how can you tell if the wastegate is working? My lude won't boost. I was boosting the other day. I have a greddy Profec B hooked up and I turned it off but still no boost. my wastegate is a TIAL 35mm.

Check all of your vacuume lines to make sure that they are connected.Make sure the line going to your boost gauge is hooked up properly and doesn'r have a kink in it.Just double check all of your connections.Have you changed anything on the car between the time it was working and the time it stopped working?

i've check everything, i haven't change anything. does your BOV suck in air? Mine does. I a HKS racing BOV.

did you check to see if the wastegate is stuck shut?

check the spring setting in your wastegate.. ...

i checked the wastegate last night and it seems to be closed. The spring setting a .65 bar spring. I can hear the turbo spool but no boost? Thanks for help guys.

I had the same problem on my 2000 civic Si with the Drag kit and a Tial 35mm wastegate. The problem was two fold. first, the wastegate was staying open because of the tight fit of the large washer below the valve ( you know what I'm talking about?). does the exhaust sound loud all the time? then you are definately running it open. second you probably have a pipe that came disconnected when you were boosting. it took me a while to get on my hands and knees and look , and I felt like such an idiot when i saw one of my pipes had come undone from the silicone hose. check it out and let me know.

I check the washer and it is seated correctly, I haven't checked the IC piping yet. Have to do that when I get back in a week. But could it be the BOV? Thanks.

 

[serialKilla]

what BOV are you using? do you still hear a "swoosh" when you change gears?

 

[h23zero]

I have HKS racing BOV and no i don't hear it "SWOOSH" no more , But the turbo spools I know that for sure. I was just thinking if the BOV might be stuck open and bleed off the boost. If I remove my vaccum line to the BOV the BOV should close right? Of course I won't run the car without the BOV.

also make sure all yer piping is hooked-up....my intercooler pipe came loose once and my turbo wasnt boosting.

 

[serialKilla]

the turbo will still spool even if you don't have the piping hooked up. does the turbo sound a little lounder? it may be becase the piping is loose and you can hear the turbo better. that's what it sounds like to me.

 

[h23zero]

no, the turbo spooling sounds the same. there is no increase in noise level. I have to wait to check the IC pipings, though.
