    I'm thinking to convert a 1998 Mazda Miata to EV :) Can a Warp 9 motor connected directly to the transmission shaft move the vehicle even in a incline grade? What should be the voltage? Best regards.

    Hello, I had a idea for a car in my yard I have had for a while. It is a 1983 7 series BMW. This is still a very sturdy car just not had a want to work on it. I think it is a fuel system issue. This car is a automatic and I have considered setting the transmission up for electric motors like the...

    I am trying to get a quick fix on the complexity of my chosen vehicle - a 95 BMW 318ti (E36). Does anyone know if I will be needing the ECU and needing to do tricky things to fool it. I'd like to keep my conversion real simple. I intend at the moment to dump the automatic transmission and go AC...

    I'm considering converting a fwd car. My current EV is 1:1 in 4th gear, while it's a bit sluggish off the line, it does just fine otherwise if I never leave 4th. I was wondering if anyone has ever just mounted a motor to one wheel? How successful was it and how bad where the drawbacks? Oh...

  9. mounting motor to axle?

    Technical Discussion
    I've been looking around for a while, but haven't seen anything on this yet, so excuse me if I'm asking a redundant question. I'd like to do an AC system with direct drive on a small truck. If I can drive with a single gear ratio, the drivetrain will only add weight and take up space, so I'd...

    :) My students and I have begun a "new" type electric car project! It will be brutally simple. We have replaced the rear axle on a '91 Geo Prism, with the rear axle from a Subaru Justy. The Subaru rear suspension is especially well suited for this format. The Subaru rearend is floating with CV...
  11. Connecting directly to the driveshaft?

    Technical Discussion
    I'm having considerable trouble trying to even get my transmission disconnected from the flex disk that its bolted to ... as a result I don't know if I'll even be able to take the transmission apart to tell what's wrong with it, let alone get it put back together right if found reasonably...

  14. anyone running direct drive?

    Does anyone run direct drive? I'm working on a custom sand rail project and it was suggested I try to run two transwarp 7/9 motors directly to the half shafts. Anyone have experience here or any thoughts?
