Actually I made a mistake in my math.

2F @ 24V = 288W seconds
-or-
2F @ 24V = 2.88KW for 100ms
-or-
2F @ 24V = 28.8KW for 10ms

So if you were looking to add 29KW of power a $200 Capacitor would give you 29KW of "boost" for roughly 1/100th of a second.
-or-
200F ($20,000) would give you the 29kW of boost for one second.

Thus I imagine it's current capacity is as well, so adding another motor would be a problem without an additional controller.

Default Improve Cooling

The peak power that the motor & controller can handle is a function of heat dissipation. Improve the cooling, and you can improve the peak power. Futhermore, if you know that the motor & controller are starting cold, then they can run above the steady-state rating for a short time because the motor (and parts of the controller) have a large thermal mass. I really liked the GM patent where they sprayed a liquid directly on the power semiconductors - using phase changes to transport heat is very effective.

I want the AWD Volt that has two motors, one front & a copy in the back.

I would rather see a solution that reduces the Rds(on) resistance of the switching MOSFETs, lower DCR of the power inductors, etc., instead of just keeping it cooler.

It's already going to be plenty fast enough to get you more than enough speeding tickets.

Cool I'm sure plasma boy will have a few ideas

Watch John's vid of his 1972 Datsun beating a Corvette

I hope there will be an aftermarket for things like solar panels and extended batteries. The volts range is just a bit lower than my daily drive. It would be nice to have an upgrade option to make it complete the journey.
