Drag Racing Gear Ratio Chart

Drag Racing Gear Ratio Chart - Web what is the optimum gear ratio for your application? Some folks find it difficult to understand the numbers you see in the table (gear ratio), so let’s compare it to car. 1/4 mile top end speed. Web so what about race gear selection? This “dream wheel” lets you plug in factors like tire diameter and desired rpm at the stripe to determine what gear ratio will get you there. Web to correctly gear a vehicle for drag racing, the final drive ratio (axle ratio) must be selected first, before choosing a torque converter, transmission, or transmission ratios. Enter the tire size diameter and the target vehicle speed in mph. You’ll also need to consider a gear that allows you to produce maximal watts for the length required. Ideal 1/4 mile gear ratio. Web there are three elements involved in determining the best gear ratio:

Ideal 1/4 Mile Gear Ratio.

Enter the tire size diameter and the target vehicle speed in mph. If your max hp is at 6300 rpm use 6300 for the rpm. 5000 rpm), press calculate, and you’ll get the right ratio without the guesswork. Web to correctly gear a vehicle for drag racing, the final drive ratio (axle ratio) must be selected first, before choosing a torque converter, transmission, or transmission ratios.

However, the ideal gear ratio can vary based on your vehicle’s power and tire size. In contrast, a numerically lower gear ratio like 3.08:1 offers better fuel economy but slower acceleration. Below is a gear ratio chart showing what your engine rpms would be at 65 mph based on your tire diameter and differential gear ratio in third gear (1:1 transmission ratio). In drag racing, different vehicles and engines require specific gear ratios that complement their characteristics.
