electric motor

Do they make larger electric motor that can boost the horsepower of the crz!?

[91CRXTC]

Not yet that I know of but I'm sure some one will in time

[andrewr]

No word of a "larger" motor for it but there is a lot of rumor for potentially increasing the output of the stock one, from what I've read elsewhere on the forums, possibly double its stock output.

Only thing is that you'll run into energy storage issues, but maybe Li-Ion would come to the rescue?

[andrewr]

Yes, my hope it that when the origional battery pack needs replacing there will be an li-ion replacement option. Until the warrenty wears off its all just speculation and talk for me of course, but as long as we are at it I wonder if something as simple as thicker/more conductive power wire from the battery pack to the motor would improve torque numbers?

To me that makes sense because the electric current will be stronger or con it just drain the battery faster with little hp/tq gains

Monster Cables maybe??

[andrewr]

Well either way I am going to make a guess that if/WHEN popular modifications to the electric motor's output are available, like somehow turning up the controller(?), bigger cables will come into play to provide more amps for more torque. I don't know what size wire they are using stock but I know if you want more power you allmost always need more conductive wire in allmost any application. Of course any such mod will result in draining the battery somewhat quicker, but for those who are into it I think the main idea is:
"Hey, we've got this big battery pack with a butt-load of joules stored in it, how do we get as much of that power as possible to the wheels?"
My brain, which I've said tends to be out there sometimes, is wondering if theres another way to put that power to the wheels besides the motor.
What I mean is, say you over-drive the stock motor and put out 55ish more ft/lbs of torque. Thats great, but maybe we can do better. What if, for just a small amount of time (say 15 seconds) you dumped a couple hundred amps out of the battery pack into a purpose built electric motor that spins up a small-ish supercharger? I might guess such a setup, while probably complicated, could potentially feed the engine a 4-6 PSI boost without taking any energy directly off the engine to create it.
It would be hella-hard on your battery if you did it very often and maybe a bit much extra weight of components to drive around with... but I'd still like to know if it would work... call it "Electric Nawz"

The electric motor "draws" power from the batteries. The stock ima motor can not produce more power then it already does. If battery capacity is increased the power will still remain the same but the charge will last longer. If the stock ima motor is replaced with a larger motor it will draw power faster from the stock batteries. So if the ima motor is replaced the batteries will also needed to be replaced.

Not necessarily true.. there's a motor controller in there to control the voltage/current applied to the electric motor and manage/control the power the electric motor delivers in conjunction with the ICE, to the drivetrain. The controller max current draw is probably set quite a bit lower than its max handling capability to achieve reliability goals (heat management) and working LIFE for the battery system.

It's probably quite likely that the system could develop more power at the cost of battery life and reliability.

Someone will undoubtedly unlock it's potential (no pun intended)!
