1988-98
IHRA headquarters briefly moved to Waco, Texas in 1988 after it was purchased by Texan racer and track operator Billy Meyer who made many changes to the organization, some of which proved controversial amongst racers such as completely restructuring the sportsman classes overnight. Another radical change came as a result of Meyer's ownership of the Texas Motorplex, considered then to be the premier drag racing facility in the world. The Motorplex had previously been the NHRA's flagship track but for 1988 it hosted two IHRA national events and was the site of Top Fuel's first 4 second run by Eddie Hill. Other changes included the addition of a 'junior' Pro Stock class for small-block and V6 engines, named Factory Modified, which lasted until the end of the 1990 season. However, financial failure meant that Meyer's reign lasted just one year before the association was again sold on.
In 1990 an all new class, Pro Modified, was introduced which has since become a feature at IHRA events and has become one of drag racing’s most successful classes enjoying popularity in both North America and Europe. During this period Pro Modified became the IHRA's main asset in its recovery from the 1988 season that had nearly destroyed it.
However, the nitromethane powered Funny Car class was dropped for the 1991 season only the be reinstated for 1992 before being dropped again, not to return until 2006. In 2009 IHRA dropped the funny car class again due to sponsor problems caused by a deep recession in the American economy.
