Street demon™ carburetorS

Looking for something even more hi-tech than the Street Demon™ aluminum carburetor? The Street Demon carburetor with Aerospace Composite fuel bowl incorporates the latest technology designed to combat the problems with today’s challenging fuel chemistry. By incorporating a composite fuel bowl, heat transfer from the intake manifold and hot under-hood temperatures to the fuel are minimized, resulting in fuel temperatures up to 20 degrees less than conventional two piece carburetors. By keeping the fuel cool, the engine makes more power, idles better and starts quicker. The unique one piece fuel bowl is made utilizing the latest in materials technology and is highly chemical resistant, ideal for today’s corrosive fuel additives. Don’t settle for the competition’s dated design or spend a fortune on the latest EFI fad, demand Demon for “PERFORManCE tHat’s Out OF tHIs HIs WORLD!”

Power Valves Proper power valve selection is crucial to carburetor tuning Demon Fuel Systems offers a complete range of quality power valves to accommodate every tuning requirement. Our power valves are rated in inches of mercury (amount of vacuum) required to open the valve. Most 4150/4160/2300 model carburetors use the Standard while 4500 and alcohol carburetors use the Hi–Flow power valve. Power valves should be replaced periodically to prevent leakage. All include gasket. Part# 240025 240035 240045 240050 240055 240065 240075 240085 240095
