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.
