These are some simple calculations for Horsepower, Displacement, and Compression Ratio.
These figures are approximations and should not be taken as absolutes, only baseline figures.
Horsepower from 1/4 mile ET or Trap Speed:
Compute from ET
Compute from trap speed
Please enter the weight of the vehicle.
Please enter the 1/4 mile ET of the vehicle or
Please enter the trap speed of the vehicle.
This is the approxiamte HP of the vehicle at the rear(or front) wheels.
Please enter the bore of the engine.
Please enter the stroke of engine.
Please enter the number of cylinders.
This is the approximate displacement of the engine.
Enter the combustion chamber displacement.
Enter the cylinder displacement.
