What does a 4/10 gear ratio mean?
Count the number of teeth on the ring and divide by the number on the pinion and you have the gear ratio. A higher number means that the wheels turn farther in relation to driveshaft speed, therefore making the car faster. With 3.08 gears the rear tires turn 3.08 times for every time the driveshaft turns.
What’s the gear ratio of a Mustang 4.10?
Additionally, with a gear ratio of 3.73, the pinion will turn 3.73 times for one turn of the ring gears, and for a 4.10, the pinion will turn 4.10 times. Another good visual way to understand this would be how many times your wheel spins compared to the rotations of the driveshaft.
What’s the RPM of a Mustang at 70 mph?
However, the car feels like a dog getting off the line. A friend of yours suggested to jump to 4.10 rear gears to help with acceleration. This calculator will help you determine that with 4.10 gears, your engine will be spinning at 2,368 RPM at 70 mph.
How many gears does a Mustang pinion turn?
So for every turn of the ring gear, the pinion will turn 4.11 times. Additionally, with a gear ratio of 373, the pinion will turn 3.73 times for one turn of the ring gears and for a 410, the pinion will turn 4.10 times.
What’s the RPM of a 4.10 gears car?
This calculator will help you determine that with 4.10 gears, your engine will be spinning at 2,368 RPM at 70 mph. This equates to slightly less fuel economy and slightly more strain on your engine when driving down the highway.
Additionally, with a gear ratio of 3.73, the pinion will turn 3.73 times for one turn of the ring gears, and for a 4.10, the pinion will turn 4.10 times. Another good visual way to understand this would be how many times your wheel spins compared to the rotations of the driveshaft.
So for every turn of the ring gear, the pinion will turn 4.11 times. Additionally, with a gear ratio of 373, the pinion will turn 3.73 times for one turn of the ring gears and for a 410, the pinion will turn 4.10 times.
Why do you need more gears on a Mustang?
Auto Mustangs like a little more gear than their manual brethren. The reason for this is auto transmissions typically have lower gears and with the converter, need a little more differential gear to get up and running.
How does the gear ratio affect top speed?
To turn the wheels at 1000 RPM, it now takes 3700 RPM from the engine to maintain the same 40 MPH speed. The engine is revving higher for the same speed, and thus our top speed is reduced because we are now closer to redline for the same speed as before. Acceleration is increased because the engine now enters the power band sooner.
