HKS 2530 boost question - spiking, HELP PLEASE!!!

[Hawker180]

Just a quick question about my HKS 2530 turbo,

Im experiencing some boosting issues with it, its spiking to 1.3bar sometimes and is only ment to be tuned for 1.2bar! Even with my AVCR turned OFF!!!

How do a back off the boost on the turbo??? do i make the acuator arm longer? Im trying to electronically control the boost with my AVCR but even when i turn the boost controller off it still spikes and boosts to 1.2bar (spiking at 1.3bar)

Ideally id like a low boost setting 1 bar and a high 1.2 bar, so id like it manually set to 1 bar!

Thanks

Here is a pic of the Accuator Arm

Anyone know how to adjust the boost????

Mate, as far as I know, its the size of the spring that sets the base boost level..... Maybe take it too a turbo specialist and get them to put a bit smaller spring in the wastegate setup. This is not my field of expertise, so don't flame me if im a little sidetracked.

Lengthen the actuator arm to make less boost, shorten it to make more boost. I control my boost by the actuator arm only, i have no boost controller

Yep, lengthen it, set it for the lowest boost you want to run with the avcr off.

Then reset your avcr for 1.2 bar as it will need to run a higher duty to make the same boost

you cant run less boost than the base spring allows. if its a 1.2 bar spring, then thats as low as you can go. Altering the rod length wont work for you.

i was told it was 10psi actuator when i got it, but then i never saw boost that low... as in pm, get a r33 stock actuator and you'll be sweet.

Cool thanks for your replies, I lengthened the arm and now it is boosting to 1.1bar, i still have to adjust the duty on the AVCR to make it boost to 1.2bar

Thanks for your quick responses!

Good stuff.Mine is over boosting also but with the standard RB20det actuator,16psi with no boost controller.I'm hoping the hks actuator will stop this like yours.
