Quick Fuel Technology® Introduces Three New 450cfm 4V Carburetors

BOWLING GREEN, KY – Throttle response can be more important than peak horsepower, especially for most street vehicles, and nothing affects throttle response more than carburetor size. Prior to Quick Fuel Technology’s® (QFT’s) new 450cfm four-barrel carbs, folks with small V8s and 4- and 6-cylinder engines had to work with 600cfm or 650cfm carbs. Regardless of calibration, airflow and fuel curves were rarely optimal.

QFT has solved this dilemma with three new 450cfm models centered around a single die-cast aluminum main body with 1.090” venturis and 1-9/16” throttle plates. There is a mechanical secondary HR-Series, a polished vacuum secondary Slayer model and a Black Diamond® version of the Slayer. These carbs feature normal 4150 modular carb dimensions such as air-horn diameter and baseplate bolt pattern – so they bolt to 4150-flanged intake manifolds and accept traditional four-barrel air cleaners.

QFT’s HR-450 model shows its true performance heritage with mechanical secondaries, dual metering blocks and dual-inlet fuel bowls. The only visible concession to daily street driving is the electric choke. Enthusiasts are already sizing up these carbs as ideal for small-block street tunnel rams. Install the 1:1 Quick-Link™ secondary link for cruise night antics, then swap back to the 40% link for more economical daily driving.

The Slayer SL-450-VS and BD-450-VS offer all of the adjustability of the original Slayer carb and feature the single-inlet, side-hung fuel bowls that make them so adaptable to early muscle cars and O.E. replacements. They both have vacuum secondaries with QFT’s Quick-Set™ single screw adjustment and electric chokes. They are completely adjustable with changeable air bleeds and primary and secondary main jets. The Black Diamond® version lowers fuel temperatures by up to 6% and is scratch and corrosion resistant.

Quick Fuel Technology® Introduces New 2-BBL Circle Track Carburetors

BOWLING GREEN, KY – Quick Fuel Technology® (QFT™) has introduced a new series of circle track racing 2-BBL carburetors (Part # XP-4412) that are packed with features designed to make them competitive with the one-off custom-built carbs that cost hundreds of dollars more. Precise, black anodized billet metering blocks and throttle bodies are devoid of casting flaws and irregularities. A die-cast, lightweight aluminum main body has centered venturis for improved performance and better distribution. The choke tower has been eliminated and the inlet specially contoured for increased airflow as well. An anti-siphon check valve is installed in the main body to reduce pump pullover. The throttle body incorporates roller bearing seals that provide for smoother operation and less wear on the shaft. Specially designed straight leg boosters provide higher airflow (XP-4412-S only).

Like all QFT carbs, these new 2-BBL Circle Track Carburetors are infinitely tuneable with changeable air bleeds, emulsion bleeds and power valve channel restrictions. They are augmented with adjustable idle mixture screws. For those exacting and difficult race applications optional 3-circuit metering is also available. Rounding out the fuel handling duties is a dual inlet fuel bowl with -8 AN fittings. It is equipped with dual sight glass windows for easy float adjustment and a single wedge style circle track float.

QFT finished off these carbs with its proprietary Black Diamond® coating that provides enhanced corrosion protection and a 6% reduction in fuel temperature. Quick Fuel’s 2-BBL Circle Track Carbs are available for use with gas, methanol and E85 fuels. There are currently four carbs available – three 500cfm models with 1.375” venturis that are intended for classes with a “gage rule”. Part # XP-4412 is for gas, part # XP-4412-A is for methanol and part # XP-4412-E85 is for ethanol and E85 fuels. Part # XP-4412-S is a Sportsman version that flows more than 600cfm with a 1.450” venturi and is calibrated for gas.

Quick Fuel Technology® Introduces New Quick Cool Carburetor Insulator Kits

BOWLING GREEN, KY – Many carburetor problems can be traced to elevated fuel temperatures in the carburetor. Vapor lock, erratic idle and unresponsiveness to adjustments are just a few of the typical issues. That’s why Quick Fuel Technology® (QFT) developed its Black Diamond™ heat resistant coatings for its carburetors and manifolds. For those without coatings, QFT’s new Quick Cool carb insulator kits (Part # 300-4013) reduce heat transfer to the carburetor by both deflecting heat away from the carb main body and fuel bowl area plus reducing heat transfer from the manifold flange to the carb base.

