly does that mean in terms of real performance?"
"Which is better? A new carburetor and intake setup that gives a 30 horsepower boost, or a switch from a 3.08 to 3.73 gear ratio instead?"
"How much improvement will a "high stall" torque converter really provide?"
"What will a gear change to do my highway cruising RPM?"
"Will the tires handle my next modification?"
Straightline Acceleration Simulator will help you find the answers to these and other questions, BEFORE spending any money on parts.
Input information for:
Chassis/Body -Weight, aerodynamic data, wheelbase, and more
Tires -Including growing tires
Transmission -Up to 8 gear ratios, either manual and automatic. More than 70 transmissions' ratios are pre-loaded in the menus
Differential ratio & drive type -Front, rear, and full time locked center differential all-wheel drive supported
Weather conditions -Specify air pressure, temperature, relative humidity, and altitude
See detailed information output including:
The engine can be specified three different ways:
Manual entry @ 500 rpm steps -Specify a torque/power curve at either the flywheel or driving wheels.
Manual entry @ any step -For more precision, input torque/power data in a more precise time step. Great for "peaky" engines.
Or, just in case you don't have engine data, get an estimated torque/power curve using some of the engine parameters themselves with QuickEngine Builder. Let the properties of gas dynamics help!
