At 5.5bar boost, the BMW Turbo was rumoured to produce in excess of 1350bhp in qualifying and said to race somewhere north of 1000bhp.

Horsepower was unlimited, you could run as much as you could wring out of 1.5 litres. The ’86 cars remain the most powerful ever to race. Mike Tyson took just two rounds to become the youngest ever Heavyweight World Champion and the first F1 Turbo era reached its peak.
