Overview:

Serious drag racing demand a serious drag racing carburetor, and the QFX-Series stands as the flagship model in QFT's lineup. Raised air horns improve entry angle into the venturi while ensuring undisrupted flow over the air bleeds. Annular boosters with CNC-machined billet aluminum inserts provide increased air flow, a stronger signal, and less turbulence. QFX carbs offer unparalleled fuel atomization with annular boosters specific for either gas, methanol, or E85 fuels. Five-emulsion billet metering blocks and four-corner idle circuits offer flexible tunability that today's high-horsepower engines demand. To cover a broad range of applications, methanol- and E85-compatible models, as well as two- and three-circuit fuel systems, are available. Ready to run out of the box, the QFX-Series carburetor will help you get to the winner's circle.
Even a carburetor that performs great can still be an eyesore, but it doesn't have to be that way. Quick Fuel Technology's proprietary Black Diamond® coating offers excellent corrosion resistance as well as a durable finish that easily stands up to dirt and oil. In addition to great looks, the PTFE coating reduces fuel temperature by six percent for improved performance.

    Fun and Tough Interactive Toy for My Big Dog
    This interactive dog ball has been a great addition for my large dog. The ball’s material is very durable and holds up well even with heavy chewing. My dog usually destroys toys within days, but this one has lasted weeks and still looks great. The automatic play modes keep him active and entertained, especially when I’m busy. He loves chasing it both indoors and outdoors, and it helps release his energy. The battery life is decent, and the operation is simple. Overall, it’s a fun, sturdy, and smart toy that really keeps my dog busy and happy

    Finally, a Toy That Keeps My Dog Entertained and Active
    I bought this interactive dog ball for my German Shepherd, who is very energetic and can be quite aggressive with his chewing. I've tried countless toys that either failed to hold his attention or broke within a week, but this ball is incredibly durable. The durable E-TPU material feels tough and flexible, yet lightweight, making it easy for him to carry around. The bright blue color makes it easily recognizable indoors or out, and I can spot it at a glance. The ball bounces and rolls in unpredictable patterns, keeping him alert and focused. When he tires of chasing, I switch it to slow mode so he can push the ball around easily. I've noticed he's calmer after playing in the evenings.

    Great way to keep my dog entertained!
    My German Shepherd gets bored easily and tends to chew through most toys, but this interactive ball has been a lifesaver. The durable E-TPU material really holds up against his strong jaws. I love that it has 3 different play modes – it keeps him curious and busy for hours, both inside the house and in the backyard. A perfect mix of durability and fun!

    Sturdy interactive ball that keeps my dog engaged
    I’ve been using this ball with my dog, and it’s held up well during supervised play. The three play modes are easy to switch, and he stays interested longer than with his usual toys. I mostly use it indoors when I’m working, and it helps keep him occupied. The material feels durable and safe, and I like that it’s easy to rinse off after outdoor sessions. Charging is quick with the included cable, and the mesh bag is handy for bringing it along to the park. What I noticed most is how much mental stimulation it gives him, especially when he starts to get restless in the afternoon. It’s become part of our daily routine.

    My dog loves it
    My 70 lb 1 year old dog plays his own soccer with this toy and he loves making it squeek but he is a toy destroyer and so far this has held up pretty well. It's made of a soft material so I don't have to worry about it harming his teeth. It's easy to clean. It can be used in the house or outside for fetch. It is unpredictable at times with its bouncing which makes it more interesting for my dog to chase after. This is his favorite toy and carries it everywhere including to bed.
