So once the actuator alone is set to say 12psi (standard 4x4) and the Amal Valve reconnected the boost will drop, then its a case of reducing the Amal Valve jet (is this the one to the airbox???) until the boost pressure is back upto 12psi...???
Is that right?
Cheers
you can reduce it by smaller hole in amal outlet to actuator or increasing hole in outlet to airbox,i tried the latter and could not get it right.....so i lathed up a piece of nylon the size of amal outlet i/d and cut a piece about 5mm long...drilled 1mm hole in it ,removed original restrictor and superglued it in.....i had already set up actuator to hold 26psi by running with pipe disconnected and gradually shortening actuator rod....when i connected amal valve i tested and it was the same so gradually opened hole (1/2mm)at a time until when run boost would tail off and hold 23 psi
