Re: 14b spools but no boost
 

Well up to today, I was running an open down pipe, but now I have a full 2.5", so I know it isn't a plugged exhaust. I have checked for all kinds of boost leaks everywhere, and at this point if a spot is leaking i am blind. The BOV gasket is brand new, as with the BOV itself. The only thing that doesn't check off is the wastegate sealing surface, what do you mean by that? I searched and I came to conclusion that you mean the part inside the exhaust housing in which the flapper mates to the exhaust passage...is that correct? It's too hot to pull off right now, Ill try in the morning. Thanks for your help guys, much appreciated.

I had this same problem on my last set up, and its fix was pretty simple. Take off the wastegate. and go to the hardware store. Buy a pack of springs. youll want a few because the tension on the spring is whats going to set max boost. Take the spring and hook it throug the actuator arm, take the end and, while keeping it straight, put it into an empty bolt hole or something. I tryed this and sure enough I was boosting 12 psi with no issues. You can run it like this ( I did) or you can get a new wastegate if this fixed your problem

I opened up the exhaust housing this morning and saw that the flapper was not sealing tightly against the mating surface because the arm was too long. So I grabbed 3 washers, and stuck them between the bold that holds the actuator to the cold side and now it seals tightly. :1 sometimes u just feel stupid when its something so dumb.

also look inside the ex. housing and see if its cracked along the wastegate, it tends to crack and let boost slip out

dude thats what i told you!!! thats the exact same problem i had....and the exact same solution i used. glad to hear its fixed.

Re: 14b spools but no boost
 

Yeah you told me that it was that way because of how you had it mounted, I thought you meant that you had relocated it, and needed further modification.

So is there something in there on the DSMs too or is it just a problem that comes with age? The 14b pwns the rhb5. I now experience a pull all the way to redline.
