First off, this is just planning for the long term since I won't have money or time for at least 8-9 months. I have been doing lots of research and I decided to post because I can't seem to find direct answers for some questions I have.
The idea is to make a college project out of my e30 once the motor kicks the bucket. I love my car and my goal is to convert it to electric drive while maintaining all of its current performance. This means top speed of 100 mph or so, 0-60 in 9ish seconds and curb weight of 2700 or better.
Right now my planning and research is in the general phase and I don't have any details in mind but I have a few questions about electric conversions.
First, what power do I need out of a motor to equate to about 120 hp and 170 ft-lbs that I have in my current ICE? Ive seen people using 24ish hp motors and I've seen racing guys using dual 150kw motors so where is the in between? I plan to take this car on track so I want to maintain the performance it has right now but I can't afford some monster motor either.
Second, Is it unreasonable to use the motor in a direct drive or is it cheaper to have a simpler controller and just use the tranny? I would love to do away with as many components as possible to make the car more efficient. I also want to fit the motor where the tranny is now to give the car better cg height and weight distribution.
Any suggestions and or links are appreciated. I have been having trouble finding good resources on understanding EV performance so if you guys wouldn't mind posting some information for me then I can better grasp what it will take to get this project rolling. Thanks!!
