Like the MG, The new manifold / plenum bolts to the bottom half of the OE manifold.
Only part machined here. The lug on the side is to clamp it to my machining fixture. It gets cut off later.
The Autorotor supercharger is a great unit.
The narrow section of the plenum is a blessing as it assists with even air distribution to all cylinders.
Supercharger installed. The blue hoses are oil feed to the gearbox fed off the oil pressure.
Vacuum line to make the bypass operate.
Vacuum actuated bypass valve. The bypass opens at idle to control inlet air temp at idle.
Additional fuel injector into the supercharger inlet.

Two stays at the rear of the engine give the new manifold additional support.
The throttle sits in the same location in the car as before. This helps with wiring and throttle / cruise control cables. I used the original duct from the throttle to the filter housing.
Bypass ports in the inlet manifold.
Supercharger drive support bar.
Cut the old engine cover to go around the new installation.
