With all the new Accufab throttle body products we have developed recently for the N/A Pro Stocks or Nitrous Oxide Pro Mods, it’s definitely time to fill in the gap for the forced induction Pro Mod racers, running the huge new centrifugal superchargers or bigger dual-turbocharger combinations. Our new 125mm throttle body is just the ticket for racers in the 2,500 to 3,500 horsepower range.

Note: The stainless steel 5.5″ V-Band clamp and matching 5″ ferrule are sold separately. Please find them for purchase under the main menu “Clamps”.

Better Air Flow for More Power: The Accufab 125mm flows 2275 CFM.

Exceptional Quality: The Accufab 125mm is made from 6061-T6 billet aluminum and polished to an eye-catching finish, plus our quality is second to none! Only the best components are used for unparalleled reliability and performance. For example, this unit features a stainless steel split shaft design with four ARP screws to hold everything securely together. Also, new to this throttle body is the linkage with two threaded holes to utilize a 10/24 threaded ball stud or your choice of other products with this thread size. You can use either hole, depending on your application, to open the throttle blade correctly. Manufactured and assembled in the USA.

Application: This throttle body may be used with an intake manifold featuring a 4.5″ bolt center to bolt center square bolt pattern. In addition, these units have a built-in V-Band ferrule machined on to the leading edge. The ferrules are designed for a 5-inch intake pipe leading up to the throttle body. Also, an o-ring groove is machined into the rear of the throttle body, guaranteeing a leak-free seal to the intake manifold. In regards to the TPS application, the throttle body is CNC machined to use a Ford Mustang 5.0L 1986-1993 3 wire pig tail style TPS. However, Accufab has an optional accessory to help adapt this Ford style TPS provision to be used with late GM electronics instead, see our part number TPSGM. Furthermore, there is no IAC provision on this throttle body.

Accessories Included: O-ring for the rear to manifold side. All other parts sold separately.
