Coming from the older school of car mechanics, when Dynamos and Control Boxes reigned supreme, and when the Carburetter was king, and basic engine functions were Suck,Squeeze, Bang, Blow.  Is it not possible to disconnect this Multiram gizmo, and just have air going into the cylinders?  without it being pushed and shoved this way and that. By the way my system is working correctly

You could disable the actuators by blocking off the vacuum pipes.

I too remember voltage control boxes, carbs, dizzis etc and can go even further to thermo-syphon cooling, heaters as optional equipment, battery charge control by moving a third brush on the dynamo and headlamp dipping by physically moving the (RH only) headlamp by solenoid BUT I would not want to go back to the poor starting, low performance, flat spots, poor economy etc that went with it. Technology marches on, better to try to understand it than rip it out

The multiram does a VERY good job of flattening out the torque curve and hence aiding economy.

You need to consider that for optimum torque you need high air speed in the inlet........so if the inlet is small and long you get high inlet airspeed at low revs but a restriction at high revs (good bottom end torque but nothing higher in the rev range), if its short and large you get low inlet air speed at low revs and good inlet air speed at high revs (no bottom end torque)......the multiram allows a good compromise on both i.e. high air speed at low revs and and high air speed with low restriction at high revs.....its a dam good system.

Thanks Pete/Mark I thought there might be a reason for it being there. By the way Pete you forgot semaphore signalling/ side valve engines and on my first car, Rod Brakes (hand brake and foot brake operating the same system) and finally the windscreen had a handle to wind it open Grin (hope I haven't gone off topic to far Wink

Add vacuum wipers, plywood floors, suicide doors, hand-scraped whitemetal big end bearings and , just to bring it back on topic, an adjustable intake system. (winter / summer)
