8500SL Series Throttle Body

If you would like to switch from a carburetor intake to electronic fuel injection (EFI), Accufab has developed the 8500SL high flow throttle body to meet your needs.

Better Air Flow for More Power. The Accufab 8500SL series 4-barrel throttle body uses the same 2.75-inch bores as the dual-bore “split Dominator style” units and flows 3,600+ 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.

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.

Our concept was to develop a new 4-barrel throttle body with a 33-square inch area. This size provides a 50% 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 figure out how to modify their existing 4500 series intakes to accept the 8500 throttle body with its slightly larger bolt pattern. A sheet metal plenum style intake manifold can be used as well.

Exceptional Quality. The Accufab 8500SL 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 throttle linkage is included. Each throttle body weighs 3.5-pounds, compared to up to 13-pounds for a big 4500 series carburetor. Manufactured in the USA.

These throttle bodies (8500SL) are exclusive to Sonny's Racing Engines
