Petersen 4.5 Litre Blower

The Petersen 4.5 litre Blower is an authentic recreation of the charismatic 'blowers' developed for racing by Sir Henry Birkin and his team in the late 1920s.

 

Acceleration and performance at speed are breathtaking. With the powerful whine of the supercharger to complement the raucous exhaust, a stunning 'entrance' to any event is guaranteed.

Many of the fittings are made by us: filler caps, stone guards, footplates, fuel tanks, radiators, wheels, hubs, superchargers, bodies, trim, dashboards as well as many other smaller parts.
