I've been calculating the advantages of moving from a 4.10 to a 3.31 gear. Assuming a 26" tall tire with 1:1 final drive ratio at a constant speed for simplicity, the engine would spin 19% less with the numerically lower gears.
For fuel useage, a slower spinning engine would have a shorter injector pulse width, so it's tough to use the same fuel consumption when calculating the different consumption rates. I.E an engine spinning at 2500 rpm will use less fuel than an engine at 1750 rpm, assuming similar load.
How would I go about figuring fuel consumption?
...yes, it's slow at work today.
