just a quick question. What difference will the amal valve make being unplugged or plugged in on a stage 2, 195spec fiesta turbo running ofab h reg. And how do you tell if you got a -31 actuator cheers guys

 

the amel valve controls the boost would not unplug it as the ecu will be blind as regards the controlling boost

 

if u unplug the valve u'll only get the boost ur actuator is set at,which will be less its like having a two stage switch hi/lo and ur actuator will/should have -31 stamped on the back of it

 

if its a -31 will be no more then 8 psi

 

...shut up............. trust me its more and if it wasnt a shit night i'd go and try it

 

Okay cheers guys will connect the valve up i need to connect a multi-plug onto the end of the wires and ideas on which way round they go etc, and also which way round the pipes go to the amal valve cheers.

 

lol i feel that a -31 spring can only hold 8 psi without any control in place and a -34 can hold 14.5psi

 

not sure bout the wires but the amel valve should have lettering on the outlets,W= wastegate(actuator),C=compressor housing(just goes to your turbo)A= atmosphere will it open to air

 

the car holds 13psi on the boost guade at the mo don't know if thes helps

 

where r the vacuum pipes going from the turbo

 

Just onto the actuator one from the compressor housing onto the actuator, and its a T3

 

Also it has no bleed valve or manuel boost controller valve or simular on the pipe so won't this increase lag etc, since the wastegate will start opening too soon.

 

hmm in that case prehaps i am talkin poo always thought a -31 will only hold 8 psi without any form of control?

 

okay i've just connected the pipes up i couldn't see any markings on the amal valve so guessed the car then was over boosting to about 16-18psi and then suddenly cutting the boost etc. So i swapped the pipes over but still is the same i had the actuator set at 12psi when it was just connected on its own and not to the amal valve etc. I had to also rewire a multiplug on the end of the wires so don't know if i done it the right way round etc. Are these palarity concious. And is there a way of testing the amal valve. It only had 2 outlets etc. And looks be a genuine ford one. Cheers

i wouldnt run it anymore then 16 psi unless youve uprated the bottom end,the resistance of the amal valve should be between 30 and 120 ohms while it is disconnected

 

Depends on how its preloaded when its fitted
on the bench, not attached to anything they crack around 8-10psi if fitted with very small preload you usually end up with 8-10 psi on the car.
but shorten the rod a lot and you could end up with 15+psi
