1927 Bugatti Type 35B
The Type 35B marked the introduction of a blower to the Type 35 line. The 35B model was released alongside the Type 39 which was made to correspond with updated Grand Prix regulations.
In 1926 a new rule was imposed limiting engine capacity to 1.5 liters. Bugatti then reduced the bore of the existing Type 35 engine from 60mm to 52mm. To compensate for the displacement, a light Roots type supercharger was added to the engine.This car started an era of blown Bugattis that would last up to the Type 57.
To still perform well in formule libre events such as the Targa Florio, the type 35B was released alongside the Type 39. What made the type 35B distinct was its lager displacement and larger supercharger. The engine was increased to 2.3 liters, having a bore and stroke of 65mm x 100mm.
The layout of the chassis remained generally unchanged from the 1925 Type 35. Brake drum and tyre sizes were increased but it was the blown engine which distinguished the Type 35B from the 35. It is interesting to note that the radiator was more front mounted than previous 35s to make room for the supercharger.
The highlight of the type 35Bs success was had at the 1926 Targa Florio in which the car place first.
