| 5 Ways of Building Torque |
| |
| Cubic
Inches |
| Stroking
creates more displacement, and displacement means
power. |
| |
| Compression |
| More
displacement makes it easier to produce high
compression without massive domed pistons. |
| |
| Lever
Action |
| A
longer stroke is a longer lever acting on the
crankshaft, thus providing more torque. |
| |
| Pressure
Power |
| Longer
stroke creates faster piston speeds, which means
that the piston can create a more accurate
pressure drop to fill the cylinder more
thoroughly at low rpm for torque. |
| |
| Rod
Angularity |
| Increasing
stroke without increasing rod length increases
torque because the piston-speed dynamics and rod
ratio conspire to create more cylinder pressure
at maximum rod angularity. When this occurs, the
rod has the greatest mechanical advantage over
the crank. |
