Quick Fuel QFX-Series Carburetors

These Quick Fuel QFX-Series carburetors feature an all-new die-cast aluminum main body, which has a lengthened venturi section for greater midrange torque and better airflow. The annular booster venturis are precision die-cast with CNC-machined billet aluminum inserts, providing smoother and more refined air entry, a stronger vacuum signal, less turbulence, and improved fuel emulsion for better combustion. The Quick Fuel QFX-Series carburetors use red anodized billet aluminum CNC-machined metering blocks featuring 3-circuit metering (gasoline carburetors), changeable emulsion, idle feed, and intermediate bowl and feed discharge. Next, the die-cast aluminum fuel bowl combines high strength with significant weight reduction. They feature dual threaded fuel inlets and outlets and dual sight glass holes to easily set the float levels. The Quick Fuel QFX-Series carburetors feature Quick Fuel's external linkage with four different links to select the amount of primary throttle opening before the secondaries open: moderate progressive (25 percent), medium progressive (40 percent), full progressive (50 percent), and 1:1.

Injector Dynamics ID1750x Fuel Injectors

The best just got better! Injector Dynamics ID1750x fuel injectors are a built-to-spec motorsport injector, offering optimization of critical operating parameters important to you, the motorsport tuner. Built on the evolution of the ID1700 and X Series, these fuel injectors are a drastic improvement over previous series from Injector Dynamics. Compared to the 1700, the 1750x offers: higher dynamic flow rate with no increase in minimum fuel mass, better cylinder to cylinder balance at low pulse widths, and improved pressure sensitivity—all while retaining the same "compatible with everything but dirt" corrosion resistance that made the ID1700 famous. Plus, a unique magnetic circuit, resulting from a lengthy development program, makes the ID1750x immune to voltage and pressure sensitivity problems that plague other high impedance high flow injectors. Order the set of fuel injectors recommended for your vehicle. Key features and benefits include: * Compact body design allows fitment in a variety of applications * Higher dynamic flow rate with no decrease in minimum fuel mass * Better cylinder to cylinder balance at low pulse widths * Improved pressure sensitivity * Corrosion resistance makes these fuel injectors compatible with Methanol/Ethanol/MTBE/Nitromethane and all known Hydrocarbon fuels * Unique magnetic circuit makes the ID1750x immune to voltage and pressure sensitivity problems that plague other high impedance high flow injectors * Narrow spray pattern—minimal wall wetting promotes quick response and smooth running * Does not require extended linearity at low flow rates

Nitrous Express EFI Race Single Nozzle Nitrous Systems

These Nitrous Express EFI Race single nozzle nitrous systems are great for vehicles with limited room in the engine bay, especially those with minimal hood clearance. However, despite their relatively compact nature, they don't short you on power delivery. The heart of these systems is NX's potent "Shark" nozzle, which means that they can deliver power increases from 100 to 250 hp. Best of all, these increases are in graduated increments that you can select. The kits include the nitrous bottle, mounting brackets, nozzle, nitrous supply hoses and fittings, solenoids, switches, wiring, jets, and mounting hardware.
