I read that the top part of the wastgate (delta gate) is for a boost controller and the side goes to a vaccuum source. The person who installed this for me says that he can not adjust the wastegate and it is stuck. Is it because it is connected wrong (top and side)? Any opinions would be appreciated. Revhard Stage 2 on a B16. I will try and attach a pic.

if u don't have a boost controller, nothing connects to the top port of the deltagate wastegate

 

So I guess the connection is backwards? It looks like the top is connected to the intake manifold. Also, how can you tell if the waste gate is open at idle?

 

if the wastegate is open at idle you'll hear it lol

it will sound like you have open exhaust.

put the hose from the intake manifold onto the bottom port and be done.

I wonder where the bottom is connected to? Yeah, when I rev the engine, I hear a weird throaty sound. I guess that's the sound you are talking about!!! lol

 

that would be it

 

take the hose off the top and plug it @ the mainfold. if you want more boost just sink the screw but it should only go as high as the number on the sticker but dont go crazy I've seen a 10 psi spring go 15psi

 

So, iF i dont have a boost controller nothing connect to the top?do i just plug the top off with a rubber cap?and as the side of the wastegate connect to my charge pipe?plmk thanks

 

yeah, u only need to connect the side (not top) to the intake mani, the top is just for boost controller...

 

What do you plug it with? Also, what happens if you drive and the wastegate remains open?

you leave the top open no need to plug. If the wastegate remains open you'll wont build **** for boost for a long while into the rpm band.

the wastegate will open when you reach the desired boost level.

Well, when I drove it, with the way it is set up, it went up to 12 psi!!! The sticker on the wastegate said 7 - 9.

 

ok ..i left the top open and side i hook up to my charge pipe ..is that how it suppose to go?

 

from the side of the w/g the pipe i connect to is ..the pipe that connect to my turbo

 

boost cannnot be adjusted on the deltagate
it is regulated by a spring
you would have to switch the spring out

but the wastegate vacuum ports should be:
top left open atmosphere if no boost controller
side goes to turbo like shown in the picture

that pipe that lead into the intercooler

 

Isnt the boost adjustable on the deltagate by a screw????

 

any1 have a 5,6,or 7 psi boost spring laying around..ill buy one ..i am stuck with a 10psi spring..any1 have one please email me at alexngo47@attbi.com or pm ..thanks

 

So the way it was set up, both the top and side connected, is that why i was boosting at 12 instead of 7 - 9 psi?

 

yes, disconnect the hose from the top port on the wastegate and either remove the hose and cap the tee that it is coming from, or plug the hose. I would cap the tee.

 

yes its because u have both connected..i use to run it like that..but now i took the top off and just connect the side to my turbo.it now run at what ever spring u hav ein htere

 

So how does it have more boost than what is stated if both are connected?

 

If you have a boost/vac reference connected to both ports, when you go into boost, the two signals will cancel each other out, keeping your wastegate from opening.

The top port of my d/g is connected to my EBC, the side port is connected to my compressor housing:

 

the side of my delta gate is connected to the intake manifold and the top part is connected to my TVVC manual boost controller. The side of the turbo is also connected to my manual boost controller.
