The Blower Continued Series, which Bentley announced last year and launched within the framework of its 100th anniversary celebrations, has taken an important step. The digital modeling of the 4.398-series sequel of the supercharged 12 cc 'Team Blower', designed by Sir Tim Birkin and used in races, has been completed. Working from home during the pandemic period, the Bentley team created a digital model for the production of new parts of the cars in the series, using laser scanning and precision measurement methods. The series, which will be created with the work of Bentley Mulliner's Classic Cars section, will form the world's first pre-war racing car sequel.

The new owners of these 12 models, which have already been sold, are still at the stage of determining the color and design options of their vehicles.

An important step was taken in the Blower Continuation Project, which Bentley announced last year and planned to carry out within the framework of the 100th Anniversary celebrations: the digital CAD (Computer Aided Design) model, which will be the main design and engineering reference for new cars, has been completed.

In addition to being a complete mechanical copy of the 12 Team Blower designed by Sir Tim Birkin and used in races, each of the cars in the series, which will feature 1929 new Bentley Blower, will probably be the most valuable Bentley cars in the world today.

The cars in the sequel are produced by a special team working in the Classic cars section of Bentley Mulliner. The team, which has gained experience with the recently restored 1939 Bentley Corniche, is currently working with a team of classic car experts to redesign and manufacture the parts needed to bring this new car series to life.

They worked an average of 1200 hours at home

After Bentley's Team Blower car was disassembled, it was reassembled digitally. For this purpose, using the laser scanning and measurement methods, the team created the last CAD model consisting of 70 components in 630 groups with a total size of more than 2 GB.

It took 19 man-hours of two private CAD engineers working from their homes due to the COVID-1200 crisis to make the model ready from start to finish, using scan data and measurements. The result is the first accurate and complete digital model of a Bentley car built in the 1920s.

In addition to helping with the design and development of the CAD model, it also helped design the cars of individual customers. Bentley Design team was able to create accurate and full-color images based on data.

All 12 models are already sold

The cars in the Continuation Series will be mechanically identical to Team Blower. Each of these 12 new cars has already been sold to classic car collectors around the world. Owners of the new models are currently in the process of choosing their own exterior and interior color palettes and materials. Thus, the cars in the new series will be visually separated from their predecessors.

Team Blower Cars

Only four original 'Team Blower' cars were produced by Birkin in the late 1920s to participate in the races. Each of these cars appeared on the tracks in Europe. Team UU 5872, the No. 2 Team Car, used by Birkin himself, the most famous car in the series, competed in Le Mans and played an important role in the victory of the Bentley Speed ​​Six in 1930. The Team Blower car with frame number HB 3404, which is the basis for the Continuation Series and belongs to Bentley itself, is that car.

In addition to the original molds, tools and a range of traditional hand tools from the 1920s, 12 sets of parts are produced using the latest manufacturing technology, and then the talented classic car technicians of Bentley Mulliner assemble the new Blowers. Bentley's original Team Blower Car will be reassembled later. At this stage, the classic car team will carry out a detailed investigation, if necessary, undertaking a discreet and conservative mechanical restoration, and will make the car original in 1929.

Today, the 90-year-old car still roaming the roads regularly completed the 2019 Mille Miglia race, the climbing stages of the Goodwood Speed ​​Festival and a short tour on the California coast, including a parade in Laguna Seca. He also appeared at the 2019 Pebble Beach Concours d'Elegance with two of the other three Team Blower cars.

Each of the cars in the new Continuation Series, a successor to the original Team Blower, will feature four-cylinder, 16-valve engines, as well as an aluminum crankcase with cast iron cylinder liners and a non-removable, cast-iron cylinder head. The supercharger is a replica of the Amherst Villiers Mk IV root type supercharger. Allows the 4398 cc engine to produce 4.200 bhp at 240 rpm. Car; Bentley & Draper will feature replicas of shock absorbers, semi-elliptical leaf spring suspension and a pressed steel chassis. Bentley-Perrot 40 cm (17.75 ”) mechanical drum brakes and reconstructed versions of the sectored steering pattern with worm gear will complete the chassis.
