If I were tryign to achieve a fast road legal EV I would be looking more towards a clubman/7/caterham or even an MX5. Plus you will want to run something like 300V to get the top end power.
So I think you need to be aiming for about 150KW or better (real achievable power, not an optimistic sales specification). It is using around 70KW of power in a car half the weight of a 240z. My cars performance can be seen by googling "Full Charge Motorsport" To achieve higher speed I would need to increase my voltage requiring mre batteries and more weight which is not what I need. But that is OK by me because my EV is only designed for sub 60mph performance. But then the ICE 240z would beat it from 45mph up.
My experience has been that a fair battery pack givin 500amps at 170v in a 1600lb car with a full gearbox gives slightly better than ICE 240z acceleration up to about 45mph. But only if you choose the right motor, controller and batteries. What exactly are you wanting to achieve? The torque of the electric motors can give you some good launch. I am a current Z owner (1x 240z, 1 x 280zx) both are still ICE. Anyone willing to help me crunch some numbers? If the performance estimates suck, I might bolt on an extra AC motor to my rear AUX shaft. Given the insane torque curves of EV's, I don't think I can trust the online "0-60" calculators that assume a ICE power curve.Īssuming traction isn't an issue, with optimally geared manual, what kind of acceleration can I realistically expect here? 0-60? 0-100? The controllers easily handle 120v (and 130v max).īasically, I'm anticipating ~260 torque & around 140 HP. I plan on running at least 110v nominal with a pack that sags far less so the horsepower should be higher (torque extending further up the RPM curve). Their dyno test sags down to 87v at ~1300A peak amp draw with whatever power supply they were running. The company lists the motor dyno performance at 96v here. It will likely not exceed 2500 lb post conversion.
It will be manual transmission with a curb weight of 2300 lbs (ICE equipped). I've been piecing together parts for a while now, and I'm in the market for a Datsun 240z as the donor car.
