Ever wonder why your new, out of the box carburetor doesn't work well on your modified high performance engine? Well, your motor is requiring more or less fuel in certain throttle positions than the factory has calibrated that stock carb to deliver.
This is where ACFI can benefit you immensely...we build custom carburetors specifically for the engines they will service. We know that no two customers are building the same motor so we don't build 'stock' carbs -- we build carbs finely tuned for your engine's specific needs.
We have extensive experience and great success in building CIRCLE TRACK, SUPER CHARGER and BLOWER carbs for Drag race, and Street performance use. Custom designed Holley, Edelbrock, Demon, Weber, and Quadrajet carbs for racing applications no trouble at all. We build them in most cases from new castings (Holley and Weber carbs) and do all of the machining and sub-assembly work before each Holley carburetor is assembled.
All custom carburetors are vigorously tested on a live engine before they leave the shop. Just provide our technicians with your engine and drive train specifications and we will do the rest.
Made a mistake and already bought a new stock carburetor from a mail order parts company? Have no worries - we can still get you running much more efficiently and give you that 'throw you back in the seat' feeling that you're looking for. With our re-calibration service you can get what your motor wants when it wants it.
