Vehicle

1971 Porsche 914
High Performance Electric Vehicle, Our everyday driver

Motor

Netgain Warp 9 Series Wound DC
Reliable and simple.

Drivetrain

Original Clutch and 5 speed manual transmission.

Controller

Cafe Electric Zilla ZIK-LV
What a great controller.

Batteries

48 Thunder Sky TS-LFP180AHA, 3.32 Volt, Lithium-Polymer
So far I'm getting 200 Ah out of them. I expect the actual Ah to decrease over time.

System Voltage

159 Volts

Charger

Manzanita Micro PFC-30
Five different charging plugs/adapters are carried in the car including a J-1772.

Heater

Two 110v/240v blow dryers. Set to 240v & handles removed.

DC/DC Converter

Iota DLS-55

Instrumentation

EV Display by Clean Power Auto in a customized gauge cluster. I added indicator lights and the "EV Display" to the car's original fuel gauge instrument. Lights include "Parking Brake", "Energy Low", low pack voltage, low individual cell voltage, motor overheat and Zilla over heat. See the photo on right. Original Tach and Speedometer.

Top Speed

106 MPH (170 KPH)
Verified by FL State Patrol (don't ask)

Acceleration

0-60 in 8.9 seconds with my weak driving skills. A lot faster than the original. My best time was done using only 3rd gear. In 1st and 2nd the stock tires just spun to much.

Range

163 Miles (262 Kilometers)
Actual mileage during a mix of highway and city driving. This result is after I replaced the weakest cell after 4000 miles and did an real life range test.

Watt Hours/Mile

230 Wh/Mile
Estimated
Some interesting measurements I took on level ground:
40mph 40 amps
50mph 57 amps
70mph 135 amps
70mph 170 amps with top off & windows down

EV Miles

Current:	5,030 Miles (8,093 Kilometers)
	As of 4/22/2012

Seating Capacity

2 adults

Curb Weight

2,540 Pounds (1,154 Kilograms)
Actual measured weight. I'm pleased since it's under the manufactures max curb weight of 2690#.

Tires

Standard. I've heard that the low rolling resistance tires might add 10% to the range. That will have to wait until I wear out these cheap Yokohama's.

Conversion Time

4 months

Conversion Cost

Car: $3500 purchase price. It was drivable and had a new paint job but some rust. Subtract $1300 in parts sold. (engine, exhaust, fuse panel, gas pedal, fuel tank, etc.)Final cost: $2200. Conversion parts: $17,500.

Additional Features

VoltBlocher cell level monitoring system: Outputs warn driver if an individual cell voltage drops to low; cuts back charger output if an individual cell voltage gets too high.

All interior, underneath, and trunk metal surfaces rustproofed and painted. (Should last another 40 years!)

The EV equipment doesn't take up any space in the rear trunk so it is fully useable. Front trunk usable due to plexiglass battery cover.

Great acceleration, fun to drive! Great range, Takes 6 hours to fully charge using 240 volt outlet.
