14b spools but no boost
I got a good one here. I have a 14b turbo, on a z6. I hear it spool but I do not feel it at all. I get to about 5k in 2nd and shift and the blowoff valve is just barely audible. The car doesn't feel like its boosted at all. I have checked every coupler, tried disconnecting the wastegate, and it still does not boost. This is my 2nd setup on this car so I'm not a total newb to this, but I'm baffled. Any ideas?

Re: 14b spools but no boost
maybe wastegat stuck open a little??? sounds like a boost leak

Re: 14b spools but no boost
just re-check all the pipes and the vac lines... could be a tear in those, too. When you say you disconnected the WG, did you just take off the vac lines? If that's the case and it was still not boosting, like the guy above me said, the WG could be stuck open a little.

Re: 14b spools but no boost
check to make sure the wastegate isnt forcing open the flapper, by the way you have it mounted...taht was my problem.
you are giving it full throttle arent you ^-^ |
Re: 14b spools but no boost
The little arm that controls the flapper which the actuator connects to is shut. And I can pull the actuator arm out by hand but not easily so that appears to function at least somewhat. There aren't any vacuum leaks either. I have checked the couplers 10x over. How big of a hole would u have to have anyway, to lose 8 psi?

Re: 14b spools but no boost
did you actually check every joint with soapy water? post up some pics of your vaccum lines or explain how they are routed.

Re: 14b spools but no boost
Yes sir, I checked every weld and coupler with soapy water. I have the actuator line going to an inlet welded to the pipe that's bolted to the compressor. Is there another spot preferred for that? And the bov is T'd with the intake mani and fpr.

What management are you running?
Its definately a leak somewhere or its got to do with the wastegate |

Re: 14b spools but no boost
plugged exhaust, cracked wastegate sealing surface (bad on 14b's) boost leak, exhaust leak. check these again and get back to us ;)
