Accufab 4-Barrel 9500 Competition Throttle Body - Polished

If you would like to switch from a carburetor intake to electronic fuel injection (EFI), Accufab has developed the Four Barrel 9500 high flow throttle body to meet your needs.

 

Part Number: 4B-9500

 

Better Air Flow for More Power. The Accufab Four Barrel 9500 Throttle Body uses 3.5-inch bores and flows 5,476 CFM at 28-inches. There are no 4-barrel carburetors that can come close to matching that flow rating. If that’s not enough, racers can mount two of them together for double the volume.

In many race classes, racers are limited to a single 4-barrel carburetor or a single throttle body. Accufab used a clean sheet of paper and came to the conclusion that the standard intake manifold opening for the largest carbs available (the 4500 series) was just not adequate. The 9500 will not bolt up to a 4500 style intake manifold, which uses a 5.375-inch by 5.375-inch bolt pattern. The attachment bolt pattern for the 9500 is 7.0-inch by 7.0-inch and the required intake plenum opening needs to be at least 7.25-inches square.

Accufab’s goal was to design a better 4-barrel throttle body without trying to make it fit on the existing 22-square inch 4500 series intake manifold inlet opening, an inlet opening that was originally developed in 1969. The correct 9500 inlet opening is 52.5-square inches.

This size provides a 250% increase! Racers, or intake manifold manufacturers, will come up with better intakes to match the increase in air flow. Also, racers are creative and will most likely use a sheet metal plenum style intake manifold.

  • The Accufab 9500 throttle body is made from 6061-T6 billet aluminum and polished to an eye-catching finish. Accufab’s quality is second to none! Only the best components are used for unparalleled reliability and performance. Center-dump type progressive throttle linkage is included. Each throttle body weighs 4 pounds, compared to up to 13-pounds for a big 4500 series carburetor. Manufactured in the USA.

Application: These throttle bodies may be used with either EFI or mechanical fuel injection. For an EFI application, the throttle body is CNC machined to use a Ford Mustang 5.0L 1986-1993 throttle position sensor (TPS). Accufab has an optional adapter to accept the GM TPS if needed.

Accessories Included: None.
