13psi Ecotec.wmv

VS V6 Commodore with Raptor ProStreet Intercooled stage 3 system. Running 13psi in the manifold this is a test unit to gauge long term effects on the system. The power and torque have obviously increased and a retune is now needed. The extra stability of the air system has shown remarkable improvements in fuel economy, the large 32mm BOVs are responsible for this. The 4" intake assists with flow into the compressor as the SC is delivering enough air for around 350hp at the wheels with a good tune
