For those thinking of replacing Bendix style mechanical injection with EFI, we now have CNC'd throttle bodies to bolt directly in place of RSA-10 servos on forward facing IO-540 sumps. The throttle plate is 80mm and the air horn base accepts 4 inch ID SCAT hose, K&N filters or Silicone couplers. The TB has an O-ring seal on the base so gaskets are no longer required. The shaft is Stainless, supported on sealed roller bearings. The throttle arm is 7075T6 and incorporates internal stops. Under 2 pounds total weight and mounts an OEM Bosch TPS. There are no internal restrictions like on Bendix/ AFP servos so the body offers full manifold pressure potential up to 375hp.
