Here are some photos of rocket-powered funny car. In the builder's words (photos are clicakble):
In the early 80s I built the Pocket Rocket, a hydrogen rocket powered mini funny car. This thing was really tiny, about 8 feet long, just over 30 inches high, and weighing less than 500 lbs.
This thing was seriously scary to drive. It could go 0 to 100 mph in 1 second. 5000 hp weighing 500 lbs, it does not take a rocket scientist to figure out how crazy the power to weight ratio is, so I figured it out and its frickin scary.
