What makes more power bore or stroke?
The short answer is that a bigger bore is generally the best way to get more power. It creates more space, allowing for bigger valve openings, which in turn can bring more fuel and air into the cylinder.
What is the best bore to stroke ratio?
Rod Ratio: The Math
We hear a lot of engine builders shoot for a ratio between 1.5:1 and 1.8:1 on a street motor, with 1.75:1 considered ideal, regardless of application. The most highly developed four-stroke engines in the world – Formula 1 and motorcycle engines – have rod ratios of more than 2:1.
Does a bigger bore mean more compression?
All of these components have a direct affect on compression. For example, as the bore becomes larger, compression increases. If you use heads with a smaller combustion chamber, the compression will increase. Even changing to a thinner head gasket will increase the compression ratio.

Does a bigger bore mean more hp?
A bigger bore with a shorter stroke also allows an engine to rev higher, which creates more horsepower. Conversely, a long stroke is generally better for fuel efficiency, because it reduces surface area during combustion.
Does boring an engine make it weaker?
Boring an engine involves using machines to widen and taper the cylinders. From a performance standpoint, boring an engine could give you more horsepower and torque, as it will change the engine’s displacement. Engine displacement refers to the swept volume of all pistons inside the cylinders of an engine.
Does boring out an engine increase horsepower?
Boring an engine involves using machines to widen and taper the cylinders. From a performance standpoint, boring an engine could give you more horsepower and torque, as it will change the engine’s displacement.
Do longer connecting rods make more power?
A longer rod makes more torque with the same piston force, and since it’s less angular than a shorter rod, reduces sidewall loading and decreases friction. All of this adds up to more power.
