Precision Airflow for Tillotson Carburetors

As one of the premier go kart suppliers, we know that maximizing airflow into your Tillotson carburetor is the difference between pulling away on the straightaway and getting left in the dust. The EC Carburetors EC-319VS Billet Velocity Stack is engineered to replace restrictive standard filter adapters on Tillotson HL-304WXA, HL-348, HL-355, and HL-360 series carburetors. By utilizing a carefully contoured internal radius, this velocity stack smooths and accelerates the incoming air charge. This increased velocity boosts the carburetor signal, resulting in superior fuel atomization, crisper throttle response, and a broader powerband when you need it most.

Billet Aluminum Construction for High-Demand Racing

When you are turning high RPMs and demanding peak performance, plastic adapters simply flex and fail. CNC-machined from aerospace-grade 6061-T6 billet aluminum, the EC-319VS delivers unmatched strength and precision. The rigid mounting surface ensures a perfect seal against the carburetor body, preventing lean conditions caused by air leaks. Whether you are dialing in a fresh carb kit or optimizing your current setup, this velocity stack ensures consistent, reliable intake flow under the most extreme racing conditions.

Seamless Integration with Your Racing Setup

Tuning a winning kart requires attention to every detail, from your engine drive belt tension to your tire pressures. The EC-319VS features a standard 2.5" Outer Diameter (OD), allowing you to easily mount high-flow, clamp-on air filters. This streamlined integration keeps dirt and debris out of the venturi without sacrificing the volume of air your engine demands. While you might be focused on a go kart steering wheel upgrade for better handling, don't neglect the engine performance that gets you to the next corner faster. Pair this stack with premium go kart wheels tires to translate that newfound torque directly to the asphalt.

Frequently Asked Questions

Q: Will this velocity stack fit my Tillotson carburetor?

A: The EC-319VS is specifically engineered for the Tillotson HL-304WXA, HL-348, HL-355, and HL-360 series carburetors. Please verify your specific carburetor model number before purchasing to ensure a proper fit.

Q: Does this velocity stack come with the necessary mounting hardware?

A: Yes, the kit includes all required 8-32 mounting bolts to ensure a secure, leak-free installation directly to your carburetor body.

Q: What size air filter should I use with this adapter?

A: This velocity stack features a standard 2.5" Outer Diameter (OD), which is designed to accommodate most standard high-flow, clamp-on racing air filters.

Q: Why should I choose a billet aluminum stack over a plastic one?

A: Unlike plastic adapters that can flex or crack under high-RPM vibration, our 6061-T6 billet aluminum construction provides a rigid, durable mounting surface that prevents air leaks and maintains consistent intake geometry.

Q: Is this velocity stack legal for all karting classes?

A: This product is designed for high-demand open and modified racing classes. Because rules vary by track and organization, we strongly recommend checking your local rulebook to confirm velocity stack legality for your specific class.
