MG has a famous history with supercharged sports cars, particularly in the pre-war era. This post war 1971 supercharged MG BGT started life with a standard 1800cc unit. It was built as the sister and tow car to a MG BGT V8 Sebring recreation.

The engine and gearbox were removed and the engine bay sandblasted then sprayed metallic dark British Racing Green. The engine was rebuilt with a gas-flowed head and the pistons replaced for ones suitable for supercharging. A NOS (new old stock) Shorrock 142B supercharger kit was fitted along with a LCB manifold and big bore exhaust. The gearbox was replaced with an overdrive version. The car was then test driven to check setup. She was then stripped out, the suspension overhauled and up-rated Spax adjustable shock absorbers fitted to the rear with new springs, front shock absorbers and anti-roll bars to the front. Minimal rust was found to the body shell; however, what was found was removed and the necessary high quality repairs undertaken. The bumpers were removed and a steel Sebring front valance was fabricated as well as a fibreglass Sebring rear panel to further improve the looks. An MGC fibreglass bonnet was added to clear the supercharger's carburettor. The car was then shipped to Faircharm Restorations for preparation and re-sprayed in metallic dark British Racing Green. In addition, a dual point Mallory distributor was fitted to enable an accurate timing curve for the supercharger to be set.

In 2013 the vendor spent a further £2,500 carrying out improvements, this included a full service, wiring repairs to the front wiring loom, new oil pressure/water temperature gauges as well as new rear number plate lights and new number plates. A horn was supplied and fitted together with a new indicator/horn/dip switch. The brakes were up rated with MG Owners Club front callipers, brake pads and grooved brake discs together with a new brake master cylinder and the overdrive solenoid was replaced. New seat belts were fitted along with new door mirrors and a new MGOC exhaust system. Finally, earlier this year, four new Avon tyres were added and a MoT test certificate obtained which expires on the 24th April, 2015.

The file accompanying this car has receipts for items purchased including the receipt for the Shorrock Supercharger from Alf Hagon of London, a detailed build book as well as the UK registration document. When one considers the specification and works carried out, this supercharged MG represents excellent value and huge fun in classic form.
