EV Calculator

FYI - there is a handy EV calculator to help you in determining how your conversion project may turn out. I originally was told that it was pretty inaccurate, but now I see it was pretty close to reality.
I saved the EV Miata specs for your enjoyment.
Here is the link:

Now, it doesn't take RPM into account, which used to make me distrust the results, but just disregard the stuff about 90 mph is first gear. The Warp 9 has a red line of 8000 RPM.

Planning, planning, planning...

I’ve been thinking about converting a car for a while almost a year now. I’ve researched other conversions, joined some EV mail groups and read a few books. I decided to focus on converting a Miata, they are light, aerodynamic, cheap and plentiful. I put together a spreadsheet to compare different components and voltages. And the best combination of speed, range and cost got me came out at 156 volts with a 9” WarP and a Zilla 1K. Next was to sell the concept to my wife. Luckily she is pretty understanding of my eccentricities and went along with the idea.
