2011 Professional upgrades: power, range and charger upgrades (to Lithium) by SHIFT Electric Vehicles LLC.

2008 Professional onversion: to SLA completed, by Northwest Electric Vehicles.

This car was featured in Excellence magazine, won trophies at shows and has been the envy of many builders. Too many professionals were involved with this car to list, contributing to paint & body, all leather interior, motor, clutch, controller, suspension, brakes, etc.,.
MotorAdvanced DC 9 inch Series Wound DC
Customized to handle higher voltage and current by our friend Jim Husted at "Hi Torque Electric".
DrivetrainTrans-axle is a 5 speed Porsche 901, with internal bracing by motor Meister Inc.

With the power this car has, it's no surprise that a CV joint failed during initial drive tests. New half-shafts/CV's (intended for V8 conversions) were installed and have held up well.

The common clutch slip issues that powerful conversions often experience, was solved with a KEP (Kennedy Engineered Products Inc) stage III double disk clutch and a new lightened flywheel. The flywheel has no ring gear since a starter motor is not needed. It should be noted that this is the first double disk clutch that KEP has made for a 914.
ControllerCafe Electric Zilla 2,000 Amp (replaced a 1000A)
Extra High Voltage Zilla 2,000 Amp controller & hairball and 4/0 motor cables.
Batteries102 CALB/Skyenergy SE100AHA CALB, 3.20 Volt, Lithium Iron Phosphate
3D CAD was highly leveraged to model various cell sizes, configurations and containment. This quantity of CALB 100Ah cells were selected for a number of reasons. Pack fit, voltage, capacity and in part, peak current output, reliability, safety and cost.

New box & lids were designed by SHIFT EV, and fabricated by Hot-Rod builder Mike Asbahr at Benchmark Fab & Finish.
System Voltage326 Volts
ChargerElcon 6KW LiFePo4
Mounted remotely under the front-most battery box. Charger status LED indicator signals are routed to a location near the charge inlet connection, using fiber optics.
HeaterDirect Electric, 3000W total.
DC/DC ConverterIota DLS 220-45
InstrumentationCustom built in-dash gauges, plus an E-Meter a subtle BMS "over/under voltage" LED, and a motor "over-temp" LED.
Top SpeedNew top speed unknown/untested. Prior to the upgrades described, top speed was >100mph.
AccelerationThe controller has been limited to 1400 Motor amps (@150 motor volts). At these settings we estimated 0-60mph in about 5 or 6 seconds. 2000 Amps are available at the flick of a stylus.
Range133 Miles (213 Kilometers)
A controversial topic since there are many dependencies that affect range.

For clarity, the low voltage alarm testing test described below, was in dry weather over 2 days. Average daily temperature was 57 degrees F. During low voltage alarm testing, Neal Meyer joined me, a friend who contributed many hours to this project.

The test drive covered a total of 133 miles before we were able to sag the pack (driving up a hill) enough to set off the first low cell alarm. The alarm threshold was set at 2.5 volts, on any given cell.

The first 50 miles of the test was efficient driving and mostly highway miles at 55-65mph. After that was less conservative with higher peak speeds for another 60 miles. Traveling farther than planned, we ran out of time and had to park for the night. The next morning, without additional charging, the test drive was completed. The final portions of the test drive was aggressive acceleration and hill-climbs. When the alarm did signal at 133 miles, highway speeds and good acceleration were still no problem. No worries about being stranded when the test was stopped. Assuming a 100 mile range is a very safe DOD to insure many lifecycles for this pack. On this trip, 110mi=83%DOD based on actual battery capacity/performance.
Watt Hours/Mile245 Wh/Mile
This is calculated from the trip data described in the Range section above. It would improve a bit with more conservative driving. 51mph is the average speed considering city and highway miles driven that trip.
EV Miles
Start:149,984 Miles (241,324 Kilometers)
Current:151,984 Miles (244,542 Kilometers)
Total:2,000 Miles (3,218 Kilometers)
Seating CapacitySeating for 2 adults. Some storage in front and rear. Targa Top fits properly in the trunk.
Curb Weight2,850 Pounds (1,295 Kilograms)
As measured by digital truck scales.
TiresMichelin, Energy Saver GREEN X, AS P185/65R15
Conversion CostFar more than the asking price.
Additional FeaturesAdjustable charger current.

J1772 inlet with safety shutt-off circuit.

The set of Revolution Millennium Rally Wheels are rare 15x7's, built for 914's.

Bilstein heavy duty shocks and heavy duty springs all around.
