Shown at the 1996 Phoenix APS Electrics, held at Firebird Raceway, Phoenix, AZ. Photo: Paul Compton ] Some History I am certainly not the first to use an electric powerplant in a 914. When engineers and hobbyists began converting cars in the 1960's and 70's, using parts adapted from other industries (aircraft starter-generators as traction motors, for instance), their attention inevitably fell on the Porsche 914. The first modern one may have been done in Hawaii, in the late '70s. There is also some evidence of an electric 914 running around Campbell, CA in 1984. [Photo #5. Caption: Number Thirteen runs for the Women's Electric Racing Team at 1995 Phoenix APS Electric Stock. Mary Ann Chapman, driver.] Inspiration Since #13 was built, she has inspired other 914 Evs. There are at least 15 either on the road or being built. In her original configuration, "the Thirteener" served as a model for the VoltsPorsche conversion kit developed by a small Northern California company called Electro Automotive. This kit includes all the parts and instructions needed to convert a stock 914 from gas to electric.(Electro Automotive is located in Felton, CA, tel: (408)-429-1989). They have flyers on the VoltsPorsche kit. [Photo - First VoltsPorsche, "Black Magic". This car was built in order to develop a commercial conversion kit for the 914. She also served as an "EV ambassador to the general public" by giving rides and appearing in shows. (EAA San Francisco Bay Area Electric Auto Rally, 1995) I worked together with Electro Automotive to build the first VoltsPorsche=2E I provided the donor car, a space-black 1976 2.0L. I also paid for the kit design/fabrication and helped assemble the final car. The donor car was a space-black 1976 2.0L. The result was VoltsPorsche One, "Black Magic", which went on the road in early 1995. This car demonstrated that #13's performance was no fluke by duplicating the range and acceleration of the earlier car. "Black Magic" has proved to be a reliable high-mileage EV. In the Santa Cruz mountains, the car has shown a working range of 40 miles, and recently completed a 46-mile test run. This included a 2300 ft climb from Santa Cruz up Empire Grade to Bonny Doon at speeds between 35-40 mph (this is the speed limit on these roads). "Black Magic" now lives in San Bruno, CA, where she has to tackle the steep hills characteristic of the San Francisco area. Photo #7. Caption: [Clare and #13 explain EVs to some interested young women] Do batteries make the car heavier? In some cases, yes. It depends on the kind of batteries used and how many=2E The trend is toward lighter Evs. Curb weights for finished cars can vary from 2500 lb to 3200 lb. (see car specifications below for details) [Photo #8. Jaws? No, Just Black Magic, showing how clean an electric conversion can be. Polypropylene battery boxes with hold-downs fit nicely into the 914's front trunk. Photo: Lee Hemstreet.] Can the 914 handle extra battery weight? Yes. The original 914 chassis is extremely strong. It was designed in a multi-cell structure to absorb and diffuse collision impacts. It also has two heavy box-beam channels running along the sides of the car, so that even with the roof off, a 914 has more chassis rigidity than a 911. People have walked away from 60 and 70 mph head-on collisions in 914s. In addition The car was designed to handle much more weight and power than Porsche ever gave it. Racers routinely drop big-block V-8s in Fourteeners and Porsche actually built two with a 908 racing engine. These cars are driven harder than any car on the road, since they handle so well, and they survive it. There are also chassis-strengthening kits, since some people do drive gas 914's so hard that the body can separate from the firewall at the rear shock-towers ("Flexy-Flyer syndrome). [Photo#9. Caption: New advanced sealed 12V batteries, such as the Electrosource Horizon, can fit quite neatly into the 914's "letterbox". Battery jugglers:, left, Ruth MacDougal, right Clare Bell.] [Photo #10. Caption: A closer look. The straps were added to facilitate loading. Since 914s are used a lot in competition, there are all sorts of after-market brake and suspension mods available. Some 914 racers upgrade their brakes to 911 calipers and rotors, which are 11 inch drilled disks and give better stopping power. That requires going to 5-lug 911 wheel hubs. The car is definitely heavier and does take a little more time to stop. I allow for that in my driving. Eventually it becomes habit, part of the "feel" of driving the EV.