QFT’s Quick Cool Insulator Kits are a thin aluminum and poly-core sandwich that fits between the carburetor and manifold. It is designed for 4150-style carb flanges and fits Holley®, QFT™ and Street Demon carbs. The bottom layer of aluminum deflects some of the heat around the insulator. The poly-core reduces the heat transfer and the top layer is designed to dissipate any heat that might get through.

The kit comes complete with the poly-core sandwich insulator, non-stick open flange gaskets, carb studs and hardware.

Quick Fuel Technology® Introduces Revolutionary Electronic Fuel Injection System

BOWLING GREEN, KY – Quick Fuel Technology®, known for its innovative carburetors and fuel systems, is introducing QFI – a bolt-on throttle body electronic fuel injection system capable of supporting 500 horsepower. While the market is awash with bolt-on EFI systems, QFI is different: It combines the superior fuel atomization aspects of a carburetor with the precise fuel control of EFI. The patent pending 8-hole annular discharge sleeves inject fuel into a venturi where air speed is at its peak, and pressure is at its lowest, atomizing the fuel far better than any traditional injector nozzle can do. This results in a much more homogeneous fuel/air mixture that burns faster and more complete, producing more power and better response.

QFI not only has superior fuel delivery, it is packed with features like an on-board ignition driver (no spark box necessary), and full timing control with an integral two-step rev control. The QFI fuel injection system has versatile programming solutions including self-learning capability, hand-held controller or laptop tuning if desired.

Quick Fuel’s QFI is designed for 4150 and 4500 style flange intake manifolds, and fuel delivery is provided by 62 lb./hr. injectors. It is compatible with power adders such as nitrous oxide, superchargers and turbochargers, and with minor modifications, can be used with E85 fuel.

OEM sensors are used for easy replacement if necessary. QFI is available in two finishes – QFT’s exclusive Black Diamond™ black satin finish, or polished aluminum. The QFI system is available as a Base Kit or Master Kit that includes an in-line fuel pump and fittings.

Quick Fuel Technology™ Adds 600cfm Carb to Its Black Diamond™Series

BOWLING GREEN, KY – Quick Fuel Technology™ (QFT™) produces several versions of 600 cfm performance carbs from the Hot Rod Series to the affordable Slayer™ Series. However, none of QFT’s current carburetors address the direct replacement requirements, including a single fuel inlet and side-hung fuel bowls. Quick Fuel’s newest carburetor, Part # BD-1957, addresses these issues, plus is packed full of QFT’s exclusive features such as QuickSet™ vacuum secondaries, Black Diamond™ high temperature coating and a fully adjustable electric choke.

QFT’s BD-1957 was designed as a street performance carb that is also suitable for stock engines. It flows 600 cfm through 1 9/16-inch throttle bores and 1.312-inch venturis.

Quick Fuel Technology™ Introduces BLACK DIAMOND™ Series Carburetors

Bowling Green, KY – Engine compartments are hostile environments for carburetors. Carburetors can reach a peak under-hood temperature of between 180° to 200° F., and the chemical residues in the fuel, oil and coolant can literally bake onto your carburetor and become corrosive over a period of time. While an unsightly looking carb won’t usually affect performance, under-hood heat will. For years racers and tuners have increased performance by lowering fuel temperature. Quick Fuel Technology™ (QFT) has introduced a highly durable Teflon® coating that lowers fuel temperatures by 6% to ensure maximum power and response. It is impact and scratch resistant and also resists corrosion from under-hood chemicals and harsh environments found in marine applications or coastal regions.

The high performance Teflon® coating is designed specifically for the unique requirements of carburetors and is available in a satin black finish. NitroPlate®, an industry leader in all types of high temperature coatings, designed and applies this coating on select SS-Series, Q-Series, and QFX-Series carburetors for QFT.

With the Black Diamond™ Series your carburetor will shed dirt and resist corrosion, offering a showroom fresh appearance and unique performance advantage for years.
