Just tell us which car you have, enter some info about your gearing, motor and batteries, and we'll do the rest. Record your estimates to compare different car setups, and if you have a speed gun, you can record your actual top speed along with the estimate. Info you'll need: - Pinion gear teeth - Battery cells (or voltage) - Motor Kv rating - Tire diameter (we can fill this in based on your car type) Info we probably have already based on your car: - Spur gear teeth - Transmission ratio Please note, our top speed estimates are just that - estimates! We use a formula that works in theory (in perfect, not real-world conditions), but every car and all driving conditions are different, so expect some variation from real measured speeds.
