wow man. you have really pulled off a great job.
and a great car to . if you sell the engine will it pay for the conversion? if so you are a complete legend. just another 2 years and top quality lifepo4 will be really cheap. you can get pretty good ones now for $16 each for 3.3volt and 10 a/h
what would the cost to replace the distance capacity you have in those batteries there?

I've thought about doing an EV project but my problem is during the week I drive 22 miles at 70mph and another 16 miles at 55 mph round trip to work. Around town driving consists of a 14 mile round trip to the grocery store. At the moment an EV wouldn't be practical for the number of batteries needed to maintain the highway speed needed.

Most EVs use around 200wh/mile when up to speed. It's the weight of the vehicle that consumes power to get up to speed but with regen you can get up to 50% of that back when slowing down again but you must have AC to do that.
When at speed it's rolling resistance and aero drag that consumes energy. 77 miles requires about 15.4 kWh of battery capacity, unless you're converting a 2 ton SUV with the aerodynamics of a building!
Something like the Tesla has 54 kWh

Okay. Nuff said. You are a man for all seasons, dude. I just wish I had your range of skills in hand. Milling, welding, electrical/electronics. Are you selling how-to videos?
Thanks for the inspire.

Interesting! So by controlling torque you could set it up to have peak torque at 5000rpm etc – apart from the lack of noise gas car drivers wouldn't notice the difference!
