To put the performance of Studebaker's 289 V8 in perspective, the Ford 289 V8, as used in the 1965–1967 Mustangs, produced 210 horsepower with a two-barrel carburetor, 220 horsepower with a four-barrel carburetor, and 271 horsepower in Ford's high-compression, solid-lifter, four-barrel "K-code" engine. Thus, Studebaker's "Jet Thrust" 289 V8s were significantly more powerful than any 289 production engine offered by Ford through 1967 (in 1968, Ford began relying on the new 302 cubic-inch engine).
Studebaker had first used Paxton superchargers on the 1957 and '58 Studebaker and Packard Hawks. Subsequently, they bought the company. With the assistance of car racing legend Andy Granatelli, Studebaker developed an R-3 engine for the Avanti. The first was a 289 was bored initially to 299. Later versions were 304.5 cubic inches (just under the class-C five-liter limit). The R-3 employed special cylinder heads with much larger intake ports and larger valves, an aluminum intake manifold with correspondingly larger ports, long-branch lower restriction exhaust manifolds, a higher-lift, longer-duration camshaft, and a Paxton supercharger blowing through a Carter AFB four-barrel carburetor mounted in a pressurized aluminum box. The R-3 was rated at 335 horsepower, but reportedly produced 400 at the flywheel!
During the summer and fall of 1962, Granatelli took several Studebakers to the Bonneville Salt Flats, including an R-3 Avanti in which he reached a record speed of 170.78 mph. By the time he was done, Granatelli had set or broken 34 U.S. land speed records in the Avanti, allowing Studebaker to proudly proclaim it the "World's Fastest Production Car". In addition to being fast, the Avanti led the domestic auto industry in the use of front caliper disc brakes (Dunlop discs produced under license by the Bendix Corporation).
