I missed it, how much improvement did it do, whats the output of the assist and what is the battery capacity?
Ive had the idea to add an electric motor in the loop of my insight as well as back feed the ima motor using the 4 kilowatt enginer pack, however I had a lot of people, poo-poo the idea.
If it would work on a standard car that offers the fuel cut in its computer, it should really help in a newer insight or hch as these cars disconnect the lifters so the valves stay shut to reduce pumping losses.
Mike Debrowski had done some work on a 5th wheel as a pusher and showed a mini van getting 70+ mpg and that was with its engine running in gear so fluid still pumped through the tranny.
If you decide to do it yourself, you can find 48 volt lifepo4 backs with charger and bms online as well as speed controllers and motors. My idea was to limit it to a thousand watts, so I had a min 2 hour run time with my 4 kilowatt kit and maybe 3.5 tops. Having one that did regen required a much more expensive controller.
