Why would you want to know this? I always figured the more the merrier.
I was reading the thread on the electric 914, and it reminded me of a car I saw years ago. It was a Huge Lincoln Town Car, but it got approximately 100mpg. To do this, the owner had removed the drive train, and put in hydraulic motors at the wheels. Then he put an huge accumulator and a l briggs and stratton engine from a lawn tractor driving a hydraulic pump. On level ground the motor could push enough fluid to keep the car at freeway speed, and slowly fill the accumulator. With a full accumulator, the available torque would absolutely roast the tires. But when the accumulator emptied, it wouldn't pull a sick whore off a commode.
What if a 914 were done this way? I did some calculations, and a 17HP motor attached to a pump that will push about 50Gallons per minute could run 2 5.06 cubic inch hydraulic motors without a problem, driving a 914 on stock tires about 60 mph. IF we add an accumulator to the mix, we should be able to really make it accellerate fast. Each motor is capable of about 125 ft/lbs torque. That's Per Wheel. The 17 horse engine would run at a constant speed, which is more efficent than accellerating and decelerating. With the proper valving, we could even make "closed throttle" coasting refill the accumulator.
Kinda hare-brained, but anyone else think this is doable?
