3004 Series, DCNF Style
TWM 3004 Series are a direct replacement for the DCNF carburetors fitted
to Ferrari, Maserati, and Aston Martin, in addition to having a number
of aftermarket applications. The unit is extremely compact with barrel
centers at 48 mm and an overall height of 86 mm. The manifold
mounting and air cleaner flanges are identical to the DCNF carburetor.
TWM DCNF throttle bodies are equipped with pockets for Bosch, Lucas, and
Weber injectors, using an O-ring top and bottom. Each barrel has an air
by-pass screw.
There are integral mounts for the fuel rail which is supplied with the
unit. AN-6 threads are in each end of the rail for which a specific fitting,
part number 2900-9206, is available.
The left hand unit incorporates a shaft with a single 5/16 "
D-drive and mounting pad for TWM throttle position sensors.
