I tried building an electric turbo that used an RC jet (electric ) engine that produced 8lbs of boost. The current draw was a lot! the only real way I got a performace gain was by running a seperate power supply at the track, not connected to the car, and could only be charged after each run. It was a huge pain and not worth it. It was a cool project since I had the parts laying around, but it is not something that will not last over time. I had it set to spin, and then a clutch would kick in to produce boost when turned on. It was a waste. I even had a friend who is an electrical engineer look at it and say it could not be done to produce a large amount of boost.
