OK, a while back I posted that my alcohol injection wasn't working anymore (though it might be the pressure switch) and I couldn't hear my BOV. On top of that I was having boost control problems. It happened shortly after I was running against this RSX. Anyways during one run with him I heard a little pop-type sound from my engine bay.

After that my boost stayed constant at around 5 psi so I thought somehow something got fixed by itself. However like I said above my bov and al inj weren't working.

Today I decided to double check and make sure my boost gauge was working correctly. I tapped in my buddies mechanical autometer one and sure enough, no boost. I took it up to the highway and redlined it through 3 gears and saw it only went up to a 1 or so. While my other one was reading at 5psi.

My question is why am I not getting any boost. I know the gauge is shot so I'll have to call autometer about that one but why no boost? I can still hear the turbo spooling up. Could that little "pop" sound been the flapper valve breaking or staying open constantly so the exhaust isn't getting re-routed back into the turbine blades? Any suggestions would be appreciated before I rip off the downpipe and check myself.

Start with the basics, check the pipes and make sure one didnt pop off.

Also check to make sure the wastegate is not being held up by anything. Either a pipe blew off or the wastegate is stuck open...

Well all the piping is still connected. I'll have to look at the wastegate more tomarrow. Thanks guys.

did the wastegate actuator rod come off ?

Yeah because that will def bring you down to 0 psi!!! I did that when I had to send my fuel system out lol...

But yeah, like others said... It's either a blow charge pipe, or the wastegate is stuck open or the rod is disconnected.

put hair spray on the ends of the charge pipes if they're not beaded...they're a biotch to get off but its really effective

Lower intercooler pipe blew off but I didn't notice it cause it was so close to the coupler that it looked attached. Dumb mistake, gonna have to look harder before I ask questions next time.
