The Wilderness EV site I looked at shows a 120V kit with 6.7" series DC motor (looks like D&D) and 400A peak controller for about $4600. I doubt you can get 90 HP out of that small motor very reliably, and you certainly can't get 90 HP out of the controller. A 5000 lb vehicle would be very underpowered with it. Their 144V kit uses an FB4001 9" motor and 400A peak controller. If you don't care about how long it takes you to get to highway speeds the latter would eventually get you there. If you used 12 12V batteries for nominal 144V you might get sag to around 135V with 400A current, or about 72 HP. Figure around 20% power loss in the motor and controller and that leaves about 58 HP.
In reality, if you want a car that performs more like a typical ice powered car, you will have to spend more money and purchase a higher power controller like a Zilla or Evnetics for the FB4001 motor, or better, use a WarP9 motor. To get an ev that meets your satisfaction usually requires a lot more homework. Lots of time searching suppliers for different components available, reading about conversions on the evalbum and on blogs as well as here and diyelectriccar, to educate yourself on what kind of performance to expect from given components for a given car. You will end up with something you can drive with the above kits after a lot of custom work on the adapter, motor brackets, and additional parts like vacuum pump for vacuum assist brakes, but it will be an arduous process with mediocre performance in the end. Also, people can't help you much if you don't inform them of what kind of performance you want, meaning how far do you want to go, how fast, what 0 to 60 mph time, etc. If you spend on the order of $5000 plus battery cost, and use lead acid batteries, expect large 0 to 60 mph time and short range (< 40 miles, and that is in warm weather when the batteries are new). That's fine with some folks, who for example have a 20 mile or so round trip commute on secondary roads, so such a kit will work for them. If you dream of dusting young guys in their ice vehicles off the line at a traffic light, expect to pay more. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/1986-Pontiac-Fiero-conversion-tp4668635p4668672.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
