Camcoat improves efficiency of Le Mans cars

Camcoat Performance Coatings, based in Warrington, ceramic coated the exhausts of 20 per cent of the cars entered in the 2009 Le Mans 24-hour race.

Camcoating is the application of three different polymer ceramic materials to exhaust manifolds, pipes and repackable silencers.

A hard, smooth finish is applied internally to provide the first level of thermal insulation and to speed up the exhaust-gas discharge.

A base ceramic is then applied externally with either a satin black or Cermakrome top coating.

Careful preparation of the base metal and individual curing of each thermal barrier coating provide a durable, economic and effective way of reducing the power-sapping heat radiated from the exhaust.

The same coating system was applied to all the V12 Superleague Formula cars prior to the start of the racing series last year.

With the black-finish, race and rally teams have found the exhaust cools so much quicker after engine shut-down that it is possible to touch the exhaust manifold before the cam cover, which can make for quicker and safer repair stops.

Camcoat has been applying these and other motorsport coatings for fifteen years for well-respected component manufacturers such as SS Tube Technologies, Primary Design and Alcon Components and for individual teams and competitors in all sectors and levels of motorsport.
