It's a funny thing.
The first time I went to Bonneville, in 1989, I got to 'know' the Nafzger/Savage, four-wheeled LSR, Ninja-powered streamliner, owned, designed, and driven by Howard Nafzger, a retired IBM engineer, along with his partner in crime, Mr. Savage.
The motorcycle engine was essentially 'bone-stock', which was a surprise to me.
As the 'new guy' it never occurred to me that these cars were running flat-out for 8-miles, and the demands that would place on a powerplant.
Winning a speed record could be a matter of just holding an engine together long enough to quality, and then after impoundment, do the return run, a requirement for an official, two-way averaged FIA speed/ time.
Everyone returned the next year. ESPN was there to film the whole thing, and Howard pulled off an average 247-mph, for a Red Hat and a 1-liter speed record.
