Compute gear ratios accurately for racing setups. Input your data below for instant calculation results.
| Driveshaft | Tire Diameter | Engine RPM | Final Drive | Transmission Ratio |
|---|---|---|---|---|
| 60 | 28 | 6000 | 3.73 | 1.00 |
| 60 | 30 | 6500 | 3.55 | 1.50 |
| 55 | 26 | 7000 | 4.10 | 2.00 |
Gear Ratio = Engine RPM ÷ (Tire Diameter × 0.2618) ÷ (Transmission Ratio × Final Drive Ratio)

1. What is a gear ratio? The gear ratio is the ratio between the engine speed and the wheel speed, determining torque and acceleration.
2. Why use Summit Racing parts? Summit Racing provides reliable components, ensuring precision and durability for all racing applications.
3. How to input tire diameter? Measure the full diameter of the tire in inches for accurate calculation.
4. Can I use this for street cars? Yes, the calculator can be applied to both racing and street vehicle setups.
5. How does final drive affect ratio? A higher final drive ratio increases torque at the wheels but reduces top speed.
6. Is engine RPM critical? Yes, engine RPM is a key factor in calculating gear ratio and performance.
7. Can I save results? You can download results as CSV or PDF for record keeping.
8. What if my input is wrong? Double-check values before submission; incorrect inputs yield inaccurate ratios.
