"We just cut the car down the middle and widened it, so now it looks like a go-kart," Wong told Discovery News. "It's very wide, so it didn't tip over like some of the other teams. There are double wheels in the back for traction."
At the previous day's races, Wong's team started off using a truck starter engine, the kind responsible for holding the the world record for electric bar stool speed at 55.9 miles per hour. "It goes really fast, but it didn't work out too well," Wong said. "Yesterday's motor burnt up the speed flex rotor. We had to swap engines with a Little Tikes car, which lit on fire."
While Wong is unsure about how fast her souped-up Ferrari can go, she said her team pulled an actual motor engine off another scooter and it's powered by two car batteries.
"Those are Optima batteries," Wong said. "We're actually sponsored by ChumpCar, which provides us with batteries."

Wong's team takes their name from Oakland's DIY hacker/maker space, NIMBY, billing itself as "the largest do-it-yourself industrial art space in the Bay Area," boasting over 40 different art groups and craftsmen in the shop. Check out more photos of Wong's car being built at NIMBY headquarters here.
