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.

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.
