These 4 progression hole versions of the 45 DCOE tend to offer a better solution to fitment on modern 16 valve engines such as the Vauxhall XE although we recommend the 5 progression hole version for Ford Zetec and Duratec applications.
Please see the other versions available for versions more suited to older 2 valve per cylinder engines.
The carburettor is supplied with a pair of trumpets, single inlet fuel banjo and a throttle lever. We are able to supply a range of parts to allow fitment of multiple carburettors to an engine are available.
As standard the carburettor is supplied with the following calibration but it can be supplied jetted to your specification if required:
Aux Venturi 4.5
Main Jet 145
Air Corrector 155
Emulsion Tube F16
Idle Jet 55F8
Needle Valve 200
Pump Jet 50
