JoJo Granatelli
JoJo Granatelli is the third generation of his family to build performance parts, and the one who drives them. He handles Executive Operations at Granatelli Motor Sports in Oxnard, California, and writes the technical articles on this site.
He races what the company sells
On 8 August 2026 at Famoso Dragstrip in McFarland, California, he set a quarter-mile record at Red List Series XXXII: 7.06 seconds at 157 mph. The car was not run flat out. As he put it at the time: "We only ran it through the eighth and then coasted the rest of the quarter, and it still went 7.06 at 157 MPH."
That matters for a reason beyond bragging. Parts that get written about on this site are parts that get used at a track by the person writing about them.
Where the parts come from
Granatelli Motor Sports builds in a 42,000 square foot facility in Oxnard, California, with machining, welding, assembly and dyno testing under one roof. More than 10,000 active part numbers, sold direct and through Summit Racing and JEGS.
The range covers electronic exhaust cutouts, ignition coils and spark plug wires, drive-by-wire throttle bodies, and wastegates and blow-off valves.
Three generations
The racing came first. JoJo's grandfather, Joe Granatelli Sr., debuted at the Indianapolis Motor Speedway in 1946, and in 1949 he and his brothers Vince and Andy opened Grancor in Chicago — a speed shop that machined cylinder heads for American racing cars. Granatelli has been American made ever since. Joe Sr. served as chief mechanic on the Paxton Products Novi Indy cars through 1973, and helped build the 1966–67 Paxton Novi turbine cars that the press called the whoosh mobiles. He held a world land speed record of 198.9 mph in a twin-Paxton-supercharged Studebaker Avanti, and he ran Paxton Products as President and CEO.
JoJo's father, J.R. Granatelli, founded Granatelli Motor Sports as a manufacturer in 1989 and is President and CEO today.
What he writes about here
Every technical article on this site carries his byline. The subjects are the ones customers call about: how to size an exhaust cutout, where to mount one, which ignition coil an engine actually needs, what separates a 44mm wastegate from a 60mm.
The aim is the answer a builder needs before spending money, including the times the honest answer is that a part will not help. Read the articles.
