ESPRIT 2.2 CARBURETTOR TURBO DUMP VALVE KIT 

This kit is for all Stevens Carburettor Turbo models.

A dump valve is an air pressure bypass valve that is placed between the turbo compressor and the throttle.

Fitting a dump valve will improve emissions, fuel economy and driveability. 

The dump valve can help achieve higher boost levels whilst reducing stress on the turbo allowing a better throttle response.
