Want to know your 1/4 (Quarter mile) performance? Want to know your engine power based on 1/4 mile performance?
Changing tire or wheel size? Want to know how will it affect the highway rpm's or the 1/4 mile performance?
Easy to know with this calculator! The Calculator for Drag Racing!
★ 1/8 to 1/4 mile E.T. Converter. Easily convert short track times to 1/4 mile times!
★ Predict weather and track conditions right from this app.
★ 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! A must for drag racing.
★ 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.!
