New Street Demon Carb Install and Adjustment


Before the new Street Demons were first released to the public on Friday, May 25, 2012, the carburetor company dispatched twenty to thirty pre-production units to discerning carburetor critics for testing and evaluating. For this purpose Street Demons were sent all over the country—even to Australia.

Tests were conducted at sea level and in the mountains, in cold and in hot conditions, in stop-go traffic and in engines with unfathomable camshaft timing—profiles contrived for noise rather than power. Some even found their way onto tow vehicles, lugging heavy trailers up hills. All testers were invited to “Have at it,” as they say and were actively encouraged to present their findings—warts and all.

One of these pre-production Street Demons appeared at Automotive Service and Performance (ASAP), a hot rod tuning shop in Gainesville, Georgia. Known as the poultry capital of the world, Gainesville nestles in the Appalachian foothills on the shores of Lake Lanier about 50 miles north of Atlanta. It has an elevation of 1250 feet.

TOP: Demon Carburetion’s decision to conduct 20 to 30 independent pre-production carburetor tests led Tommy Haley of the ASAP hot rod shop to conclude, “This carburetor is apt to be good.” And car owner Rick Ellis says, “The Street Demon surprised me twice: it has superior performance and my fuel consumption improved!”

MIDDLE: Bobby Tow of ASAP anticipates much potential from the first Street Demon in town.

BOTTOM: This 1972 Dodge Dart is mostly original except for the addition of power disc brakes, Mopar Performance valve covers and air cleaner, the Edelbrock 600 carburetor with vacuum secondary throttles and electric choke, and aftermarket headers and dual exhausts.
