Nick378 Posted September 23, 2008 Share Posted September 23, 2008 I guess this is the oem boost solenoid but i care about the little nipple without any hose. What is it and do i have to put a cap on it? I guess it's been like that for a long time but i've had a boost trouble for 5 weeks now and i' trying to figure it out! The boost is inconsistant, it goes up to 12 psi, then come back to 8 psi within 1 second when i am full open throtle. Sometimes, it won't do it. I tried with the boost controller (greddy profec b) in of mode and it seems to run ok. Anyway, do i have to put a cap on this little free nipple? Ps. Don't mind about the pink hose, it won't stay there lol...

(B1) MR_fanny Posted September 24, 2008 Share Posted September 24, 2008 you dont have to plug, you could even remove it altogether if you want. your greddy is controling things now. is the top hose on the stocker just a dummy hose or does it actually lead to somewhere? Id be optimising your hoses to, as you said that pink one is deff too long and all over the place. do you know how to adjust your ebc? you might have to adjust the settings. are you after 12 psi or just 8?

It actually lead to a 1" black metal hose and i have no idea what is it! I know how to adjust it, well i think i know... I was after 12 psi but anyway, the car will be stored in 2 months and it's cold as shit outside. I think shut down the boost controller and will adjust all my things next season. Still, i would like to find the issue lol.

Munkyb0y Posted September 24, 2008 Share Posted September 24, 2008 (edited) the top hose on the stock solenoid leads back to the intake. block that hose off. you can leave the solenoid there with no hoses attached. thats fine also, shorten that pink one. the shorter the pressure lines, the better Edited September 24, 2008 by Munkyb0y Link to comment https://www.sau.com.au/forums/topic/237349-vacuum-question-rb25det-what-is-this/#findComment-4152684 Share on other sites More sharing options...
