British based Forge Motorsport has released its latest external wastegate for high-performance forced induction cars. One of the key design features of the new unit is the use of a piston-actuated mechanism, which has been designed to withstand large horsepower, boost and temperature figures for sustained periods, without any loss of function.
The piston body is produced from high temperature alloy, and the unit features an Inconel 800 valve and Nitronic 60 valve guide, which has been tested in excess of 900°C. The unit is supplied with three possible boost ports in the base to allow greater flexibility if application is space restricted. Forge also supplies the wastegate with two blanking plugs for this feature, as well as the banjo outlets. The unit is supplied with inlet and outlet mating flanges and ‘V’ band clamps for 360° rotational boost connections.
The unit can be precisely tailored to each individual application with the use of the eight different spring configurations that can be specified at point of order. These allow the piston to open at the desired point in small increments from 2.9 up to 23.2 PSI.
