Actuator On Ba 03

[jdmullet]

Sup,

Just trying to understand what ive read in one of the ford magazines I bought. So at stock the BA 2003 turbo is set at 6psi boost right? but to my understanding it has a actuator which is basically a spring loaded diaphragm/valve which is only capable of holding 2psi boost. So does this mean although the turbo itself is set to 6psi boost its only making 2psi because it cant hold the pressure in for long enough?

Sorry if this is a dumb ass question but im 19 and trying to take in as much as I can regarding turbo's and fords in general.

Thanks for your time.

some one else will know more about this ,from my understanding the actuators are rated at the minimum boost they will hold not the max.a lot of the stock ones hol 12 psi after that they tend to have trouble ,from what I've read you need to use an actuator that is close to the minimum boost you want run ,if you want to run 10 to 12 psi get a 8 to 10 psi actuator ,

does that mean because ive bought a turbo with an actuator upgrade (for my n/a) im gonna have to have to rum 12 lb and above

Pretty much, but I think you can run lower by your tuner asking for zero boost duty. Don't quote me, but I'm sure I've seen someone write about it before

[ETM]

you cannot run lower boost than what the spring is set as, the lowest possible boost setting can be achieved by bypassing the solenoid and going direct from the compressor cover to the actuator

that's how ive got it setup .compressor cover---- boost controller------- wastegate

So does anyone know the stock boost rating for the actuator? and is it set to 6psi from stock? (factory)

Thanks for your input

as I said mate stock ones will control around 12 _13 psi after that they become hard to control boost properly

if your guna turbo a na engine, u dont want big boost, as your comp is high, and the engine then wont last
