This is for those of you who run at 1/8 mile dragstrips. The following is similar to that found on Page 2, but for an eighth mile.

While the calculated speed should be quite accurate (and useful for comparison purposes), the many variables which affect elapsed time cannot be adequately covered here. For this reason, I have chosen not to display the calculated elapsed time.

Change the following information to fit your car.

When inputting transmission gear ratios, simply repeat the last valid ratio to complete all six form spaces.

The answers are displayed when a tire type selection is made. It is necessary, then, to repeat the tire type selection whenever a change is made in the spreadsheet.

engine rpm at rear wheel power peak =

maximum rear wheel power =

effective tire radius =

car weight =

axle ratio =

maximum engine rpm (shift rpm) =

     

number of transmission gears =

first transmission gear ratio =

second transmission gear ratio =

third transmission gear ratio =

fourth transmission gear ratio =

fifth transmission gear ratio =

sixth transmission gear ratio =
