

elapsed Time –

Enters or calculates the vehicle’s

quarter-mile dragstrip Elapsed Time, in seconds.

Given entered quarter-mile dragstrip Elapsed Time

and speed, calculates the vehicle’s eighth-mile drag-

strip Elapsed Time and speed. Given entered HP

and vehicle Weight, calculates the vehicle’s Elapsed

Time and speed for both the quarter-mile and

eighth-mile dragstrips. When the appropriate envi-

ronmental conditions are entered, both methods cal-

culate the vehicle’s Horsepower correction factor

(

HPc) and provide the Motorsport Standard

Atmosphere (MSA) adjusted Elapsed Times and

speeds.



Drag Coefficient (Drag Coeff) –

Enters the vehi-

cle’s Drag Coefficient when correcting for wind.

See Appendix A for typical body styles and asso-

ciated Drag Coefficient values. Default value is

0.35.



Miles per Hour –

Enters or calculates speed in

miles per hour. Given entered speed, assumes

value as the vehicle’s quarter-mile dragstrip speed

and calculates its eighth-mile dragstrip speed.

Given entered HP and vehicle Weight, calculates

the vehicle’s speed for both the quarter-mile and

eighth-mile dragstrips. When the appropriate envi-

ronmental conditions are entered, both methods

calculate the vehicle’s Horsepower correction factor

(

HPc) and provide the Motorsport Standard

Atmosphere (MSA) adjusted speeds. Given Gear

Ratio, RPM and new Tire Diameter (HP and

vehicle Weight not entered), calculates current

speed.



Kilometers per Hour (km/h) –

Enters or calculates

speed in kilometers per hour. Functions the same
as , displaying calculations in km/h instead.
