During World War II, faced with shortages of fuel for civilian use, Bandini adapted his automobile engines to operate with wood gas.

After constructing a second example,[clarification needed] Bandini entered the 1949 Mille Miglia with his new 1100 siluro, featuring torpedo-like bodywork and cycle fenders (separate mudguards).

Here, in the hands of drivers Dick Gent and Bob Said, the car gained early racing successes: its lightness and stability, using a patented elliptical-section steel tube space frame, were particularly appreciated.

From 1953, the bodywork was produced in-house,[citation needed] Meanwhile, the Crosley-sourced engines underwent a radical transformation: a new gear-driven DOHC head was fitted and a single Weber carburetor replaced the Dell'Orto.

Entered in the Mille Miglia, the 750 proved the World Sportscar Championship result at Sebring had been no fluke, but failed to finish in Forlì.

Nevertheless, it was consistently placed in the top three at Salerno, Ascoli Piceno, Teramo, Macerata, Senigallia, Montenero Circuit, and the Consuma (Bologna) hillclimb, which concluded a successful fourth year in the Italian 750 cc championship.

In 1954, production of the two seat sport torpedo continued alongside the new single seater Formula 3 car, for which an impressive 93 hp (69 kW) at 9,000 rpm was claimed.

In 1955, Dave Michaels competing with his 1,625 cc (99.2 cu in)[citation needed] Bandini-Offenhauser won the 2000 cc E Modified (EM) class at Watkins, contesting on equal terms with Monzas, Maseratis, Cunninghams, and Mondials of greater engine capacity, establishing a Thompson track record by two-tenths of a second that would remain unbeaten for a year and a half.

Dolph Vilardi won the 750 cc H Modified (HM) class in the US Championship with 6,000 points, beating Crosleys, Renaults, Giaurs, Panhards, Siatas, and Nardis, among other specials.

The next year saw Bandini wins by Rudkin at Berverly, Yares at Watkins, Michaels at Thompson (FM and time trial) and Bob Major at Bryanfan.

Also in 1956, a 750 sport siluro fitted with a David Uihlein-tuned 1250 cc MG engine, achieved two wins, two second places, a fourth, and only one retirement during the entire season.

[citation needed] In 1957, Bandinis dominated the 750 cc H Modified (HM) category: Melvin Sachs earned an SCCA title winning 3,600 points in the class; Rudkin (who had switched to Saab power for the season) ended the year second, with 3,200; Gordon Wright was sixth with 1,800: seventh was George Tipsword on 1,400; and Jack Connoly finished tenth in the points chase with 1,000.

At Predappio, Bandini won outright in 1955 and again in 1956, in which year the team came in third overall, achieving a class win at Bologna S. Luca, third place at Consuma, a win at Compiano Vetto d'Enza and another first place at the Emilia-Romagna Automobile Club championship held at the Modena aeroautodrome, a unique development (now derelict) constructed in 1949, and combining the functions of a small commercial airfield with those of a test track for the locally based manufacturers of sports cars.

Garvini and Camisotti-Sintoni put in outstanding performances in the Mille Miglia, while Illario Bandini himself won the Bologna-S.Luca and achieved a seventh place in the inaugural event at Vallelunga.

Eichenlaub also managed a third place at Watkins Glen and at Virginia, while Gene Parsons won at Miami (Florida) and again at Washington in the Congressional Cup.

The team finished 1957 ranked second in the overall US classifications, having held the top spot until September when they were unable to participate at Watkins Glen following a retirement at the Virginia circuit.

For 1959, Bandini achieved class victories at Compiano Vetto d'Enza (third overall), Trapani-Mount Erice, Predappio-Rocca delle Camminate, a second place at Trento-Bondone, a third at Vallelunga, and fourth in the St. Ambreus Cup (at the Monza high speed oval circuit).

Very belatedly (seeing Coopers had been offering mid-engined racers for sale since 1946),[1] the Bandini Formula Junior used a rear-mounted Fiat engine, tilted 15° from upright.

In 1960, Ilario Bandini was invited to Daytona, where the Racemaster team took part in the famous sports car event with a ‘'Saponetta'’ and a Zagato-bodied Berlinetta, driven by Luckens, Richardson, and Callanan.

Meanwhile, in the same year back in Italy Bandini were active in the 750, 850 and 1000 classes using Banidini DOHC front and rear engined Formnula Junior, 1000P and Saponetta models.

As Bandini himself reached fifty years of age, he continued to race, including at Sassi-Superga, Aosta-Pila (second), Vergato-Cereglio, and Cesenatico.

Bandini himself had little luck in the Four Hours of Pescara (valid for the World Sports Car Championship), co-driving with Alberto Canali, but saw Cecchini and Cesare Sangiorgi classified sixth.

Benelli was third in the Cuneo (Garessio-hill St. Bernard), the Cup of Cimino (in Rome), according to Teramo and Bolzano-Mendola, while finishing ninth at Vallelunga, and retiring for breach of the exchange at the Targa Florio.

In 1965, a version of the 1000P (unusually, Belgian racing yellow) gave Benelli a win at the Predappio hillclimb and the first Castione Baratti (Parma) then runs Paganelli with the Trento-Bondone Cesana and Sestriere.

Despite engines enlarged to 850 cc, and remaining unbeaten from 1961 until 1963 in SCCA's South-West Division championship (led by Hugh Grammar and T. Hotchkiss, who in latter years won in F. Junior at Sebring), in the mid-1960s, production for the United States was stopped for lack of adequate funding, radical changes of regulations, unfunded riscuotibili, and competition from large manufacturers.

At the whip of Dolcetti, Ghini, Benelli, Gatta, Ferrucci, recent prototypes have won the Cup Water Cerelia, Camucia-Cortona, the Colle S. Bartolo (PU), the Gubbio-Madonna della Cima, the Cup of Chianti (half kilo of underweight) and seized countless placements: Trieste-Opicina, Bologna-Raticosa, Ascoli-hill St. Marco, Castione Passo della Presolana, circuit of Mugello, Targa Florio, Magione and many other races (predominantly hillclimbs) throughout the country.

The company in 1980 presented the 1300 with 16 valves, mechanical fuel injection, and electronic ignition; after chassis, engines and flying, now also looking alloy wheels are facts and carry the signature Bandini.
