Trying to set the boost on stage 1 saph. set the preload on it, half moon, that should be about a bar. However, its boosting over 20 and thats only going up to about 4.5rpm before backing off cos its way too much god knows what it would be if i floored it
even if i turn it down more it still boosts the same.

Now, would that be indicative of a fucked actuator? or am i being a pleb?

 

are the vacuum hoses the right way around on the amal valve unwind the actuator arm if that don't work then I would join the vacuum pipe from the compressor housing to actuator and go from ther to see if the amal valve is at fault

 

Perhaps the jets on amal valve have already been modified? Its not a mechanical bleedvalve on there either is it?

 

HI,

Or you could disconnect the amal valve, and you should have just
actuator pressure, if so you need to check the amal valve and jets
in it.

Im 99.9% sure the hoses are right. If it runs properly with the vacuum pipe from compressor housing attached to actuator does that mean the amal valve is faulty then?

thanks

and no, its not got a bleed valve on it.

 

It doesnt mean its faulty, might just mean its got wrong sized jets.

but thats the place to start, as then you can see what the actuator is set to if you run it straight off the housing

 

its the same amal valve ive run on it for ages. cars just been off the road for a while and since its been back ive not been able to set the boost right.

Will give it a go with the amal valve disconnected though

cheers

 

i was right put a bleed valve on it the brass one with the locking nut on it

 

certainly not fucked actuator, the opposite in fact!

 

dude the amal did take a nock loop out amal should run same as 3dr did about 8 psi

 

Stick the bleed valvle that I have sat here on it!

 

It amal valve related definatly mate
Either its fooked or you have lost a jet!
Got a few here should you require a replacement

 

sorted u da bitch pon

 

holds much lower boost now so deffo amal valve as you've all said

cheers Rich & Spadge, i'll let you know
