boost drops off

[mrpeal55]

is the boost on my ep82 supposed to start going down at high revs?

 

[GT-TD04]

yep its going off boost...

it does if you have standard actuator.

Fit a HKS actuator and you will hold full boost.

 

[mrpeal55]

cheers mate dont suppose you know how to stop it doing it ?

 

[GT-TD04]

get an upgraded actuator as said above..

 

[mrpeal55]

i think the actuator has been uprated because i have adjustable boost in car and i don't think ep82's have adjustable actuators as standard

 

[GT-TD04]

maybe its bost leak,is it a serious drop and how long(in rev) does it hold boost??

 

[mrpeal55]

it reaches full boost and then it starts to go down after a second or so

You can adjust boost with the standard actuator so you cannot assume you have an upgraded actuator. Take a look under the bonnet and see.

My boost uysed to drop off at high revs, from 10psi to 4/5psi. But I re-fitted the EFI pipe (air intake pipe) and made sure the rubber insert was put in properly 'cos before it had bent over restricting airflow mega style. Now I can hold 9/10psi constant to red line!

 

[GT-TD04]

sounds about normal,do you change boost with the in car controller (like an mbc or ebc)

do you know what an acuator is??

 

[jamesbaa]

sorry to hijack the thread but a simila things happened to my ep82, when i first got the car it was boosting to 10 psi, but i fitted a new bov, and now it only boosts to around 8 psi.

 

[mrpeal55]

yeah i know what an actuator is, my boost controller is one you turn there is to red pipes coming from it one goes to the actuator and i dont know where the other one goes

i have an ebc and hks actuator and my boost used to drop off after about 5k rpm with both the efi pipe fitted and with mesh over the intake. with a front mounted air filter it now boost creeps for the first time ever.
