Today, they talk about volts, amps and kilowatt-hours. One such fellow is Jonny Smith, a Brit who goes by the name CarPervert on Twitter. Jonny was on the hunt for a tiny electric car from the 70’s called the Enfield E8000 ECC. It came from the factory on the Isle of Wight with an 8 horsepower electric motor and a range of about 40 miles using a bank of conventional lead/acid deep discharge batteries. He found the car he wanted in Wales and set about converting it to a drag racer. Smith was determined to make it into a 1000 horsepower 1975 Enfield. His inspiration was John Wayland’s famous White Zombie – a lowly Datsun 1200 that was converted into a ferocious drag racer in Oregon. In an interesting twist, that same car was also the inspiration for the Zombie 222 electric Mustang we wrote about a few weeks ago. Today, the car that started life as a modest electric runabout sports a custom-built battery pack made up of 144 Kokam lithium-ion cells and assembled by British firm Hyperdrive. The batteries are normally used to run the starters and mini-guns in a Bell AH1 SuperCobra attack helicopter. The batteries pack delivers 370 volts, 600 kilowatts, more than 2000 amps, 1003hp, and 1200 lb-ft of torque – all while weighing less than 360 lbs. Those are the kind of numbers that bring tears to the eyes of modern day hot rodders. All that electricity goes to power two 9? Current Racing motors – modified Netgain Warp 9? series wound direct current motors – which turn street legal drag racing tires mounted on massive (for an Enfield) 14×7 Wolfrace mag wheels harvested from a cast-off 1970 Pontiac TransAm. Jonny Smith, aka CarPervert, named his micro-race Flux Capacitor, in honor of the iconic DeLorean featured in the movie Back To The Future. During its first race weekend, his team kept things turned down a bit. After all, 1003 horsepower in a car barely 8 feet long could be a bit scary. “I have to say it felt shockingly good,” says Smith. “The twin 9? Current Racing motors were strong, the coupling and 6? propshaft held, as did the Hyperdrive battery pack, with its twinkling LED lit battery management system.” Later in the weekend, the team turned up the wick and the car sprinted through the quarter mile in 12.56 seconds at 101.43 mph. That’s faster than the original 2010 Tesla Roadster. “Mid 12s makes it faster than any road-going production EV bar Tesla’s P85D – which is my next benchmark to beat,” Jonny said. “That means running 11s.” Can the Flux Capacitor run more than a second quicker? Look at it this way: The Enfield now weighs under 2000 lbs; the Tesla is around 5000 lbs. The Enfield has 1003 horsepower; the Tesla about 700. So far, the Flux Capacitor has been running only 70% of its maximum power. What do you think will happen when all of its full potential is unleashed?

Re: [EVDL] EVLN: UK's 1000hp 1975 Electric Enfield (v)
I thought that torque was calculated/measured at the wheels and to get the highest number, it is typically in 1st gear, so I would not expect that they can break tires loose on a dragstrip if they launch in 4th gear even with a standard diff, let alone with 1:1 diff, because I expect that torque was measured in 1st gear, no? 100 MPH is 44.7 meters per second, with tires that are 24 dia (61cm) the RPM of the wheels is 1400 at 100MPH, you would not want to gear your car to have the motor lugging that low at 100MPH!

Horsepower can also be measured anywhere, and is generally assumed to be at the motor unless it's specified to be at the wheels. Both figures, of course, depend on engine RPM, and peak value is generally specified even though average torque tells you a lot more about what the engine can do than its peak. If it's at the motor, the torque gets multiplied by whatever the final gear ratio is. The ICE half of my Mustang is going to have a 3.89:1 differential, and the engine will put out a relatively constant 400+ ft-lbs between 3000 and 6000 RPM...which works out to about 1600 ft-pounds at the wheels in fourth gear, and nearly 5000 ft-pounds in first -- again, a problem in a ~3000 pound nose-heavy car, but a good problem to have. When I put a dual AC-35 with ~2.5:1 reduction to a front wheel drive axle into the car in the next phase of the project, all-electric mode should be superior to what the original 260 cu. in. V8 was capable of...and hybrid mode is going to be insane, to use Tesla's word. b ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
