This Unlimited racer evolved as a direct result of John Sandberg and Bruce Boland. Both had been involved in the world’s fastest motor sport for the last 25 years, Boland as a design aerodynamicist with Lockheed’s advanced projects’ engineering department, and Sandberg as a powerplant specialist and accomplished pilot. His engine shop, JRS Enterprises, rebuilds Merlin and Allison inline engines for warbirds, though its speciality is the larger radial powerplants. When discussions began on the design and construction of a custom-built Unlimited in the early 1970s, a lightweight, Allison-powered racer was envisaged. However, as the project evolved and both men put their considerable input into the design, a slightly larger and racey-looking Merlin-powered aeroplane emerged.
Tsunami first flew in 1986.
