WH Imp

a two-of

Richard Haste and his friend Tony Whitehead used a Hillman Imp to build their own GT, because:

At the time the Hot Car article was written, there was one runner - the white WH Imp in the photos, and the second was being built - it was estimated to be rolling by February 1971. A third was planned: a more spartan lightweight WH Imp, to be used in Hill Climbs and Sprints. Plus they had an intention to market bodies and chassis.

The body is glass fibre. The moulds were formed on a wood and plaster mock-up model. The engine cover is 18 SWG aluminium.

The 5th door lifts (the engine cover and window) to allow access to both the luggage and the engine compartment.

Whitehead - Haste Imp special - front compartment   The radiator is placed up front, along with an electric fan. The radiator is a special cross flow, made by Marston Radiator Services. It uses 1 in. diameter copper piping to carry the coolant from the rear mounted header tank.

Cooling air is taken in through the nose and then ducted out through a slot just in front of the windscreen.
