MED WEBER 45DCOE STUB STACK KIT
( £50.00 EXC VAT )
The “DCR” system has also been dyno tested on numerous race engines with the 45 DCOE carburettor and produced a gain of between 4 to 6 BHP over the 45 DCOE carburettor with standard Weber ram pipes.
The central velocity stack creates more airflow into the auxiliary venturi, which will increase the air speed over the venturi which in turn amplifies the mixture signal thus bringing the engine onto the cam earlier.
The stub stack with optimised elliptical form smoothes the airflow entry into the choke area thus creating more bhp throughout the range.
This is also aided by the full flow open backed ITG filter.
The carburettor inserts fit inside the carburettor to replace the standard ram pipes, these are manufactured with a spigot on the top face to locate the ITG filter base plate and stub stack, which in turn has a recess machined into the rear mounting face to locate onto the inserts.
The velocity stub stack spacers then locate in to the stub stack with the velocity stacks fitting onto the top of the spacers.
The two 6mm button head screws then locate the complete assembly onto the carburettor
