When should you shift when racing?
So here's the answer – the point to change up a gear for maximum acceleration is the point when you'll get better acceleration in the higher gear. In other words, the point when you'll generate more torque at the wheels in the higher gear. Or redline, if that comes first. 332 = (226 x 9549) / 6500 or, 332Nm. What RPM should you shift in a race? Shift gears between 2,000 and 2,500 RPM for optimal engine efficiency.
