New 625 Street Carburetor Makes Debut
New Carburetor Engineered for Hot Rods with Stock to Mildly Modified Engines
The introduction of an
all-new carburetor, especially in this millennium, has become increasingly
rare. But Demon Carburetion has done just that. Named the 625 Street Demon, it
is engineered for hot rods with stock to mildly modified engines.
In appearance, its cast aluminum
construction exhibits smooth and flowing contours and in operation it
accommodates either square- or spread-bore-pattern intake manifolds without
adapters. It’s an easy replacement for any street four-barrel.
Developed from clean-sheet beginnings, the
Street Demon features two potent
1-3/8˝
primary throttle bores, which contain triple-stack boost venturii. Two of the
boosters are suspended across the bores in the conventional way; the third is
neatly integrated into the throttle bore walls. Their purpose is calculated to
produce superior fuel emulsification, to present crisp throttle response and
drivability, and to provide pleasing fuel economy.
At the top of the secondary bores a torsion
spring-controlled air valve resides. Its function is to ensure seamless
primary-to-secondary throttle response, regardless of the throttle opening
rate. Its two distinctive, sloping contours are engineered for efficient
cylinder-to-cylinder fuel distribution. Torsion spring adjustment of the valve
is controlled by a screw on the end of its shaft axis.
At the bottom of the secondary bores a
goggle valve (GVS™) resides. This innovative device delivers over twice the air
flow of the primary bores, with an effect that can be both felt and heard.
The Street Demon’s fuel bowl, which is
integrated with the main body, is available in either aluminum or an exclusive
automotive-spec polymer. The polymer bowl demonstrates impressive hot-weather
drivability and faster hot restarts by reducing heat transfer to the fuel by as
much as 20 degrees Fahrenheit. To eliminate all potential leaks the bowl is devoid
of plugged passages and the bowl gasket is placed above the fuel level.
A single fuel inlet ensures simple
installation and two-stage metering rods accommodate most tuning requirements,
without carburetor disassembly or removal. For cold starting, a proven electric-assist bimetal coil choke is provided.
Street Demons are available in three forms:
all aluminum tumble-burnished, tumble-burnished with polymer fuel bowl, and all
aluminum hand polished. Prices are $349.99, $379.99 and $449.99 respectively.
