no boost!

Hey guys, I was just driving my zed and I had it in 2nd and floored it. It boosted away but then all of a sudden lost all boost. Now my boost guage reads zero in any gear at any rev. Other than that the car runs fine but is just slow . Any ideas where to look first?

Cheers!

 

so does the guage go to -7 when off throttle? If not then you've popped the hose off the sender and your loss of power is placebo.

If it does go to -7 on the guage and won't climb above 0, then likely your wastegates are shot and held open.

If it's running rough then you've likely blown of a Intercooler pipe somewhere along the line.

 

It goes to -7 but wont go past 0 when I push the throttle. There is a definite huge loss in power, no question about it. I have 2 GFB Mach 1 Blow Off valves that are about 2 years old, u think they might be the problem?

 

if there stuck in the open position they could cause a massive leak !! boost leak time

 

If a boost leak, you'd hear it over the engine for sure

 

Thread digging , because mine is doing this as well
Plenty of vacuum, but will not boost above to the plus side.
Now i was stuffing around putting some gauges in on the weekend, could i have done something Electrical to cause this???
If so where to start looking???

Help

Hmm, I cant think of anything, boost solenoids disconnected should still make around 7 psi. :\

 

I still havnt solved my issue. I saw another thread was started a few days before mine and the guy had the same problem. It's spreading! I couldnt find any obvious boost leaks. It may be worth noting that the day before this happened I had my a/c regassed.

 

This sux!!!!
Only noticed this today, and its shitting me off already.
Crawled under the car nothing amis i can see, from top , nothing also.

Clue!

Clue!!!

Passenger turbo inlet/outlet pipes and/or vac hoses disturbed?

Did they remove any turbo piping? :mad2:

PS: I'll try to get to it this weekend if not too late.

 

I think quarantine is the best thing to do in these situations before the problem spreads

 

Gee thanks Mark

No bov's , still stock recircs.

oh no. Just heard from the mechanic and apparently one of my turbos has seized. Not sure what to do now.

 

rebuild or replace, but do both

 

And find out why the old one failed...

 

Seized turbo's usually mean a lack of lubrication.

 

What are the usual signs and symptoms of turbos needing rebuild or being replaced?

 

Ive decided to get both my stock turbos rebuilt. Should I expect a small performance increase from rebuilding a 20yo turbo?
