Bohannon B-1

The Bohannon B-1 is a purpose-built aircraft to set new world records in its class for time-to-climb. It is a development of the Van's RV-4.

Development
Bohannon and Miller built the Miller-Bohannon JM-2 Pushy Galore to set the new time to climb records and compete in Formula One air racing. Bohannon continued to set records with his new aircraft. He acquired Exxon as a sponsor for record attempts. His B-1 was painted in a stylized tiger paint scheme and named the "Exxon Flyin' Tiger". The aircraft went on to set 30 altitude and time to climb records.

Design
The Bohannon B-1 is a low-wing, all-metal single-seat aircraft with conventional landing gear. The Lycoming IO-540 engine is augmented with nitrous oxide to increase power from 260 to 425 hp. For 2001 attempts, a Lycoming IO-555 was installed.
