Depending on whether you're used to metric or not, 1001 feet is 305.1 metres and 87 km/h is 54mph (and 1600HP is 1193kW).YouTube
Gudbjørn Grimsson making a world record with the first official speed measured (87 km/h) on a 1001 feet long river in a extreme Formula Offroad race in Iceland! A twin turbo Nelson Racing engine with 1600 HP did the job!
