Im new to the ev world. I was kinda forced in this world when I found out about the epa new laws for cars and modding. I figured now is the best time to learn a new skill. I researched how the motor works,the controller works, and battery's. Im on a budget and looking for a good motor to handle high torque and about 130 140 mph for a car weighing at max 3000lb (still looking at chassis). my question is what specs I should look at for the motor and controller to handle it all? I'm doing all work and welding my self. Again im on a $3000 budget for parts.


Ps any comment is a good comment trying to learn as much as I can.

Hi,
For $3000 not much you can do, batteries are pretty damn expensive.
130, 140... hmm. Leaf motor running to transmission might do the trick. About 110hp (which can drift pretty well because of the quick torque, 187 lb-ft or so). That powertrain won't run over 2k ready to go.
But then you have $1000 for batteries, which will get you about nowhere. You'll need to spend at least 3k on batteries unless it's okay to go 30 miles tops (and wayy less at high speed/high load).

As far as the EPA I feel you. Getting classic tags on my turbo project car this year so I don't have to do emissions for another 5 and then after that maybe I'll be banned from ever driving it again :(

As far as your drift car, budget is unrealistic. The idea is great though, no shifting and smooth endless torque will definitely benefit drifting.

One thing I noticed autocrossing an EV is that with no engine noise, you can hear exactly what the tires are doing and there is so much feedback there that is lost normally.

I agree.

Yes, but it seems like drifting would need sustained significant power, and the power ratings commonly published for motors are typically for brief duration. It will important to ensure adequate cooling and to plan for a realistic sustained power output.

Thanks its a sad

Absolutely right I wanted to keep the intercooler to help.with that some how in corporate it into the design then I stumbled on to using a nissan leaf motor and battery pack still iffy on that.

See now that would be something to experience, the videos I watched so far felt like the sound was missing. it was different to get usto.
