Vehicle1983 Porsche 944
Originally a 2.5L 4-cylinder gas guzzler.Front engine, rear wheel drive with transaxle at the rear for almost perfect weight distribution. This car has enough space for 18kWhr of batteries in the front engine bay, and probably another 40kWhr in the rear if required.
MotorNetgain Warp9 Series Wound DC
Controller ElectroCraft 800A
Designed and Manufactured by ElectroCraft in North York using far superior IGBTs than even a 1000A Zilla. This controller has been fully tested to it's maximum current rating.
Batteries50 Thunder Sky 100Ahr, 3.60 Volt, Lithium-Polymer
Battery pack arrived successfully (one of the last shipments from EV Components). All cells were fully functional, and are now protected with an on-cell BMS system
System Voltage180 Volts
Charger ElectroCraft 1200W charger
This charger will be specifically designed to match the charging profile of the LiFePO4 batteries. For our large battery pack, this is a little under-powered, but we are limited to a standard household 15A receptacle.
Heater1500W ceramic heater at 180V. This should easily keep off the winter chill. Not sure how we'll be ducting the air around now that the dash is gone.
DC/DC Converter Electrocraft 5A Cross-charger
We'll keep a standard SLA battery on board to keep the accessories running, and top it up with this charger.
InstrumentationOriginal gauges are going to be rewired to work with the new equipment. Speed and RPM is straightforward, and hopefully we will get the original L/100km gauge up and running too.
Top Speed130 MPH (209 KPH)
Estimated top speed based on standard gearing and motor rpm
AccelerationShould be around 6 seconds for the 0-60. Very speculative right now though. This would be quicker than the original 944 performance too.
Range60 Miles (96 Kilometers)
Estimated mileage from 160Wh/km.
EV Miles
Start:93,000 Miles (149,637 Kilometers)
Current:93,000 Miles (149,637 Kilometers)
Total:0 Miles (0 Kilometers)
Seating Capacity2 adults.
Curb Weight2,300 Pounds (1,045 Kilograms)
Estimated final weight. Using the LiFePO4 batteries will allow us to bring the final weight down to significantly less than the stock weight of ~2900lbs. We are also doing a fair amount of weight reduction work as well, including replacing some parts with fiberglass, and stripping out the interior. For EVs, adding lightness is crucial.
Tires205/55/16 for now, although we'll be putting on some performance 245s soon. This may reduce mileage but will also increase our acceleration significantly.
Conversion Time~300hrs so far. We have spent a lot of hours developing the BMS system with ElectroCraft.
Conversion CostTotal cost is estimated to be around $17k. Incentives in Ontario may reduce this, although it's not clear yet if they apply to conversions.
Additional FeaturesWe have a number of optional upgrades planned, including adding a set of supercapacitors to reduce battery stress, and a heavy diet of carbon fibre. We're kicking ourselves for not buying the new Warp11 HV now, so we may be starting another conversion to house our Warp9, and still get the Warp11 HV for the 944 - we'll see.

We are approaching completion, or at least drivability. Getting insurance may take a while longer, which will give us time to add on the superficial extra's to make this Porsche EV a real head-turner.

Once this flagship electric 944 is up and running we will be taking orders for the next conversion. Take advantage of the upcoming Ontario electric car incentives and let us make your electric car.
