Quote "Never heard that before, I always heard longer stroke = more torque." Yes, longer stroke does = more torque. And yes longer rod = more torque. Longer stroke increases displacement.
Longer rod, increases leverage over the crankshaft.
A 2mm longer stroke will make more power than a 2mm longer rod. "After all there's no replacement for displacement." Longer stroke,,,, Good. Longer rod,,,, Good. Longer stroke AND longer rod,,,,,Great.
Stroker crank question.

This reminds me of a statement I once read on a helmet.
"Want more inches, Stroke it." :eek:

Jay is right, and so is annimal... But a 2mm stoke will outweight anything taken away by a 2mm shorter connecting rod. ANd in the end, you have a bigger motor.
In other words, I will take a 2mm stroker crank with a 2mm shorter rod over a a stock sized crank with a 2mm longer rod.
The "torque" of a longer rod is not felt from the very bottom end of the rpm band, it is ususally good in like a flat track situation, where the rpm's never go very low. It gives you more pull out of the corners than a stock length rod. This was done due to engine size limitations.

I think annimal was saying longer stroke with a longer rod is better than a longer stroke with the shorter rod.
I believe a 2mm stroker crank only needs 1mm shorter rod. If you do the math a longer rod = more torque in the same displacement, but I doubt there would be anything detectable by seat of the pants in our engines with 1mm rod lenth differances
