No. If you use the method below, the pressure across the supercharger will be equalized by the diverter when the clutch is disengaged.just trying to work out, if it was plumbed this way and you disengage the charger does the manifold pressure not back feed through the charger?
Say, for this example, the SC is setup to make 15psi.
Use a traditional wastegate actuator with a 14psi cracking pressure to control the diverter movement. That will limit manifold pressure so there isn't a pressure spike from the SC multiplying the pressure ratio as the turbo spools up and pressurizes its inlet.
As the turbo spools up, the diverter will be fully open around 16psi and the SC will have equal pressure inlet and outlet (basically just moving air from A:B).
At that point, a manifold pressure switch (Hobbs switch) set around 18psi will disengage the SC's clutch automatically.
With the above, there will be no manifold pressure spike, boost drop or back-flow to the turbo.
The SC will automatically re-engage as pressure drops below 18psi and the SC, clutch and turbo will not be shock-loaded because airflow from the turbo is still above the SC's natural flow range.
Its simple, reliable, effective, no computer BS and it doesn't need any driver attention.
I have no association with those hacks.from stuporturbodiesel.
