TWM
3003 Series units are a direct replacement for downdraft IDA 3C carburetors
as fitted to early Porsche 911, Ferrari 512 and Lamborghini models. The
barrel centers are at 94 mm and the overall height is 123.5 mm. The manifold
mounting flange is identical to the flange on the Weber IDA 3C. The air
filter flange differs from the carburetor in that it uses 6 mm studs which
are 1 mm further apart than the carburetor. Each barrel has an air by-pass screw.
MAP sensor ports are provided on both units. 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 right hand unit incorporates a shaft with a single 5/16 "
D-drive and mounting pad for TWM and other throttle position sensors.
Air horns are not supplied with the throttle bodies. Horns 50 mm long are
available for all bore sizes. In addition, horns 35, 75, 90, 100 and 115
mm are available for the 48 mm bore size. |
