The Hot Rod Calc Road and Strip
Performance Calculator is the world's first elapsed time (ET)
calculator with built-in motor building and performance solutions. At
the track, calculate how temperature, elevation, pressure and moisture
will affect your times. In the garage, instantly calculate how changes
in your car's engine and fuel system will affect performance. Away from
your cars and other vehicles it can even double as a standard
calculator. Any way you need it, the Hot Rod Calc puts street and strip
performance in the palm of your hand.

The World's First ET Predictor Calculator
The Hot Rod Calc Road and Strip Performance Calculator is a handheld,
affordable, accurate and rugged ET Prediction calculator specifically
designed for hot rod owner/builders, bracket racers and engine
builders. It can help at the track or in the garage with easy solutions
to help figure out how to make vehicles perform better and how to
predict the results of changes in everything from engine displacement
and compression ratio to weather, tire sizes and gear ratios. The built
in formulas help the auto enthusiasts with instant answers without
having to remember complex formulas or look up in tables or charts. At
the track, racers can see how weather and elevation will affect their
times so they can instantly predict dial-ins using current track
conditions. They can predict elapsed time and top speed for ¼ mile or ⅛
mile runs. Inputs for track conditions include temperature, absolute
pressure, humidity, and elevation; inputs for the race vehicle include
vehicle weight, horse power, frontal area, and drag coefficient. ET and
trap speeds are adjusted for motorsport standard atmosphere and can be
adjusted for wind speed and direction. Enter current local elevation
and calculate Air Density Index and Density Altitude. In the garage,
engine builders and tuners can easily see how changes in a car’s engine
and fuel system will affect performance and solve dozens of "what if"
scenarios in seconds, including calculating compression ratio, engine
displacement, carb size, volumetric efficiency, mill amount,
horsepower, torque and more. Calculate how changes to a car's engine
and fuel system affect performance with no confusing formulas, charts
or computers. The utility conversions are very handy for those who need
to handle fluid conversion (oil / fuel / etc.), temperature, torque and
weight conversions.
Standard Features:
- Predict elapsed time and trap speed for ¼ mile and ⅛ mile runs.
- Automatically calculate Brake HP given Torque and RPM, ET and Weight or MPH and weight.
- Enter
or calculate local track conditions, including absolute pressure, air
temperature, moisture, elevation, air density index and density
altitude, wind speed and direction and predict their effects on your ET
and speed.
- Calculate speed given vehicle weight and HP or tire diameter, gear ratio and RPM.
- Instantly
see how changes to any of 8 engine measurements can increase your
Compression Ratio -- deck height, dome volume, chamber volume, gasket
thickness, gasket bore, bore and stroke and/or milling the heads.
- Enter
target engine displacement and current stroke to calculate the new bore
or enter displacement and current bore to calculate new stroke.
- Fluid
conversions for gallons, fluid ounces, cc, ml, liters, temperature
conversions for Celsius and Fahrenheit, weight conversions, metric and
imperial conversions.
- Calibrate the calculator's mechanical efficiency setting to more closely match a car's time.
- Calculate fuel correction index to determine new jet flow requirements.
- Works as an everyday calculator.
- Quick reference guide.
- Two 1.5 volt LR-44/A76 long-life batteries.
- Full one-year limited warranty.
