Owner's Review Stark Varg - First Customer Review!

[fsfs]

You seem like the person to ask... Can you help me understand the claimed torque specs for a Stark Varg?
In my mechanical world, Horsepower is calculated by multiplying torque x RPM and dividing by 5252. So for the Varg - 665 lb-ft x 14200rpm / 5252 = 1797 horsepower.
Clearly that cannot be right, so what am I missing?

The marketing material quotes rear wheel torque which is subject to gearing ratios. The motor itself has a peak torque of about 80Nm. It can deliver this torque from 0 RPM to about 7000RPM. From 7000RPM to 13000RPM the torque will gradually drop from 80NM to 45Nm. These are just rough numbers from memory, but they should give you an idea of how the system behaves. IIRC, the gear reduction from the motor shaft to the counter shaft is 3.5:1 and then whatever sprocket ratio to the rear wheel.

Thank you, @fsfs, this is perfect.

Could someone please count the number of teeth in the Varg's primary gear reduction?
