Adjusting Hks Internal Wastegate

[Jsikalias]

hey guys iv got a problem i have adjusted the length on the actuator to pritty much the minimum boost which is the longest and iv set my EBC too 10 duty cycle and 0 gain and i see 16-17psi how do i get it to 10psi i dont think im adjusting it right do i just turn the rod on the end?

Aren't the spring pressures in the HKS actuators around 15psi? How much boost are they meant to hold with zero bleed?

i thought they where around 10 to 20psi

the longer the rod thing is the less it holds.. so if u wana make it 10psi u goto make it longer. i found if u make it to long tho its crap and is realy realy laggy. disconnect ur ebc and see wat happens also

Wind the rod out till there is no preload on the wategate flap and run you boost line straight to the acuator and then see what boost you get. If you still only get 16Psi then thats the minimum you likely to get unless there is something else wrong with the car.

i found that the wastegate flap isnt smooth when opening and closing its getting stuck and it moves up n down a little where the wastegate rod connects too is that normal ...never ending boost problems lol b4 i was loosing boost at high rpm now im getting too much lol

the flap was touching the divider on the split dump pipe... i have taken the divider off is that bad ??? and also where do i get a bellmouth one but withought the front pipe

[Jsikalias]

i tryed running the wastegate on its own and for some reason it wont boost more than 8 but if i connect the EBC it will boost too 15psi? how do i get just the wastegate working? because the boost is still droping at high rpm

[Jsikalias]

i connected the tube from the intercooler piping to the wastegate? is that correct

[huddy]

yes

that will make it run 'standard' boost (what the actuator is set at)

eg boost it - it will read maybe 8psi.

if you want it to have more boost, then shorten the rod, and repeat the process.

do this until you find the right boost level, and then attatched and resetup ebc
