Calculate gear ratios, find optimal transmission setups, and determine speed-to-RPM relationships. Perfect for automotive tuning and performance optimization.
Gear ratios determine the relationship between input and output speed and torque. A 3:1 ratio means the driving gear must turn 3 times for the driven gear to turn once. This trades speed for torque - you get 3 times the torque but 1/3 the speed.
In automotive applications, multiple gear ratios in the transmission work with the final drive ratio to provide the optimal balance of acceleration and top speed for different driving conditions.
Use close ratios and match top gear to track's longest straight. Aim for peak power at the end of straights.
Balance acceleration and cruising ability. Keep highway RPM between 2000-2500 for best efficiency.
Use tall gears and deep overdrive. Target 1500-2000 RPM at cruise speeds for maximum efficiency.
Optimize for peak power through each gear. Calculate to hit rev limiter just past the finish line.
