Granatelli Motor Sports, Inc. was founded in 1989 by the charismatic and always outgoing J.R. Granatelli. J.R. is a consummate businessman, inventor, project vehicle builder, published author and licensed Pro Stock racing driver who holds the current world record for the fastest modular engined Mustang.

Performance heritage is truly an understatement as his family, with over 70 years in the business and 3 generations of performance minded gearheads, has set over 300 land speed records, several Indianapolis 500 wins (including 1969 with driver Mario Andretti), and the legendary performance of the Paxton Supercharger to their credit.
