* Need to know your vehicle speed at a given engine RPM?
This calculation comes useful when targeting a certain engine RPM with a given tire, trans-gear and differential gear-ratio for highway cruising or quarter-mile passes.
* Engine RPM @ MPH
This one is the opposite of the first one. This one comes handy to experiment with different tire-size, trans-gear and differential gear ratio combinations to reach a certain vehicle speed and keep the engine RPM within a given range for controlling MPG, engine noise, exhaust tone, etc.
*Gear Ratio.
Useful when wanting to determine the gear ratio present in your differential without disassembly.
* Gear Set Ratio.
Found a set of gears at a swap-meet or the junk yard and don't know the ratio? Enter the number of teeth for both the ring-gear and the pinion and you're done!
* Overall Tire Diameter.
Very useful before making a final decision about purchasing wheels and tires! Test before you buy! Get accurate dimensions by combining different tire sizes and wheel diameters, profiles and widths!
* Elapsed Time.
Predict your 1/4 Mile E/T by providing the engine HP and race-car weight!
* Horsepower @ E.T.
Don't know your engine's power? Easily get a good approximation based on the car's weight and 1/4 mile E.T.!
* And if this isn't enough, you don't need to surf the net looking for the required trans data! It's included inside the App with more manufacturers added constantly!
* Save money by experimenting before making permanent mods!
