Overview:

While modifying a street carburetor for circle track applications can work reasonably well, Quick Fuel Technology's Q-Series circle track carbs eliminates the guesswork and offer substantial advantages in adjustability, consistency, and predictability. Since racing around a banked oval pushes fuel to the passenger side of the car, Q-Series circle track carburetors feature die-cast aluminum fuel bowls with internal baffles that eliminate slosh. The bowls also feature an integrated fuel chute that substantially reduces aeration, and directs fuel toward the main jet pickup area. To assist in flattening out the fuel curve, screw-in air bleeds enable fine-tuning of both the low- and high-speed systems, while a proprietary booster design enhances carb signal without restricting high-rpm airflow. Helping drivers put the power down is an adjustable QuickLink system that allows changing the opening rate of the secondaries to 40-, 60-, or 100 percent. Circle track Q-Series carbs are available in 6 different sizes ranging from 650-1,050 cfm for both gasoline and alcohol applications. All Q-Series circle track carburetors are equipped with roller bearing seals which provide smoother throttle response, less wear on shaft, and longer life.

    Best place for head
    Size: Queen (Pack of 1), Color: White
    Do you love not getting sleep and sweating all over your pillow at night when you are asleep? If so then don't buy this pillow! If you want a good nights sleep and cool pillow like me this is the one. Ive always been ehh towards spending so much on a pillow but its 100% worth it, I sleep so much better and it forms to my head and keeps me cool at night. Great support even for my big head and comes with a bag of extra stuffing if you want to have a little more firmer pillow. Highly recommend

    Oversized
    Size: Queen (Pack of 2), Color: White
    I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

    Comfortable and stays cool
    Color: White-cooling Basic, Size: Queen(Pack of 1)
    Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep

    Comfortable and Supportive, but Adjust the Filling
    Color: White-cooling Basic, Size: Queen(Pack of 2), Color: White-cooling Basic, Size: Queen(Pack of 2)
    I’m very happy with this pillow. The size is big and it feels soft while still providing good support, perfect for midnight scrolling on TikTok. One thing to keep in mind is that it can feel a little too tall if you use all of the filling that comes with it. The good news is that you can easily adjust the amount of filling to find the height that works best for your sleeping position. Once I customized it, it was much more comfortable. Overall, great quality, comfortable, and worth the purchase.
