Overview:

In circle track classes that mandate two-barrel carburetors, customizing a street carburetor has been the norm for decades. Not anymore. Designed from the ground up to meet the unique demands of circle track racing, QFT's new XP-Series offers the performance benefits of a custom carburetor in an affordable, turnkey, class-legal package. At a bare minimum, modifying a standard street carburetor for circle track duty typically involves changing the throttle-plates, floats, and metering blocks. These custom modifications can easily exceed the cost of a turnkey QFT two-barrel carb while still lacking many of the key features that only a clean-sheet redesign can offer. A high-flow aluminum main body design centers the venturi over the throttle-body assembly. To further increase airflow, QFT centers the air horn over the venturi, removes the choke tower, and carefully profiles the air inlet transition. The result is enhanced airflow and fuel distribution, which improves throttle-response and horsepower. All XP-Series carburetors are equipped with roller bearing seals which provide smoother throttle response, less wear on shaft, and longer life. Available in 500- and 600 cfm sizes, the XP-Series sets a new standard in two-barrel circle track carbs. High-flow aluminum main body with centered venturi for improved performance and better air/fuel distribution Black anodized billet 2-Circuit metering block and throttle body Throttle body incorporates roller bearing seals which provide smoother operation, less wear on shaft, and longer life Anti-siphon check valve in main body to reduce pump pull-over Changeable emulsion bleeds and power valve channel restrictions for better tuning capabilities Dual inlet fuel bowl with #8AN fittings Dual sight glass windows for easy float adjustment Single wedge circle track float Exclusive Black Diamond® coating for enhanced corrosion protection and appearance. Provides a 6% reduction in fuel temperature.

    Best old guy shoes. They look great and have support for feet. You don't want cheap department shoes. You will pay for that in your later years.

    Good comfort, quality and classy
    Size: 8.5, Color: Black/Ivory
    ’ve been wearing Cole Haan dress sneakers for work and travel, and they strike a really good balance between professional and comfortable. The biggest advantage is how lightweight they feel compared to traditional dress shoes. Most styles have sneaker-like cushioning, so you can walk or stand all day without your feet getting destroyed. The design is also versatile and look polished enough for business casual outfits but still casual enough to wear with jeans. They work especially well in office environments where a full formal shoe feels too stiff or outdated.

    New Favorite Work Shoe

    These Cole Haan Grand Crosscourt Daily shoes have quickly become my new favorite work shoes. They’re incredibly comfortable right out of the box, with just the right amount of cushioning and support to get through long days on my feet. I love that they look sleek and professional while still feeling casual enough to wear anywhere. The build quality is top-notch—durable materials and solid construction that make them feel like they’ll last a long time. Overall, these shoes strike the perfect balance between comfort, style, and practicality. I can honestly say I look forward to wearing them every day. Highly recommend for anyone who spends a lot of time on their feet but doesn’t want to sacrifice style.
