Racing is a cruel mistress. The heights of achievement can pale in the face of the effort required to succeed, and no form of competition is as fickle—or as seductive—as land speed racing. Instead of simply achieving one’s finest performance on a given day, land speed racing requires competitors to surpass anyone who has ever raced in that class.
Sam Wheeler is a 49-year veteran of racing motorcycle streamliners. He knows first hand the dual-edged nature of land speed racing. In 2006, his 355 mph speed through the timed mile on the Bonneville salt qualified him for the title of World’s Fastest Motorcycle. Only he didn’t know it at that moment. Instead, he was trying to control a streamliner that had lost its front tire just after passing through the timing lights. The ensuing crash meant he was unable to turn the motorcycle around and make the required back-up pass in the opposite direction within the prescribed two-hour time limit, thus forfeiting the championship. (Both Wheeler and the motorcycle were relatively unscathed.)

In 2012, Wheeler was back to once again vie for that title. Since September 2006, Bonneville has hosted a remarkable battle between three streamliners: Dennis Manning and his BUB Seven streamliner; Mike Akatiff’s Ack Attack, featuring twin Hayabusa engines; and Wheeler’s diminutive EZ Hook. In 2006, the title changed hands between Manning and Akatiff over the course of a few days. The three racers have continued to battle for the title since 2006, with Akatiff currently holding the record. But Wheeler is determined to go for the biggest number yet: 400 mph.
The secret to winning this David and Goliath shootout is aerodynamics. The liner’s body shape was developed by four CalTech Master’s students, and yields a slippery 0.1007 drag coefficient. But the small, 3.62 square-foot cross-section of the liner’s nose couldn’t accommodate anything bigger than a skinny 2.5-inch tire. Wheeler’s competitors are running automotive race tires. He’d already shaved excess rubber off the highest speed-rated tire he could find (a 300 mph drag racing tire), bumped its nitrogen pressure to 150 psi, and cooled it with a water spray during the run—with catastrophic results.

Still, the self-taught engineer’s mind wouldn’t rest. Finally, he found a manufacturer to create a solid aluminum front wheel, complete with vintage Avon-style grooves. The next change in Wheeler’s fortunes came from Fred Fox, founder and CEO of Parts Unlimited. Fox had previously sponsored Manning’s efforts, so he understood land speed racing and had the contacts to make things happen. Intrigued by Wheeler’s thoughtful, less-is-more approach, Fox soon penned a sponsorship deal with him. Suddenly, Wheeler found himself with the kind of resources he’d only dreamed of and was back at full throttle, revamping the newly named EZ Hook/Parts Unlimited streamliner.
First came the Goodyear automotive rear tire rated for 450 mph (and costing $1000 each), thanks to Fox’s status as a distributor for Dunlop. Fox’s relationship with Performance Machine assured that those tires had a purpose-built wheel. Next, deals were made for a pair of Hayabusa engines to be built under the supervision of Vance & Hines’ Indianapolis race shop. Long-time supporter Terry Kizer supplied his Mr. Turbo units. Ultimately, these methanol-fueled monsters would produce 500-plus horsepower. The addition of a MoTeC engine control system gave Wheeler many more options for attempting to put the power down on the notoriously slippery salt.
The gearing required to travel at such incredible speeds is so tall that most streamliners can’t leave the start under their own power and must be pushed or towed. However, the rules stipulate that the assisted start take them no faster than 40 mph. Wheeler’s approach instead resembled a drag race. The quicker you leave the line, the more time you have to get up to speed. When everything is going right, the streamliner accelerates through the entire timed mile. Gathering more speed earlier is vital.
