Actuator Question

[im late]

Hey All,

I wish to double check the following:

If an actuator is, for example an 0.8 bar actuator (i.e. HKS 0.8bar Actuator) and you have two of them. Does it mean that the total boost the actuators can support is 1.6 bar?

2 x 1.0bar actuators = 2.0bar

2 x 1.2bar actuators = 2.4bar

etc, etc......

(I.e. this is on a twin turbo setup on a GTR with GT25 framed turbos)

Am I right in what I am stating above?

When an electronic boost controller is set to a level (i.e. 1.6bar) my understanding is that the two turbos are producing a total air pressure of 1.6bar. So that would mean each turbo is producing 0.8bar.

Is this correct?

[R31Nismoid]

1.2 bar actuators is 1.2bar for each turbo

not 2.4

[Fastrotor]

No, if you have 1.2bar, then both turbos are pumping 1.2 bar. The total mass airflow will double however. (assuming everything is equal for sake of this argument)

I used to think this also as I have tested many actuators on GTR's with the mightyvac and they open at 4-5psi individually. That's why I originally asked the question. Still haven't got around to thinking about it some more.

No the flow doubles not the pressure
