It’s prone mostly to V8s that are force-fed with a large Roots-style supercharger. A screw blower is able to deliver the air into the engine in a more efficient manner, as the rotors that capture the air reduce in size as they’re turned, which in turn causes the air to be compressed as it’s introduced into the manifold. Check the blower motor at its two-wire connector for power. That bypass mode feature reduces the parasitic power drag on the engine. The main drawback to Roots-style superchargers is the consistency of the air charge. Driving these rotors pushes air into the intake-manifold cavity at a greater rate than the engine can ingest the air. Like the turbo this requires high RPM to generate the PSI. If there is no power, check the resistor for power. This creates pressure simply due to volume of air being moved rather than keeping the air from escaping. Why might you choose to change to using an aftermarket throttle body? BSFC (Brake Specific Fuel Consumption) - How is this a beneficial measurement? A Roots-type blower pulls in air and compresses it in the engine’s cylinders.
