If you think adding more gears to a stock gearbox is as simple as “just squeeze in another ratio”… this video will change your perspective.

In this deep dive, I break down why you cannot randomly add gears to a transmission. Every gear ratio must be calculated strategically to ensure:

• Progressive acceleration through each shift
• Minimum RPM drop between gears
• Engine stays close to its peak power band
• Smooth power delivery
• Top speed is still achievable in the final gear

More gears don’t automatically mean better performance. If the ratio spread is wrong, you’ll either fall out of the power band or compromise your theoretical top speed.

In this video, we explore:

How gear spacing affects acceleration

Why RPM drop matters after every shift

The relationship between the torque curve and the ratio selection

How to mathematically design gear progression

Why OEMs carefully engineer gear ratios instead of “adding more gears”

Whether you're building a race car, modifying a stock transmission, or just want to truly understand how performance gearing works, this video connects theory with real-world vehicle dynamics.
