Cayenne, then released so he went through the timing gate under his own power. He was timed at
174.33mph after going through the 200-metre speed trap on the machine, built by Moss Bikes using 3D
printed components and parts from a motocross bike. The Porsche had a large attachment on the rear,
which affected its aerodynamics, punching a hole through the air for Mr Campbell to cycle in.
He said: “I am thrilled and relieved, the team worked amazingly well.”
Preparations had gone badly with poor weather on Friday. A practice run fell 20mph short of the record, but
conditions improved on the day and a tailwind helped. Changing the aerodynamics of the car was a balance,
as it decreased the 4x4’s top speed, but reduced wind resistance when the bike was released.
Mr Campbell laughed: “Porsche spend millions testing their cars in a wind tunnel and we stick a big
Tupperware box on the back of it!”
He was so desperate to break the record that he ditched a parachute designed to help him brake quickly
before the end of the airfield – because it was causing turbulence. But he did wear the latest kangaroo-skin
protective suit, which inflates in the event of a crash.
His next challenge will be to try to reach 220mph next year on a six-mile track at the Bonneville Salt Flats in
Utah, USA.
He said: “This has been a five-year programme and the record was the culmination of one part of it. We
have been bound by finances and budgeted to do what we can. Our plan is now to go to Bonneville and use a
longer test track.”
