1991 Intrepid RM-1

Jim Miller of the famous Pratt & Miller commissioned and built the Intrepid RM-1 for the 1991 IMSA GTP season.

The design was entrusted to Riley Technologies were Bob Riley and his son sketched a GTP model that had as much downforce as possible.

Pratt & Miller handled construction of the RM-1 and Chevrolet offered an 800 bhp version of Katech-built small-block V8.

Fielded by MTI and Tom Milner Racing the RM-1s had a steady streak of finishes with occasional podium finishes including 1st overall at the 1991 Hours of New Orleans as the only victory.

As the RM-1 was built with incredible levels of downforce, it was more suited for the smaller tracks and not large endurance tracks like Daytona.

Momentum for the RM-1 project fell when Tommy Kendall’s rear suspension failed at Watkins Glen sending him into the wall at 140 mph which nearly ended his career.
