How To Set Hks Actuator's

[sav man]

I got some HKS actuator's for my GT2530's, and I want to set them too 1 bar. i'm using a air compreser, and a boost gauge (use the gauge to ajust the compreser's pressure output) to get the presure right.

But with the accuator attached, and set on the lowest setting that keeps the wastgate closed. The wastgate dosn't seem to open much (~10mm)

I was just wondering if there is an easier way to set these, as the instructions seem to have a x mm=x psi, but i don't read japanise.

Thanks

so no one know's how to set these?

screw them in bit by bit on the car until u get 1bar, my 2530's required 5 turns from std from memory.

how far is the flap ment to open? as i have them out of the car, and i'm not liking the idea of adjusting them in the car.

[BOOSTD]

not much, the arm hole was 100% back behind the wastegate pin...takes a lots of effort to stretch it over.

On road testing is easy...just gradually put the trottle down so your car never has a chance to over boost.

[sav man]

is "not very far" 2-5mm, 5-10mm, more?

[BOOSTD]

only way to know for sure is to test it on the car..drop the rev limiter and raise it slowly if you are really worried about it over boosting

or another one, get someone to pressure test and set the actuator for you:) that way it will be acurate

well i set them, what i did was set the compesser to what the standard accuators are limited too (my EBC reads a max of 0.65 bar when turned off) and i saw how far the opened on the standard turbos. then i just replicated that gap on the new turbos and actuators @ 1 bar.

Thanks for your help

You need to get your hands on the manual that comes with the wastegates it tells you the length you need to set the rods at.... On my gtr from memory for the 1.2bar setting it was 150mm from the back of the wastegate bracket to the centre of hole where it hooks onto the wastegate itself....

ive got one of these aswell.. hmm i dunno if it was setup though.. if my actuator is at like 18psi but the ebc is at 14psi.. what would happen ?

[sav man]

if the actuator is set to 18 psi, then the earlyest it will open is at 18 psi. all the ebc does is control the pressure to the accuator.

[justin911]

oh.. so if im getting 14psi and my ebc is set at 14psi.. then my actuator is obviously at 14psi and theres no point me poking at it ??

You can adjust it by putting air into it (pressure test) and whatever the actuator opens at, that what the psi its set at. And then turn to get it at what you need it at. So i second Devils_Advocate21's post.
