How does cid make power?
Simply for more torque. Street guy area.
I see what your saying but also say that even though the stroker takes longer to make that rotation, the added torque maybe of some advantage as well as getting to peak power earlier & shifting sooner.
Street guys leave more on the table with horrible cam selection than they gain with stroke. I get it. “Street” guys want to smoke their tires and think that’s actual power. It’s not. And “street” guys love to lug the engine around and stuff like that. That’s why they can’t run as much compression as they could. And that’s a power loss too.
Ok, let’s talk this through. Stroke length does not matter when talking RPM. That’s because it doesn’t matter how long the stroke is because RPM is RPM.
Lets say we have a 3 inch stroke and a 4 inch stroke engine. The 3 inch stroke engine has a shift RPM of let’s say 8k and the 4 inch stroke engine has a shift RPM of 6k.
In a 1/4 mile, they both travel the same distance. That means that the 8k engine (lets say they both run 11.00 times) had more power cycles across that distance. Not because the longer stroke takes longer to RPM, it’s because it has less RPM. And that means it has less power cycles across the same distance.
And the power cycles (power stroke) are what move the car down the track, or down the road or what ever.
Think of it in terms of Diesel engines. They have huge torque numbers and low horsepower numbers. That same Diesel engine will have far less power cycles than a gasoline engine. That’s why the horsepower is low.
Power cycles is what matters. The other three strokes don’t make the car move.
