2860-5

[DAS KAMU]

Hi,

What are the out of the box specs on the standard psi 2860-5's are set up for?

as in it there was no bc present what would they run ?

[JonnoHR31]

whatever the actuators you order are rated to

i was not given the option?

i was not given the option?

then call whoever you are buying it from

right

[Rolls]

right

actuators aren't that expensive if what they are sending you isn't what you want. Aim for as close to whatever boost you are aiming to run. Don't say get a 10psi actuator then try and run 22psi, you'll run into problems.

[DAS KAMU]

there on the car sorry

but the solenoid for the bc is dead and was just wondering

[DAS KAMU]

i officially have no boost control at all

the actuators must be set sky high as well and with the controller unplugged its still hitting over 1.5 bar

[Rolls]

22psi is about what most people would run on that turbo, I'm assuming the motor is build and tuned for that? what is the issue?

You could have a boost line with a leak causing it to go higher than it should though.

cheers for the input

ill check the lines again i replaced one coming off the fpr but that is all good now

my motor is not built for that power level and i don't want that amount of boost which is the root of my concern

my 755 cc injectors and haltech - rail etc etc all go in in a week or so but regardless of that id like to be able to have some sort of control

and seeing the boost that high with the bc switched off (im sure the solenoid is dead) it still spits out that much boost which i can only see being the actuators

ill have to research a bit more i guess

[JonnoHR31]

bypass the solenoid and run lines directly to the actuators and see what boost you get. other way to test is to use a compressor/bike pump and gauge to see what pressure they open at.

[Rolls]

if it isn't tuned for that boost then jesus christ don't boost it! could very easily pop the motor if the tune isn't set up for those load levels.

find out asap and get it sorted.

also haltechs are crap, get a better ecu.

[DAS KAMU]

well i have it now so i better install it

cheers for the info

ill try a by pass in the morning

[Rolls]

sell it and get a proper ecu

is it currently tuned for that boost? if so what ECU ?

sorry thats not financialy viable for me to throw another 2 grand away

wish i could but i cant

ill post how i go in the morning

thanks again for your input

[DAS KAMU]

all is in place hoses etc

will call garrett and discuss

[DAS KAMU]

Ok it seems the ebc solenoid has died and jammed right open

when i take it off i will look inside

I thought when you said it was all disconnected it wasn't physically inline with the turbo anymore, they should be a fail safe solenoid but if it jammed open then that makes sense.

oh i meant i disconected the in car controler sorry

yep i have also checked the power to the solenoid there was a reading

so the swing valve is jamed open

i cant wait to open it to learn what is inside after i remove it

dude you are getting "unlimited" boost which means either a line is off somewhere or you have not hooked up the system properly. what's happening is no pressure signal is getting to the wastegates so they are staying shut the whole time. you need to check, and recheck your hoses. no way would the wastegates come set over 1.5bar. well it's possible but extremely unlikely. it's a plumbing problem.

if the solenoid is jammed open it's possible it's bleeding off so much air that you are getting unlimited boost but the solenoid from memory should be NC type so if not working it should be closed and you just get base boost.
