Austin 7 Single Seat Supercharged Works Replica

This is a single-seater Austin 7 built in 2015 as a replica of the supercharged works racers. It is a period-style special rather than an original factory car, and the build is thorough.

The engine was built by Pigsty Racing with a Phoenix crank and rods, a camshaft ground to works drawings, larger inlet valves and Doyle valve springs. A Volumex supercharger feeds it through a large SU carburettor, and a lightened flywheel and heavy-duty clutch are fitted. A four-speed close-ratio gearbox, also from Pigsty, is paired with a new back axle. The car made 70 bhp on the dyno.

The chassis has been strengthened and lightened. Suspension copies the works beam axle layout with a front transverse leaf spring, and the hydraulic brakes use drums machined for a period look. It is painted British Racing Green and sits on 16-inch wheels with Dunlop racing tyres. It has a chassis number and its original log book. It has covered only demonstration miles, including an appearance at the Goodwood Austin Centenary.
