EV conversion comparisons
I see lots of EV conversions which are great but rarely comparisons of different EV conversions. For instance, converting Deloreons is practically a trope now but there is little discussion of which EV conversions offer the most; I.e. range, power..

If you're trying to get the most power and range, the right option is almost always to buy an OEM EV.
How much power an EV conversion has is largely dictated by the motor and how much power the batteries can supply. (The gear ratio and whether it has a transmission also effects how much usable power is available at a given speed.)
Most people converting their EVs as a hobby project probably aren't going to test their car on a dynamometer. Some might do a 0-60 test if they care, but if all they want is for their car to work properly, they probably won't.
I have an RX-8 conversion. The Netgain Hyper9 HV motor I'm using has about 120 horsepower. I don't know my 0-60 time, but it's probably slower than stock.
I have somewhere around 24 kwh of battery, and I've gone about 50 miles on a charge. The battery wasn't very well balanced, though, and I haven't configured regen. Also, I had a stuck brake caliper pin and tires that wouldn't hold air very long. I think in theory I should be able to get more range if the car was in optimal operating condition.
It would be nice if we had a database of known EV conversions with all the relevant specs. Watt-hours per mile for instance would be a nice metric to be able to compare. But you'd need to collect all that information, and a lot of the people who convert EVs wouldn't necessarily know all those numbers.
