Bowling Green KY: 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 1-3/8in 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 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.

Dahlonega, GA: Demon Carburetion has introduced 6 new and improved four-barrel carburetors in the following sizes: 650, 750, and 850. Known as Speed Demons, each size is available in two forms: three are equipped with mechanically operated secondary throttle plates; the remaining three with vacuum-operated secondaries.

Vacuum-operated secondary throttle plates are ideally suited to engines with automatic transmissions lacking high-speed stall converters. Alternatively, carburetors with mechanical secondaries are preferable for vehicles with manual transmissions or automatics with higher stall-speed converters, operating at 2,500 to 2,800rpm. Vacuum-secondary Speed Demons are instantly recognizable by the red billet aluminum cap on the vacuum pod.

Speed Demons are classified as general performance entry-level downdraft carburetors. Featuring down-leg boost venturii, they replace most standard square-flange carburetors on engines with camshaft durations of up to 240 degrees @ .050in of valve opening. The 650 model performs at its best on mildly tuned engines with displacements of 302 to 427cu in. The larger 750 Speed Demon works exceptionally well on 393 to 477cid engines and excels on mildly tuned engines from 427 to 455cu in. The largest carburetor of this new Speed Demon range, the 850, is particularly well-suited for operation on big-block crate motors, ranging in displacements from 488 to 540cu in.

Renaissance Man

Demon is enjoying a blessed renaissance via its sales manager, Scott Witmer, the affable 44-year-old Marylander. Witmer oversaw much of the company’s incredible rise to fame in the late 90s, beginning with the Claw-a successful high performance carburetor which dominated and led the way for the Demon range.

He opens the subject by saying, “Today’s new Demon carburetors are produced to much tighter quality requirements (ISO 9001:2008) than previous. Our new production standards instill the kind of confidence I always dreamed of. And, I’m enjoying being part of the revival and of Demon’s new credentials.”

Nine months ago it was almost inconceivable that the Speed Demon, or any of the renowned range of carburetors, would re-emerge following the company’s closure on February 18, 2011. But happily six months later a group of enthusiastic professionals purchased its operating assets, resurrected its production lines, introduced strict production standards, and brought it back to life.

Columbia, SC: Ram Clutches has introduced two new metallic clutch alignment tools for 26-spline GM and Ford applications. Machined from 1040 plain-carbon steel and each with a spline diameter of 1.125in, one alignment tool features a pilot bearing tip to suit GM applications (PN 03-013), the other Ford (PN 03-048).

While plastic clutch alignment tools have been invaluable in clutch installations, they are not always exact. Ram’s new metallic device is a professional tool that ensures accuracy. In addition, it is especially useful in centering dual-disc assemblies. Because its long shaft diameter is smaller than its splined diameter, this device allows you the convenience of installing the flywheel on the engine, slipping the alignment tool into the pilot bearing and sliding the discs onto the tool one at a time with the floater plate sandwiched between.

Providing perfect alignment, these new tools are priced at $64.99 and are now available from Ram and their distributors.
