Stroker Tips & Tech Advice


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.
