Ihan vaan omasta mielenkiinnosta vastailen...
Eikö peränvälityksen tihentäminen juuri pienennä Stall speediä.
Tiheä väli = auto liikkuu kevyemmin
Pienempi vastus eli stall speed laskee
“We must remember that the torque converters’ output comes from fluid pressure vs. resistance,” Gill said. “The heavier the vehicle weighs, the more resistance that there is in moving it. Conversely, a lighter vehicle takes less resistance to move. This brings us to the resistance against the pressure that tries to move the vehicle. The more resistance (weight) against the torque converter, the higher the stall speed to move that weight. The less resistance against moving the vehicle, the lower the stall will be in the torque converter.”
“If our test vehicle has a 3.73 gear ratio with 26-inch tires, then the gear ratio will run true because of the tire height.
If we had changed the 3.73 gear to a 4.56 gear ratio, the torque converter would in fact stall less due to the lower resistance needed to move the vehicle.
With the 3.73 ratio, if we went from a 26-inch-tall tire to a 27.5-inch tire, the roll out of the tire will give us 3.55 rear gear output and performance. That is one whole gear ratio less. (Note: NOS and Superchargers/turbos like the longer or lower gears to give them the time needed to load up).
The same is true for the opposite, if you went to a 24.5-inch tire from the 26-inch tire, then your ratio will increase (that is one whole gear set more) to 3.90 output and performance.
