* 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 dont know the ratio? Enter the number of teeth for both the ring-gear and the pinion and youre 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.

Dont know your engines power? Easily get a good approximation based on the cars weight and 1/4 mile E.T.!

* And if this isnt enough, you dont need to surf the net looking for the required trans data! Its included inside the App with more manufacturers added constantly!

* Save money by experimenting before making permanent mods!

* Free lifetime updates! Download now!
