The credit for this outstandingly practical Halon solution goes to a Ford GT owner who happens to be a retired Fire Captain who has seen numerous car fires during his career. The National Fire Protection Association (NFPA) estimates that an average of 325,100 were reported annually in the U.S. in 1993-2003. NFPA reports that more than two-thirds of the fires began in the engine, running gear, or wheel area. It stands to reason that high-performance automobiles such as the Ford GT re more vulnerable. Exotic sports cars, in general, run higher HP levels and compact engine compartments that are often subjected to intense heat. This fact combined with complex fuel injection systems - such as the Ford GT's where 16 separate fuel injectors are utilized where typical V6 and V8 automobiles use 6 and 8 injectors respectively. The Cool Tech / Safecraft Halon 1211 fire suppression system has been designed exclusively for the Ford GT. A dual function detector/sprayer is strategically located above each bank of fuel injectors. The system recommended by Cool Tech LLC, uses a full 4lbs of Halon 1211. The system is fully automatic and draws no battery power though it is armed and "guarding" against fire 24 hrs a day, 7 days a week. Installation is very straightforward as the components and mounting have been engineered for the GT. Of course, like all Cool Tech GT products, no cutting or drilling of the GT is ever needed.