Mr. Whitridge, whose business is finance and investments, has opened Blue Sky Motors here, the first dealership in the southern Connecticut-Westchester County area to market electric vehicles. Blue Sky will sell and service the Desert Lightning, an electric conversion of the Chevrolet S-10 pickup truck manufactured by Eco Electric Corporation of Tucson, Ariz. The electric pickup, powered by 24 6-volt, lead-acid batteries and a direct current motor, has a top speed of about 70 miles an hour, a range of 60 to 80 miles between recharges and a base price of $28,500. Blue Sky is also a licensed assembler, meaning that Eco Electric's prefabricated conversion system can be installed at the dealership. While the Desert Lightning will primarily be sold in quantity to utility companies and government agencies for their service fleets and for use at airports for ground transportation, Eco Electric plans to add a sedan within a year "to satisfy the Greenwich-Westchester market," said Mary Ann Chapman, Eco Electric's chief executive officer ... Recharging systems vary. Some electric vehicles, including the Desert Lightning pickup, have an on-board conductive charging system, sometimes called an "opportunity" or overnight charger, which plugs into a regular 110-volt wall outlet. There are faster, more expensive charging systems that require a 220-volt outlet. General Motors has patented an inductive charge system -- installed at the owner's home -- which transmits alternating magnetic current through a "paddle" inserted into a slot at the front of the car The Desert Lightning charger is included in the price of the vehicle, and each overnight recharge costs $2 to $3. The 220-volt recharger costs about $200 to $300 to install, if a house does not have a heavy-duty outlet, and the charger itself costs $700 to $1,000. G.M.'s recharge system costs even more but is expected to be included in the price of the EV1 ... California's relaxed requirements may have cooled prospects for the small electric vehicle companies that have popped up across the country, but an announcement on Jan. 4 stirred the pot even more: the General Motors Corporation announced it would start selling an electric car, the EV1, in four Western markets this fall. The EV1 is a version of the two-seat Impact electric car, which General Motors began demonstrating in 1990. Built from the ground up rather than as a conversion of an internal-combustion car, the EV1 will have a range of 70 to 90 miles and a mid-$30,000 price. General Motors added that it would bring out a compact electric pickup truck next year ... Mr. Whitridge of Blue Sky is looking at other electric vehicles to add to his dealership and sees no immediate competitive threat in General Motors' announcement. In fact, he said he welcomed the attention EV1 will draw to electric vehicles And Mr. Chezar of the New York Power Authority sees the advent of EV1 as a "very major" step "Although the industry has had a few false starts," he said, "electric vehicles are not going to go away anymore.

Some start-ups already making electric vehicles a reality: * * * Ecoelectric Corp. Tucson "It's good for us that the Big Three are dragging their feet, for it gives the little guys a chance to build up a head of steam," says Mary Ann Chapman. Chapman, a former race-car driver, spent 20 years running her own computer-software business before founding an electric- conversion company, EcoElectric Corp., in 1992. Privately funded with $30,000, EcoElectric does custom conversions of small sedans and pickups; designs and sells EV components; and provides EV consulting, maintenance, and repair services. A self-taught EV expert who drives and races her own peach-colored converted Chevy pickup, Chapman claims she is "not doing anything new and amazing in the R&D category," but rather focusing on workmanship. "My electric vehicles just don't break. Not the way I build them," she boasts. EcoElectric recently entered an alliance with a Phoenix company to launch an electric-vehicle courier service between Phoenix and Tucson, which is scheduled to begin operation next month. It will be the first of its kind in the country, claims Chapman. EcoElectric expects 1994 revenues to be less than $1 million ...

Long before PVs/solar panels and their associated electronics were (ebay) available off-the-shelf like today, the Cornells' house had a solar roof that charged a garage pack made up of PbSO4 batteries too tired for EV use, but still good for storing solar electricity during the day. Both their EVs would charge at night off solar electrons gathered during the day (they're ahead of their time/ahead of the curve). % For EVLN EV-newswire posts use: http://evdl.org/archive/ {brucedp.neocities.org} -- Sent from: http://electric-vehicle-discussion-list.413529.n4.nabble.com/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
